METHODOLOGY
ABSTRACT •
•
•
Background- Uterine fibroids are one of the commonly faced gynaecological problems in women today. By the latest report released by the United Nations, in the world of 3.8 billion women, more than 70% of them have a lifetime risk of facing it. In India, approximately 60% of the women have uterine fibroids by the age of 50, and it is increasing exponentially year by year.
Surgical methods: Hysterectomy, hysteroscopic myomectomy, Magnetic Resonance Guided Focused Ultrasound (MRgFUS), Laparoscopic myomectomy, Uterine artery embolization etc. Non-surgical methods: 1. Gonadotropin-releasing hormone (GnRH) 2. Selective progesterone receptor modulator (SPRM)
Strategy- Research papers on Uterine fibroids were studied from the National Centre for Biotechnology Information. Wide range of papers from 2010-2020 were taken to study all the developments and the progress in the field of Uterine Fibroids from which we identified the research gaps and the scope of research. Results- There are advancements in the treatment of uterine fibroids past decade in both surgical and nonsurgical methods, yet there are lot of complications and unavoidable side effects that put women in both physical and mental trauma. Therefore we came up with a hypothesis which can not only cure the fibroids completely but can also avoid the side effects which prevail later. We plan on introducing nano carrier with small molecules or drugs in the form of intrauterine implants or injectable products which can directly target the fibroids in the uterus.
•
Conclusion- Nano carrier can be a new prospect for treatment in uterine fibroids as it will focus on selective eradication. Yet there is a broad range of research that has to go into it.
• Nanotechnology can be a possible approach for the treatment of uterine fibroids. Nanomedicine is used in the treatment of many other diseases such as cancer, cardiac diseases, etc. • Using the same idea we came up with a hypothesis, we know that uterine fibroids are related to the secretion of excessive hormones such as progesterone and estrogen. • We plan on introducing a nano carrier with a drug inside that can be inserted intra-vaginally or injected intravenously injections. These nanocarriers that carry the drugs inside them which is used to stop the bleeding and also shrink the fibroids. • These drugs will be engineered to specifically bind to the receptors of the fibroids to which the hormones such as progesterone and estrogen bind and lead to fibroids formation. • These drugs inhibit the receptors and therefore the hormones can not bind to them. These drugs can stop the bleeding and shrink the fibroids. • This method focuses on selective eradication and will not cause any side effects like the hormonal treatments present today for the treatment of uterine fibroids
Past decade there have been advancements in the treatment of uterine fibroids. Many surgical and non-surgical methods have been introduced
Rationale- Despite being one of the major concerns faced by women today, the growth and pathogenesis of these fibroids are not clearly understood. The idea is to focus on a new treatment approach which can not only cure uterine fibroids permanently but also will have no side effects.

RESULTS
Despite all the advancements in the treatments present today, they all cause severe side effects such as infertility, the hormonal treatments if used more than 6 months cause hypoestrogenism and osteoporosis in women [6]. This brings the need to develop a new treatment approach that can tackle all the side effects faced by the existing treatment methodologies.
INTRODUCTION •
Uterine fibroids or leiomyomas are benign tumours which originate in the myometrium smooth muscles of the uterus and one of the most frequently faced gynecological problems in women today.
•
There are three types of uterine fibroids; intramural fibroids that grow within the uterus wall, submucosal fibroids which are present in the uterine cavity and subserosal fibroids which are present outside the uterus.
•
These tumors vary in size from a few millimetres to massive growth in the uterine wall. Symptoms of these uterine fibroids depend on the region where the fibroids are present, but 80% of the women who have uterine fibroids experience no symptoms and it is usually discovered only during pelvic examination or ultrasound [1].
•
Fibroids are related to the hormonal status in the body; therefore, occur in women in their reproductive age till menopause is reached [4]. Uterine fibroids have shown similarity to the myometrial cells during pregnancy [5]. Studies have confirmed that myometrial stem cells have been found among the myometrial cells [3]. These stem cells have been found to have characteristics of a tumour initiation, which causes cell proliferation and tumour growth in fibroids [2].

CONCLUSION •
The advancements in the research of uterine fibroids have expanded our knowledge on the biology of the fibroids to an extent. Yet growth and pathogenesis are not completely understood. There has been a significant advancement in the treatment procedure past decade in uterine fibroids which has introduced us to non-invasive procedures. Now we need to focus on the non-surgical treatments, which are effective in the long term and also can reduce the side effects extensively. Further, there is a need for the determination of early intervention and also the risk factors. In addition, a new approach to the treatment of uterine fibroids is required. The use of nanomedicine can be a possible approach for uterine fibroids
