Clinicopathologic Features and Outcomes of Metaplastic Breast Carcinoma: Comparison with Invasive Ductal Carcinoma of the Breast

Abstract

MBC was characterized by a higher incidence of TNBC, larger tumor size, and lower tendency of axillary metastasis, and was difficult to diagnose with CNB. Although the incidence of stage IV disease at diagnosis was higher in MBC, the survival rates of stage I-III were comparable to those of IDC.
