University of Florida
  Purpose
The purpose of this trial is to give a shorter course (5 ½ weeks) of radiation that has as little side effects on normal bladder and rectal tissues as the usual longer course (8 weeks) of radiation, without decreasing the chance of killing prostate cancer cells.

Condition Intervention
Prostate Cancer Radiation: Low Risk Proton Radiation Radiation: Intermediate Risk Proton Radiation

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
