  • Prostate Cancer


RATIONALE: Drugs used in chemotherapy, such as eflornithine, work in different ways to stop tumor cells from dividing so they stop growing or die. Androgens can stimulate the growth of prostate cancer cells. Drugs used in hormone therapy, such as bicalutamide, may fight prostate cancer by stopping the adrenal glands from producing androgens. Combining eflornithine with bicalutamide may kill more tumor cells. PURPOSE: Randomized phase II trial to compare the effectiveness of neoadjuvant eflornithine and bicalutamide with that of eflornithine alone, bicalutamide alone, and no neoadjuvant therapy in treating patients who are undergoing brachytherapy or radical prostatectomy for localized prostate cancer.

Study summary:

OBJECTIVES: - Compare levels of polyamine spermine, polyamine putrescine, and spermidine in patients with localized prostate cancer undergoing brachytherapy or radical prostatectomy and treated with neoadjuvant eflornithine and bicalutamide vs eflornithine alone vs bicalutamide alone vs no neoadjuvant therapy. - Compare the expression of surrogate biomarkers (i.e., serum prostate-specific antigen, tissue levels of proliferating cell nuclear antigen, Ki67, and TGF-alpha, apoptosis assays [ICH-PARP and TUNEL], and cytomorphometric indices) in patients treated with these regimens. - Compare the toxicity of these regimens in these patients. OUTLINE: This is a randomized, double-blind, placebo-controlled study. Patients are stratified according to Gleason score (< 7 vs ≥ 7). Patients are randomized to 1 of 4 treatment arms. - Arm I: Patients receive oral eflornithine and oral bicalutamide once daily. - Arm II: Patients receive oral eflornithine and oral bicalutamide placebo once daily. - Arm III: Patients receive oral eflornithine placebo and oral bicalutamide once daily. - Arm IV: Patients receive oral eflornithine placebo and oral bicalutamide placebo once daily. In all arms, treatment continues for 28 days in the absence of unacceptable toxicity. Patients then undergo either prostatectomy or brachytherapy, as determined by the patient, on day 29. Patients are followed at 4 weeks. PROJECTED ACCRUAL: A total of 44 patients (11 per treatment arm) will be accrued for this study within 11 months.
