The role of vaginal brachytherapy in stage I endometrial serous cancer: a systematic review.

Serous adenocarcinoma (uterine serous carcinoma - USC) is a rare and aggressive histologic subtype of endometrial cancer, with a high-rate of recurrence and poor prognosis. The adjuvant treatment for stage I patients is unclear. The purpose of this study was to evaluate the outcomes of stage I USC treated exclusively with chemotherapy plus vaginal brachytherapy (VBT).
