You may be eligible if

• DISEASE CHARACTERISTICS:
• Histologically confirmed adenocarcinoma of the prostate
• * Metastatic disease (N1 and/or M1)

• * Progression of measurable disease
• * Prior radiotherapy allowed provided radiotherapy was completed ≥ 2 months ago and lesion progressed since radiotherapy
• * Progression of nonmeasurable disease
• * Prior radiotherapy within the past 2 months allowed, but disease is considered nonmeasurable
• * Rising prostate-specific antigen (PSA) after \> 2 courses of chemotherapy OR within 6 months of last chemotherapy dose
• * Rising PSA defined as at least 2 consecutive rises in PSA to be documented over a reference value (measure 1)
• PSA ≥ 5 ng/mL
• Surgical or medical castration required
• * Castration using luteinizing hormone-releasing hormone agonist (leuprolide acetate or goserelin) or antagonist (abarelix) should not be interrupted
