Clinical Trial Summary

To assess the feasibility of an expedited referral process for the obese endometrial cancer or EIN patient from her gynecologic oncologist to the Brigham Center for Metabolic and Bariatric Surgery (CMBS) in order to undergo concurrent weight loss surgery and hysterectomy within 8 weeks of first appointment with a gynecologic oncologist (or 12 weeks for EIN patients).

Description:

The most common risk factor for endometrial cancer is obesity. However, because early-stage endometrial cancer has a very high survival rate, patients more often suffer from long-term issues related to their weight, like heart disease, stroke, and diabetes. Weight loss surgery has been shown to help patients lose weight and also decrease their risk for obesity-related diseases.

This research study is a Feasibility Study. This is the first-time investigators are studying both 1) the referral process of patients with endometrial cancer to the Center for Metabolic and Bariatric Surgery without delaying curative treatment of endometrial cancer 2) the combined surgery of both hysterectomy and weight loss surgery. The combined surgery of hysterectomy and weight loss surgery has been performed both at this institution and others without increased complications, but it has not been formally studied.

Approximately 30 patients are expected to participate in this study at Brigham and Women's Hospital (BWH).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	proportion of patients who schedule an appointment and speak with a surgeon 1-2 weeks after enrollment	50% of the patients utilize the referral system and attend an initial consultation, it will be considered feasible	2 Weeks
Primary	proportion of patients who undergo the concurrent surgeries within 8 weeks of diagnosis (12 weeks for EIN patients)	concurrent surgery will be considered feasible if 50% (7-8 patients) of patients who undergo an initial consultation at the CMBS actually undergo concurrent surgery within 8 weeks of diagnosis (or 12 weeks for EIN).	up 12 weeks
Secondary	Safety of the concurrent surgeries	compare our safety outcomes with national complication rates for each individual surgery to assess the safety of the patient population	3 weeks

Secondary	Time under anesthesia	compare our safety outcomes with national complication rates for each individual surgery to assess the safety of the patient population	1 Day
Secondary	Total time in operating room	compare our safety outcomes with national complication rates for each individual surgery to assess the safety of the patient population	1 Day
Secondary	Postoperative weight loss	Paired t-test or Wilcoxon rank sum test will be used to compare pre- and post-surgical outcomes and survey responses	6 months, 1 year
