Study Details

Brief summary:

This randomized phase III trial studies short course vaginal cuff brachytherapy to see how well it works compared with standard of care vaginal cuff brachytherapy in treating participants with stage I-II endometrial cancer. Short course vaginal cuff brachytherapy, also known as internal radiation therapy, uses (over a shorter period) radioactive material placed directly into or near a tumor in the upper portion of the vagina to kill tumor cells.

After completion of cohort 1 (108 participants), the protocol was expended to add a second cohort of 80 additional participants, and re-opened study recruitment.
