Comparison of CD163, CD8, and PD-L1 expressions between pCR group and non-pCR group. Higher PD-L1 expression, higher level of CD8-positive cytotoxic T cells, but lower infiltration of CD163-positive M2 macrophages were identified in the pCR group with respect to the non-pCR group in TNBC patients treated with neoadjuvant chemotherapy (x 200).
