Study Details

Study Description

Brief Summary

The purpose of this study is to see what effects, good and/or bad, proton radiation, and/or conventional radiation and hormonal therapy (if applicable), has on prostate cancer that has already returned or the risk of prostate cancer returning.

Condition or Disease Intervention/Treatment Phase
  • Radiation: IMRT to 45 Gy; prostate bed proton boost of 21.6 CGE
  • Radiation: Proton (prostate bed) to 70.2 CGE
  • Radiation: IMRT to 45 Gy; proton boost to prostate bed to 25.2 CGE
  • Radiation: Proton to 66.6 CGE

Outcome Measures

Primary Outcome Measures

  1. The treatment-related rate of acute grade 3 gastrointestinal and genitourinary toxicity following treatment with proton based radiation therapy. [6 months after the end of radiation therapy]

Secondary Outcome Measures

  1. Collect and analyze quality of life, treatment-related morbidity, disease control and survival outcome parameters [After radiation: every 6 months for 3 years, then annually for 20 years]
