• Patients must have a negative Computerized Tomography (CT) scan and Bone Scan for metastatic prostate cancer.
• Patients must have histopathological documentation of prostate cancer. Every attempt should be made to have slides and blocks reviewed at National Cancer Institute (NCI) Pathology laboratory. The review of pathology by the NCI will not delay enrollment.
• Patients must have progressive prostate cancer. Two consecutively rising PSAs above the nadir post-definitive therapy and an absolute value greater than 1.0 ng/ml separated by at least 2 weeks.

• Hematological eligibility parameters (within 2 weeks of starting therapy):

Granulocyte count greater than or equal to 1,000/mm^3. Platelet count greater than or equal to 75,000/mm^3.

- Biochemical eligibility parameters (within 2 weeks of starting therapy): If the creatinine is greater than 2.0 mg/dL obtain a 24 hour urine collection.

Creatinine clearance must be greater than 40 mL/min. Hepatic function:

bilirubin (total) less than or equal to 1 mg/dL upper limit of normal; Alanine aminotransferase (ALT) less than 2.5 times upper limit of normal.

• Exception: Patients with Clinical Gilbert's Syndrome may have total bilirubin less than or equal to 2.5 mg/dL.

• Patients with Rai Stage of Chronic Lymphocytic Leukemia (lymphocytosis only) will be eligible.

• Patients that have received leuprolide, diethylstilbestrol (DES), flutamide, bicalutamide, PC stands for prostate cancer and SPES is the Latin word for hope)PC-SPES, goserelin, cytotoxic chemotherapy, finasteride and/or nilutamide within the past year (or currently) are not eligible. Patients that received these agents for adjuvant or neoadjuvant therapy at the time of definitive therapy are eligible. Exception: Patients enrolled under late entry criteria, who have received leuprolide/goserelin within 3 months of starting study are eligible.
