Radiation Therapy With or Without Bicalutamide for Recurrent pT3N0 Prostate Cancer After Radical Prostatectomy

Conditions for Patient Eligibility:

• The patient on entry will have no clinical evidence of disease by physical exam or by imaging studies. A positive ProstaScint scan alone without a confirmatory biopsy must not be used to exclude a patient. Eligible patients will be those who have undergone a radical prostatectomy (either retropubic or perineal) and pelvic lymphadenectomy (either open or laparoscopic) for carcinoma of the prostate, pathologic stage T3N0, or pT2 pN0 with positive inked resection margin, at least 12 weeks prior to study entry.
• Pathological T2 patients without positive margins, who are also pathologic N0 with prostatic fossa/anastamosis biopsy at the time of rising PSA documenting recurrent cancer, are eligible.
• At entry, the PSA must be between 0.2 and 4.0ng/ml, inclusive.
• A post-prostatectomy radioisotopic bone scan which was done within 16 weeks prior to entry must reveal no evidence of metastatic disease.
• Patient must be evaluated by both the radiation oncologist and the urologist prior to entry and judged to be a suitable candidate for radiation and hormonal therapy.
• Patient must have Karnofsky performance status >= 80.
• Patients must have a life expectancy in excess of 10 years.
• Patients must have, within 6 weeks prior to entry, a hemoglobin (Hgb) of >=10 gm, a white blood cell (WBC) count of >= 4000 cells/ml3, a platelet count of >= 100,000 cells/ml3, a serum bilirubin 4.0ng/ml.
• Patients with persistant urinary extravasation after prostatectomy.
• Patients who have been previously treated with any hormonal therapy after prostatectomy.
• Patients who have previously been treated with radiation therapy or biologic therapy for prostate cancer.
• Karnofsky performance status 4 weeks after randomization.
• Prior chemotherapy for any reason.
