OBJECTIVES:

• To determine the safety and efficacy of four courses of neoadjuvant chemotherapy comprising docetaxel, capecitabine, and celecoxib followed by doxorubicin hydrochloride, cyclophosphamide, and celecoxib for the treatment of women with resectable stage II or III breast cancer.
• To determine the mRNA and protein levels of thyraidylate synthase (TS), thymidine phosphylase (TP), vascular endothelial growth factor (VEGF), Multi-Drug Resistance Protein 1 (MDR-1), cyclooxygenase-2 (COX-2), and matrix metalloproteinase-2 (MMP-2) in tumor tissue prior to and following treatment.
• To correlate baseline expression of TS, TP, VEGF, MDR, COX-2, and MMP-2 to tumor response measured by physical exam, breast MRI, breast ultrasound, mammography, and pathologic response.
• To determine if polymorphisms in the genes that encode those proteins also correlate with outcome, if a correlation is found between specific molecular markers and clinical outcome.

OUTLINE:

• Neoadjuvant chemotherapy: Patients receive docetaxel IV over 1 hour on days 1, 8, and 15, oral capecitabine twice daily on days 1-14, and oral celecoxib twice daily on days 1-21. Courses repeat every 3 weeks for 4 courses in the absence of disease progression or unacceptable toxicity.

Patients then receive doxorubicin hydrochloride IV and cyclophosphamide IV once daily on day 1, oral celecoxib twice daily on days 1-14, and filgrastim subcutaneously once daily on days 3-10. Courses repeat every 2 weeks for 4 courses in the absence of disease progression or unacceptable toxicity. Celecoxib is stopped one week prior to surgery.

• Surgery: Patients undergo definitive surgery (either modified radical mastectomy or lumpectomy combined with axillary node dissection). Patients may also undergo adjuvant radiotherapy and hormonal therapy at the discretion of multidisciplinary breast team.

Blood is collected at baseline and examined for genetic polymorphisms associated with functional changes in proteins. Tumor tissue is obtained by needle biopsy at baseline, before the second course of docetaxel/capecitabine/celecoxib, and at surgical resection. Molecular markers and protein expression are assessed by immunohistochemistry using fluorescence-image analysis and real-time reverse-transcriptase PCR.

Patients undergo imaging comprising dynamic MRI, ultrasound, and mammogram at baseline and after the first and second 4 courses of chemotherapy.
