Brief Title: Genistein in Treating Patients With Localized Prostate Cancer Who Are Planning to Undergo Radical Prostatectomy
Official Title: A Phase II Study Of Genistein In Patients With Localized Prostate Cancer (Molecular Correlates of Soy In Humans)
Study ID: NCT00058266
Brief 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.
Detailed 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.
