Adjuvant Combination Chemotherapy in Node-Positive Breast Cancer
I. Determine whether higher doses of doxorubicin (DOX) used in an adjuvant regimen with cyclophosphamide (CTX) increase disease-free and overall survival in patients with early stage breast cancer. II. Determine whether paclitaxel (TAX) following 4 courses of CTX/DOX (CA) further improves disease-free and overall survival compared to CA alone. III. Determine whether TAX improves disease-free and overall survival at 3 different doses of DOX in the CA regimen, especially whether TAX following standard-dose DOX/CTX is more effective than high-dose DOX/CTX without TAX. IV. Assess the incidence of life-threatening and lethal toxicity with different doses of DOX in the CA regimen, with and without subsequent TAX. V. Determine whether the longer duration of chemotherapy for patients receiving TAX is associated with a reduction in local recurrence in patients whose definitive treatment was lumpectomy plus radiotherapy. VI. Assess the differences among the treatments in actual chemotherapy delivered, percentage of patients who experience delays in treatment delivery because of neutropenia and other treatment-related toxicity, number of hospital days required for recovery from febrile neutropenia on each course, and the incidence of platelet and erythrocyte transfusions on each course.

About 3,000 patients will be entered over 3 years. If accrual is insufficient after either 1 or 2 years, Arm II will be closed.
This is a randomized study. Patients are stratified by participating institution. Patients are randomized to one of three doses of doxorubicin and then randomized within each group to receive paclitaxel or not. The first group receives cyclophosphamide and standard-dose doxorubicin. The second group receives cyclophosphamide and medium-dose doxorubicin. The third group receives cyclophosphamide and high-dose doxorubicin. All groups receive 4 courses of therapy at 3-week intervals. Within each group, one half of the patients receive paclitaxel every 3 weeks for 4 weeks. All receptor-positive patients receive oral tamoxifen daily for 5 years. No other chemotherapy or hormonal therapy is permitted except steroids as antiemetics or for adrenal failure. Patients are followed every 3 months for 1 year, every 6 months for 2 years, and yearly thereafter.Published Results

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
