  Purpose
The purpose of this study is to compare the toxicity of two new radiation schedules for the treatment of prostate cancer. Patients will be randomized to receive 5 treatments delivered every other day over 11 days, or once per week over 29 days. Both of these schedules are shorter than the standard treatment which is usually 39 treatments over 8 weeks.

Condition Intervention Phase
Prostatic Neoplasms Radiation: Image-guided radiotherapy Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Randomized Phase II Study of 2 Hypofractionated Radiotherapy Schedules for Low- and Intermediate-Risk Prostate Cancer
