Epirubicin Plus Tamoxifen Versus Tamoxifen Alone in Node-Positive Postmenopausal Patients With Breast Cancer: A Randomized Trial of the International Collaborative Cancer Group

Abstract

The data show that combined chemohormonal treatment reduces the risk of relapse in postmenopausal patients with node-positive breast cancer. No evidence was found, however, for an improvement in overall survival. The size of benefit observed for both outcomes was consistent with that reported in the Early Breast Cancer Trialists' Collaborative Group overview. The trial presented here, however, provides the first report of an improvement in RFS associated with the provision of a single cytotoxic drug in addition to prolonged TAM.
