Brief Summary: RATIONALE Androgens can stimulate the growth of prostate cancer cells Hormone therapy using toremifene may fight prostate cancer by reducing the production of androgens

PURPOSE Randomized phase II trial to study the effectiveness of toremifene followed by radical prostatectomy in treating patients who have stage I or stage II prostate cancer
Detailed Description: OBJECTIVES

Compare the percent of high-grade prostatic intraepithelial neoplasia HGPIN present in the radical prostatectomy tissue excluding the luminal area of patients with stage I or II adenocarcinoma of the prostate treated with toremifene vs observation alone followed by radical prostatectomy
Compare the absolute and relative changes in HGPIN in patients treated with toremifene vs observation alone
Compare biomarkers including DNA ploidy and nuclear morphology Ki67 and MIB-1 expression bcl-2 expression frequency of cells expressing apoptotic bodies microvessel density and intraprostatic testosterone dihydrotestosterone DHT and estradiol in the radical prostatectomy tissue of patients treated with toremifene vs observation alone
Compare changes from baseline in serum biomarkers particularly PSA and hormone profiles testosterone DHT androstenedione dehydroepiandrosterone androstanediol-glucuronide estradiol and sex hormone binding globulin in patients treated with toremifene vs observation alone
Compare the safety of toremifene in these patients
Determine the relationships among pairs of biomarkers biomarker changes and outcome measures including toxicity of toremifene and posttreatment HGPIN in these patients
Determine the relationship between HGPIN or biomarker responses and antiandrogen germline CAG repeat length polymorphism in patients treated with toremifene
Compare the tumor volume margin status and pT stage in patients treated with toremifene vs observation alone

OUTLINE This is a randomized open-label multicenter study Patients are stratified according to participating center and baseline high-grade prostatic intraepithelial neoplasia none vs more than 0 up to 10 vs more than 10 Patients are randomized to 1 of 2 treatment arms

Arm I Patients receive oral toremifene daily for 3-6 weeks in the absence of unacceptable toxicity
Arm II Patients undergo observation alone Patients in both arms then undergo radical prostatectomy

PROJECTED ACCRUAL A total of 78 patients 52 for arm I 26 for arm II will be accrued for this study at a rate of 6-7 patients per month
