Conditions: Breast Cancer
Purpose: RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin, and paclitaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known whether giving cyclophosphamide together with doxorubicin is more effective than giving paclitaxel alone in treating breast cancer. PURPOSE: This randomized phase III trial is studying cyclophosphamide and doxorubicin to see how well they work compared to paclitaxel in treating women with invasive breast cancer.
Study summary: OBJECTIVES: Primary - Compare the disease-free survival of women with operable breast cancer and 0-3 positive axillary lymph nodes treated with two different schedules (4 vs 6 courses) of adjuvant cyclophosphamide and doxorubicin vs paclitaxel. (Arms II and IV closed to accrual as of 1/30/2008) - Compare the disease-free survival of patients treated with these regimens. Secondary - Compare overall survival, local control, and time to distant metastasis in patients treated with these regimens. - Compare the toxic effects of these regimens in these patients. - Compare the effect of these regimens on the induction of menopause in premenopausal patients. - Determine the discrepancy of myelosuppression in patients with MDR1 haplotypes on the CA treatment arm. - Compare the disease-free survival of patients with MDR1 haplotypes treated with these regimens. - Correlate CYP3A5, CYP2C8, and CYP2B6 polymorphisms with disease-free survival and toxicity in patients treated with these regimens. OUTLINE: This is a randomized study. Patients are stratified according to menopausal status (premenopausal vs postmenopausal), estrogen receptor (ER)/progesterone receptor (PR) status (ER and/or PR positive or unknown vs ER and PR negative), and HER2/neu status (negative vs unknown vs positive [by immunohistochemistry 3+ staining or gene amplification by fluorescence in situ hybridization]). Patients are randomized to 1 of 4 treatment arms (arms II and IV closed to accrual as of 1/30/2008). - Arm I: Patients receive doxorubicin IV and cyclophosphamide IV on day 1. Treatment repeats every 14 days for 4 courses. - Arm II (closed to accrual as of 1/30/2008): Patients receive doxorubicin and cyclophosphamide as in arm I. Treatment repeats every 14 days for 6 courses. - Arm III: Patients receive paclitaxel IV over 1 hour on day 1. Treatment repeats every 14 days for 4 courses. - Arm IV (closed to accrual as of 1/30/2008): Patients receive paclitaxel as in arm III. Treatment repeats every 14 days for 6 courses. Treatment in all arms continues in the absence of disease progression or unacceptable toxicity. Lumpectomy patients must then undergo radiotherapy. Mastectomy patients undergo radiotherapy at the discretion of the treating physician. Patients are followed every 6 months for 2 years and then annually for 15 years. PROJECTED ACCRUAL: A total of 4,646 patients will be accrued for this study within 29 months.
