Can a shorter, stronger radiation course beat standard therapy for High-Risk prostate cancer?

NCT ID NCT02303327

First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time

Summary

This phase 3 trial tests whether a shorter course of higher-dose radiation can match or improve upon standard pelvic radiation plus a brachytherapy boost for men with high-risk prostate cancer. Participants also receive hormone therapy for 28 months. The study compares side effects and cancer control between the two approaches.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
radiation therapy (external beam radiation therapy and high-dose-rate brachytherapy boost) plus androgen deprivation therapy
What this could lead to
If one approach proves safer or more effective, it could become a new standard treatment for high-risk prostate cancer, potentially reducing side effects or improving cancer control.
What could go wrong
This is a phase 3 trial, but results may not show a clear advantage for either arm. Both treatments carry risks of urinary, bowel, and sexual side effects from radiation.
