Pathologically (histologically or cytologically) proven diagnosis of prostatic adenocarcinoma within 180 days of registration at moderate to high risk for recurrence
History/physical examination (to include at a minimum digital rectal examination of the prostate and examination of the skeletal system and abdomen) within 90 days prior to registration.
Clinically negative lymph nodes as established by imaging (pelvic ± abdominal CT or MRI), (but not by nodal sampling, or dissection) within 90 days prior to registration.
Patients with lymph nodes equivocal or questionable by imaging are eligible if the nodes are ≤ 2.0 cm.
No evidence of bone metastases (M0) on bone scan within 90 days prior to registration.
Equivocal bone scan findings are allowed if plain films (or CT or MRI) are negative for metastasis.
Baseline serum PSA value performed with an FDA-approved assay (e.g., Abbott, Hybritech) within 12 weeks (90 days) prior to registration.
Study entry PSA should not be obtained during the following time frames: (1) 10-day period following prostate biopsy; (2) following initiation of hormonal therapy; (3) within 30 days after discontinuation of finasteride; (4) within 90 days after discontinuation of dutasteride.
