Could less radiation be better for prostate cancer?

NCT ID NCT06638541

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study is testing whether giving a lower dose of radiation in just two sessions can reduce side effects for men with intermediate-risk prostate cancer. All participants will be treated on a special MRI-guided machine (MR-Linac) that adapts the radiation daily. The main goal is to see if the lower dose causes fewer urinary problems while still keeping the cancer under control.

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

Active substance
radiation therapy
What this could lead to
If successful, this could show that a lower radiation dose is just as effective but causes fewer urinary side effects for men with intermediate-risk prostate cancer.
What could go wrong
This is a small, early-phase trial with only 54 participants, so results may not apply to all patients. Lowering the dose might also reduce cancer control, though the study will monitor PSA levels closely.
