A Randomized Controlled Study of Postoperative Adjuvant Therapy of Uracil-tegafur (UFT) Compared With Cyclophosphamide/Methotrexate/5-fluorouracil (CMF) in Breast Cancer (NSAS-BC)

A Randomized Controlled Study of Postoperative Adjuvant Therapy of UFT Compared With CMF in High-risk Women With Axillary Node-negative Breast Cancer (NSAS-BC)

This is a randomized controlled study designed to evaluate the relapse-free survival of the UFT group compared with the CMF group. Patients will be randomly assigned to receive either CMF or UFT within 12 weeks after curative resection. To evaluate treatment efficacy, data on recurrence, and survival will be collected for up to 10 years after enrollment of the final patient. To assess safety, data on adverse events will be collected for 2 years after the start of treatment. Patients'quality of life will be assessed by means of a questionnaire.
