Diagnosing Cancer’s Chaos
By Rob Mitchum When a pathologist peers into a microscope searching for telltale signs of a dangerous cancer in a tissue sample, the first clue is often an aesthetic one. “In the normal tissue, there is a beautiful order,” said Thomas Krausz, MD, FRCPath, director of anatomic and surgical pathology at the University of Chicago Medical Center. “In cancer, depending on how aggressive it is, there is chaos.” A cell can become a tumor through many routes, growing uncontrollably and invading surrounding areas with, as Krausz puts it, “no respect for its neighborhood.” And as the electron micrograph images on these pages show, cells that have become cancerous can take on shapes that are both fascinating and horrific: sprouting tendrils and vesicles that disrupt normal symmetry and reflect inner turmoil. For surgical pathologists charged with determining the diagnosis from a biopsy, the story is rarely so simple as the isolated, cultured cells pictured here. In some cases when a piece of potentially cancerous tissue is taken intraoperatively from a patient, pathologists have a mere 20 minutes to prepare the sample with freezing and stains, examine it with the naked eye and microscopes, and answer several critical questions: Is the tumor benign or malignant? How far has it spread? Has it invaded surrounding blood vessels? Those answers are crucial to a patient’s care, determining the course of treatment both immediately through the size of the area removed in surgery and long-term through the use of radiation or chemotherapeutic drugs.

“At the end of the day, cancer is diagnosed by pathologists,” Krausz said. “Without a pathology diagnosis, there is no appropriate cancer treatment.” Newer techniques, like immunohistochemistry and molecular pathology that help categorize tumors by identifying aberrant genes and proteins, have changed pathology and have proven essential in the developing era of personalized medicine. But most decisions are still made with the microscope, a centuries-old technology that — combined with the experience of a pathologist who has viewed hundreds of thousands of slides — remains the most powerful tool in classifying cancer. For the trickiest cases, where a firm conclusion eludes the initial pathologist, the department’s extensive knowledge across different organ types and diseases is pooled. Daily meetings, in a room equipped with a special microscope through which 16 pathologists can simultaneously view a sample, help pathologists to collaborate, resolve these difficult cases and reach the proper diagnoses. “There’s no room for error; we have to be 100 percent accurate,” said Husain Sattar, MD, assistant professor of pathology. “We think multiple times before we sign and release our final diagnosis.” “There is only one diagnosis,” Krausz added. “The correct diagnosis.”

Letter from the Editor:
Coworker Donates Liver to Child
It’s not often that scientists call to say that a story in Medicine on the Midway made them cry. But that’s what Deberah Simon told me when she called to ask if I could forward a letter she’d written to Alyssa Smith and her mother Teri. Alyssa, as readers may recall, was featured on the cover of our fall issue on the 20th anniversary of the first living-donor liver transplant performed in the United States. The transplant occurred at the Medical Center when Christoph Broelsch, MD, then chief of the Medical Center’s liver surgery service, and a team of doctors and nurses removed 2-year-old Alyssa’s diseased liver and replaced it with one-third of her mother’s. Now, 20 years later, Alyssa Smith graduated college on May 9 with a degree in social work and is exploring careers that involve children with transplants. I was so touched by Deberah’s letter and her connection to Alyssa — Deberah was a scientist who worked to prove that a living-donor liver transplant was possible — that I asked if I could share her letter with readers. I think you’ll agree it’s a perfect example of how “translational research” at the Medical Center connects scientists to doctors and then doctors to patients.
It’s this kind of advanced care we are highlighting in this issue: scientists and doctors engaged in breakthrough cancer research, translating discoveries in the lab to treating advanced cancer. Here at the University of Chicago Medical Center, we’re finding answers where others have found roadblocks. I hope these stories inspire you, and I look forward to hearing from you. Sincerely, Cheryl L. Reed Editor firstname.lastname@example.org
Raquel Allen was 3 months old when she was diagnosed with biliary atresia, a congenital condition that affects the liver’s ability to secrete bile. Occurring roughly once in every 15,000 births, the disease causes serious and, eventually, fatal liver damage if left untreated. Raquel’s parents were told in May 2009 that their daughter would soon need a liver transplant. A living-donor transplant was an option, but neither Coral Grinage nor Melvin Allen, Raquel’s parents, matched Raquel’s Type O blood, a prerequisite for successful transplantation. “After we found out we weren’t a match, we started telling people…just kind of putting the word out there,” Grinage said.
One person she told was Catherine Ortiz, a 27-year-old Alsip woman who worked with Grinage. Ortiz asked questions, discussed the matter with her husband and decided to volunteer to be Raquel’s liver donor. On August 25, 2009, Ortiz donated part of her liver to little Raquel during an eight-hour, living-donor liver transplant performed at Comer Children’s Hospital at the University of Chicago. The transplant occurred nearly 20 years after the procedure was performed for the first time in the United States by doctors at the Medical Center. Now, the procedure is performed 12 to 15 times a year at the hospital.

Ortiz recovered quickly from her surgery, returning home after two days in the hospital. Meanwhile, 11 days after surgery, Raquel celebrated her first birthday in her Comer Children’s Hospital room. Raquel’s father said those extra years will be the best birthday present his daughter could ever receive: “What better gift to have than the gift of life?”
When Comfort Food Becomes Dangerous October 30, 2009 Dear Alyssa and family, I came home from work today, opened the mail and there was the current issue of Medicine on the Midway with your picture on the cover, and the headline “A Medical First, 20 Years Later.” I didn’t have to read the article to know what they meant, for, you see, I was part of the team that did the research that led to your surgery. My work was a decade before the actual surgery, so I missed the news when it occurred, and I never knew who it was, only that it was a little girl, and that it was successful. When I saw your face, I sat in my kitchen and cried and cried; I was so overwhelmed — and I know this sounds silly — that you were real and alive and such a beautiful person. In the late 1970s, I worked in Dr. James Boyer’s hepatology research lab. I was a “lab rat” — a chemist who worked in medical research. At the Deberah Simon time, the idea was around that you could probably take out a portion of a healthy liver and that the liver would re-grow, or at least that the donor would be able to tolerate the removal and lead a normal life. My job was to try this with an animal model and carefully document the results. There were three of us who learned to operate on rats and then document the chemical and morphological changes. It was incredibly meticulous work, challenging on so many levels. Everything was so tiny, and the changes were so small. We worked for a long time just to be able to complete the surgery successfully. After the difficult work of extracting the sample, it had to be analyzed, and that job was mine. The sample had to be kept cold, and an ice bucket on a bench top didn’t work (believe me, I tried). I set up shop in a cold room, which was a small, closet-like room like an old-fashioned meat locker, dim and damp, with a huge thick door and latch, and I

did all the chemical work in there. I’d work for an hour or so, then come out and sit on a big radiator under a window until I thawed out, then head back in to work some more. The sample was first run in a blender, then all the cellular components had to be separated. We did this by making a layered column of sucrose solutions of differing densities, then putting the extract on top and spinning it in an ultracentrifuge. I did this day after day, for months, as we slowly built up evidence that it worked. I tell you about this in some detail because I think you’ll be interested in how I’ve used this experience over the years. I teach chemistry at Whitman College, in Walla Walla, Wash. The very first lab I designed, and the one that kicks off the start of fall semester every year for my freshman class, is “Sucrose Density Gradient Columns” — the lab I wrote using the technique I learned doing the hepatology research 30 years ago. And every single year I tell the story of working in the cold room, and what a tiny little piece I played in a much bigger story, and of how you never know where life will lead you. But in all these years, I’ve never had a name or a face to put with this story, until now. And that’s why I sat in my kitchen and cried to see your smiling face. I wish you, and your incredibly brave family, the very best life has to offer. I feel very privileged to have played even so tiny a part in all of this.
Anyone who’s ever eaten a bag of chips in one sitting knows the truth of the slogan, “Betcha Can’t Eat Just One!” But chips may not be the only food capable of putting you in an overeating zone, as new research finds that chocolate or water can actually blunt pain. When rats are eating or drinking, they are slower to move their feet away from a hot light bulb, according to research conducted by Hayley Foo, PhD, research associate professor of neurobiology, and Peggy Mason, PhD, professor of neurobiology, at the University of Chicago. The results suggest rats are so focused on completing their meals that their brains make them less susceptible to distractions. “It’s a strong, strong effect, but it’s not about hunger or appetite,” Mason said.
“If you have all this food in front of you that’s easily available to reach out and get, you’re not going to stop eating, for basically almost any reason.” In the wild, where food is scarce, ignoring distractions while eating is a good skill to have. But for modern humans, where the next meal is only as far as the nearest supermarket, an unshakable focus on finishing the food in front of you and drowning out distractions can be unhealthy. But the study may also suggest positive uses for pain-blunting effects of eating or drinking. Previous studies have shown that giving sugar water to infants can reduce the pain of an injection, a trick frequently replicated in pediatric offices. A piece of good news from Foo and Mason’s study is that the substance used for this
pain relief doesn’t have to be alcoholic, or even caloric — water was just as effective as chocolate chips at blunting pain in rats. Only substances that the rats did not naturally enjoy, such as a bitter quinine solution or very salty water, failed to trigger the reduced sensitivity to pain. The results excited Don Katz, PhD, an associate professor of psychology and neuroscience at Brandeis University in Massachusetts, who said it suggests an important biological purpose for taste. “They’re saying that the purpose of the taste system is to give an animal a cue that helps it decide what stimuli it should or shouldn’t pay attention to,” Katz said. “It’s really important for them to know when they should stop eating if they don’t have to stop eating.” Foo and Mason traced the pain relief effects of eating or drinking to the raphe magnus, an area of the brain stem responsible for reflexive actions, suggesting that this effect is as automatic as sweating during exercise. “You’re essentially at the mercy of your brain stem, and the raphe magnus is part of that,” Mason said. “It tells you, ‘you’re going to finish eating this, whether you like it or not,’ just like you sweat while running, whether you like it or not.”

Medical Center physicians offering services at the new Vascular Institute of Chicago are, left to right: Tina Desai, MD; Giancarlo Piano, MD; Christopher Skelly, MD; Hisham Bassiouny, MD; and Daniel Katz, MD, chief of Vascular Surgery at Weiss Memorial.
A New Vein of Care for Vascular Disease University of Chicago Medical Center physicians now offer their services at the new Vascular Institute of Chicago at Weiss Memorial Hospital, bringing experienced vein and artery care to the city’s North Side. The new institute provides a home for all vascular services, using Medical Center physicians to help diagnose patients and create tailored treatment plans based on the patient’s condition, medical history and lifestyle. For patients familiar with the University of Chicago Medical Center, Weiss offers the same technology and expertise as those on the main campus, said Hisham Bassiouny, MD, medical director of the new
Vascular Institute and chief of the Section of Vascular Surgery and Endovascular Therapy at the Medical Center. The new institute offers state-of-theart diagnostics and minimally invasive, innovative treatments. Bassiouny is the only Chicago-area surgeon who is FDAapproved to use the da Vinci® Surgical System for lower extremity vascular reconstruction. “This unique capability exemplifies our commitment for continually evaluating emerging technologies which can best improve outcomes for our patients,” Bassiouny said. “Our enterprise thrives on successfully managing the most complex of cases, and we are thrilled to offer
the Chicago North Side our leading edge services for vascular disease management.” The Medical Center has an established relationship with Weiss in regard to vascular care. In 2008, the two hospitals collaborated on establishing the Vein Clinic at Weiss, which has successfully treated varicose and spider veins, deep vein thrombosis and other conditions for many years. As a part of the Vein Clinic, the Non-Invasive Vascular Laboratory excels in using ultrasound and doctors’ expertise to safely and accurately diagnose vascular conditions. This laboratory is nationally accredited and unparalleled among Chicago’s community hospitals.
In Praise of Genetic Diversity It was an intriguing find for evolutionary biology: two genes involved in the size of the developing human brain were subject to selection in recent human history, and may still be evolving today. But when Bruce Lahn, PhD, a University of Chicago professor of human genetics, published this discovery in 2005, he knew that it might create controversy alongside excitement. A variant of one of the genes, microcephalin, occurred less often in sub-Saharan Africa than other regions of the world, while the other gene, ASPM, had a variant seen commonly in Europe, North Africa, the Middle East and South Asia but less often in East Asia, Native Americans and Sub-Saharan Africa. Lahn suspected extremists would distort his evidence of these genetic differences to inappropriately justify racist beliefs. What he didn’t expect was that credible scientists would also distort his findings, and that some would actually question whether his research should have even been performed in the first place.
After that experience, Lahn decided that both the scientific community and society in general needed a new moral framework to deal with rapidly growing information about how genes differ between individuals and groups. In an
An illustration of a marked chromosome.
opinion piece published in the journal Nature last October, Lahn and co-author Lanny Ebenstein, PhD, of the Department of Economics at the University of California, Santa Barbara, argued that researchers must embrace and even celebrate the idea of genetic diversity.

“Instead of trying to suppress the science, we should try to build a moral consensus that is constructive to the overall well-being of the species,” Lahn said. Lahn argues that the idea that there are no significant differences between ethnic groups is in fact more dangerous than the potential misuse of human genetics research. Scientists may be pushed away from important research questions instead of adding to growing evidence that the grouping of individuals can be medically useful in the growing fields of personalized medicine. (See the mapping genes article on page 12.) The solution, Lahn and Ebenstein argue, is to convince people to accept genetic diversity as much as they have grown to appreciate cultural diversity in recent decades. “Genetic diversity is a strength, not a weakness, of humanity,” Lahn and Ebenstein wrote. “On the whole, humanity has been and will be stronger, not despite our differences, but because of them.”
Rodney L. Goldstein, an accomplished Chicago business executive and longtime leader in the university community, has been appointed as chair of the University of Chicago Medical Center Board of Trustees. Goldstein succeeds James S. Crown, who served as interim chair of the Medical Center Board. “Rod’s background in planning for the success of varied enterprises will be
invaluable as the Medical Center enters a critical period of growth and new opportunities,” said Everett E. Vokes, MD, interim dean of the Biological Sciences Division and the Pritzker School of Medicine, and interim CEO of the Medical Center. Goldstein joined the Medical Center Board in 1992. He has been a Trustee of the University since 2006.
University Research Stimulated by Federal Recovery Act Funds When Barack Obama promised in his inaugural address that his administration would “restore science to its rightful place,” researchers across the United States hoped it was more than mere rhetoric. After years of flat budgets from scientific funding agencies such as the National Science Foundation (NSF) and the National Institutes of Health (NIH), many laboratories were in dire need of funding to continue projects and launch new experiments. Eight months into his first term, President Obama delivered on his promise to the scientific community with the American Recovery and Reinvestment Act, which included more than $5 billion directed toward science and medical research. At the University of Chicago, more than 150 researchers received Recovery Act money from the NIH, NSF, National Endowment for the Arts and the Department of Education, totaling nearly $72 million campus-wide over two years. An estimated 79 jobs will be created or preserved due to the funding, according to a university calculation. The majority of that money was awarded to researchers at the Medical Center and in the Biological Sciences Division, with more than $43 million from NIH grants for fiscal year 2009 and an additional $1.3 million from the NSF. An additional $17 million will be awarded by the NIH in the second year of the grants. Some grants as small as $10,000 will help laboratories with day-to-day supply and personnel costs, while several multimillion dollar grants will launch new nationwide clinical
trials administered from the University of Chicago. The largest grant, at $5.6 million, was designated to fund the EVE project — the “mother of all asthma studies,” according to Carole Ober, PhD, professor of human genetics and obstetrics and gynecology. Ober and Dan Nicolae, PhD, associate professor of genetic medicine, statistics and human genetics, are primary investigators on the project, which will coordinate researchers at 10 institutions to perform genome-wide association studies on more than 30,000 subjects. The researchers hope to find novel gene variants associated with asthma that will lead to new treatments. “We’re excited to receive the funds to launch a project that may open promising new avenues for asthma research,” Ober said. Another multicenter clinical research effort will be directed from the Medical Center by Jerry Krishnan, MD, PhD, associate professor of pulmonary medicine. CONCERT, a collaboration among six health care institutions, was given nearly $4 million to begin studies comparing treatments for chronic obstructive pulmonary disorder, which is expected to be the third most common cause of U.S. deaths by 2020. Basic science research also received several large grants from the Recovery Act funds. Kevin White, PhD, professor of human genetics and ecology and evolution, received two $900,000 grants to help the NIH ENCODE project create an encyclopedia of DNA elements. A new technique created in White’s laboratory will be applied to the genomes of humans and Drosophila, the fruit fly that has historically been an important scientific model for genetic function. Summaries of all university projects that received Recovery grants can be found at http://arrafunding.uchicago.edu Esra Tasali, MD, received $1 million to research the relationship between sleep apnea and the onset of Type 2 diabetes.

BRIEFLY Tiny dinosaur, big discovery The smallest dinosaur ever discovered in North America was recently identified from bones that have been housed at the Natural History Museum of Los Angeles County. Originally discovered in Colorado in the 1970s, the bones have been in storage ever since.
Fruitadens haagarorum stood only four inches tall, weighed two pounds and was 28 inches long. The agile, fast-running omnivore lived 150 million years ago during the Late Jurassic Period, which makes it one of the earliest dinosaurs. The new species was identified from parts of skulls, vertebrae and limbs of four specimens. Fruitadens belonged to the heterodontosaurids, an important group of dinosaurs previously unknown in North America. The species was identified by Richard Butler, PhD, of the Bavarian State Collection for Paleontology in Munich, and his team. The team, along with Laura Porro, PhD, postdoctoral research associate in Organismal Biology and Anatomy at the University of Chicago, discovered the species.

Scorpion Venom Keeps Brain Tumor in Check A drug derived from scorpion venom appears to be helping a 49-year-old Tinley Park, Ill., woman beat the odds. Diagnosed in December 2005 with a deadly glioblastoma multiforme, Donna Van Ryn has lived almost three times the median survival of 15 months — and feels fine. She has been through two brain surgeries to remove her cancer, which oncologists suspect is the same type as the late Sen. Edward Kennedy’s. She went through aggressive radiation and chemotherapy, and two clinical trials of investigational drugs. But the treatment to which she is currently responding
involves a medication fashioned from a scorpion’s sting. Van Ryn says she now feels better than she ever has since noticing her first symptoms, and her scans show no evidence of recurrent disease. She walks three miles a day and just started a new job as a secondgrade teacher. “I’m pretty much back to my normal self,” she said. The drug, known as I131-TM601, is produced by TransMolecular, Inc., a small biotechnology company based in Cambridge, Mass., that focuses on targeted therapies for cancer. It combines radioactive iodine (I131) with a piece of a toxin (TM601) derived
from the venom of the Israeli desert scorpion, ominously referred to as “deathstalker.” The toxin fragment recognizes and binds to receptors found on the surface of glioma cells while bypassing normal, healthy cells. It is given intravenously, enabling it to travel throughout the body and target tumor cells. Within the brain, it “shockingly homes right in on glioma cells,” said trial director Steven Chmura, MD, PhD, radiation oncologist at the Medical Center. “We often talk about targeted therapy, but this is far more targeted than most of what we see.”
Team Pairs Cardiac and Vascular Specialists For decades, physicians at the University of Chicago Medical Center have provided patients with state-of-theart diagnostic and treatment services for all types of aortic diseases. The University of Chicago Aortic Specialty Team (UCAST), formed in 2009, ensures that patients who require elective or emergent intervention for complex aortic conditions benefit from expedient and coordinated care from a multidisciplinary team of cardiac and vascular specialists. UCAST provides patients the most advanced care with both straightforward and complex aortic disease using minimally invasive approaches whenever possible. 1
The team recently cared for a 68-yearold man who came to the Medical Center with a large dumbbell-shaped aortic aneurysm involving the blood supply to the gut and kidneys (Figure 1), a dangerous bulge in the life-supporting blood vessel that can lead to fatal rupture. Using minimally invasive endovascular techniques best performed by highly skilled surgeons at an academic medical center, the team repaired the aneurysm in two stages. During the first stage, blood supply was redirected to the gut and kidneys utilizing a multibranched bypass around the diseased portion of the aorta, allowing continued blood flow and greatly 2

reducing the risk for liver, intestinal and kidney damage during the rest of the procedure. In the second stage, the surgeons deployed a specialized covered stent from the distal thoracic aorta to the iliac arteries. By diverting blood flow through the covered stent, the blood pressure and tension on the aneurismal aortic wall was virtually eliminated (Figure 2). The patient had an uncomplicated recovery and quickly returned to his usual daily activities. “This case epitomizes the strategy of the University of Chicago Medical Center,” said Jai Raman, MD, PhD, codirector of UCAST, “which is to develop and deliver techniques that treat high-risk patients with lower mortality, less trauma and shorter recovery time.” Hisham Bassiouny, MD, co-director of UCAST and chief of the Section of Vascular Surgery and Endovascular Therapy at the Medical Center, agreed: “Without access to the highest level of care provided by highly skilled specialists, this patient may have experienced significant organ damage, or, in the worst case scenario, death. We are pleased to be able to bring life-saving techniques to patients like him who require a collaborative approach to care.”
from every angle
By Rob Mitchum With contributions from Don Reneau and Susan Chandler Cancer has been a deadly riddle without a solution for centuries. The desperation to find a cure led to unusual theories from visionary scientists, such as Leon Jacobson, MD, at the University of Chicago in 1943. Observing that soldiers exposed to the chemical weapon mustard gas exhibited low white blood cell counts, Jacobson proposed that the toxin could be used to treat leukemias — cancers that produce an excess of those very cells. The experiments worked, and what we now know as chemotherapy was born. Many patients showed remission of their cancer when exposed to nitrogen mustard, the active ingredient of mustard gas, but at a price — the side effects were severe and unpleasant. A tool for treating cancer had been found, but it took the coarse strategy of using poison to cure. In today’s cancer treatment, the strategy is the same, but the tools are far more advanced. A cancer patient lies immobilized on a platform in a dark room of the Duchossois Center for Advanced Medicine. Silently, a meshwork of lasers crisscrosses his body, almost completely covered by a protective lead gown. Above his head, a mechanical arm glides in a semicircle, imaging the patient’s tumor immediately before firing beams of radiation from multiple finely calibrated angles calculated by a powerful computer. The procedure, Image-Guided Radiation Therapy, or IGRT, shares a purpose with the chemotherapy of nearly 70 years prior: to kill cancer cells with a destructive force. But rather than applying radiation broadly and damaging healthy cells along with cancerous ones, IGRT uses the latest technology to focus radiation directly at the tumor, minimizing collateral damage and side effects. The University of Chicago Medical Center and Joseph Salama, MD, assistant professor of radiation and cellular oncology, were the first to bring IGRT to patients in the Chicago area. But IGRT is only one of a multitude of breakthrough cancer treatments currently applied, researched, or developed at the Medical Center,
where more than 200 physicians and scientists constantly seek new ways to outsmart this deadly disease. “It’s not hopeless, and we are making progress,” said Ralph Weichselbaum, MD, co-director of the Ludwig Center for Metastasis Research at the Medical Center and chairman of the Department of Radiation and Cellular Oncology. Like the machinery behind IGRT, the Medical Center is attacking cancer from all angles, using every possible tool: radiation, genetics, drugs, surgery and medical engineering. With each new innovation, more cancers become treatable, side effects become less severe and optimism is restored for those stricken with the disease. “The University of Chicago Comprehensive Cancer Center really takes a multi-faceted approach that involves hundreds of individuals,” said Michelle Le Beau, PhD, professor of medicine and director of the Comprehensive Cancer Center. “One of the things that makes us so unique is that we have expertise in the whole scheme, from cancer detection to diagnosis to treatment.” The ultimate answer to the riddle of cancer has yet to be discovered. But the momentum is shifting — cancer death rates in the United States have fallen 1.6 percent each year since 2001, and 5-year survival rates for cancer patients have increased from 10 percent to more than 65 percent in the last 30 years. With recent genetic and technological discoveries bringing even more promise to the fight against cancer, researchers are optimistic that great strides will continue to be made. “These technologies simply were not available 15 years ago,” said Blase Polite, MD, assistant professor of medicine and an expert in gastrointestinal cancers. “Add to that the recent mapping of the human genome, one of the greatest scientific feats of the millennium, and we now can explore the very heart of the cancer machine and find ways to turn it off.”

“Tumors start out quite different from each other,” explained Geoffrey Greene, PhD, vice chairman for the Ben May Department for Cancer Research and co-director of the Ludwig Center for Metastasis Research. “But in later stages they become more alike and less treatable.” Greene’s research focuses on the activity of the estrogen receptors in specific types of breast cancer. In breast tumors, the absence or presence of these receptors dictates the type of treatment a patient is given — a model that researchers of other cancers hope to emulate. Greene’s characterization of how different drugs target the estrogen receptor has suggested new strategies for the treatment and prevention of breast and uterine cancer. (See the breast cancer article on page 15.) The laboratory of Marsha Rosner, PhD, professor and chair of the Ben May Department for Cancer Research — along with work by Andy Minn, MD, PhD, former assistant professor of radiation and cellular oncology now at the University of Pennsylvania — seeks to understand the genetic signatures of metastasis. The team looked for genes that could predict metastasis in the early stages of triple-negative breast cancer, the most aggressive form of the disease. Genes from over 1,000 tumors were analyzed, and new signaling changes were found that can serve as early warning signs about the metastatic potential of a tumor. Tumors with a high metastatic risk can then be attacked with more aggressive methods earlier in the patient’s treatment, to try to overwhelm the cancer while it is still vulnerable. New ways of thinking about cancer also may come from the Chicago Cancer Genome Project, an effort led by Kevin White, PhD, the James and Karen Frank Family Professor of Human Genetics and the director of the Institute for Genomics and Systems Biology. In partnership with Medical Center physicians treating and researching all types of cancer, White hopes to sequence at least 1,000 tumors to find new genetic patterns that can be used as markers for better treatment and diagnosis of individual tumors. “It’s a long road from having a piece of genome sequence to actually implementing that into patient care, but the path is at least clear enough that we can shine a
light down it and see the end,” White said. “If we know enough about the genetic basis of the tumors, we should be able to at least connect the dots and draw a path toward clinical trials, and if those work out, toward actually getting things into the clinic.”
Paving New Paths from Bench to Bedside Poised at the transition point between the laboratory and the clinic, drug trials determine whether the gradual process of basic research will bear fruit as a new strategy for cancer treatment. The process is one riddled with both successes and failures. A substance that kills cancer cells in a laboratory dish might have little effect in patients, or be effective in only a subset of cancers. For every successful new drug that has reached the clinic, dozens of failed compounds have fallen by the wayside. “You can never predict when something works in the lab, whether it will work for the patient,” said Everett Vokes, MD, interim dean of the Pritzker School of Medicine and Biological Sciences Division, and interim CEO of the Medical Center and an internationally known specialist in head and neck cancer. “It’s impossible because the two are never completely correlated.” Meeting those challenges requires both scope and ingenuity. More clinical drug trials are in progress at the Medical Center than at any other site in the Chicago area, with more than 300 trials open in 2009. Many of these trials are first-in-human studies, drawing upon findings developed through University of Chicago laboratory research. Experimentation goes down to the very structure of the trials themselves, with researchers who have overseen thousands of clinical trials seeking better tests to reveal the full therapeutic potential of a new compound. (See the clinical trials article on page 13.) Richard L. Schilsky, MD, chief of hematology/oncology at the Medical Center, also served as chair of the Cancer and Leukemia Group B, the largest and oldest cancer clinical trials group in the United States. Schilsky’s research has spanned from simple preventive measures to complex combinations of chemotherapy drugs. One trial tested the potential of taking an aspirin a day to prevent the development of precancerous polyps in patients at risk for colorectal cancer. Another developed a promising new drug combination for treatment of pancreatic cancer.

University of Chicago Comprehensive Cancer Center Founded in 1973, the University of Chicago Comprehensive Cancer Center (UCCCC) is one of two National Cancer Institute-designated Comprehensive Cancer Centers in Illinois. The UCCCC received its NCI designation because of its research in three major areas: laboratory, clinical and population-based research. The UCCCC has 220 members with peer-reviewed cancer research grants of about $98 million, and $25 million in non-peer reviewed grants and contracts. The University of Chicago has been a leader in cancer research for many decades. Its scientists have made groundbreaking discoveries that have led to advances in chemotherapy, hormonal therapy, gene therapy and bone marrow transplantation. Nobel Prize recipient Charles Huggins, MD, discovered in 1939 that cells were not autonomous and self perpetuating, as previously believed, but were dependent on chemical signals, such as hormones, to grow and survive. His discoveries offered researchers new perspectives on the behavior of hormone responsive cancers, and redefined treatment of metastatic cancers. In 1943, Leon Jacobson, MD, performed the first successful cancer treatment using chemotherapy, and demonstrated the potential of bone marrow transplantation. In the 2009 fiscal year, the pediatric and adult bone marrow transplant programs performed 180 bone marrow transplants. Janet Rowley, MD, who discovered recurring chromosomal abnormalities in leukemias and lymphomas, revolutionized the understanding and treatment of cancer.

Striking that balance also has been a research priority of Mark Ratain, MD, the Leon O. Jacobson Professor of Medicine and director of the new Center for Personalized Therapeutics and the associate director for Clinical Sciences in the Comprehensive Care Center. Research conducted by Ratain and colleagues discovered a genetic variant that predicts a patient’s toxic response to a drug called irinotecan, used as a common chemotherapy in treatment of colorectal cancers. A screening test for the UGT1A1 gene, which can predict the severity of a patient’s side effects to irinotecan, was made available to physicians worldwide in 2005. (See the mapping genes article on page 12.) Such a genetic test seeks a “biomarker” for improving cancer treatment, an objective measure that can guide physicians in fine-tuning the medication each individual patient receives. Michael Maitland, MD, PhD, is testing even simpler biomarkers that can convey information quickly to physicians about the effectiveness of a drug class called angiogenesis inhibitors. These drugs are designed to prevent the formation of new blood vessels that facilitate tumor growth, but may cause high blood pressure in some patients. Maitland, medical oncologist and assistant professor of medicine, proposed using that side effect as an informative signal for the proper dosing of drugs such as sorafenib or sunitinib. By measuring blood pressure on the very first day of treatment with an angiogenesis inhibitor, physicians might quickly find the most effective and safe dose of the drug. That method is now being tested in clinical trials with various drugs to see if the protocol can improve patient outcomes. “These are the newest investigational drugs and often we are the only place in the city that can provide them,” Le Beau said. “We have the ability to treat patients with unique forms of therapy that they may not have access to otherwise.”
Maximum Effectiveness with Minimal Invasion Surgery may be the oldest known treatment for cancer, based on the early theory that a tumor represented a deadly interloper in the body and that the life of the patient depended on somehow getting it out. Surgeons these days bear no real comparison with their early predecessors, yet surgery remains a first, critical line of defense for many cancers and in most instances the only proven curative modality. Using state-of-the-art techniques, 10 University of Chicago Medicine on the Midway
such as minimally-invasive and robotic surgery, surgeons are increasingly attempting to achieve the same cancer outcomes but with approaches that may result in less pain and shorter hospital stays. “Surgery is an integral part of the treatment of cancer,” said Jeffrey Matthews, MD, the Dallas B. Phemister Professor of Surgery, chair of the Department of Surgery and dean for clinical affairs. “For many types of cancer, surgery remains the only cure.” Many cancer treatment plans today involve combinations of radiation, drugs and surgery, with surgical resection of the tumor occurring either before or after other types of therapies. Research has refined the delicate timing of these plans to optimize the interactions between different methods. Pre-surgery chemotherapy and/or radiation may make the tumor more effectively operable, or surgery may remove the most inaccessible parts of a tumor so that radiation and chemotherapy can destroy the rest. Recent advances in minimally invasive surgical techniques performed on the prostate, colon, esophagus and other organs have enabled a smoother transition between treatment methods, Matthews said. “Where technically possible, minimally invasive approaches are very successful in helping the patient recover faster from surgery,” Matthews said. “If the patient needs post-operative chemotherapy or radiation therapy, they’ll be able to start that process much more quickly.” Surgery also is useful in select cases of advanced cancer, where the tumor may have spread to sites beyond where it started. In colorectal cancer, for example, about half of patients develop liver metastases, 10 to 20 percent of whom are candidates for surgery. Of those patients who have their liver metastases resected, 25 to 30 percent will be long-term survivors. “With metastatic disease, it doesn’t mean that the surgeon is not involved,” said Mitchell Posner, MD, the Thomas D. Jones Professor and chief of the Section of General Surgery and Surgical Oncology. “We’ve always performed surgery on patients with advanced cancer. But new drugs are working better and reducing the size of tumors before surgery so that surgery is an option for an even greater number of patients.” Having experts specialized in surgical removal of tumors from particular organs and systems is of growing importance as cancer treatment becomes more individualized. In cases of liver cancer, whether surgery is an option frequently depends on how much of the organ must be removed. Michael Millis, MD, chief of the Section of Transplantation, and Giuliano Testa, MD, director of liver transplantation and hepatobiliary surgery, are well-known for their willingness to take on patients who have been turned down for surgery elsewhere. Mark Ferguson, MD, professor of surgery and a specialist in treating lung and thoracic cancers, and Marco Patti, MD, professor of surgery and the director of the Center for Esophageal Diseases, also show the value of having surgeons with experience in treating particular organs. “The really crucial element is having a team of experts who know the latest about radiation therapy, the latest about surgery and the latest about emerging protocols and how they fit together,” Matthews said. “You need an experienced team to know the right timing of when these treatments should be done.”
New Frontiers from Unexpected Places As the “big three” of traditional cancer treatment — radiation, drugs and surgery — are continuously revamped and improved, inventive new strategies also are being tested to thwart cancer. These methods draw upon the latest discoveries in fields such as engineering, the science of new materials, stem cell biology and computer science, bringing those advances into the medical arsenal against cancer. In collaboration with scientists at Argonne National Laboratory, Maciej Lesniak, MD, director of neurosurgical oncology and the Brain Tumor Center, has been looking for ways to use incredibly small nanoparticles as weapons against glioblastomas, an especially hard-to-treat cancer of the brain. The research is exploring multiple ways of using nanoparticles, small enough to fit 10 million inside a single centimeter, to attack tumor cells. In one experiment, the particles are attached to a photocatalyst and targeted to tumor cells. When exposed to light, the particles will release free radicals, molecules that are deadly to cells. Another strategy employs flat “microdiscs” that bind selectively to tumor cells and rotate when exposed to a magnetic field, literally stretching the cells to death. (See the breast imaging article on page 19.) “In some cancers, the brain or pancreatic cells are multiplying at such a rapid rate,” Lesniak said. “When you have a cancer that grows that rapidly, the prognosis can usually be measured in months or years at most. It’s always a battle between how quickly the cancer is growing and the available therapies. In this case, we are trying to actually damage the cancer cell in a mechanical fashion.” The laboratory of Ezra Cohen, MD, associate professor of medicine and an expert on squamous cell carcinoma of the head and neck (SCCHN), is testing nanoparticles as a therapeutic delivery mechanism. Cohen, in partnership with Argonne, has created nanoparticles that contain the chemotherapy drug cisplatin. When injected into a mouse model of SCCHN, the particles found their way to their tumors and released the drug, causing significant tumor regression. Bakhtiar Yamini, MD, assistant professor of surgery, is developing a similar drug-filled nanoparticle that can be used to treat brain tumors. Yamini’s laboratory also is developing new ways to transport those particles across the blood-brain barrier, allowing for easier administration.
Researchers in the relatively young field of molecular engineering also are offering new perspectives on fighting cancer away from the campus of the Medical Center. Milan Mrksich, PhD, Richard Schilsky, MD, chief of professor of chemistry, is studying how hematology/oncology at the the shape of cells affects their develop- Medical Center. Photo by Dan Dry ment and behavior. He proposes that migrating cells that lead to metastases take on a particular shape that can perhaps be prevented. Margaret Gardel, PhD, assistant professor of physics, is looking at cells as machines, with component parts that allow them to take shape and move — work at the border of cell biology and condensed matter physics. Such adventurous theories are likely to be at least several years from clinical trials and treatment therapies. But the recruitment of ideas and expertise from all corners of science is testament to the all-out search for treatments that will cure, or at least control, cancers in our lifetime. “One of the things that we do best is develop teams of investigators,” Le Beau said. “By bringing investigators together from multiple disciplines, we actually create a new discipline and create new science that addresses questions that would not otherwise be able to be studied.” Science is a gradual process. Every victory and advancement is accompanied by 10 times the amount of failure and frustration. But significant progress has been made from the first revolutionary but crude experiments with radiation and chemotherapy in Chicago to today’s broad spectrum of treatments that make more cancers vulnerable. “Instead of thinking too grandly — that we’re going to cure all advanced cancers — we should first think in terms of making metastatic cancer a chronic disease,” Geoffrey Greene said. “Then it becomes something you can live with.” Personalized genomics, computer-calibrated radiation therapy, advanced surgical options and biotechnology — all these innovations are both the present and the future in making cancer treatment dramatically safer and more effective. Surrounded from every side, cancer is being tamed, stripped of its deadliness and rendered manageable, if not cured.

normous strides have been made in treating cancer over the last several decades. But that success is conditional, with remission and cures seen in too small a percentage of cancer patients. As a result, the search for better cancer drug therapies remains intense. Researchers around the world are looking at nearly 1,000 different compounds, seeking drugs for cancers with no effective treatment or for patients who don’t respond to established therapies. More of those drugs are being tested clinically at the University of Chicago Medical Center than at any other center in the region. The Medical Center is one of the few programs in the country funded by the National Cancer Institute (NCI) to conduct hundreds of Phase-I, Phase-II and Phase-III trials. Many of these trials involve drugs currently under investigation at the Medical Center. “There are a zillion theories; that’s why we have so many investigational drugs,” said Mark J. Ratain, MD, the Leon O. Jacobson Professor of Medicine and director of the new Center for Personalized Therapeutics and the associate director for Clinical Sciences in the Comprehensive Care Center. Ratain directs the Phase-I program at the Medical Center. “One of these theories will be right one day. What we have to offer now is hope. Some patients actually get benefits, but everybody gets hope.” With treatments under investigation for virtually every type of cancer, the Medical Center frequently receives patients from other hospitals in the area, including other academic medical centers, Ratain said. For many of these patients, established treatments have failed to slow the progression of their disease, leading them to decide to take a chance on new drugs with unknown
benefits and consequences. “The patients are motivated to participate because of the potential for benefit in a setting where presumably there are no other alternatives that even offer that potential,” said Chris Daugherty, MD, professor of medicine and chair of the Medical Center’s Institutional Review Board. “Rather than take a standard therapy that you know will not work, it is justifiable to consider taking something where you don’t know if it will work and where there is good scientific judgment that says we know that this agent kills cancer cells in the laboratory, so there is a scientific rationale to justify testing in real patients with real tumors.” Daugherty’s research on the motivations and attitudes of participants in clinical trials is just one feature that makes the Medical Center a unique investigational entity. An NCIdesignated Cancer Center for nearly 40 years, the Medical Center can boast an experienced infrastructure for clinical trials, either originating from in-house research or from pharmaceutical companies needing to test out new drugs. Frequent communication between different medical disciplines and researchers at clinical and basic research levels also fosters innovative new ideas about treatments and how to test them. “In many ways, we’re big enough so that there is broad expertise in a wide variety of different areas,” said Walter Stadler, MD, Fred C. Buffett Professor of Medicine and director of the Medical Center’s Phase-II program, “but small enough that it’s easy to have these conversations between disciplines. The fact that the epidemiologists, basic scientists and clinicians are all relatively close is a good thing.”

One such multi-disciplinary interaction led to the Food and Drug Administration’s approval of one of the first drugs to treat advanced kidney cancer, sorafenib. This drug was originally developed to inhibit Raf, a protein involved in a variety of common cancers, including colorectal cancer. But Medical Center researchers convinced the sponsor to allow broader testing and observed a positive effect of the drug upon kidney tumors, leading to successful Phase-II and Phase-III trials overseen by Ratain and Stadler. Those clinical trials also employed new strategies created by Ratain to solve a recurring issue — how do you study the effectiveness of a drug that may only Ravi Salgia, MD, PhD, professor of medicine and director of the Chest Oncology and Thoracic Oncology be effective in a fraction of patients?

Our infrastructure allows us to test these various ideas process; it may only be the middle of it,” Odenike said. “This in patients.” research needs to be bi-directional for us to fully understand the mechanisms.” That philosophy is shared by Ravi Salgia, MD, PhD, professor of medicine and director of the Chest Oncology and Thoracic Oncology Research Program. “Many times people think of translational research as only bench to bedside, but we do the opposite too — we’re also bedside to bench,” Salgia said. Salgia’s research, which spans from testing the effects of cigarette smoke and gene mutations in microscopic worms to clinical studies of drugs that affect an over-active signaling pathway in lung cancer patients, reflects the smooth connection between laboratory and clinic that underlies Medical Center studies. Some of those same drugs are being tested in other trials on other types of cancers — head and neck cancer, mesotheliomas, neuroblastoma. Other innovative trials include Ezra Cohen’s research on the amplifying effect of grapefruit juice upon rapamycin, and Steven Chmura’s study of a drug derived from scorpion toxin used to treat brain tumors. “Right now, we tell many patients that we hope they can live a couple years longer,” Ratain said. “But we hope we can find drug therapy that’s going to keep patients alive indefinitely, Walter Stadler, MD, Fred C.

when I came here and that was huge. I had a chance. My other doctor was so negative. I wanted a doctor who involved me in the decisions.” Sibley’s course of treatment was a mastectomy, chemotherapy, radiation, then breast reconstruction with implants in both breasts. Because Sibley’s mother died after she was diagnosed with breast cancer at age 57, she wanted to make sure that doctors could learn as much as they could from her own situation and signed up to be a part of a succession of clinical trials. Sibley has a daughter and nieces and was concerned for their health as well. While some patients see clinical trials as a means to get access to better drugs or advanced treatment, Sibley says those factors were never her motivation: “If there’s any way to find out more about cancer, and I can help, I’ll do it. I did the clinical trials to give doctors more answers, not to help me.” Sibley’s first clinical trial was a randomized trial in which she was given extra cycles of standard chemotherapy to see if it would improve outcomes. Her second trial was a randomized Phase III trial that tested anti-estrogen therapies for early stage breast cancer. Her third trial added an estrogen therapy shot once a month to her ongoing treatment to see if adding an agent that targeted growth factors of hormone-sensitive cancers could slow down the spread of the disease by blocking estrogen pathways. The fourth study tracked markers in patients’ DNA to see if physicians could predict a better outcome based on genetics. Sibley’s current clinical trial is one run by Eileen Dolan, PhD, professor of medicine, in which researchers are studying whether they can predict toxicity or the effects of capecitabine, a standard chemotherapy drug, based on genetic markers. (See the mapping genes article on page 12.) “I’m so grateful that my niece got me here,” Sibley said. “I’ve told my daughter and nieces to all get tested.”

the standard treatment for all patients. Surgeons strive to make surgery as minimal as possible to lessen recovery time and make reconstruction easier. “Particularly for breast cancer and breast issues, there is no cookie-cutter plan,” said Nora Jaskowiak, MD, surgical director of the university’s Breast Center. “The vast majority of breast cancer patients are long-term survivors.” Women with certain kinds of tumors can benefit from pre-surgical chemotherapy because it can shrink their tumors significantly. This can mean avoiding a full mastectomy in favor of a lumpectomy, or a more localized lumpectomy that removes a smaller portion of the breast. For some women whose tumors appear inoperable, chemotherapy can shrink the tumor to the point where surgery is possible. About a quarter of Jaskowiak’s patients receive chemotherapy before surgery. In lumpectomies, the surgeons have found that it’s difficult to reconstruct the breast after a woman has had radiation. So the plastic surgeon is called in for consultation before the original surgery and then performs the reconstruction before radiation begins, which delivers much better results, Jaskowiak said. About a decade ago, David Song, MD, chief of plastic and reconstructive surgery, helped define the Medical Center’s perforator flap treatment, which uses fat on a woman’s abdomen while preserving muscle to reconstruct resected breasts. “These techniques help women regain confidence,” Song said. “The patient can even look better and more youthful than before her diagnosis.” Medical Center surgeons perform 200 perforator flap operations a year, more than any other hospital in the Midwest. The surgery takes upwards of six to eight hours per breast and can be done immediately following surgery to remove the cancer, if the patient doesn’t require radiation. As the dominant center in the Midwest for breast reconstruction, Medical Center plastic surgeons are leading the development of a new surgical field called oncoplastic surgery.

Getting a Clearer Picture of Breast Cancer By Cheryl L. Reed
nce a week, oncologists, surgeons, radiation oncologists, pathologists and radiologists all crowd into a conference room to view breast images on an 8-foot screen. It is the cornerstone of the University of Chicago Medical Center’s breast cancer program, where specialists outline what they believe is the best course of treatment for each patient. Their conclusions are based on repeated and careful examinations of MRIs, mammograms, CT scans and ultrasounds along with a pathologist’s report about the biology of a tumor. What few patients realize is that the precision of their doctors’ diagnoses is directly dependent on the quality of the diagnostic images. “Because we have more accurate images, it changes how we treat patients,” said Gillian Newstead, MD, clinical director for the Section of Breast Imaging at the Medical Center. “We have perfected MRI techniques here. We are able to show the extent of the cancer. Our whole tool box has become much larger. With our datasets, we are able to make diagnoses as well as prognoses.” By working with scientists, physicists and the companies that produce imaging technology, the Medical Center’s Section of Breast Imaging is able to combine the latest technology with sophisticated treatment and surgery to ensure that the full extent of a patient’s cancer is detected and removed. The Medical Center’s push to advance imaging is being funded by an $11.5 million National
Cancer Institute’s Specialized Programs of Research Excellence (SPORE) grant. Two of the grant’s four major projects focus on improving mammography and MRIs. One project concentrates on developing image-based markers to determine the risk of breast cancer. The other is looking for ways to use MRIs to find very small early cancers or precancerous lesions by correlating genetic and biologic markers found in tissue biopsies with findings from MRI scans. “What’s unique is that half of the SPORE grants are for taking standard images and analyzing the data further and coming up with new ways of imaging,” Newstead explained. “Our surgeons work very closely with us. Every time they have a cancer that can’t be felt, they come down, and we go over the images immediately before and during surgery, to be sure that the cancer is excised completely. That’s not the standard of care elsewhere.” MRIs, which give a more precise picture of tumors than mammograms or ultrasounds, have become an important tool to help doctors more accurately locate tumors in a woman’s breast. As part of another research study, high-risk women, such as those with a genetic predisposition for breast cancer or those who received radiation to their thorax as young adults, are screened with an MRI every six months for tumors as opposed to national recommendations to screen once a year. This helps catch tumors earlier, Newstead explained. Additionally, every woman diagnosed with breast cancer at the Medical Center is given what’s called a “staging MRI” to create a clearer picture of the known tumors and locate any smaller ones

that remain stubbornly hidden in other tests. The Medical Center was one of the first hospitals in the Midwest to offer staging MRIs to all diagnosed women, Newstead said. Physicians also can perform biopsies using MRI guidance, allowing them to accurately pinpoint the tumor for the test. Newstead said the next step will be to start treating women inside an MRI machine by aiming a High Intensity Focused Ultrasound (HIFU) beam at tumors to remove them. “We have been using it in animals, not humans yet,” Newstead said. “It’s the same kind of technique that they are using on brain tumors with mouse models. The holdup is with the FDA. It’s going to be another year or two, but we’ll be pioneering that effort here.” Last fall, the Section of Breast Imaging expanded its hours for screenings, even adding Saturday appointments. The additional scheduling increased mammogram patients initially by 20 percent. Breast Imaging also added digital imaging mammography machines to its screening department. The diagnostic department has used digital mammograms since 2002. Digital images are better at detecting cancer in younger women and women with dense breast tissue, Newstead said. Having digital images also makes it easier for patients to take their results to another physician if they want a second opinion. Despite a government panel last fall that suggested women with no family history of breast cancer not undergo annual mammography screenings until they are at least 50, physicians at the Section of Breast Imaging remain adamant that all women over the age of 40 should schedule mammograms once a year. If any imaging reveals a tumor, the patient is referred to a surgeon. “There’s overwhelming evidence that regular mammograms save lives,” Newstead said. “We don’t have anything else. We know we find small cancers through mammography. What are we going to do? Wait until they grow and they become palpable and the patient’s prognosis is worse?” Newstead and a team of other Medical Center physicians — Robert Schmidt, MD, professor of radiology; Hiroyuki Abe, MD, PhD, assistant professor of radiology; Charlene Sennett, MD, assistant professor of radiology; and Kirti Kulkarni, MD, assistant professor of radiology — are working with Philips, the company that makes MRI machines and the work stations to view them. The goal is to design a multi-media database and work station where physicians can view MRIs, ultrasounds and mammograms. That database also would catalogue all imaging, clinical and medical records.

“We are working not just with the equipment we have, but we’re working to develop new equipment and advanced integration techniques with the company,” Newstead explained. One thrust of research at the Medical Center is finding better ways to distinguish between aggressive and “innocent” cancers in patients who have Ductal Carcinoma In Situ (DCIS), an early cancer that has not spread beyond the milk duct. “We can’t differentiate between the good guys and the bad guys,” said Newstead. “We are over-treating a lot of women who have this kind of cancer.” The other focus of research is detecting cancer in lymph nodes. Newstead is collaborating with researchers in the university’s physics department to analyze the mathematics of cancerous tumors and their linkage to metastases in lymph nodes. The goal, she said, would be to allow less invasive treatment, perhaps ultimately avoiding surgery of lymph nodes in some cases. “There’s no such thing as a breast cancer,” Newstead said. “It’s very heterogeneous. There are multiple different types. Some of them are fairly good cancers. Some are horrible cancers. There is a huge range.” Susan Chandler and Emily Stone contributed to this report.

For Eric Whitaker, it’s personal. “I wrote on my application to Pritzker in 1986 that I wanted to become a doctor to improve health on the South Side,” he recalled. “This brings me back to where I started,” said Whitaker, MD, executive vice president for strategic affiliations and associate dean for communitybased research at the University of Chicago Medical Center. “It’s exciting to have the resources of this campus to work with the community to improve the health of the place where I grew up and am raising my family.” Under the Urban Health Initiative (UHI), Whitaker — who led the Illinois Department of Public Health from 2003 until joining the Medical Center in 2007 — is leading a multi-pronged effort to transform health in the community he calls home. The South Side is one of the nation’s largest medically underserved urban areas. Forty percent of residents are Medicaid recipients and 42 percent are uninsured, according to the city’s health department. It’s also the Medical Center’s primary service area and a place where the ills of a dysfunctional health care system are a daily reality. The 1.1 million population suffers disproportionately from diabetes, hypertension, asthma and other chronic, but preventable or treatable conditions — disparities compounded by widespread lack of insurance and a health care system that has been substantially less than the sum of its parts.

“|We can produce all the doctors we want, but if they all go to work on Michigan Avenue, we’re not having an impact.” — Eric Whitaker, MD Through UHI, the Medical Center is pursuing an ambitious program, pulling together experts from across the university, such as the Office of Civic Engagement and even across the Midway, such as the School of Social Service Administration. Local civic and church leaders also are helping to attack these glaring inequities from all sides. This starts with building a coordinated system of care. Under the South Side Healthcare Collaborative, the Medical Center has joined forces with 25 community health centers and five community hospitals to create a cohesive health care network. The effort cuts to the heart of the national health care debate and the all-important issue of access, said Whitaker. “We’re creating a system that ensures people not only have insurance, but access to care, too.” Central to this effort is connecting people to a primary care provider they can count on for prompt attention, checkups and screenings, management of chronic conditions, referrals to specialists and health education.
residents, 64 percent didn’t know community health centers existed, Whitaker said. “These facilities have typically not had resources for marketing,” he explained. “We’re letting people know about these gems.” Based in the Bernard Mitchell Hospital ER, Rebecca McNicholas and Vanessa Muhammad are key players in this effort. They are part of a cadre of eight “patient advocates” stationed in the ERs of Comer and Mitchell, under UHI, tasked with connecting people to a community medical provider. Typical emergency conditions seen at Mitchell include chest pain, abdominal pain and respiratory distress. And although the adult ER is not a trauma center, occasionally it treats gunshot wounds and other critical injuries. The facility also sees its share of patients with non-life threatening conditions — lacerations, abscesses, rashes, headaches and confusion over medication, for example — who are better served by a primary care provider with whom the patient can forge a long-term relationship. These are the people in whom McNicholas and Muhammad are interested.

The primary care provider model is gaining traction nationally. Studies have shown that improving access to primary care reduces hospitalization, particularly for chronic diseases, in urban areas. Within UHI, connecting people to a primary care provider is a key lever for shifting the focus from sporadic, reactive care to wellness and prevention. Lacking a stable health provider, many South Side residents currently turn to the Medical Center’s Emergency Department for care. Their immediate symptoms can be treated, but because the hospital is geared toward acute and complex care, underlying conditions may go unresolved and preventive services cannot be offered. The habit of visiting the ER for routine medical needs runs deep, ingrained by established folkways, observed Whitaker. “People have been socialized to come to the ER; we’re trying to change social norms.” This begins with raising awareness of alternatives such as federally qualified health centers. They are the “backbone of the safety net,” said Laura Derks, director of the South Side Healthcare Collaborative. Many of these centers provide services on a sliding-fee scale and offer the kinds of specialties, such as dentistry and nutrition counseling, that are simply unavailable in the ER. But the very people these centers are designed to serve are frequently unaware they exist. A survey in the fall of 2007 revealed that, out of 500 University of Chicago Medicine on the Midway
It’s late on a weekday afternoon, and the ER is filling up. The mood is calm but tense. McNicholas and Muhammad put the average wait-time for non-life-threatening cases at six to nine hours. “Is there anyone here without a primary care doctor who’d like to be set up with one?” Muhammad asks over the general hubbub. Five hands go up, and she speaks to each person to determine his or her needs. Denise Austin, 57, is in a wheelchair with chronic leg pain from falling recently at a South Side bus station where she’s a cleaner and attendant. Austin says she has no doctor because her job doesn’t provide health insurance. “The way it is, you have to have health insurance,” she says. Muhammad discusses several South Side Healthcare Collaborative sites where Austin can receive follow-up care after she’s been treated. Austin chooses ACCESS AuburnGresham Family Health Center, where she will be seen the following week. UHI has an arrangement with some South Side Healthcare Collaborative partners in which appointments are reserved as needed for patients referred from the Medical Center. The co-pay is approximately $45, but ACCESS operates on a need-based sliding scale if Austin can bring a pay stub. The records from Austin’s treatment in the ER will be faxed to ACCESS before her appointment. Muhammad also does the rounds of patients in the examination rooms. She treads carefully amid the whirl of activity, parting the curtains that screen patients to snatch time with them. Trying to catch those who might fall through the cracks, Muhammad will later call patients who left the ER without being seen to discuss if they can be connected with a medical home. McNicholas, who also works the phones, says she reminds patients of upcoming appointments at South Side Healthcare Collaborative sites and checks in afterward to find out how appointments went. She’s not afraid to cajole when someone misses an appointment and has to reschedule. “I say, ‘promise me you’ll go.’” Visiting federally qualified health centers can be revelatory, noted Whitaker, whose own family receives care at a community health center. “When people see them, they’re like, ‘wow, this is nice.’”

This could describe someone’s reaction on visiting Chicago Family Health Center in South Chicago. The facility includes 30 examination rooms, a dispensing pharmacy, a 75-person waiting room with six patient registration bays and a dental clinic. In 2008, UHI funded a new women’s health wing. Like other health centers, it offers a comprehensive menu of services that “wrap around” medical care, including a nutritionist for dietary advice, financial counselors to assess eligibility for public assistance, case workers to help navigate the system, a social worker and a clinically-licensed psychologist. For “working poor” patients, for whom time out of work represents forfeited income, this collection of services provides an invaluable one-stop shop, said CEO Warren Brodine. Treating non-critical patients in such settings also meshes with the economics governing health care — a key consideration amid a wave of hospital closures, locally and nationally. The overheads of education, research and equipmentintensive advanced care means it costs the Medical Center’s ER $1,200 to deliver the same primary care a health center can provide for $120. Meanwhile, the government provides incentives to federally qualified health centers to offer primary care services to low-income patients, allotting a typical reimbursement of $120 for primary care services rendered to Medicaid patients versus the $35 the Medical Center receives on average for delivering equivalent services. The federal government underwrites community health centers because they focus on serving low-income and uninsured populations. Building a robust health care system also means addressing a growing shortfall of primary care physicians — projected by the National Association of Community Health Centers to balloon to 40,000 by 2035. “It’s a big problem,” observed Whitaker. “We can produce all the doctors we want, but if they all go to work on Michigan Avenue, we’re not having an impact.” Another key UHI goal is to inspire Pritzker students to pursue careers in primary care and community medicine.

director of Community Health and Service-Learning. “I want students to see how satisfying a career in the community can be,” she said. Schumann, MD, presides over several programs that train students in community medicine. Students can enroll in a community health track within the new Pritzker curriculum. Graduates committing to practice on the South Side can apply, through the REACH Program, for financial breaks of $40,000 a year (up to a maximum of $160,000 over four years) to defray their student debt — a boon for Pritzker alumni who graduate on average with more than $200,000 in debt. Schumann works closely with the forthcoming Center for Community Health and Vitality, a key organization within UHI charged with tackling the socioeconomic and environmental determinants of health. “Improving health is not just about what doctor you see,” explained Center Director Doriane Miller, MD. “There are multiple factors, including proper nutrition, community safety and healthy behaviors.” Besides administering the South Side Health and Vitality Studies (see accompanying article), the Center will be the seat of a range of programs designed to connect people to essential services, jump-start grassroots initiatives, provide health education and train local youth for health care careers. Another critical function is ensuring the community is heard loud and clear within UHI. “This is a departure for the Medical Center,” Whitaker noted. “Historically, we’ve been focused on this campus.” UHI doesn’t just require a shift in the way the Medical Center relates to its community, he added; it demands that the Medical Center recast how it views itself. “If Medical Center physicians have a practice at Mercy Hospital, is that still seen as part of the University of Chicago? Previously, the answer would have been, ‘No, the University of Chicago is just the campus,’ ” he observed. “The new view is that we have a satellite branch where our faculty can see patients and teach.” The effort is being closely watched by other academic medical centers, some 70 percent of which are situated in communities with similar health indices, Whitaker said. He and others hope UHI also can become a model for urban health nationwide.

health issues of South Side residents — issues that were ranked as the most pressing among community leaders. “People talk about food deserts on the South Side, but there are health care provider deserts too,” explained Schneider. “Part of the secondary objectives of this pilot study is to ask the greater questions about residents’ access to health care. A lot of people are telling us that they don’t know where to go to see a dentist or to get HIV care.” The hope is that the long-term study will be able to establish a baseline picture of health for South Side residents which, in turn, will inform specific programs to target those health problems down to the neighborhood or even block. The studies would track the efficiency of health programs and how well they are addressing problems. Information collected would be used to attract federal and state funds by documenting the needs of the community. Funding for the South Side Studies, though, remains an obstacle. Because of its breadth and depth, the longitudinal study is estimated to cost anywhere from $8 million to $15 million, turning researchers into salesmen as they try to convince major donors, government entities and foundations to support the project. “We need to find philanthropists who are passionate about this issue,” explained Stacy Tessler Lindau, MD, assistant professor of obstetrics and gynecology and principal investigator for the South Side Studies. “Those sources of support are going to be very important in securing funding from the federal government.” Currently, the Resource and Retention pilot study and another pilot study last summer that mapped every nonresidential building in six South Side neighborhoods have cost the university about $200,000, not including faculty and staff time and overhead expenses. The Medical Center has committed an initial $1.5 million for development of the pilot studies, which includes building community partnerships and fundraising to extend the mapping project to all 34 South Side neighborhoods.

“One of the survey questions asks how likely they would be to do the study if we paid them $100 each time we talked to them. They just look at you and laugh and say: ‘Uh, very likely.’” — Jeff Bean, Field Researcher Mapping neighborhoods This past summer, Bean and Johnson were both field researchers in the mapping project that plotted everything but homes in six neighborhoods: Hyde Park, Kenwood, Woodlawn, Washington Park, Grand Boulevard and Eastside. That pilot study, called the Resource Mapping Project, was completed by summer’s end and the results were made available online in mid-October at www.southsidehealth.org. Visitors to the site can conduct precise searches of everything from car repair shops to health care clinics on the neighborhood level. Although researchers are still fine-tuning the website and aspire to extend the project to include all 34 South Side neighborhoods, the data was made available to the public before it was picture-perfect — part of the Medical Center’s promise to community leaders to share findings quickly and to solicit feedback on how to tailor data for community use. “We have definitely heard people say: ‘We’re tired of researchers parachuting in and doing studies and never getting information back,’” explained Lindau. “We’re doing things differently now. We’re working with the community and putting our joint product out in an early phase. This gives community and university folks a chance to work with the data, tell us how they want to use it, and then we work together to ensure it translates.” The information gathered in Woodlawn has already been handed over to community leaders like Arthur M.

bishop emeritus of the neighborhood’s mega church, Apostolic Church of God. Brazier has been working to revamp Woodlawn’s elementary school curricula to stress parent-teacher engagement and push the importance of college, starting from pre-school. Brazier is hoping the information from the mapping project will help make the case for a $25 million grant from the U.S. Department of Education that would enable them to change the curricula. Part of the Medical Center’s motivation behind the mapping project was to prove to community members that the university could be an equal partner and would live up to its stated commitments. At the mapping website’s unveiling, dozens of community members packed into the DuSable Museum of African American History, near the Medical Center’s campus, to give their unbridled input. Some openly admitted they’d been skeptical in the beginning, but the project had helped them warm to partnering with the university. “I was born and raised on the South Side and have a healthy skepticism about the university,” said Shirley Fleming, a member of the health ministry at Trinity United Church of Christ, also on the South Side. “We want to contribute to the process and to promote health in our community. This data allows us to apply for grants and be on the ground level. Let’s just say it’s made me hopeful.”
s if beating cancer wasn’t enough, cancer survivors face an even greater risk for health problems, such as heart disease, infertility, sexual dysfunction, depression, substance abuse, suicide, lack of insurability, pulmonary disease, anxiety and poor continuity of care. Add to that the risk of developing a second cancer, and you have a recipe for serious problems and stress, all of which are magnified if you are financially disadvantaged. Secondary stresses, apart from surviving cancer, are becoming more apparent as more cancer patients live longer. There are about 14 million people living in the United States who have been previously diagnosed with cancer, according to the National Cancer Institute. A 2009 study in the Journal of Clinical Oncology showed that about 80 percent of children will survive at least five years after diagnosis. “In pediatric cancer, we’ve had tremendous success in the cure rate. But as the population of survivors grows, they have significant long-term health issues, which can be attributed to their cancer therapies,” said Tara Henderson, MD, director of the Medical Center’s Childhood Cancer Survivors Center. “As patients are transitioned to survivorship, we have to consider their health throughout the remainder of their lives. Now, our focus in pediatric oncology is on minimizing the long-term morbidities from the very beginning while still maintaining or improving our cure rates.” Each age group of cancer survivors faces different issues. Elders often struggle with hypertension and lack of social support, while adults often struggle with infertility, employment-related problems and marital and family issues. Children are especially vulnerable because some treatments harm their developing bodies. In 1997, 6-year-old Elizabeth Noreen of Palos Hills, Ill., was diagnosed with a primitive neural ectodermal tumor, a rare cancer with a survival rate of less than 40 percent. Worse yet, the cancer was Stage IV and had metastasized to the lungs.
Spending most of the next eight months at Comer Children’s Hospital at the University of Chicago, Elizabeth received radiation therapy, chemotherapy and a stem cell transplant. Now, at age 18 and long-since cancer free, Elizabeth has to deal with a host of issues related to her cancer treatment. Because of all the radiation, she has a lung capacity of 50 percent, which has led to multiple lung infections. She has thyroid problems and will not be able to conceive. And she has missed so much school that her test scores and academics are below par. Meanwhile, transitioning from pediatric to adult caregivers is proving to be difficult. “This has been tough, but with good family and friends and the top-notch care, we pulled through,” said Denise Wysocki, Elizabeth’s mother. “Still, the issues never seem to end.” Nevertheless, Elizabeth has demonstrated strong resolve. “First, you have to stick with your treatments even if they say you have a good chance of dying,” she said. “Then, you have to keep trying to cope with everything else that comes along and stay positive.” Elizabeth is so positive that she wants to become a clinical care specialist and take care of kids at Comer Children’s Hospital. She and her mother appreciate the well-rounded care they received at the Medical Center, where providers are very attuned to the special needs of patients who survive childhood cancers. “Cancer therapies can impact just about any organ you can think of,” Henderson said. “We administer toxic drugs and radiation to growing organs. Survivors are not aware of their risks, and need screening and follow-up care. It’s no surprise that mortality and morbidity are high for childhood cancer survivors.” A striking example of this is the fact that approximately 20 percent of females who survive childhood cancer and have received chest radiation as girls develop breast cancer by the age of 45, compared to about 1 percent in the general population, Henderson said.

To address such problems, the Medical Center conducts research and offers cancer survivors counseling and support groups. The Psycho-oncology Service offers evaluation, consultation and therapy for adult cancer patients, collaborating with oncologists, social workers, chaplains and nurse practitioners. Last year, the Medical Center joined the Childhood Cancer Survivorship Study, the largest, most comprehensive cohort study of childhood cancer survivors in North America. This

study was initiated in 1993 with a grant from the National Cancer Institute and is coordinated through the St. Jude Children’s Research Hospital. It allows investigation of treatment and follow-up data for 14,000 patients diagnosed with cancer from 1970 to 1986 at 30 medical institutions in the United States and Canada. Medical Center research builds on this and other studies. For example, in an effort to reduce the incidence of breast cancer in survivors, Henderson is trying to identify which children with Hodgkin’s Disease should forgo radiation therapy. Also, she is studying how awareness of late effects of cancer therapy and second cancers impact outcomes. “We’re discovering that many cancer survivors don’t know they’re under increased risk,” Henderson said. “New research that we’ll publish soon reveals even pediatric oncologists are unaware of these risks.” This lack of physician awareness may be alleviated because internists and pediatricians are developing subspecialties in cancer survivorship, noted Michelle Le Beau, PhD, director of the University of Chicago Comprehensive Cancer Center. “Our overall goal at the Medical Center is to provide comprehensive care: diagnosis and treatment, support and survivorship,” she said. Cancer survivors and their caregivers — in addition to being vigilant about medical issues — must deal with psychosocial effects, such as emotional, spiritual and economic challenges. “We need to help cancer survivors achieve and maintain a good quality of life,” said Amy Siston, PhD, clinical associate in psychiatry and behavioral neuroscience. “Patients may complete their cancer treatment, but there are physical and psychosocial issues, such as depression, anxiety and fear of reoccurrence, that patients deal with many years later.” 30 University of Chicago Medicine on the Midway
After Niki, a 33-year-old Chicago woman living in Las Vegas, found out she carried the BRCA1 genetic mutation, which increases her risk of breast and ovarian cancer, she took extraordinary precautions to prevent getting cancer. She has had blood tests and a transvaginal and pelvic ultrasound twice a year for the past seven years. She even had a double mastectomy. “I work out a lot and was getting screened twice a year through ultrasounds and blood work for ovarian cancer, so I thought I was doing a good job staying on top of everything,” said Niki. One day in May 2009, Niki’s blood work showed the possibility that there was a presence of cancer in her body, so the next day she had a CT scan. It revealed a large mass in her abdomen. Niki immediately moved from Las Vegas back to her native hometown, Chicago, where Diane Yamada, MD, chief of the Section of Gynecologic Oncology, agreed to do emergency surgery. Yamada found that Niki had primary peritoneal cancer, which is quite rare. The cancer was advanced — Stage IV — with tumors on several of her organs. The median survival for patients in her condition is five years. After surgery, Niki had six cycles of aggressive chemotherapy. “I’d like to tell other women, especially those with BRCA1 genetic mutation, that today’s screening tools are not adequate,” Niki said. “I hope doctors and researchers are developing better screening tools.” To help cope, Niki remembers a lesson she learned from her father, who died of pancreatic cancer last summer: Live every day to the fullest. Niki credits Siston, her counselor, for helping her to keep such a positive attitude. “I see her weekly, and she has been amazing,” she said. “Amy has helped me realize that there are things worse than dying — like dying without having lived.”

ennifer Sowacke had been trying for two years after the birth of her second child to get pregnant. The day she discovered she was five weeks pregnant, she also felt a lump in her breast. It was too early in the pregnancy to safely have a mammogram, and her doctor told her not to worry about the lump. She pressed him for a biopsy. It showed that she had a malignant tumor. She immediately saw a surgeon, but he refused to treat her. “He wouldn’t touch me until I terminated the pregnancy,” she said. Devastated, Sowacke made an appointment for a second opinion at the University of Chicago Medical Center at the suggestion of a neighbor. She met Nora Jaskowiak, MD, the surgical director of the Breast Center. Jaskowiak told her that it would be harder to treat her while pregnant, but it wasn’t impossible. Sowacke and her husband, Paul, decided to keep the baby. “She was going to have to treat it as a patient within a patient,” said Sowacke, of Homewood, Ill., who was 32 at the time with no history of breast cancer in her family. “I knew they were going to treat me with the baby in mind, and that was very important to us.” The next eight months were an emotional mix of fear of the cancer and what the treatment might be doing to her fetus, and excitement about having a new baby. “It was something so good going on while something so evil was going on,” Sowacke said of the ordeal she went through seven years ago.
Tara Henderson, MD, director of the Medical Center’s Childhood Cancer Survivors Center, says chilhood cancer survivors are often not aware of the risks of toxic drugs that show up later in life.

Sowacke, now 39, remembers Jaskowiak walking her and her husband through the treatment options and explaining the added complications the pregnancy presented. For example, she had to wait until she was 11 weeks pregnant to have a mastectomy because it’s dangerous for a fetus to undergo anesthesia earlier than that. Sowacke could only be safely anesthetized for five hours, so Jaskowiak had to remove one breast and all the attached lymph nodes within that deadline. Sowacke needed to have a mastectomy because she could not receive radiation while pregnant. In addition, her tumor was estrogen sensitive so anti-estrogen medication played a big role in her treatment. Jaskowiak said that Medical Center physicians treat about two pregnant women a year for breast cancer. Jaskowiak, who was also pregnant at the time, said Sowacke was the first such patient she had ever had. “My pregnancy gave me a deep connection to Jen and her family and their very strong desire to save the pregnancy,” Jaskowiak said. “There is no doubt that there is a special bond between us.” Jaskowiak listened to the Sowackes explain their desire to keep their baby and began planning Sowacke’s treatment. “We said, ‘OK, if this is one of your goals to preserve the pregnancy, it can happen,’” Jaskowiak said. The mastectomy went well, and there didn’t seem to be any harm done to the fetus. Sowacke’s test results came back clean, meaning Jaskowiak had removed all the cancerous cells. Sowacke waited to have chemotherapy until after the baby was born. So the rest of the pregnancy was a waiting game of trying to keep her spirits up and put on a brave face for her other two daughters, Abbey, then 4, and Grace, then 2. “There were times I cried,” Sowacke said. “But, every time I started crying or felt bad, I would feel that baby kick. It was almost like she was telling me to knock it off. I never felt alone.” In March 2003, Sowacke delivered a healthy little girl, Olivia. She started chemotherapy three weeks later and has been cancer free ever since. Olivia likes to hear the story about how Jaskowiak saved her and her mom’s life, and she always asks to go with her mom for checkups. “It’s been a thrill to watch her grow up,” Jaskowiak said. Sowacke is eternally grateful to Jaskowiak and the other doctors at the Medical Center who refused to give up on her baby. “If I hadn’t gone to the University of Chicago,” she said, “if I had stayed at my local hospital, my story would be totally different.”

Just when it seemed the project might be sidelined, Slamon’s phone rang. It was Lilly Tartikoff, a prominent LA figure and anti-cancer activist with an eye for promising developments. The question for Slamon and coworkers was, “why?” Translational medicine — recognizing the two-way street between knowledge gained directly from working with patients and scientific findings emerging from the labs — has become well established since the 1970s, when the approach was being pioneered by Rowley, professor of molecular genetics and cell biology. Bringing together clinical experience with laboratory knowledge encouraged researchers to see that something had to be going on at the molecular level to explain the divergence in clinical outcomes. “There must be biology there,” Slamon said, recalling the fundamental insight. “It was understanding that there must be molecular diversity that caused the field to take a quantum leap forward.” The insight can be traced to one of Rowley’s early findings. Using ordinary scissors to snip apart photographs of abnormal cells from leukemia patients, she was able to demonstrate in 1972 that bits of separate chromosomes had broken off and

Dennis Slamon makes a quiet impression. Especially for a famous Los Angeles physician whose work was featured recently in a film backed by major Hollywood star power. Slamon owes his fame to the lead role he played developing the drug Herceptin, a revolutionary treatment approved in 1998 for a common type of breast cancer. Sharing the credit seems to come naturally to the doctor. Among those he lists as contributors to the breakthrough development are research collaborators over the years and his advisors at the University of Chicago, where he earned PhD and MD degrees in 1974 and 1975. But Slamon reserves special mention for breast cancer patients themselves, women who agreed to take part in the early clinical trials leading to the Food and Drug Administration’s approval for the effective new drug. A professor of medicine and director, since 1988, of Clinical/ Translational Research at UCLA’s Jonsson Comprehensive Cancer Center, Slamon appreciates Southern California as a fine place to pursue his work. But Los Angeles has never replaced Chicago in his affections. The product of small-town life in western Pennsylvania, Slamon remembers Chicago as his eye-opening introduction to life in the big city. “It was a great time in my life,” he recalled. “Chicago was just a great city, with all the things a big city has to offer. But it had a blue-collar feel, with friendly people, and it worked very well for me.” Clearly a good match for the modest, determined, hard-working personal style for which Slamon has been noted throughout his career. Whatever the benefits of living in a major urban center, the real payoff for all concerned was the postgraduate training Slamon received at the University of Chicago. Exposure to the excellent faculty — Slamon recalled Janet Rowley, MD, Winston Anderson, MD, and Werner Kirsten, MD, in particular — was “more than educational. It was formative.” Working in Kirsten’s 32 For more information, call 1-888-UCH-0200 or visit uchospitals.edu
lab, Slamon helped identify an early example of the so-called oncogenes, or cancer-causing genes, which can be shown in experiments to be associated with malignancies. It was an “incredibly rich and robust environment for training people like myself, who would be armed to come at the problem from both sides of the fence.” The problem, in a nutshell, was the discrepancy between the apparent promise of chemotherapies based on new experimental findings in the laboratory, and the radically divergent patient outcomes being seen in the clinical setting of a hospital. “The one thing that kicked the whole process off,” said Slamon, “was that we had been using one-size-fits-all approaches.” The chemotherapy cocktails designed on the basis of lab experiments were being administered to patients based largely on where the cancer arose, in the lung, say, or in the breast. “What should have told us something was off was that the clinical outcomes were different,” he said. “Some people did incredibly well. Some people did incredibly poorly.”

exchanged places. It was because of this translocation of partial chromosomes that normal genes turned into oncogenes. In their original location they had regulated cell division and growth. Now they were causing normal cells to become cancerous. This was the initial discovery of the link between cancer and genetic abnormalities, for which Rowley was awarded the Presidential Medal of Freedom in August 2009. Given the relatively primitive technology available to Rowley at the time, Slamon marvels at her accomplishment. Productive findings can be hard to come by even today, using sophisticated computer software to compare huge panels of cancer cell lines in an attempt to link observed abnormalities to the underlying genetic constitution of the cell. But the results are unambiguous. Just because cancers originate in the same organ does not mean they are alike. Biologically speaking, some breast cancers are more like ovarian cancers, some lung cancers more like sarcomas. How a malignancy develops in the clinical setting — and thus what kind of intervention might be developed to stop it and save a patient’s life — depends not on the affected organ but on the molecular makeup of the disease. Herceptin, the drug developed based on Slamon’s preclinical and clinical research, targets a genetic abnormality that appears in about 20 to 25 percent of breast cancers, affecting more than 200,000 women each year worldwide. In these cases the HER2 gene, once again a gene that in normal cells
regulates division and growth, appears in abnormal cells in too many copies, resulting in overly rapid growth and a cancerous tumor. Herceptin works by inactivating a protein produced by the HER2 gene, which triggers the excessive growth. Used in combination with chemotherapy, the drug has transformed a very aggressive form of breast cancer, for which little effective treatment had been available, into a highly treatable disease. Some patients seem to overcome the malignancy altogether, living cancer-free years later, while in others the progress of the cancer is significantly slowed. Taking advantage of the conceptual breakthrough afforded by a translational approach was one thing; generating the level of funding necessary to turn the idea into a treatment is quite another. This is where the Hollywood connection comes in. By 1989, Slamon and his team found themselves at a crossroads, armed with promising new data but encountering resistance from funding sources in government and industry. “We tried to explain to them that we were targeting not just the marker of tumor cells but something that was playing a role in causing the tumor cell behavior,” he said. “But even with all the data, there were lots of naysayers.” Just when it seemed the project might be sidelined, Slamon’s phone rang. It was Lilly Tartikoff, a prominent LA figure and anti-cancer activist with an eye for promising developments. Of course, it didn’t hurt that since 1982 Slamon had been successfully treating Tartikoff ’s husband, the television producer Brandon Tartikoff, for a recurrence of Hodgkin’s disease. (Tartikoff died in 1997.) Lilly Tartikoff turned to Ronald Perelman of Revlon, persuading him to set up an unusual donor arrangement in 1990 that helped put Slamon’s research over the top and continues funding cancer research to this day. It was not just having celebrity backers that led eventually to “Living Proof,” the 2008 film about Slamon and his groundbreaking work. The story itself — determined scientist perseveres in the face of powerful resistance, succeeding against long odds in the nick of time to save an innocent life — is the stuff of a screenwriter’s dreams. With Harry Connick Jr., in the lead as the indefatigable Slamon and Bernadette Peters as Barbara Bradfield, the first woman whose life was saved by Herceptin, the film was guaranteed to attract some favorable attention. But, it also benefitted from an all-star cast behind the scenes, including Renée Zellweger as executive producer. The early funding difficulties, in Slamon’s judgment, delayed medical progress by as much as five to seven years. But, there is no doubt in his mind about Herceptin representing a paradigm shift in cancer treatment. With similar promising drugs already in use, and new ones in the pipeline targeting lung, prostate and other cancers, Slamon is confident that the future of this kind of research is secure. He foresees fundamental changes in the way a number of cancers will be treated just within the next four or five years. If he is right, and the success of Herceptin is matched for other malignancies, it will come, for a great many people the world over, as very good news indeed. Spring/Summer 2010 33
Finding a Compatible Match for a Gift of Life By Rob Mitchum
An organ transplant is a priceless gift that can save a person’s life. But the body is notoriously ungracious and has picky tastes that need to be satisfied with close compatibility or tricked by suppressing the immune system. As such, the actual transplant is the culmination of months of meticulous laboratory testing to create the right match between donor and recipient. At the University of Chicago Medical Center, that matchadult leukemias and lymphomas, require more selective donormaking process happens in one lab where the most advanced recipient matching and demonstrate the advantages of having the tests of today — and potentially tomorrow — are applied to each most powerful testing technology on site.

or Daniel Sulmasy, it was a life-changing moment. While Sulmasy, then a fourth-year medical student, was standing nearby in a patient’s hospital room, a brusque neurologist delivered the devastating news to the patient: “Lady, you have a big, fat tumor on your spinal cord. We’re going to have to give you radiation so you don’t end up paralyzed.” The physician and his white-coated entourage swept out of the room, leaving Sulmasy to comfort the weeping patient. That’s when he decided that medical ethics would be his calling. Today, Sulmasy, MD, PhD, is a 53-year-old internist and nationally recognized expert on spirituality and clinical care. He joined the Medical Center faculty in July 2009 after being recruited to fill a newly endowed chair in the MacLean Center for Clinical Medical Ethics by its founder and current director, Mark Siegler, MD. In April, Sulmasy was named to the Presidential Commission for the Study of Bioethical Issues. The Commission advises the President on policies and practices regarding advances in biomedicine and related areas of science and technology.
Most physicians wear more than one hat, but few don as many as Sulmasy. He is supervising interns who are treating outpatients at the Duchossois Center for Advanced Medicine (DCAM). He is teaching ethics classes and researching the overlap between medicine and religion. He is available at any hour for emergency consults about delicate end-of-life issues. And when he goes home at night, Sulmasy heads to a friary where he is a Franciscan brother. “A friar is who I am. What I do is medicine and ethics,” he explained during an interview in a book-filled office in the Medical Center’s Bernard Mitchell Hospital. If Sulmasy’s schedule weren’t full enough already, he plans to start practicing internal medicine with the Faculty Practice Group at DCAM in the coming months. In his previous life in New York, Sulmasy handled a patient load of about 250 at St. Vincent’s Hospital and New York Medical College in addition to his other duties. These days he is looking forward to being part of the Medical Center’s Urban Health Initiative, which he considers a moral imperative.
“People of reason and goodwill can agree that it makes good sense for a world-class medical center to share its knowledge and talent with the community around it,” Sulmasy said. There is no shortage of ethical issues in medicine to keep Sulmasy busy. “The technology keeps creating them,” he pointed out. One recurring question concerns whether it is morally permissible to give a dying patient a powerful pain medication like morphine even if the drug might hasten death. He comes down on the side of “yes,” and his philosophical argument is based on something called the “rule of double effect,” which states that if a person only intends a good outcome and certain other conditions are met, the action is permissible. “Dose does matter,” Sulmasy said. “But from a moral point of view, the dose should be given with the right intention.” Many of the questions Sulmasy tackles aren’t theoretical. He has conducted research with patients and family members about how accurately loved ones are able to use “substituted judgment” about end-of-life issues for relatives who can no longer speak for themselves.

The Man of Many Coats: Daniel ulmasy By Susan Chandler
The law says that when a patient is beyond being able to communicate his or her wishes, family members should do their best to proceed with what the patient would want. Sulmasy looked at patients with either cancer or Lou Gehrig’s disease and asked them how they would want to be treated at the end of life. Then he asked family members the same question. The family members got it right only 67 percent of the time. “That’s statistically significant, but it isn’t great,” he said. Even if there were a way to get that number higher, that might not be the best answer. Only 25 percent of patients surveyed wanted family members to make decisions solely based on the patient’s own personal preferences. Another 20 percent wanted family members to make the decision for them while 55 percent wanted a mix. Sulmasy takes seriously the burden that society and the medical profession place on family members when they are asked to make end-of-life decisions. “Bioethics pays most attention to the patient. Loved ones, however, are usually the ones being asked to make decisions about life-sustaining treatments, and they are under as much stress as someone whose house has burned down,” he said. “We’re urging people to discuss not just what they want now but who they want to make decisions. It’s as much about process as content.”
“A friar is who I am. What I do is medicine and ethics.” The process that brought Sulmasy to this point involved nearly two decades of education and religious training. He decided to join the Franciscans after his internship and spent two years contemplating his vocation during a “formation process.” Then he returned to finish his residency at Johns Hopkins in Baltimore, where he ended up as chief resident. He later added a PhD in philosophy from Georgetown University, finishing his education at the age of 39. Initially, Sulmasy thought he wanted to become a priest but later decided that being a non-ordained brother who engaged in works of service was the best path for him. As a member of a Franciscan community, Sulmasy is bound by the order’s vows of poverty, chastity and obedience. His salary goes to the order, and he receives a stipend to cover everyday expenses. Having a member of a religious community teaching and consulting on ethical issues at a secular medical school may seem an odd juxtaposition. Sulmasy acknowledges that he agrees with the Catholic Church’s position on many questions. But church doctrine is not the only guide to his thinking, and he sees no conflict between his position as a Franciscan and an ethicist. “We always ask ‘What is the right and good healing act for this patient in this particular circumstance?’ We answer that, and then we consider any legal constraints. Most of the time, the law allows us to do the right thing,” he said. “My position on most issues will be consistent with the church, but most of my positions are largely based on secular arguments. My degree is in philosophical ethics, not theological.”

Providing Hope and Love Through Adoption
International Adoption Clinic Assists in Promoting Health of Children
By Katie Scarlett Brandt
By Katie Scarlett Brandt
ne afternoon, pediatrician Larry Gray, MD, picked up his phone and dialed the number of a man in Michigan whom he had never met to discuss a little boy in China whom neither of them had ever seen. The man in Michigan and his wife wanted to adopt the Chinese boy and had sent Gray, who heads the International Adoption Clinic at Comer Children’s Hospital at the University of Chicago, the boy’s medical information from the Chinese orphanage. Gray started the Clinic in 2002, after approaching then-Chairman of Pediatrics Herb Abelson, MD, and explaining his vision. He wanted to assist parents before and after they adopted. And he wanted to help families by connecting them to specialists within the Medical Center, similar to how the Medical Center’s Comprehensive Cancer Above: Linda Walsh, RN, and Larry Gray, MD, talk with parents Donna and Center operates. “We’re trying to Steve Tucker about the latest additions to the Tucker family: Katherine, 2, help these kids get off to a good and Emily, 3.

But the Clinic offers some relief from that complex work, and her compassion for the families is obvious. “These families have just been through the big ordeal of bringing a crying kid home on a trans-Atlantic flight. They’re vulnerable,” she said. Three and a half years ago, Sandra Spadoni and her husband Dan Krebs, as featured in our fall issue of Medicine on the Midway, became one of those families. They were in Zambia conducting HIV research and volunteering in an orphanage when they decided to adopt their first child. For the remainder of their trip, they split their time between research and raising the newest member of their family, infant Josephine. Now in Chicago, Spadoni serves as assistant director for programming in the International Student Adviser Office at the university, and Krebs is a Pritzker School of Medicine student. Last year, they brought home a second adopted child. “We wanted to make sure that Josie had another member of our family who looked like her, who was from the same continent,” Spadoni said. As part of their home evaluation before the second adoption, Spadoni and Krebs had to supply a list of resources. In composing the list, they learned about the International Adoption Clinic. “Everything was very streamlined,” Spadoni said of their first experiences with the Clinic. “Not only did they take tons of time with us, but they really hooked us up with other services. They were so familiar with the issues of international adoption, with all the bugs that these kids can bring home.” According to Walsh, everything comes down to faith — faith in the children, faith that the parents can make a difference and faith that with a strong medical team in place, everything will work out. “This is the forefront of medicine,” Gray added. “We bring this high level medical care and technology to where the parents are. And these parents are pushing the envelope because they’re going to the far ends of the earth to adopt a child with HIV, and (overnight) they end up in a Chicago suburb because modern technology allows it — the airplanes, the Internet, the medicine. It’s just wonderful.”

Parents of 13, Carolyn and Kiel Twietmeyer first used the Medical Center’s International Adoption Clinic two years ago when they adopted three siblings from Ethiopia. Since then, Carolyn and Kiel founded a not-for-profit organization called Project Hopeful that partners with Medical Center physicians to educate families who want to adopt children with HIV or AIDS. “HIV is a lot more manageable now,” Carolyn said, attributing the evolution to new medications and technological advancements. “People assume it’s still the tragedy it was in the ’80s and ’90s, but it’s not.” Carolyn has made advocating for these children her life’s work. In the past two years, she also has partnered with lawyers in Washington, D.C., and successfully lessened the restrictions on bringing children with autoimmune diseases into the country. She rattled off government statistics that support her efforts: eight HIV adoptions in 2007 and 150 in 2009. “These are kids who absolutely had no chance for a long life,” Carolyn said. She traces her passion back to her childhood. At age 6, she watched an Ethiopian drought unfold on the local news. Why, she wondered, were people there starving and living in the streets when the people closest to her lived in homes with spare bedrooms and pantries full of food? “It was a very simple thought process, but it’s still how I think,” she said. Currently, Carolyn, who home schools her children, and Kiel, a construction worker, have seven biological children, ranging in age from 3 to 19. Two years ago, they decided to adopt a sibling group of three from Ethiopia. The middle child of the three, Sam, had HIV. The orphanage where the children lived had been trying to split the siblings in order to give the other two children, Rachel and baby Seth, a better chance of being adopted. The Twietmeyers refused to tear the children apart, and included their biological children in the decision making process as well. “The kids felt that if there were needs to be met and we could meet them, why wouldn’t we?” Carolyn said. Bringing the siblings back from Ethiopia proved complicated. United States restrictions on HIV adoptions resulted in endless paperwork and three- to ninemonth waiting periods. Those experiences led to the founding of Project Hopeful. Carolyn and Kiel also adopted a fourth child, Selah, who had Stage IV AIDS when they met her on a trip to Ethiopia to bring Sam, Rachel and Seth to the United States. This spring, the Twietmeyers were awaiting approval to travel to Ethiopia to pick up their latest adoptions, Selah’s brother Andarge, 16, and her sister, Eyerusalem, 15. Carolyn is finally answering the question that has been a part of her life since she was 6. She and Kiel are making a future possible for kids around the world. “We just set our priorities a lot different than most people,” she said.

Families, Caregivers Celebrate Life at Preemie Reunion
Nitric Oxide Therapy
By Kevin Davis At 13 years old, Berachah Dubose is a bright, curious, talented girl who enjoys classical music, plays cello and piano and likes watching old black and white movies. There was a time when her life and her future were in limbo. She and her parents drove some 12 hours from Washington, D.C., to Chicago to offer their gratitude to the doctors and nurses who helped their once critically ill, premature daughter become a healthy, thriving young girl. They were among hundreds of parents and children who came to Comer Children’s Hospital at the University of Chicago on October 11 for a reunion of parents, preemies and their caregivers from the Neonatal Intensive Care Unit (NICU).

At this premature stage, the baby faced the possibility of serious respiratory problems, brain hemorrhaging and a host of other physical and neurological complications that could last a lifetime. If the Ramos family were willing, the baby could be part of a clinical trial testing a new respiratory therapy for premature infants.

Still, Schreiber’s team continues to follow the original group and recently examined their readiness for school and the long-term safety of the therapy. They found that nitric oxide is as safe as a placebo, and may actually improve health. But they also found school readiness levels were similar between the children who received nitric oxide and those who didn’t. Schreiber believed this was likely because of the effects of the child’s social environment on development. Studies have shown socioeconomic factors influence development, and poor children are more likely to experience fragmented medical, developmental and educational support. The majority of the children in the study came from socially disadvantaged families. “Any benefit medicine can give to a baby, in a sense, can be undone by one’s socioeconomic status and lack of mental stimulation,” Schreiber said. “Poor children may not have access to quality, early intervention programs. We believe that’s so important to recognize.” Researchers are moving to the next step and will study nitric oxide’s effect during the critical period of brain development. They will compare infants receiving nitric oxide for seven days with another group receiving it through full term, covering that critical time of brain development. The success of patients inspires physicians to keep looking for new methods. “Babies, like Sara, are why I wake up in the morning, anxious to pursue new studies,” Schreiber said. “This is why we do what we do.”

“It’s exciting to see my old nurses and doctors,” said Berachah, who was born at 26 weeks and weighed 1 pound, 8 ounces. “I know how these young kids feel.” “It means a lot to her to keep that connection” said her father, Michael DuBose, a music teacher. The family, who moved to the Washington area four years ago, has been coming to the reunion for every one of Berachah’s 13 years. In all, more than 500 people attended the reunion and health fair at the Duchossois Center for Advanced Medicine where children — who were once tiny preemies — jumped in a bounce house, had their faces painted, played games and giggled with clowns. “It’s amazing to all of us,” said Nicholas O’Hearn, RN, director of pediatric and NICU nursing. “We had these children when they were at their most vulnerable. We rarely, if ever, get to see the fruits of our labor.” Many nurses were clearly moved after being reunited with these children who came to them as the tiniest of infants, some weighing just barely more than a pound, fragile and struggling to breathe. “The nurses have a lot of compassion to take care of the babies like this. It takes very special people,” said Kim Mlynski, a staff nurse in the NICU and coordinator of the reunion. “We send them on their way, and we don’t know what they’re going to end up like. It’s amazing to see them when they are walking and talking. It touches your heart.” Renee Hubbs of Chicago brought her Renee Hubbs and Alyssa at the reunion. daughter, Alyssa, now 2 years old and weighing 30 pounds. Born at 24 weeks, Alyssa was 1 pound, 11 ounces and remained on a ventilator for a month. Her mother said she was the size of a small water bottle. “The nurses were really phenomenal. They helped us through,” Hubbs said. Andy and Andrea Kmieciak, of LaGrange Park, Ill., brought their twins, Nicholas and Tyler, 16 months. Both were born weighing less than two pounds at 24 weeks and spent more than four months in the hospital. They reunited with nurses Kristie Minton and Brittany Hayes. “We had fantastic nurses,” Andy Kmieciak said, “and were blessed to have great care.” Spring/Summer 2010 41
SPREADING Pritzker ABROAD By Greg Borzo
When Olufunmilayo Olopade, MD, FACP, and associate dean of the University of Chicago Medical Center’s new Global Health Initiative, surveyed the faculty to gauge the university’s presence around the world, she was surprised to learn that faculty members were already active in more than 100 different countries.

Getting to Know the South Side: Pritzker Day of Service By Allison Horton First-year medical students got a chance to learn more about the South Side neighborhoods served by the Medical Center through participating in the second annual “Pritzker Day of Service.” “The idea is to introduce first-year medical students to this community and also to give some manpower to ongoing community service projects in South Chicago,” said Laura Blinkhorn, a secondyear medical student involved in the Pritzker Community Service Fellowship, a student organization that sponsored the event last fall and is devoted to developing physician leaders. She helped direct other medical students last year as they prepared a community garden for the winter. Blinkhorn was one of more than 20 Pritzker School of Medicine students who harvested crops, such as peppers and tomatoes, and turned over the garden for the South Chicago Art Center, 3217 E. 91st St., which provides free in-school and after-school art programs to eight schools in the Washington Park and Englewood neighborhoods. Community residents take care of the garden and receive the crops, which help an area where the average annual household income of $12,000 is well below the poverty line. Any excess produce is donated to local food pantries.
Sarah Ward, executive director of the art center, said the garden was once a parking lot for area steel mills and a gas station. “I wanted the kids to feel better about themselves,” she said. “To be able to see a butterfly land on a flower and draw it and enjoy the outdoors that’s not concrete and broken glass,” she said. Other Pritzker students volunteered at the Gary Comer Youth Center, 7200 S. Ingleside Ave., which provides after-school programs such as health and wellness classes, academic tutoring and college mentoring to youth in the Grand Crossing neighborhood. The center also is home to the South Shore Drill Team, a nearly 30-year-old organization that trains young people to perform flag, rifle and dance routines and takes them around the world to show their stuff. More than 50 medical students cleaned fitness equipment, worked in a rooftop garden and helped kids make Halloween crafts. Gabrielle Zeigler, a 16-year-old Hyde Park Academy student who has been attending the center for three years, said she enjoyed doing Halloween crafts with the medical students. “It was fun,” she said. “We got a chance to meet new people and work with them. If we needed extra help with what we were doing, we had the extra help.”

Rebecca Levine, a second-year medical student and a fellowship board member, said volunteering helps the Medical Center grow roots in the community. “There is a significant degree of passion at our school for service and for giving back, and we are really focusing on these long-term partnerships in the South Side neighborhoods,” she said.
Peer-to-Peer Mentoring at Pritzker By Susan Chandler The Pritzker School of Medicine has always provided counseling to students during their third year, a stressful watershed when they move out of the classroom and into hospitals. Some students may be seeing seriously ill and dying people for the first time. On top of that, third-years must decide what area of medicine to specialize in. That adds up to a lot of pressure. Much of the career guidance students receive comes from Pritzker faculty members through formal advising societies. Two Pritzker students in their fourth year decided some grass-roots input was needed. In August, Josephine Kim and Gautam Malhotra approached Shalini Reddy, MD, associate dean for student programs and professional development, with an idea. Why not ask fourth-year students to act as mentors to third-years and post their profiles so the third-years could see which
students shared their same career or personal interests? Reddy gave the go-ahead and so far, more than half of the fourth-year class has signed up to be mentors. “It is a fantastic addition,” said Reddy. “Peer mentoring provides perspective. If you’re talking to someone who has been through what you’re going through, you take it to heart. I think there’s a need for connectedness because medical students tend to feel they’re experiencing everything by themselves. I want them to know they have each other.” The issues that concern third-years may run the gamut from “When can I find time to exercise?” and “What should I eat?” to “Someone just died. How do I handle it?” Reddy said. Kim says the idea for peer mentoring came to her at the end of her third year when she was looking for someone to talk
to about choosing obstetrics/gynecology as a specialty. A friend suggested she talk to another student who turned out to be “unbelievably helpful,” Kim said. Prospective mentors were asked to fill out a survey listing their choice of field, organization memberships, research work and hobbies. That information is being posted on a website where third-years can make their own choice about whom to contact. There’s a risk, of course, that fourthyear mentors may find themselves busier than they expect and not be as diligent as hoped about responding to inquiries. There’s also the chance that the program will fade away after Kim and Malhotra move on. But Kim says they won’t let that happen. “We haven’t laid out the nitty gritty yet, but we’ll make sure it gets passed on.”

This Future Doc
John Paro has spent much of his young life entertaining others. Whether mimicking the sounds of stringed instruments with his mouth in an a cappella choir, banging drums in a punk rock band at frat parties, or channeling Eddie Van Halen for drunken bachelorettes, Paro has enjoyed amusing his varied audiences. But when Paro entered the Pritzker School of Medicine in 2006, he thought his minstrel ways were behind him. Not so, apparently. During his first year, Paro struggled to remember medical terms for an upcoming anatomy exam and started strumming his guitar during study breaks. The result was a techno dance tune called “Shake That Lower Limb” that used complicated medical terms to describe the lower anatomy parts a man uses while dancing. Paro e-mailed the song to his classmates as a joke. “I thought they would just delete it,” said Paro, now 26 and finishing his fourth year. “But they liked it, and they sent it out to their friends.” So Paro wrote another song called the “Pelvis Ho-Down” set to country music, the chorus of which goes like this: “Shake your labia, Shake your testicles according to which gender you belong give it up for labia, yee-haw for testicles come on everybody sing this song.” There are lots of medical terms, like Ileum, Ischium, Sacrum and Coccyx, thrown in there, too, along with detailed accounts of cadaver dissections, but we’ll skip over those parts. Suffice it to say, Paro was writing and singing for a specific audience. “People started telling me that they remembered terms for tests by singing my lyrics,” said Paro, a tall, thin, tawny-haired man whose wide grin and eagerness evoke Doogie Howser more than Dr. House. That was all the encouragement Paro needed to keep playing. “I started incorporating more class material into the songs,” he said. He modeled his lyrics after the School House Rock cartoons in which lessons in English, history and politics are delivered in

mnemonic rhyming lyrics that almost anyone who came of age after the 1970s can recite, like: “Conjunction Junction, what’s your function?” or “I’m just a bill. Yes, I’m only a bill. And I’m sitting here on Capitol Hill.” Paro remembered the silly lyrics from his own middle school days, and he thought the technique could help him in medical school. “For me it was a hobby. It allowed me to entertain my classmates,” he said. “Half of it was entertaining, and half was using effectual memory tools.” But then his audience grew. Classmates were sending the songs to other medical students at other schools. “Then I started thinking that maybe this is marketable,” he said. This past summer, just as he was about to enter his final year of medical school, Paro decided to make a CD. By then, he had more than a dozen songs written. So he took out references to Pritzker — the inside jokes that only his cohorts could understand — and recorded the album that he named “MedSchoolRock.” Paro layered the instruments on the tracks by using a software program called Garage Band. He recorded each track separately in his music studio — the extra bedroom that converts into a guest bedroom when company arrives at the apartment he shares with his fiancé, Renee Rodriguez, also a Pritzker medical student. While laying down the vocal track for “Taco Bell’s Canon,” a song that deals with the various causes of a common medical condition, Paro had to keep chanting “diarrhea, diarrhea” as loud as he could into the microphone. “I just knew my neighbors thought I was nuts,” he recalled, laughing.
The dedication has paid off, though. The album sells on iTunes and also is available at Amazon.com. Paro also has a website, www.medschoolrock.com where people can listen to the songs and read the complicated lyrics. Paro gets a percentage of sales, which so far has netted him a few hundred dollars. Paro insists that if the CD takes off, he’d like to establish a mini-scholarship fund in which he would hand out $500 to medical students each year to support their outside interests and hobbies. The application would be a paragraph in an e-mail that would explain how the student would use the money to further a hobby, like buying a new camera for a photo buff. The concept may seem a bit lofty, but Paro is a strong believer in living a balanced life. “People often ask me how I have time to write songs and play music,” he said. “Some people can study from 10 a.m. to midnight. I can’t. I reach a critical point, and then I have to do something else.” Though he’d decided to become a doctor while in high school in Hinsdale in Chicago’s west suburbs, Paro was determined to have John Paro in his home recording studio.

American medicine is a behemoth of special interests that contributes to, as well as consumes, our economy. The American adage, “You have nothing without your health,” is the philosophy behind our ever-expanding, entropic health industry. A systematic and well-planned approach is needed to navigate a useful and lasting change to the current health delivery system. This will require completely dismantling and rebuilding our medical delivery system in a way that focuses on the doctor-patient relationship as its core mission. The doctor-patient relationship is alive within American medicine, though it is under attack by government policy, agencies, third-party insurers, pharmaceutical and device manufacturers and hospital conglomerates that secure huge profits without personal risk. The economics of health care costs have no seat at the doctor-patient table. The recent health care bill alienates this relationship further. The commerce of health maintenance or treatment will continue to be carried out without participation from these two key players and an understanding of the true cost of care. Charges are so extremely high that it defies any logical ability to qualify them to me, a doctor, or to the patient who is billed. Having health care rates negotiated between a doctor and patient rather than an insurance company and hospital or declared by the federal government would instantly contain costs. The special interests in the American health system do not want this action. The current system does not reward quality or complexity of care, which can only be judged by a patient and a doctor, not the “Wizard of Oz” behind a curtain. My fear that health care reform will not be done systematically and, consequently, will perpetuate the current third-party payer system in lieu of a strong nonprofit, fiscally sound public insurance option focusing on quality doctor-patient interaction is realized. It is egregious that health insurance executives are paid tens of millions of dollars annually because they raise premiums and pay providers less. How do we negotiate this corruption in our care of sick Americans? Wall Street encourages it, while our government believes this greed can be regulated. It is hard to rationalize sanely that expanding the current third-party payer system, without a sound, competitive, nonprofit public option, can be done without huge cost to patients, their care and the clinical caregivers delivering it.
Recently, a middle-aged gentleman came into my office for the first time after a three-day hospital stay for newly diagnosed congestive heart failure. The heart failure was caused by longstanding hypertension, which he never knew because he had not seen a doctor in almost 20 years. In his reasoning, why would he? He always felt fine. Besides, he didn’t have health coverage and could not afford to see a doctor. He worked but did not qualify for Medicaid insurance. He was referred to my federally qualified health center because of proximity to his home and our sliding-scale fee for the uninsured. Within this scope, he could establish a medical home for office visits and blood work and be connected with low-cost, generic medicines. But without insurance, he could not get diagnostic tests or a subspecialist’s consult, if needed. Especially with these barriers, I silently hoped we could stave off these needs. At his appointment, we discussed the new medications he’ll need to stay out of the hospital and improve his outcome. He’ll have regular office visits to monitor his symptoms, blood pressure and lab work. Nevertheless, statistics show heart failure will limit his life expectancy. I wish he were not in this predicament and that he received regular health care before his condition progressed to hypertension and heart failure. Diet and exercise could have been significant prescriptions in controlling this disease in early stages, but he didn’t receive that medical advice 20 years ago. At this point, even if there were affordable insurance options for him, he would have been denied coverage with these diagnoses. Our current health care system failed this patient and thousands like him. Medical benefits are primarily tied to employment, but not all employers can provide these benefits. For those with insurance, more often the care of disease is paid, but preventive measures are not, so paradoxically, we finance a sicker society. Once a patient has a disease considered to be a pre-existing condition, the next time the patient tries to get health insurance, obtaining coverage may be impossible. And those with chronic conditions also face loss of medical coverage and limited health care options if they lose their jobs. Thankfully, health care reform legislation addresses these issues; however, it does not comprehensively cover all individuals who live in this country. And there will be temporary gaps for many based on the timetable of rolling out various components of reform. However, these first steps are big gains that move us in the right direction.
Three headlines from The New York Times on November 9, 2009, illustrated the problems posed by the health care revolution.
My greatest hope for health care reform is that it will transform health care economics to be more focused on patients and their health. The current system is entirely unsustainable. While we pay vastly more per capita than any other industrialized country, objective measures of health outcomes consistently show that our system fails to provide us with appreciably better results than countries spending a fraction of what we do. This results from several fundamental flaws that must be addressed. First, the current for-profit health care model creates a fundamental conflict between patients’ needs and insurance companies’ goals. Patients suffering with illness should not have to fight with their insurance companies to cover needed care. The health care system should be structured to protect patients and not to deny them care and drive them into bankruptcy in order to support company profits. While provisions in the bill to prevent denial of care based on pre-existing conditions are a tremendous leap forward, we must also ensure that patients have unencumbered access to requisite care. Second, by heavily relying on an employer-based insurance system, patients are placed at enormous risk if they lose their jobs or if they’re self-employed and cannot afford high insurance premiums. This sets up a vicious cycle with unemployment leading to the loss of insurance resulting in deterioration of health, making it difficult to re-enter the workforce. While the recently passed health bill works to alleviate this problem, rapidly rising insurance premiums may outstrip government subsidies and re-establish a situation in which health care remains unaffordable to many. Finally, the present fee-for-service model of physician reimbursement should be replaced with a system that rewards doctors for improving the health of their patients. This will undoubtedly be a challenge since doctors may be wary of setting up practice in communities with pre-existing poor health. But if we want a health care system that works, we need to appropriately align the interests of all involved to the ultimate goal of patients’ health. The cumulative effect of this would be to ensure that more patients are getting highly-involved, quality care while simultaneously reducing costs through the abandonment of diagnostic and therapeutic approaches that don’t work. My greatest disappointment with health care reform is that it stopped short of universal coverage, and I fear that we will lose the political will to change the fundamental flaws in the system. This moment in history offers a unique opportunity to address the disparities in health care that are tremendous barriers to social equality in our country. If we neglect to meet this challenge now, we risk perpetuating a system that fails all of us.

“Sweeping Health Care Overhaul Passes the House: Slim Margin for Plan to Cover 36 Million” It is good that our health
care system is striving to pay for the care of more than 36 million uninsured Americans but regrettable that we will still fall short of universal coverage. “Abortion Was at the Heart of Last Minute Wrangling Over a Contentious Bill” Abortion is a relatively small part of the health
care issue. It should not be a central focus. It is shameful that political wrangling and obstructionist methods impede progress. “Curing Health Care” American health care is the most expensive without providing better results. The infant mortality rate in the United States is the highest among 16 nations; life expectancy of American newborns is 1.7 years less than the non-U.S. average. Americans neither live longer nor do we have better results from cancer therapy than other nations. My suggestions: 1. Initiate change where government control already exists. Allow Medicare patients to access government-controlled health care systems, such as the Veterans Affairs, the Public Health Service facilities and perhaps even military facilities, by adding the required resources and making the needed changes. 2. Decrease costs by changing practice patterns. Existing practices are inefficient. For example, nearly all patients with acute appendicitis do not need CT scans for diagnosis and cure. The army of employees for billing is excessive. A system that provides rewards for resisting overuse of testing and therapies should be developed. Only qualified medical practitioners can decide how to trim fat, maintain quality and allow doctors the freedom needed for individual care. 3. Give leadership roles and authority to people who have personal experience in the practice of medicine. A common denominator among Mayo Clinic, Cleveland Clinic and Kaiser-Permanente, frequently cited as models, is their leadership by doctors who have actively practiced. The health care bill has passed — a giant step forward. Too bad that it will be four years before mandated changes occur and that cost containment efforts continue to be largely the turf of administrators instead of the responsibility of doctors. It is time to stop being politically correct and timid. Let us step forward with courage and determination to reform health care.
