RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.
- Determine the therapeutic efficacy of nitrocamptothecin in patients with metastatic, hormone refractory prostate cancer.
- Determine time to disease progression and duration of response in this patient population as a result of this treatment regimen.
- Determine the safety, tolerance, and toxicity of this treatment regimen in these patients.
OUTLINE: Patients receive nitrocamptothecin orally daily for 5 consecutive days each week for 3 consecutive weeks. Treatment continues every 4 weeks in the absence of disease progression or unacceptable toxicity.
Patients are followed every 3 months until evidence of progression or relapse for a maximum of 2 years from the date of registration.
PROJECTED ACCRUAL: A total of 22-46 patients will be accrued for this study over 2 years.
Primary Purpose: Treatment

A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
Tumors or cancer of the PROSTATE.
