Study Summary

The purpose of this study is to compare the effects (good and bad) on patients with prostate cancer by comparing the standard dose of radiation therapy (44 treatments over 8½-9 weeks) with a higher daily dose of radiation (5 treatments over 1-2 weeks) to see if the effects of the treatments are similar or better.

Primary Outcome

The events for FFF will be the first occurrence of clinical failure (local recurrence, regional recurrence, or distant metastasis), biochemical failure by the Phoenix definition (PSA ≥ 2 ng/ml over the current nadir PSA),or the start of salvage therapy including androgen deprivation.
