MRI-Guided radiation aims to cut side effects in prostate cancer treatment
NCT ID NCT03778112
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests whether using advanced MRI scans to guide radiation therapy can reduce side effects for men with localized prostate cancer. Depending on their MRI results, patients receive either a short course of radiation or a longer treatment with a targeted boost to visible tumors. The trial tracks urinary and bowel side effects 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
- Radiation therapy (SBRT and IMRT)
- What this could lead to
- If successful, this approach could offer a more personalized radiation plan that reduces side effects while effectively treating prostate cancer.
- What could go wrong
- This is a small, early-phase study with only 54 participants, so results may not apply to everyone. There is still a risk of radiation-related side effects.
