Summary
Brief summary (as posted)
The study is to examine a moderate hypofractionation regimen of proton beam therapy for high risk or unfavorable intermediate risk prostate cancer. The prostate and seminal vesicles are treated with 6750 centigray (RBE) in 25 fractions (i.e. 270 centigray/fraction), while the regional pelvic nodes receive 4500 centigray (RBE) in 25 fractions (i.e. 180 centigray/fraction) simultaneously. The overall treatment time is 5 weeks.

Primary outcomes (1)
- measure
- Late Grade ≥ 3 Gastrointestinal (GI) and Genitourinary (GU) Toxicity of Interest, Using the CTCAE v4.0
- timeFrame
- Between 3 months and 24 months post proton beam therapy
- description
- Toxicity will be defined as an adverse event possibly, probably, or definitely related to proton beam therapy. A late GI or GU toxicity will be defined as a GI or GU toxicity that occurs between 3 months and 2 years from the completion of proton beam therapy. All patients meeting the eligibility criteria who have signed a consent form and have begun treatment will be evaluable for late toxicity, with the exception of patients determined to be a major violation.
