Brief Summary:
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.

Primary Outcome Measures :
  1. Cumulative incidence of treatment-related grade 2 or higher rectal bleeding. [ Time Frame: 2 years after completion of radiation therapy ]

Secondary Outcome Measures :
  1. Analyzation of quality of life [ Time Frame: After radiation: every 6 months for 3 years, then annually for 20 years ]
  2. Analysis of treatment-related morbidity [ Time Frame: Cumulative incidence up to 20 years after completion of radiation therapy ]
  3. Analysis of disease control [ Time Frame: Cumulative incidence up to 20 years after completion of radiation therapy ]
    Proportion of patients with disease control after completion of treatment

  4. Analysis of overall survival [ Time Frame: Cumulative incidence up to 20 years after completion of radiation therapy ]
    Proportion of patients alive after completion of treatment
