Clinical Trial Summary

RATIONALE: Genistein may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth.

PURPOSE: Phase II trial to study the effectiveness of genistein in treating patients with localized prostate cancer who are planning to undergo radical prostatectomy.


Clinical Trial Description

OBJECTIVES:

- Determine the toxicity of genistein in patients with localized prostate cancer treated with radical prostatectomy.

- Determine the decrease, if any, of prostate-specific antigen-positive cells in the operative field of patients treated with this drug.

- Determine the quality of life of patients treated with this drug.

OUTLINE: Patients receive 1 of 2 treatment regimens.

- Group A: Patients receive oral genistein once daily for 1-2 months, undergo radical prostatectomy, and then continue oral genistein once daily for 1-2 months afterward (for a total of 3 months of therapy).

- Group B: Patients undergo radical prostatectomy. Beginning 1 month after surgery, patients receive genistein as in arm I for 3 months.

Quality of life is assessed at baseline and at 1 and 3 months after surgery.

Patients are followed every 3 months.

PROJECTED ACCRUAL: A total of 88 patients (44 patients per treatment group) will be accrued for this study within 2 years. ;
