Is this trial a fit for you?

Likely a good fit

Ideal candidates are female adults aged 18 and older with a BMI of 35 or higher and a diagnosis of grade 1 endometrial carcinoma or EIN.

Probably not a fit

Patients with a BMI below 35, those with more advanced cancer diagnoses, or contraindications to bariatric surgery will not benefit from this study.

What this trial studies

This study aims to evaluate the feasibility of a streamlined referral process for obese patients diagnosed with endometrial carcinoma or endometrial intraepithelial neoplasia (EIN) to undergo concurrent laparoscopic hysterectomy and weight loss surgery. The goal is to perform both surgeries within 8 to 12 weeks of the initial appointment with a gynecologic oncologist, depending on the diagnosis. By addressing obesity, which is a significant risk factor for endometrial cancer, the study seeks to improve patient outcomes and reduce obesity-related health issues. Approximately 30 patients will be enrolled at Brigham and Women's Hospital to assess the safety and effectiveness of this combined surgical approach.

Why it matters

Potential benefit: If successful, this approach could lead to improved survival rates and reduced obesity-related health complications for patients with endometrial cancer.

How similar studies have gone: While the combined approach has been performed previously without increased complications, this is the first formal study assessing its feasibility and effectiveness.
