Mammostrat As an Immunohistochemical Multigene Assay for Prediction of Early Relapse Risk in the Tamoxifen Versus Exemestane Adjuvant Multicenter Trial Pathology Study

Abstract

The Mammostrat score predicts DRFS for patients treated with exemestane and patients treated with tamoxifen followed by exemestane irrespective of nodal status and chemotherapy. The ability of this test to provide additional outcome data after treatment provides additional evidence of its use in risk stratification of ER-positive postmenopausal patients with breast cancer.
