A Randomized Phase III Trial of Hypofractionated Post-Prostatectomy Radiation Therapy (HYPORT) Versus Conventional Post-Prostatectomy Radiation Therapy (COPORT)

NRG Oncology·interventional·Posted Sep 7, 2017·Updated May 20, 2026

In Brief

A Phase 3 clinical trial evaluating Hypofractionated Radiation Therapy, Laboratory Biomarker Analysis, and 2 other interventions for Prostate Adenocarcinoma and 3 related conditions. Completed, enrolled 296 participants across 241 sites in 3 countries.

Detailed Summary

This randomized phase III trial studies how well hypofractionated radiation therapy works compared to conventional radiation therapy after surgery in treating patients with prostate cancer. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Conventional radiation therapy uses high energy x-rays, gamma rays, neutrons, protons, or other sources to kill tumor cells and shrink tumors. It is not yet known whether giving hypofractionated radiation therapy or conventional radiation therapy after surgery may work better in treating patients with prostate cancer.
