• Intermediate risk patients will be defined as:
  • PSA 10-20 ng/ml or
  • Gleason score = 7 or
  • Clinical stage T2b/T2c
  • Additionally, patients will be required to meet the following criteria:
• Age > or = to 18
• KPS > or = to 70
• Pre-treatment endorectal coil MRI or CT (MRI preferred) at MSKCC showing no definite evidence of radiographic T3, T4, or N1 disease
