Proton beam aims to zap prostate cancer return with fewer side effects
NCT ID NCT00969111
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests proton radiation therapy for men with prostate cancer that has returned or is at risk of returning after prostate removal surgery. Researchers want to see if this precise type of radiation can control the cancer while causing fewer side effects than standard radiation. About 70 men will receive different doses of proton therapy depending on their risk level.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
proton radiation therapy
What this could lead to
If successful, this could offer a more precise radiation option for prostate cancer patients after surgery, potentially reducing side effects while controlling the disease.
What could go wrong
This is a small, early-phase study with only 70 participants, so results may not apply to everyone. Side effects like bowel or bladder issues are still possible.
