研究概览
简要总结
RATIONALE: Genistein may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
PURPOSE: This randomized phase II trial is studying how well genistein works in treating patients with prostate cancer.
详细描述
PRIMARY OBJECTIVES:
I. Determine whether genistein treatment will decrease the number of circulating prostate cells (CPCs) in the peripheral blood as measured by qRT-PCR for PSA performed on RNA extracted from peripheral blood mononuclear cells (PBMNCs).
SECONDARY OBJECTIVES:
I. Determine the natural history of circulating prostate cells (CPCs) in a cohort of subjects prior to and post radical prostatectomy.
II. Compare the measurement of PSA between three separate methods: in CPCs by qRT-PCR, in serum by the standard clinical chemistry assay (i.e., ELISA), and in plasma and serum by the nano-PSA assay.
