Cyclophosphamide, Methotrexate, and Fluorouracil, With or Without Epirubicin Hydrochloride, in Treating Women Who Have Undergone Surgery for Breast Cancer (Group III Closed to New Patients as of 12/7/2009)

- Brief Summary
RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, methotrexate, fluorouracil, and epirubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving cyclophosphamide together with methotrexate and fluorouracil before, after, or without epirubicin hydrochloride is more effective in treating patients with breast cancer that can be removed by surgery.
PURPOSE: This randomized phase III trial is comparing three regimens of cyclophosphamide given together with methotrexate and fluorouracil, with or without epirubicin hydrochloride, to see how well it works in treating women who have undergone surgery for breast cancer. (Group III was closed to new patients as of 12/7/2009.)
- Detailed Description
OBJECTIVES:
Primary
* To determine the impact of adjuvant chemotherapy comprising epirubicin hydrochloride followed by cyclophosphamide, methotrexate, and fluorouracil versus cyclophosphamide, methotrexate, and fluorouracil followed by epirubicin hydrochloride versus cyclophosphamide, methotrexate, and fluorouracil on overall survival of patients with biologically aggressive, resectable, node-negative or node-positive breast cancer.
Secondary
* To assess the disease-free survival and patterns of relapse in these patients.
* To assess the tolerance to and toxicity of treatment in these patients.
* To determine the quality of life of these patients.
* To verify the effectiveness of these treatments in different subgroups of patients.
* To collect, retrospectively, information on the expression of tumor suppressor gene p53, oncogene c-erbB-2, and bcl-2 protein involved in apoptosis. (exploratory)
OUTLINE: This is a multicenter study. Patients are stratified according to center, lymph node status (N0 vs N1-3), and estrogen receptor status (negative vs positive). Patients are randomized to 1 of 3 treatment arms.
* Arm I: Beginning 4-6 weeks following surgery, patients receive epirubicin hydrochloride IV on day 1. Treatment repeats every 3 weeks for 4 courses. Patients then receive cyclophosphamide IV, methotrexate IV, and fluorouracil IV on days 1-8. Treatment repeats every 4 weeks for 4 courses.
* Arm II: Beginning 4-6 weeks following surgery, patients receive cyclophosphamide IV, methotrexate IV, and fluorouracil IV on days 1-8. Treatment repeats every 4 weeks for 4 courses. Patients then receive epirubicin hydrochloride IV on day 1. Treatment repeats every 3 weeks for 4 courses.
* Arm III (closed to accrual as of 12/7/2009): Beginning 4-6 weeks following surgery, patients receive cyclophosphamide IV, methotrexate IV, and fluorouracil IV on days 1-8. Treatment repeats every 4 weeks for 6 courses.
Patients with estrogen receptor-positive disease receive tamoxifen daily for 5 years after completing chemotherapy.
After completion of study therapy, patients are followed every 3 months for 1 year, every 6 months for 4 years, and then annually for 5 years.
