PD-L1 Protein Expression on Both Tumor Cells and Macrophages are Associated with Response to Neoadjuvant Durvalumab with Chemotherapy in Triple-negative Breast Cancer

Abstract

Expression of PD-L1 in tumor cells, immune cells in stroma, and colocalized with CD68⁺ cells is associated with higher rates of pCR to durvalumab and chemotherapy in TNBC.
