Combination Chemotherapy With or Without Epirubicin in Treating Women With Stage I or Stage II Breast Cancer

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 may kill more tumor cells. It is not yet known whether combination chemotherapy plus epirubicin is more effective than combination chemotherapy alone for stage I or stage II breast cancer. PURPOSE: This randomized phase III trial is studying combination chemotherapy alone to see how well it works compared to combination chemotherapy and epirubicin in treating women with stage I or stage II breast cancer who have undergone surgery to remove the tumor.
