Official Title
Bariatric Surgery for Fertility-Sparing Treatment of Atypical Hyperplasia and Grade 1 Cancer of the Endometrium
Brief Summary
A growing population of young women with obesity are developing atypical hyperplasia (pre-cancer) and endometrial cancer. Progestin is the standard treatment for women who wish to preserve fertility, but this approach does not address the underlying cause of endometrial cancer/atypical hyperplasia (obesity); thus response rates are low and recurrence rates are high. Significant weight loss by bariatric surgery, in combination with progestin therapy may result in greater and more durable response rates.
Detailed Description
The incidence of endometrial cancer is increasing at an alarming rate (2.6% per year). This trend parallels the rising rate of obesity, the most significant increasing risk factor for endometrial cancer. Young women with obesity and endometrial cancer or atypical hyperplasia who want to maintain their fertility and thus avoid hysterectomy are treated with progestin therapy, such as progestin intra-uterine device (pIUD). However, the pIUD achieves cancer regression in only 50-70% of women, and over 50% of initial responders will develop recurrence within two years. The effectiveness of the pIUD may be improved if the driver of endometrial cancer (obesity) was simultaneously addressed. Multiple epidemiologic studies have demonstrated that bariatric surgery reduces the risk of developing endometrial cancer. Our research aims to answer the question: "Is bariatric surgery in addition to the pIUD a feasible and acceptable option for young women with endometrial cancer/atypical hyperplasia who wish to maintain their childbearing potential compared to standard treatment of pIUD alone? This is a pilot randomized controlled trial to assess the feasibility of a full-scale randomized controlled trial. Eligible women will be identified and consented over a 21-month period, and participants will be randomized to bariatric surgery plus standard pIUD (intervention group) or to standard pIUD alone (non-intervention group) in a 1:1 fashion.
