• Patients must not have an elevated PSA level as the only evidence of disease. While castrated, the patients should have rising PSA on two consecutive measurements at least 1 week apart. The confirmatory PSA must be obtained within 1 week prior to study registration and should be >10ng/ml.
• Patients with bone metastases only (i.e., lacking soft-tissue disease) must have a PSA level of > 10 ng/ml. Patients with soft tissue metastases and /or visceral disease must have either measurable disease or a PSA level of > 10 ng/ml.
• Radiological evidence of hydronephrosis will not by itself constitute evidence of metastatic disease.
• Patients must have had prior treatment with bilateral orchiectomy or other primary hormonal therapy (e.g., estrogen therapy, LHRH analog + flutamide, etc.) with evidence of treatment failure.

NOTE: Patients who have not undergone bilateral orchiectomy must continue LHRH agonist therapy (e.g., depot leuprolide or goserelin) while receiving this protocol therapy.

• For patients previously treated with flutamide (Eulexin), nilutamide (Nilandron), or bicalutamide (Casodex): Patients must have discontinued flutamide or nilutamide < 4 weeks and for bicalutamide 6 weeks prior to registration.

• Patients must have recovered from all toxicities due to prior treatment for prostate cancer prior to receiving this protocol treatment.
• Patients must have adequate bone marrow function: (WBC > 4000/ mm3, granulocytes > 2000/ mm3, platelet count > 100,000/mm3, and Hemoglobin > 8.0 g/dl < 4 weeks prior to participate in this study.
• Patients must have the following chemistry values < 4 weeks prior to participate in this study:
• Bilirubin < 1.5 mg/dl
• Transaminases (SGOT and/or SGPT) < 5 x institutional upper limit of normal (ULN)
• Creatinine < 2.0 mg/d. or creatinine clearance > 50 ml/min
• Alkaline phosphatase £ 5 x ULN
• Patients must have no active angina pectoris, or known heart disease of New York Heart Association Class III-IV. Patients must not have a history of myocardial infarction < 6 months prior to the study participation.
• Patients with a history of prior malignancy are eligible provided they were treated with curative intent and have been free of disease for the time period considered appropriate for the specific cancer.
• No serious concurrent medical illness or active infection should be present which would jeopardize the ability of the patient to receive the chemotherapy outlined in this protocol with reasonable safety.
• Sexually active patients must use an accepted and effective method of contraception while receiving protocol treatment.
• Patients must have a Karnofsky Performance Scale (KPS) score over 50. (Equaling ECOG Performance Scale of 0, 1, or 2).
• Age > 18 years.
