NCT ID NCT01950351
First seen Jan 05, 2026 · Last updated Jun 23, 2026 · Updated 30 times
Summary
This phase II trial is testing a shorter course of proton beam radiation (hypofractionated) in 241 men with early-stage prostate cancer that hasn't spread. The goal is to see if this precise radiation can kill cancer cells while causing fewer bowel and bladder side effects compared to standard radiation. Researchers are tracking side effects and quality of life over time.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Proton beam radiation therapy
What this could lead to
If successful, this could offer a more precise, shorter course of radiation for prostate cancer with fewer bowel side effects.
What could go wrong
This is a mid-stage trial with 241 participants, so results are not yet definitive. There is still a risk of side effects, and the approach may not work for all patients.
