Smarter radiation aims to cut side effects in prostate cancer relapse

NCT ID NCT07515651

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a personalized radiation approach for men whose prostate cancer has returned after surgery. Using PSMA PET scans, doctors will give higher radiation doses to active cancer spots and lower doses to healthy areas, all in just 5 treatments over two weeks. The goal is to reduce side effects while keeping the cancer under control. Fifty participants will be followed for five years to track side effects and cancer recurrence.

What this could mean

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

Active substance

Image-guided radiotherapy (SBRT) with PSMA PET-based dose adjustment

What this could lead to

If successful, this approach could reduce treatment side effects while maintaining high cure rates for prostate cancer that has returned after surgery.

What could go wrong

This is a small, early-phase trial (50 participants) without a comparison group, so results may not apply broadly. There is also a risk that lowering radiation to some areas might allow cancer to return.
