Fig. 5From: Infiltrating stromal immune cells in inflammatory breast cancer are associated with an improved outcome and increased PD-L1 expressionPD-L1+ immune cells (AB: SP142, Brown DAB staining) in IBC (× 250). There is a strong association between PD-L1 and sTIL, without PD-L1 expression on the tumour cells. This suggests an adaptive expression pattern. a High PD-L1 expression (> 10%, category 3). b Low PD-L1 expression (> 1% and < 5%, category 1)Back to article page
