Purpose:

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving the drugs in different ways may kill more tumor cells. PURPOSE: Randomized phase II trial to compare the effectiveness of doxorubicin with paclitaxel in treating women who have locally advanced breast cancer.


Study summary:

OBJECTIVES: I. Assess the feasibility of obtaining serial biopsies in patients receiving neoadjuvant chemotherapy for locally advanced breast cancer. II. Assess the feasibility of performing assays of apoptosis and of markers that predict response on specimens obtained in these patients. III. Correlate the results of the assays with clinical and pathologic response rates. IV. Establish a baseline of change in apoptosis rates for future studies. V. Obtain serial blood samples and tumor tissue for future biological studies. OUTLINE: This is a randomized study. Patients are stratified by pre or postmenopausal state and T3 or T4 lesions. Arm I: Patients receive single agent doxorubicin by bolus infusion on day 1. Dose repeats every 14 days for a total of four courses, provided absolute neutrophil count (ANC) and platelet count remain in the appropriate range. Patients then receive paclitaxel IV administered over 3 hours once every 14 days for a total of four courses, provided ANC and platelet count remain in the appropriate range. Filgrastim (G-CSF) subcutaneous treatment is started on day 3 of each course, and continued for 7 days, or until ANC is greater than 10,000/mm3. Patients undergo serial core-needle breast biopsies or fine needle aspirations prior to starting therapy and on day one of each course. Arm II: Patients receive four courses of paclitaxel given once every 14 days. Patients then receive four courses of doxorubicin given on day 1 every 14 days, provided ANC and platelet count are in the appropriate range. G-CSF subcutaneous treatment is started on day 3 of each course, as in Arm I. Patients undergo serial core-needle breast biopsies or fine needle aspirations prior to starting and on day one of each course. Arm I and II: Upon completion of eight courses of chemotherapy, patients undergo a surgical procedure to evaluate the extent of residual disease and number of lymph nodes involved, and to achieve local control. Following surgery, patients receive additional treatment at the discretion of the treating oncologist. Eligible patients undergo further high dose chemotherapy with peripheral blood stem cell rescue; other patients receive cyclophosphamide therapy. Patients receiving lumpectomies receive breast irradiation. Patients receiving mastectomies might receive chest wall irradiation. Following radiotherapy, hormone receptor positive patients may start tamoxifen therapy for 5 years. PROJECTED ACCRUAL: An estimated 40 patients (20 per treatment arm) will be accrued for this study.
