Minimally Invasive Compared With Open Hysterectomy in High-Risk Endometrial Cancer.

Objective: To compare disease-free survival between minimally invasive surgery and open surgery in patients with high-risk endometrial cancer.

Methods: We conducted a multicentric, propensity-matched study of patients with high-risk endometrial cancer who underwent hysterectomy, bilateral salpingo-oophorectomy, and staging between January 1999 and June 2016 at two centers. High-risk endometrial cancer included grade 3 endometrioid, serous, clear cell, undifferentiated carcinoma or carcinosarcoma with any myometrial invasion.
