Hypofractionated Proton Radiation Therapy for Low and Intermediate Risk Prostate Cancer (PR07)

This study is currently recruiting participants. (see Contacts and Locations)
Verified April 2015 by University of Florida
Information provided by (Responsible Party):
University of Florida
ClinicalTrials.gov Identifier:
First received: June 1, 2011
Last updated: April 14, 2015

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.
