University of Florida
ClinicalTrials.gov Identifier:
NCT01368055
First received: June 1, 2011
Last updated: April 14, 2015

  Purpose

The purpose of this trial is to give a shorter course (5 ½-6 weeks) of proton radiation that has as little side effects on normal bladder and rectal tissues as the usual longer course (8 weeks) of proton radiation, without decreasing the chance of killing prostate cancer cells.
