I-SPY 2 can test new treatments with significantly fewer participants and in half the traditional time, which will dramatically lower costs. The trial, launched two years ago, is screening multiple cancer drugs at 19 major cancer research centers across the country, including CU Cancer Center.

TIGHTENING THE BODY’S
At CU Cancer Center, researchers discover how dinosaurs, diabetes, Star Trek extras and Keith Richards combine to keep the body cancer-free.
nterstate 70 is bad enough on a normal Monday evening, let alone when an accident makes the freeway look more like long-term parking at Denver International Airport. And so it’s easy to sit there, stewing, scanning radio stations, and thinking about what could possibly have caused the accident in front of you and why the highway patrol can’t move the wreck to the median. I mean—sheesh—you could be home by now sitting comfortably on the couch and grumbling about Peyton Manning’s arm! That is, if it weren’t for that darn accident. But look at it another way: most nights the freeway is packed with 4,000-pound chunks of fire-propelled metal, hurtling across the pavement at 70 mph while their pilots shove their heads in Cheetos bags or fidget with their supposedly hands-free smart phone systems. Some of these people you wouldn’t trust with a popcorn maker let alone a Hummer. Really, it’s pretty astounding there aren’t more accidents. The same is true of cancer. Cancer research centers tend to focus on what to do once the body is sick, once an accident is already on the road. For example, at University of Colorado Cancer Center when a patient walks in the door the physician asks what went wrong and how to fix it. “But maybe a better question is, for all the people we don’t see, what goes right,” says Andrew Thorburn, PhD, deputy director of CU Cancer Center. He points out that there are about 10 to 100 trillion cells in the human body, with 50 to 60 billion cells replaced every day. That’s 50 to 60 billion chances per day that a cell can accidentally accumulate a mutation or combination of mutations that cause cancer. Like cars on a fast freeway, “You look at those odds and it’s surprising that cancer isn’t more prevalent,” Thorburn says. Or maybe it’s not that surprising after all.

Andrew Thorburn, PhD, with professional research assistant Josh Thompson and postdoctoral researcher Paola Maycotte.
It’s no random accident—no game of Russian roulette—that keeps the body cancer free. Instead it’s a handful of precise mechanisms that Thorburn calls “prerequisites of multi cellular life” that have evolved to ensure we stay healthy long enough to pass on our genes. Researchers at CU Cancer Center and elsewhere are broadening their focus to explore not only what goes wrong when we get cancer, but what goes right when we don’t.
“MAYBE A BETTER QUESTION IS, FOR ALL
P LAC E O R I G I NAL FAC E D OWN O N G LAS S
First, “the body has an astoundingly precise copy machine,” Thorburn says. When a cell divides, it copies the full expanse of its DNA, giving away a copy to its daughter cell and keeping a copy for itself. The code of life is made up of only four bits of information, called nucleotides, which when strung together can look something like this: ATGACGGAGCTTCGG. If you were sitting at a keyboard, could you look at this code and reproduce it? What would be your error rate? The body’s error rate is only about one mistake in every 100,000 nucleotides. That’s pretty darn good. (See “Decoding Cancer,” page 9.) Now imagine the 30,000-ish genes included in every human cell’s DNA—the blueprints for all the construction and workings of your body. Each gene is made up of about 3,000 nucleotide base pairs. That’s not all: functional genes make up only about 2 percent of your DNA and so in all you have around 6 billion nucleotide base pairs in each cell’s DNA. This means that despite the body’s careful copy machine, each new cell is likely to have about 120,000 mutations. Now multiply that by 50 to 60 billion cells and you get…well, you get a really big number that you certainly don’t want to see printed here.

So in addition to an accurate copy machine, the body also has an accurate proofreader. Instead of accepting these mutations, the body tries to identify and fix them. A cell builds DNA by stacking it one nucleotide at a time. And as it stacks nucleotides, the cell has enzymes that crawl along the original DNA, comparing it to the copy. When an enzyme finds an error—say a G that should be an A—it pulls the mistake and inserts a correction. The cell’s proofreading mechanism catches and fixes about 99 percent of errors this way—good but not nearly good enough to keep mutations out of your genome. The more cells you need to replace (for example, because you kill cells with a sunburn), and the higher a cell’s mutation rate (say, because the sun’s UV rays slice and dice DNA like Dan Aykroyd’s Super Bassomatic on “Saturday Night Live”), the more mutations make their way past the copy machine and proofreader. Now the body’s job switches from fixing errors to eliminating them.

Jill Slansky, PhD, co-leader of the Immunology and Immunotherapy Program at CU Cancer Center and National Jewish Health.
As you’d expect, one recognizer-and-killer is the immune system. But it’s tricky: cancer cells are your own cells gone bad. Your immune system is supposed to kill foreign cells like bacteria and viruses, not your own cells, and so it has difficulty turning its firepower on more domestic terrorists. Interestingly, there’s one kind of person whose immune system does kill cancer cells and that’s people with autoimmune diseases like Type 1 diabetes, in which the immune system’s T-cells erroneously attack the pancreas’s insulin-producing cells. Patients with Type 1 diabetes almost never get pancreatic cancer. And patients with the autoimmune condition vitiligo, in which T-cells attack the skin’s pigment-producing cells, are dramatically protected against skin cancer. It seems that an over-sensitive immune system kills cancer cells first. On the flip side, people who are immunocompromised, as are those with HIV, have higher rates of many cancers. “When you develop a cancer, by definition soft tissue has gone haywire. And when you develop an autoimmune condition like Type 1 diabetes, by definition your T-cells have gone haywire,” says David Wagner, PhD, CU Cancer Center investigator and associate professor of medicine at the CU School of Medicine. “Perhaps we could push T-cells to just beneath this threshold of ‘haywire’ to combat the cancer cells that have already gone past this tipping point.” It’s like your email spam filter: one form of cancer immunology seeks to dial up the sensitivity of your immune system’s spam filter in order to route cancer cells to the “kill” folder, perhaps destroying some healthy cells along the way. Wagner is working to control T-cell sensitivity with a protein called CD40. Tweaking CD40 in one direction makes T-cells more aggressive and tweaking it in another direction makes T-cells more docile. Other CU Cancer Center immunologists are working with vaccines to sensitize T-cells against cancer. According to Jill Slansky, PhD, co-leader of the Immunology and Immunotherapy Program at CU Cancer Center and National Jewish Health, here’s one way it works: “The immune system is designed to recognize abnormal proteins and kill the cells that present these proteins. Due to mutations, cancer cells make abnormal proteins, but because cancer cells also share so much similarity with the body’s own, healthy cells, the immune response may not be very strong. “We’re working to boost the sensitivity of T-cells to these tumor-specific antigens. Like any vaccine, if you can give T-cells a preview of these foreign proteins, you can sensitize T-cells to recognizing these proteins on actual cells,” Slansky says.

In fact, cells containing cancer-causing mutations might not even need the intervention of the immune system to end up dead. “Cells are hardwired to kill themselves if there’s something wrong with them,” says Thorburn, whose research focuses on this programmed cell suicide called apoptosis. “If a cell’s in the wrong place or growing at the wrong time, healthy cells have this natural default to just kill themselves.” Like an unnamed character tagging along with the “Star Trek” crew on an unexplored planet, cells are expendable. So the body errs on the side of caution—one teeny-tiny false move in the way a cell goes about its business can show that it harbors a dangerous mutation, and the body would rather throw the cell under the bus than risk it spawning a dangerous tumor. For example, if you’ve taken high school biology, you probably still have that dream where you’re sitting at a desk, pencil in hand, no clothes, staring at an unexpected test on the stages of the cell cycle. Messing up the steps of the cell cycle won’t help your biology grade and it doesn’t help most cancer cells, either. That’s because the body places customs agents at the boundary of each step. If a cell rushes through or tries to skip a stage of cell division, tumor suppressor genes (customs agents) recognize the cell and mark it for apoptosis. Likewise, these regulators look for broken DNA, unnatural bulging or misarranged chromosomes—any one of these can mark a cancerous cell and any one can get a cell marked for apoptosis. So in addition to a mutation that allows an early cancer cell to act cancerous, cancer cells also include mutations to these anti-tumor or tumor suppressor genes, making them toothless. In fact, “Simply disabling some of those anti-cancer genes is sufficient to create cancer,” says Thorburn, “and ironically, cancer cells are often easier to push into apoptosis than healthy cells—it’s as if they were trying to kill themselves and just didn’t quite manage it.”
D I N O SAU R S , K E I TH R I C H AR D S AN D TH E B O DY’ S C H A N G I N G T I S SU E LAN D S CAP E Then in addition to accurate copying, the immune system and apoptosis, there’s the role of the tissue surrounding mutated cells. Sure, the older you are, the higher likelihood that one of your 50 to 60 billion cell duplications per day will result in a sneaky mutation that avoids control, but Cancer Center researcher James DeGregori, PhD, shows that it’s not only the increasing chance of a mutation with time that leads to higher cancer rates in older adults. “You put an early cancer cell in healthy tissue and that cancer cell is unlikely to survive,” says DeGregori, professor of molecular biology at the CU School of Medicine. “It’s like what happened to the dinosaurs 65 million years ago. Dinosaurs were great and they weren’t changing that fast; they were well adapted to their landscape. Until that darn meteor. Suddenly dinosaurs weren’t a good fit for the new landscape. The species didn’t have to change their mutation rate; it was the new landscape that drove speciation. “Similarly, what primarily drives cancer rates higher as we age is the changed landscape,” he says. Our healthy cells are optimized for the conditions of our healthy, younger tissue. In fact, they’re so perfectly optimized for young tissue that changing anything about a cell makes it less fit for its surroundings. That’s the case of cancer cells—they’re different
James DeGregori, PhD (standing), with postdoctoral researcher Curtis Henry.

VE E R
and thus less fit, and so healthy cells simply out compete them. The young body uses basic survival-of-the-fittest to keep cancer in check. But, “when tissue is old, healthy cells are no longer a perfect fit for the landscape, and mutations might help a cancer cell adapt in ways a healthy cell can’t,” DeGregori says. Blot out the sun with a meteor’s cloud of dust and mammals will eventually outcompete thunder lizards. Age or transform tissue until it’s far enough from its healthy norm and cancer cells can outcompete their healthy peers. DeGregori’s work supports the conclusions of CU Cancer Center investigators Pepper Schedin, PhD, and Ginger Borges, MD, who work with the tissue landscapes that give rise to breast cancers. “We see that breasts with higher rates of inflammation—as those undergoing the process of involution during which milk-producing cells are replaced by fat cells—have higher rates of both initial cancer and metastasis,” Schedin says. Inflammation and a dramatically changing tissue landscape leave healthy cells looking for their footing, while cancer cells, like dandelions, take advantage of the disturbed earth. Borges and Schedin’s work explores the use of non-steroidal anti-inflammatory drugs like ibuprofen to reduce inflammation in these tissues, hopefully bringing it in line with the conditions for which healthy cells are optimized.
OBESITY AND THE CHALLENGE OF PROVING PREVENTION
“THE REAL DIFFICULTY IN EXPLORING ANY OF THESE PREVENTATIVE STRATEGIES IS THE LOGISTICAL AND ETHICAL DIFFICULTY OF PRESCRIBING ANY INTERVENTION FOR PEOPLE WHO AREN’T YET SICK.” —ANDREW THORBURN, PhD
The influence of tissue on cancer is also important on a more global scale. The process of breast involution, sunburn and smoking are not the only ways to create inflammation. Obesity can also create cancer risk. (Read “Battle of the Bulge” in the previous edition of C3 at www.coloradocancerblogs.org for details.) In fact, Tim Byers, MD, MPH, professor of epidemiology at the Colorado School of Public Health and associate director for prevention and control at CU Cancer Center, believes that in many cases an intentional 10 percent weight loss after surgery for breast cancer can be as effective as adjuvant chemotherapy in preventing relapse. Knowing these mechanisms the body uses to stay cancer free, you’d think we could design and test interventions to help the body with its work and artificially boost its defenses. Unfortunately, “the real difficulty in exploring any of these preventative strategies is the logistical and ethical difficulty of prescribing any intervention for people who aren’t yet sick,” Thorburn says. For example, you can’t give 1,000 women ibuprofen and compare their breast cancer rates to 1,000 women given sugar pills. Likewise, you can’t experimentally introduce cancer proteins in a vaccine to people who don’t yet have the disease. Thus, prevention strategies are tricky to prove. But the times they are a-changing. Like CU Cancer Center, other cancer centers are starting to prioritize their departments of prevention and control. And cancer vaccines, including the drug Yervoy for metastatic melanoma and Gardasil for HPV that causes genitourinary cancers in men and women, have gone from fringe science to FDA approval. Next time you’re stuck in an I-70 traffic jam, instead of fretting in a way that’s really not good for your blood pressure, try being thankful that accidents are rare. In addition to being courageous as you face cancer, offering your compassion to others affected, and helping support organizations looking for tomorrow’s best fixes, take a minute to marvel at the body’s ability to get it right so often. We are machines made to resist cancer. By understanding how these machines work, we may find ways to help them resist cancer just a little bit better.

Outliving the Odds IN 20 YEARS, HARRY PETERSON EXHAUSTS HIS DOCTOR’S “BAG OF TRICKS,” FINDS HOPE IN A CLINICAL TRIAL BY K I M C H R I SCA D E N
WATC H F U L B UT WAI TI N G This year nearly 242,000 American men will be diagnosed with prostate cancer, the most common cancer in men. Of those diagnosed, nearly two thirds are 65 or older. Very few cases are diagnosed prior to age 40. Although most men die with and not from prostate cancer, still, nearly 30,000 lose their lives every year. At 65, Harry’s first warning signs were an elevated prostatespecific antigen (PSA) and a small growth on his prostate. After a sonogram and biopsy, the growth was found to be benign. A number of benign prostate conditions can cause an elevated PSA so Harry and his physician weren’t too concerned. “Back in the day they didn’t take a lot of specimens,” Harry recalls. “At first, my prostate cancer didn’t develop a lot of PSA; it wasn’t as elevated as the doctors were looking for.” Harry and his physician decided it was best to continue to monitor his PSA, a strategy called “watchful waiting,” to see if levels stabilized. While Harry waited, his brother-in-law was also diagnosed with prostate cancer. Unlike Harry, his PSA climbed drastically in a short period of time. He opted for brachytherapy, a type of treatment where tiny radioactive pellets are implanted in the prostate to kill the tumor. Harry had a feeling it was time for him to go back to his doctor. Could his PSA also be rising? By now it was 1996. Four years had passed since the watchful waiting began, but his PSA graphs were inconclusive. He decided it was time to have another sonogram and a set of biopsies. They were conclusive: Harry had cancer.
Rather than undergo brachytherapy like his brother-in-law, Harry opted for a radical prostatectomy in early 1997. He hoped by removing the cancerous prostate he’d be cancer free. He wasn’t so lucky. “It turned out that the cancer was everywhere and it wasn’t slow-growing,” Harry says. “It was a seven on the Gleason scale.” The Gleason scale is the most common system used to grade prostate cancer. Scores range from two to 10. In order to come up with the Gleason score, a pathologist looks at the patterns of cells in the prostate tissue samples. The most common pattern of cells is given a grade of one to five. Five is the most abnormal. An additional score is given to a second common pattern of one to five and these two scores are added together to get the Gleason sum score. With a Gleason score of seven, Harry’s life expectancy was five years at best, he was told. Despite the odds, he wanted to face cancer the same way he faced work and life—with perfection.
N EVE R F I N I S H E D Harry has had to get through good times and bad for more than 60 years—thankfully, he’s had his wife right by his side all those years. As a 19-year-old college sophomore at Colorado A&M, now Colorado State University, Harry married Delores, “Dee,” his high school sweetheart. “We didn’t know any better when we got married,” Harry says. “Our moms were a little upset. They didn’t think we’d make it through school.” Determined to beat the odds, Harry finished his bachelor’s. Subsequently, he was accepted into the engineering mechanics PhD program at Cornell University and was offered a teaching G LEN N AS AKAWA
hen Harry Peterson, a retired engineering professor, had his first prostate cancer scare, Bill Clinton was in his first term as president of the United States. More than 20 years have passed since President Clinton was elected and two more presidents have served, yet Harry, now 81, continues to fight prostate cancer—despite exhausting two doctors’ “bags of tricks.” “I was beyond what my urologist and oncologist Dr. David Link could offer,” Harry explains. “I was at the end of the road. I’d had such good luck with previous treatments—and then to live for 15-plus years, it was a big surprise to see everything go to pot.” Today, Harry’s not giving up hope. He’s turned to urologic medical oncologist Thomas Flaig, MD, and a clinical trial at the University of Colorado Cancer Center. “This clinical trial is a unique treatment option not available at other places in Colorado,” says Flaig. “Patients like Harry have the opportunity to participate in trials that determine the effectiveness of a new a hormonal agent for prostate cancer.” By choosing the clinical trial of a genetically targeted treatment, Harry anticipates he’ll avoid chemotherapy’s harsh side effects and outlive his latest prognosis.

position. This was the start of his career as an engineering professor, eventually leading him to the Martin Marietta Corporation (now Lockheed Martin), University of Denver and Colorado School of Mines. In the late 1960’s, Harry began researching motorcycle accidents and rider injuries through computer simulation with the U.S. Department of Transportation and a British testing lab. His research concluded the need for leg protectors and redesigned fuel systems. “Back then guys were basically riding around with tin cans between their legs that could easily catch on fire,” Harry explains. “We researched ways to prevent severe leg burns and injuries.” By 1973, Harry was an expert witness in motorcycle accidents around the country. That work, plus teaching, kept him busy up until 1995, when he retired. “I was never able to put my work aside,” says Harry. “I couldn’t stop working until it was complete. Some people call it perfectionism; it was my life.”
AN OT H E R F I VE, 1 0 Y EAR S
FLICKR CREATIV E CO MM ONS
With determination, Harry survived the first five years post prostatectomy, despite rising and falling PSA’s. Six months of radiation helped his PSA drop, but it escalated once treatment was complete. “When he first started treatment, Harry’s urologist said if he could keep him alive for five years there would probably be better drugs available for someone like him,” Dee says. “Well, that was years ago,” Harry chimes in. “The good Lord must have been looking out for me because those five years are long gone.” In 1999, Harry started leuprolide (Lupron) injections every four months to help decrease testosterone, prostate cancer’s fuel. Harry’s PSA started to drop and stabilize. Another 10 years flew by. By late 2010, Harry’s PSA was going wild. Leuprolide was failing. Hoping to again control the testosterone, his urologist introduced bicalutamide (Casodex) into his treatment regimen. Bicalutamide is another hormonal therapy that works to block the effects of testosterone in conjunction with leuprolide. The combination therapy didn’t work. The only option his oncologist had left was chemotherapy; life expectancy at that point wasn’t great—three months to three years. His oncologist’s “bag of tricks” was empty. “There were very few options left,” Dee says. “He was at the end.”
A L E S S TOX I C C H O I C E With only chemotherapy left, Harry’s oncologist contacted Dr. Flaig, who’s also the medical director of the Clinical Investigations Shared Resource at CU Cancer Center, to ask if any clinical trials were open for advanced prostate cancer patients. Harry was in luck.
The PREVAIL study, a global Phase III clinical trial of an investigational drug, was enrolling patients with advanced prostate cancer. Harry qualified and enrolled in 2011. At this point, his PSA was doubling every two months. “I was certainly praying I could get on the clinical trial,” says Harry, “but I worried it was a double-blind study. I could potentially get the placebo.” The randomized, double-blind, placebo-controlled, multinational PREVAIL trial enrolled 1,680 patients with metastatic prostate cancer who had progressed despite treatment with androgen deprivation therapy, like leuprolide or bicalutamide. In addition to standard-of-care treatments (Harry stayed on leuprolide), half of the participants get a placebo and the other half get the drug enzalutamide. “We’re looking to see if we can use a less toxic hormonal pill to treat advanced prostate cancer cases where we’d traditionally use chemotherapy,” says Flaig. “Enzalutamide has already been proven to help patients live longer in more advanced settings in which the patient has already received chemotherapy. Now we want to see if it works as well if used before chemotherapy.” In the year and a half Harry’s been on the clinical trial, he’s already started to feel better and he hasn’t had to endure the harsh side effects of chemotherapy. “The difference between the side effects of taking this pill versus undergoing chemotherapy is night and day for most patients,” Flaig explains. “The pill makes sense and we need to see if we can use it earlier in the process and delay the need for chemotherapy.” With time Harry has seen his PSA drop. More time will tell if it stabilizes. Right now, he doesn’t know if he’s taking the placebo or enzalutamide. “I really owe Dr. Flaig a debt. He’s kept me alive a lot longer than was expected,” Harry says. “I don’t think I was supposed to survive this long.” “It’s gratifying to see patients respond well to new treatments,” says Flaig. “We’ll be excited to see the results of this clinical trial in the months to come.” While it’s been a long 20 years, another year or two of waiting is just a drop in Harry’s bucket. Flaig hopes the trial’s results will be published in 2013. Until then, Harry continues to simply live.
LIVI N G LI F E Despite diabetes, arthritis and old age, Harry says, life’s been good. He hasn’t needed a support group. “I don’t know what I’d complain about,” he says. “For better or worse, it’s something that’s there, but it hasn’t made a big difference in our life.” When Harry’s arthritis isn’t getting the best of him, you’ll find him and a buddy tinkering with his English car collection. Today, he’s probably out working on his 1962 Morgan Drophead Coupe, a car “that outshines them all,” he says. He, too, is outshining prostate cancer.

New drugs changing prostate cancer treatment Like Harry Peterson (page 12), patients with advanced prostate cancer are directly benefiting from the development of new androgen-blocking drugs and immunotherapies. Recently, three new drugs have improved survival outcomes by curbing testosterone or training the body’s immune system to attack prostate cancer cells.
E N ZA LU TA M I D E AD D S M O NTH S TO SU RV IVA L
AB I RATE R O N E: AN OTH E R TE STO STE R O N E I N H I B ITO R
Prostate cancer cells need androgens, like the male hormone testosterone, to grow. For prostate cancer patients with cancer that has spread beyond the prostate, hormonal therapy or androgen deprivation therapy can help prevent further tumor growth and improve quality of life. Recently, enzalutamide (Xtandi®, MDV3100) came on the market with the best survival data ever seen in prostate cancer. It lowered PSA levels, shrunk tumors and extended survival of advanced prostate cancer patients who had undergone chemotherapy by five months. “This is a major advance. Not only do we see more survival benefit than from traditional chemotherapy, but the side effects of enzalutamide are much lower,” says Thomas Flaig, MD, medical director of the CU Cancer Center Clinical Investigations Shared Resource and co-author of the study. “It provides both more benefit and less harm—you get the quantification of more life, but also see quality of life improvements.” To the body, enzalutamide looks a little like testosterone—the same pieces of cell machinery that grab testosterone grab enzalutamide instead; but unlike testosterone, enzalutamide molecules don’t tell prostate cancer cells to grow. Other therapies make the body produce less testosterone: enzalutamide ensures the body can’t use the little testosterone it continues to produce. The FDA has approved the drug for treatment of advanced castrate-resistant prostate cancer in patients who have already been treated with the chemotherapy drug docetaxel (Taxoterne). Now researchers are studying whether it can improve survival outcomes for patients, like Harry, who haven’t been treated with chemotherapy. “Enzalutamide is a key member of a half dozen new and emerging drugs and the challenge of the next five years is to discover how to best time and potentially combine these new agents. But even at this early stage, enzalutamide is a game changer,” Flaig says.
Approved in 2011, abiraterone (Zytiga) has been shown to boost survival by more than three months for men whose cancer has progressed after chemotherapy with docetaxel. Abiraterone is a hormonal therapy that targets a protein called cytochrome P450 17A1—a key player in producing testosterone. The drug works in combination with prednisone to decrease the production of testosterone in the testes, adrenals and in the cancer itself. This class of drugs is called androgen biosynthesis inhibitors, and abiraterone was the first of its type approved by the FDA. Unlike chemotherapy, these new drugs kill fewer healthy cells along with the cancerous cells and so have fewer side effects. “Targeting cells’ androgen receptors is a new and exciting development in the field of prostate cancer therapy,” says E. David Crawford, MD, head of urologic oncology at CU Cancer Center. “As these new drugs make their way from the lab to clinic, we expect the ability to offer androgen antagonists to patients whose cancers have resisted other treatments.”

P R O STATE CAN C E R’ S F I R ST I M M U N OTH E RAPY For men who have advanced prostate cancer that is not responding to hormonal therapies, researchers are advancing the use of a new class of drugs known as immunotherapies, including the drug Provenge®. Provenge trains the body’s immune system to attack prostate cancer cells. The treatment involves removing the patient’s own white blood cells, mixing the cells with a drug designed to target prostate cancer cells, and then re-infusing the treated blood into the patient. The treatment is repeated three times over the course of a month. In 2010, data from the IMPACT trial showed patients who received Provenge lived on average more than four months longer than men who received the placebo treatment. While Provenge, Abiraterone and Enzalutamide are not cures, they offer hope to patients who previously exhausted all treatment options. “Even without the addition of any more drugs, we may now have the tools that in combination will allow us to extend the survival prognosis of a prostate cancer patient long enough to make prostate cancer a disease a patient is more likely to die with than from,” Crawford says. —Kim Chriscaden and Garth Sundem

SPENDS MONEY TO SAVE MONEY
…AND LIVES WITH ECONOMY’S CLIMB,
AGAIN FUNDS PREVENTION PROGRAMS
BY E R I K A MATI C H
rom 2004 to 2008, money from the Amendment 35 tobacco tax funded chronic disease prevention programs. Then the recession hit and the state redirected this money to other urgent needs. Now, with the economy’s slow climb from the doldrums, millions of dollars from Colorado’s tobacco tax are once again flowing. Researchers in cancer prevention programs at the University of Colorado Cancer Center are hopeful the money will impact the state’s cancer rates—and save both lives and health care costs in the long run. “The good news is programs to prevent cancer are being funded again,” says Tim Byers, MD, MPH, associate director of cancer prevention and control at CU Cancer Center and associate dean of public health practice at the Colorado School of Public Health. For example, CU Cancer Center projects that screen uninsured individuals for colon cancer, help smokers quit, and identify patients at risk for hereditary breast and colorectal cancer are rediscovering their footing due to returned Amendment 35 funding. “The competitive grants given because of Amendment 35 mean the best of the best evidence-based programs can once again compete for funding,” Byers says. “As a result, hundreds of people won’t get cancer and the health care system won’t have to bear those costs.”
BALAN C IN G TH E SM OKIN G BURDE N Smokers tend to tax the health care system, so the system should in turn tax smokers. That was the gist of the thinking in 2004, when 61 percent of Colorado voters approved Amendment 35 to increase taxes on cigarettes and other tobacco products. The thinking was right: Annual health care costs in the United States directly related to smoking are more than $1 billion. Approximately $425 million in income and produc tivity is lost every year due to premature death caused by smoking. And tobacco-related illnesses are the leading cause of preventable death in Colorado. Tax revenue went to programs that sought to balance these numbers—to prevent these preventable deaths and save the health care system the money it would eventually spend taking care of these smokers. For example, the statute requires 16 percent of tobacco tax revenues to be used for school funding of tobacco education programs aimed at keeping youth from smoking, smoking cessation programs and programs to reduce exposure to secondhand smoke. Another 16 percent goes to prevention, early detection and treatment of cancer, cardiovascular disease and chronic pulmonary disease. CU Cancer Center got a slice of each of these funds—and came to depend on these monies to keep the lights on in many of the Center’s prevention and control programs. When the economy went south, Colorado legislators declared a fiscal emergency. From 2009 to 2011 Amendment 35 funds were down in general—fewer people could afford to smoke. And these reduced funds were redirected to cover expanding Medicaid costs. Cancer prevention programs like CU Cancer Center’s Colorado Colorectal Screening Program saw their budgets slashed—free screenings were reduced and research projects went into maintenance mode.

O U T O F HI B E R NATI O N The economy goes up, tax revenues go up, prevention and control programs go up. Hopefully speaking, smoking and cancer rates will go down. With the first now gaining traction, CU Cancer Center researchers are starting to see the other three fall in line. Arnold Levinson, PhD, MJ, a tobacco control expert at the CU Cancer Center, is the scientific director on a new three-year, $600,000 grant to design, implement and evaluate smoking cessation treatment programs for tobacco-using patients in the University of Colorado Health system. The project—a collaboration between CU Cancer Center and University of Colorado Hospital (UCH)—brings together the academic expertise of Levinson’s research group with system-wide access to patients in three University of Colorado Health hospitals: UCH, Poudre Valley Hospital and Medical Center of the Rockies. “We hope our initiative will serve as a model for other hospitals,” Levinson says. Byers hopes the program will directly result in quitting. “About 17 percent of the population in Colorado smokes,” he says. “There is really no reason we can’t continue to drive down that number.”
“Hopefully, by identifying high-risk patients, clinics can prioritize their already limited resources for subsidized screenings,” she explains. Colorado Generations matches medically underserved Coloradans with genetic counselors who can help assess cancer risk, coordinate testing and make screening recommendations for those at especially LO W ERY high risk for hereditary cancers. “The goal is to increase awareness about family history and hereditary cancer risk among patients and their providers,” Lowery says. “We want them to know what it is and whether it may affect them so that they can get appropriate care and make informed, pro-active decisions about their health.” Colorado Generations refers patients to Women’s Wellness Connection for free breast cancer and cervical cancer screenings. It also refers patients to the Colorado Colorectal Screening Program (CCSP)—another Amendment 35-funded project at CU Cancer Center, which through June 2011 had screened more than 13,000 Coloradans at 65 community health clinics and detected 112 cancers. “The program saves millions in medical costs by preventing colorectal cancer,” says Andrea Dwyer, CCSP Program Manager. “And you can’t put a price tag on the lives saved by those whose cancers were caught early or completely prevented.” With the loss of Amendment 35 money, the CCSP had to cut way back. Now the money has returned. “We were awarded nearly $3 million dollars this year in the state’s competitive grants program to rebuild the program infrastructure and screen several thousand people.” Amendment 35 money goes up, cancer goes down. Byers, Bunn, Levinson, Lowery, Dwyer and their CU Cancer Center colleagues hope that 2012 and 2013 are only the start.
LY NN C LARK
At the same time, Byers and Cancer Center colleague Paul Bunn, MD, joined the American Cancer Society’s effort to encourage state legislatures to preserve Amendment 35 money. Their efforts worked. Today, Colorado’s economy is recovering and Amendment 35 funding is being restored. In fiscal year 2012-2013, the state of Colorado predicts it will receive approximately $140 million in tax revenue from Amendment 35—about $46 million of which will be available to agencies working to prevent cancer—agencies like CU Cancer Center.
In addition to funding tobacco cessation and education programs, Amendment 35 sets aside money for research and treatment grants. Jan Lowery, PhD, MPH, CU Cancer Center investigator and assistant professor of epidemiology at the Colorado School of Public Health, is benefitting from one of these grants—and her work could soon benefit all Colorado residents. Lowery’s project, called “Colorado Generations” (for which she teamed up with Metro Community Provider Network and Plains Medical Center), is all about maximizing thin resources. Who should undergo costly advanced cancer screening? Well, the people who are at the greatest risk of developing the diseases. “It’s critical that we identify people who are at risk for here ditary cancer because their risk for developing cancer may be as high as 80 percent,” Lowery says. “This project will help clinics identify their patients that, due to their family history, are at increased risk for cancer and in need of cancer screening.”

NEW “PINK LIFE SAVER” HITS THE STREETS, PROVIDES BREAST CANCER SCREENINGS The top two reasons women don’t get annual mammograms are time and convenience. In an effort to overcome those excuses, University of Colorado Hospital, CU Cancer Center’s patient care partner, has created a mobile mammography coach named “The Pink Life Saver.” The Pink Life Saver was unveiled to the public for the first time on October 16 at the annual Men for the Cure event. Funds raised by Men for the Cure, along with money donated by King Soopers, paid for the unit, which is fully equipped to provide breast cancer screenings to women around the metro Denver area. Patients are able to schedule appointments for screenings in The Pink Life Saver, as the unit travels to UCH clinics and The Little Clinic at select King Soopers stores, one day a week. If the service is successful, the hospital plans to expand it to corporate clients. To find out where The Pink Life Saver is going to be or to schedule an appointment, call 720-848-1030.
