Primary Outcome Measures:
  • Treatment-related morbidity [ Time Frame: yearly update greater than 20 years ]
    To determine if late Radiation Therapy Oncology Group (RTOG) >/= to Grade 3 treatment-related morbidity, which is no worse than that engendered by our current institutional standard with conventional fractionation, can be maintained in a hypofractionated schedule

Estimated Primary Completion Date: June 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Proton radiation therapy

As above
Other Name: Proton Radiation treatment

Detailed Description:
Radiation therapy has a long and established role in the curative treatment of organ-confined prostate cancer. However, the optimal radiation dose and treatment schedule remain unknown. The use of hypofractionation has a long and generally successful history in conformal proton beam therapy. Several reports detailing the efficacy and safety of hypofractionated conformal radiation therapy (with x-rays) of prostate cancer can be found in the literature. Hypofractionated conformal proton beam radiation therapy has become our institutional routine for the treatment of numerous solid tumors. The purpose of this study is to determine if a shortened overall treatment schedule will result in equivalent tumor control rates and no increased side effects as compared to our current institutional standard treatment of an equivalent dose given over a longer period of time.
