The Correlation of PD-L1 Expression in Metaplastic BreastCancers with Clinical-Pathological Features and Prognosis

2026-03-09

Abstract excerpt

<h4>Background: </h4> and Objectives: Metaplastic breast carcinoma (MBC) is a rare, aggressive malignancy often resistant to conventional chemotherapy and characterized by a triple-negative phenotype. While immune checkpoint inhibition shows promise, the prognostic significance and distribution of programmed death-ligand 1 (PD-L1) expression within the heterogeneous architecture of MBC remain poorly understood. Th...
