New radiation technique aims to ease urinary problems in prostate cancer treatment
NCT ID NCT06825091
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if a newer, more precise type of radiation (adaptive SBRT) can cause fewer urinary problems than standard radiation for men with localized prostate cancer. About 320 men will be randomly assigned to one of the two radiation methods. The goal is to see if the newer approach improves quality of life while still controlling the cancer effectively.
