Eligibility Criteria Expand/Collapse

Pt must have a histologic diagnosis of adenocarcinoma of the prostate and be considered to have clinically localized disease (Stage T1-T3, N0, M0) and be considered operable for cure. Pts must have had a radical prostatectomy (RP) w/in 120 days prior to reg and fulfill one or more of the following: pathologic Gleason's sum of greater than or equal to 8; pT3b (seminal vesicle) or pT4 or N1; Gleason's sum of 7 and positive margin; or preop PSA of > 15 ng/ml or biopsy Gleason > 7 or PSA > 10 ng/ml and biopsy Gleason > 6. Serum testosterone must be obtained w/in 28 days prior to registration. Pt must have a PS of 0-1. Prior neoadj therapy of less than/equal to 4 mos prior to RP is allowed provided pt fulfilled clinical eligibility prior to hormonal treatment. Pts may have started hormonal therapy post-prostatectomy but prior to reg to this study. No other therapy aimed at the tx of this diagnosis may have been given or may be planned while pt is rec'g protocol tx. Use of low dose megace for tx of hot flashes is allowed. Pts must not have rec'd prior RT. If physician wishes to admin RT, Pt should be registered 1st and then optional RT given on protocol.

Pts with PSA at clinical diagnosis greater than/equal 20 ng/ml must have bone scan not suggestive of metastatic disease w/in 180 days prior to reg. Pts w/symptoms of distant mets must have appropriate tests to evaluate for met disease w/in 56 days prior to reg. Pts with confirmed distant mets are ineligible. Pts must have baseline EKG w/in 42 days prior to reg. Pts w/history of cardiac disease (CHF) are ineligible unless their disease is well-controlled and they have LVEF greater than/equal to 50% by MUGA or 2-d echo w/in 42 days prior to reg. Pts known to be HIV + are not eligible.
