Bariatric Surgery Decreases Risk of Uterine Cancer
San Diego, CA - Researchers at the University of California, San Diego School of Medicine and Moores Cancer Center report that bariatric surgery resulting in dramatic weight loss in formerly severely obese women reduces the risk of endometrial cancer by 71 percent and as much as 81 percent if normal weight is maintained after surgery.
Published in the April issue of Gynecologic Oncology, the official publication of the Society of Gynecologic Oncology, the findings indicate obesity may be a modifiable risk factor for endometrial cancer, and bariatric surgery a viable option for eligible patients. They are based on a retrospective cohort study of 7,431,858 patients in the University HealthSystem Consortium database, which contains information from contributing academic medical centers in the United States and affiliated hospitals. Of this total, 103,797 patients had a history of bariatric surgery and 44,345 had a diagnosis of uterine malignancy.
“Estimating from various studies that looked at increasing BMI and endometrial cancer risk, a woman with a Body Mass Index (BMI) of 40 would have approximately eight times greater risk of endometrial cancer than someone with a BMI of 25,” said first author Kristy Ward, MD, the senior gynecologic oncology fellow in the Department of Reproductive Medicine at UC San Diego School of Medicine. “This risk likely continues to go up as BMI goes up.” Continue>
