Alternate Title

Celecoxib in Treating Postmenopausal Women Who Are Undergoing Surgery for Invasive Breast Cancer

Basic Trial Information

Objectives

Primary

1. Determine whether celecoxib suppresses aromatase activity in postmenopausal women with invasive breast cancer planning to undergo surgery.

Secondary

1. Correlate celecoxib-mediated inhibition of aromatase activity with levels of cyclooxygenase (COX)-2 and HER-2/neu and estrogen receptor status in these patients.
2. Determine the effect of this drug on histology, Ki67, RNA expression profile by microarray analysis, PI3-K, AKT and ERK1/2 MAP kinase activities, and PGE₂ levels in these patients.
3. Determine whether any observed biological effect of this drug is dose-dependent in these patients.
4. Identify collateral targets (COX-2-independent) of this drug in these patients.

Chemotherapy

• More than 3 months since prior chemotherapy

Endocrine therapy

• More than 2 weeks since prior hormone replacement therapy
• More than 2 weeks since prior tamoxifen

Expected Enrollment

A total of 75 patients (25 per treatment arm) will be accrued for this study within 2-3 years.

Outline

This is a randomized study. Patients are randomized to 1 of 3 treatment arms.

• Arm I: Patients receive oral celecoxib twice daily for 1-3 weeks (according to the duration between biopsy and surgery) in the absence of unacceptable toxicity.
• Arm II: Patients receive a higher dose of oral celecoxib as in arm I.
• Arm III: Patients do not receive treatment.

All patients undergo definitive surgery.
