RATIONALE: Studying samples of blood, urine, and tissue from patients with cancer in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. It may also help doctors learn how genistein or placebo works in patients with bladder cancer.
PURPOSE: This randomized phase II trial is studying genistein or placebo to compare how they work in patients who are undergoing surgery for bladder cancer.

OBJECTIVES:
Primary
Secondary
OUTLINE: This is a randomized, placebo-controlled, multicenter study. Patients are stratified according to invasiveness of disease (non-invasive [stage Ta, Tis, or T1] vs invasive [stage T2, T3, or T4]). Patients are randomized to 1 of 3 treatment arms.
One day after completion of genistein or placebo, all patients undergo cystoscopic excision, transurethral resection of the bladder tumor, or cystectomy.
Patients undergo blood, urine, and tissue sample collection for pharmacogenomic, pharmacokinetic, and biomarker laboratory studies. Blood and urine samples are collected at baseline, after 1 week of treatment, and at the time of surgery for pharmacokinetic and urine biomarker (survivin and BLCA-4) studies. Pharmacogenomic studies (epidermal growth factor receptor [EGFR] polymorphisms and CYP3A 4/5 genotypes) are performed at baseline using blood samples. Tissue biomarker (EGFR polymorphism, EGFR mutations [EGFR vIII, exon 19-21], EGFR, phosphorylated EGFR, Ki67, activated caspase 3, Akt, P-Akt, MAP kinase, P-MAP kinase, COX-2, survivin, and BLCA4) studies using tumor tissue and adjacent and remote normal urothelium are performed at baseline and at the completion of treatment.
PROJECTED ACCRUAL: A total of 60 patients (20 per treatment arm) will be accrued for this study within 1 year.
