Résumé
Date de début de l'étude : 1 novembre 2004
Date à laquelle le premier participant a commencé l'étude.OBJECTIVES: * Compare 1-year mammographic density in premenopausal women at high risk for developing breast cancer treated with celecoxib vs placebo. * Compare 1-year proliferation of breast epithelial cells, as measured by Ki67 staining, in patients treated with these drugs. * Compare the expression of other biomarkers, including cyclo-oxygenase-2 (COX-2) enzyme and a marker of apoptosis, in breast tissue of patients treated with these drugs. * Compare 1-year plasma levels of insulin-like growth factor (IGF)-1, IGF binding protein-3, and prostaglandin E_2 in patients treated with these drugs. * Compare the toxicity of these drugs in these patients. OUTLINE: This is a randomized, placebo-controlled, double-blind, multicenter study. Patients are stratified according to risk category (lobular carcinoma in situ or ductal carcinoma in situ vs BRCA1/2 mutation AND any Gail risk vs Gail risk ≥1.7% but < 5% vs Gail risk ≥ 5%) and prior tamoxifen use (yes vs no). Patients are randomized to 1 of 2 treatment arms. * Celocoxib: Patients receive oral celecoxib twice daily. * Placebo: Patients receive oral placebo twice daily. In both arms, treatment continues for 12 months in the absence of unacceptable toxicity or diagnosis of cancer. Patients are followed at 1 month. PROJECTED ACCRUAL: A total of 100 patients (50 per treatment arm) will be accrued for this study.
