Inclusion Criteria:
- Histologic diagnosis of carcinoma of the prostate within 6 months of entry without evidence of metastatic disease to the lymph nodes, bone or lung;
- Intermediate risk prostate cancer (that is, T1-2a, Gleason score <6, PSA 10.1-20.0 ng/ml; T2b-c Gleason <6, PSA ≤ 20.0 ng/ml; T1-2, Gleason 7, PSA ≤ 20.0 ng/ml).
