High-risk surgical stage 1 endometrial cancer: outcomes with vault brachytherapy alone.

Objective: Prior to 1995, in our center, patients with surgically staged endometrial cancer with greater than 50% myoinvasion (FIGO 1C) were treated with vault brachytherapy and whole pelvis (WP) radiotherapy despite negative nodes. After October 1, 1995, these patients were treated with vault brachytherapy alone. The aim of this study was to ensure that the survival and recurrence rate had not changed.
