Adjuvant Cyclophosphamide, Methotrexate, and Fluorouracil in Node-Positive Breast Cancer — The Results of 20 Years of Follow-up

Abstract
Adjuvant combination chemotherapy with cyclophosphamide, methotrexate, and fluorouracil was administered after radical mastectomy for primary breast cancer with histologically positive axillary lymph nodes to assess whether it would improve treatment outcome as compared with surgery alone. Here we report a 20-year follow-up of this investigation.
