RATIONALE: Chemoprevention therapy is the use of certain drugs such as flutamide to try to prevent the development of cancer. Flutamide may be effective in the prevention of prostate cancer.

PURPOSE: Randomized clinical trial to study the effectiveness of flutamide in preventing prostate cancer in patients who have neoplasia of the prostate.

Condition Intervention
Prostate Cancer
Drug: flutamide

Study Type: Interventional
Study Design: Allocation: Randomized
Primary Purpose: Prevention
Official Title: Short-Term Chemoprevention Trial in Men With Prostatic Intraepithelial Neoplasia Using Flutamide as an Androgen Deprivation Agent

Study Start Date: August 2000
Primary Completion Date: September 2000 (Final data collection date for primary outcome measure)
Detailed Description:

OBJECTIVES: I. Determine the ability of flutamide to reduce the incidence of prostate cancer in patients with high grade prostatic intraepithelial neoplasia. II. Determine the effect of this regimen on a series of endpoint biomarkers in these patients. III. Assess the quality of life of these patients.

OUTLINE: This is a randomized, double blind, placebo controlled, multicenter study. Patients are stratified according to age (under 65 versus 65 and over), PSA (0-2.5 versus 2.6-4.0 versus 4.1-10 versus greater than 10 ng/mL), PIN (on one biopsy versus on two biopsies), and family history (prostate cancer in brother, father, or uncle versus no prostate cancer in these relatives). Patients are randomized to one of two treatment arms. Arm I: Patients receive oral flutamide once daily. Arm II: Patients receive an oral placebo once daily. Treatment continues for 1 year in the absence of disease progression or unacceptable toxicity. Quality of life is assessed before study, at 1, 6, and 12 months, and then annually therafter. Patients are followed annually for up to 10 years.

PROJECTED ACCRUAL: A total of 212 patients (106 per arm) will be accrued for this study in approximately 2 years.
