NRG Oncology Protocol Development Template for Radiation Therapy — Gynecological Cancer: Endometrial Cancer (post-operative treatment after hysterectomy)

The NRG Oncology template for the radiation section of a post-operative endometrial cancer trial. It covers supine or prone setup, vaginal apex markers, full- and empty-bladder scans fused to build the vaginal internal target volume, nodal CTV guidance, standard structure names, example prescriptions (45 or 50.4 Gy), example vaginal cuff brachytherapy schedules alone or as a boost, and per-protocol and variation-acceptable organ goals. For cuff brachytherapy it asks for dose points along the cylinder and verification of the dome position rather than volumetric organ limits. Its values are examples meant to be edited for each trial.

How an NRG trial would write post-operative pelvic radiation for endometrial cancer, including the vaginal ITV, organ goals and vaginal cuff brachytherapy schedules.
