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.

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.
