RATIONALE: It is not yet known which combination of surgeries is more effective in reducing side effects and improving recovery in treating breast cancer. PURPOSE: This randomized phase III trial is comparing how well axillary lymph node dissection with either mastectomy or excisional biopsy plus radiation therapy works in treating women with stage I or stage II breast cancer.

Study summary:

OBJECTIVES: - Compare the overall and disease-free survival of women with stage I or II breast cancer treated with mastectomy and axillary dissection vs excisional biopsy, axillary dissection, and definitive radiotherapy. - Compare in-breast only failure in patients treated with these regimens. OUTLINE: This is a randomized study. Patients are randomized to 1 of 2 treatment arms. - Arm I: Patients undergo total mastectomy and axillary dissection. - Arm II: Patients undergo excisional biopsy and axillary dissection followed by whole breast radiotherapy and a boost to the tumor bed. Patients with positive axillary dissections undergo radiotherapy to the supraclavicular nodes. In both arms, patients with positive nodes receive cyclophosphamide and doxorubicin. Patients are followed for at least 20 years. PROJECTED ACCRUAL: A total of 237 patients (116 for arm I and 121 for arm II) were accrued for this study within 8 years.
