Intermediate Risk prostate cancer as determined by the following:

  • Gleason sum of 7; PSA less than 10.1 ng/ml; Stage T2a or less
  • Gleason sum 6 or less; PSA >10.0 and < 20.1ng/ml; Stage T2a or less
  • Gleason sum 6 or less; PSA < 10.1; Stage T2b

High risk prostate cancer as determined by the following:

  • Any Gleason Sum; PSA greater than 20 ng/ml; Stage T2c or less
  • Gleason Sum > 7; Any PSA; Stage T2c or less
  • Any Gleason Sum; Any PSA; Stage T2c
  • Any two or three intermediate risk factor

Exclusion Criteria:

  • Lymph node involvement (N1)
  • Evidence of distant metastases (M1)
  • Any hormonal blockade or therapy that:

    • Has persisted for more than 6 months by time of protocol screening; OR
    • Is ongoing within 3 months of study enrollment
  • Radical surgery for carcinoma of the prostate
  • Prior pelvic radiation
  • Previous or concurrent cancers other than basal, in situ, or squamous cell skin cancers unless disease-free for ≥ 5 years
  • Major medical or psychiatric illness, which in the investigator's opinion, would prevent completion of treatment and would interfere with follow-up
