Recurrent Prostate Cancer
Stage I Prostate Cancer
Stage II Prostate Cancer
Stage III Prostate Cancer
Interventions Dietary Supplement: genistein
Other: placebo
Procedure: therapeutic conventional surgery
Phase Phase 2

Eligibility Ages Eligible: 18 Years
Genders Eligible:  Male
Accepts Healthy Volunteers:  No
  • Participants must have a pathologic diagnosis of prostate cancer within the past 6 months, have clinical stage T1-3 disease, PSA >= 10, Gleason score >= 8, and have elected to undergo radical prostatectomy; those found to have detectable circulating prostate cancer cells in the blood as detected by qRT-PCR for PSA will be eligible to proceed onto the treatment phase of the protocol; pathology slides used for diagnosis will be submitted to the SPORE tissue pathology core for review
