Weight loss program may help women avoid hysterectomy and preserve fertility
NCT ID NCT05903131
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a behavioral weight loss program to standard hormone therapy helps premenopausal women with obesity and early endometrial cancer or precancer keep their uterus and fertility. About 96 women will receive either the weight loss program plus hormone therapy or hormone therapy alone. The goal is to see if weight loss can improve treatment success and reduce the risk of cancer coming back.

Inclusion Criteria: * Diagnosis of histologically confirmed complex atypical endometrial hyperplasia (AEH) or grade 1 endometrial cancer. * Patients with a previous diagnosis of AEH or grade 1 endometrial cancer who are already being followed with conservative management with oral or LNG-IUD progestin therapy are eligible. * For patients with a previous diagnosis of AEH or grade 1 endometrial cancer who have been placed on progestin prior to study entry, the duration of IUD or oral progestin use prior to trial entry should be documented. * Premenopausal woman with a uterus. * ECOG performance status of 0-2. * At least 18 years of age and no more than 45 years of age. * Undergoing uterine-sparing management (e.g. due to interest in fertility preservation, interest in uterine preservation, provider recommendation, or other reason). * BMI ≥ 30 kg/m\^2. * Prior or current receipt of progestin is allowed as above. Willingness to undergo placement of LNG-IUD at the time of study entry. * Ability to understand and willingness to sign an IRB approved written informed consent document. Exclusion Criteria: * Current, active treatment for any malignant neoplasm with chemotherapy or radiation. * Pregnant and/or breastfeeding. Participants must have a negative urine or serum pregnancy test during screening window and within 7 days prior to LNG-IUD insertion.
