The Effect of Neoadjuvant DMPA on Glandular Cellularity in Women Awaiting Hysterectomy

Summary

Objective: To compare pre- and post-treatment glandular cellularity in women with complex atypical hyperplasia or grade 1-2 endometrial adenocarcinoma who are treated with intramuscular depot medroxyprogesterone acetate (DMPA) versus placebo injection prior to hysterectomy. The secondary objective is to compare various other outcomes including molecular, histologic, pathologic and clinical endpoints in women treated with DMPA versus placebo prior to hysterectomy. Hypothesis: Patients treated with DMPA will have significantly decreased glandular cellularity post-treatment when compared to patients treated with placebo injection. Patients treated with DMPA will exhibit previously described changes in molecular tumor marker expression patterns and other characteristic histologic changes. Patients treated with DMPA will report less bothersome vaginal bleeding prior to surgery when compared to patients treated with placebo injection. Study Design: Double blinded randomized controlled trial Population: Women being treated at the Women and Infants Program in Women's Oncology who have a biopsy-proven diagnosis of complex atypical hyperplasia or grade 1-2 endometrial adenocarcinoma with disease clinically confined to the uterus, with a plan to undergo hysterectomy. Study Period: February 2015 to June 2016
