Summary

This study tested a shorter course of proton radiation (5 treatments over 2 weeks) for men with localized prostate cancer, compared to the usual 8 weeks. The goal was to see if this approach maintains quality of life and controls the cancer. 150 men with low- to intermediate-risk prostate cancer took part. The study focused on tracking side effects and cancer recurrence.
