Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
