Summary
OBJECTIVES: * Compare the complete response rate in patients with high-grade squamous intraepithelial lesions of the cervix treated with celecoxib vs placebo. * Compare the toxicity of these drugs in these patients. * Determine, preliminarily, the effect of celecoxib on cyclooxygenase-2 expression and human papilloma virus expression in these patients. OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to high-grade squamous intraepithelial lesion status (cervical intraepithelial neoplasia \[CIN\] 2 vs CIN 3). Patients are randomized to 1 of 2 treatment arms. * Arm I: Patients receive oral celecoxib twice daily for 1 month. * Arm II: Patients receive oral placebo twice daily for 1 month. In both arms, treatment repeats monthly for 3 courses in the absence of disease progression or unacceptable toxicity. All patients then undergo loop electrosurgical excision procedure or cone biopsy to determine response. PROJECTED ACCRUAL: A total of 100 patients (50 per treatment arm) will be accrued for this study within 1-2 years.
