IHC staining of PD-L1 and PD-1 expressions in TMA samples. PD-1 displayed a membrane-accentuated expression, which was often accompanied by a cytoplasmic expression (b), while PD-L1showed a membrane-accentuated expression (d). Tumor infiltrating lymphocytes were indicated by red arrows. The representative pictures of negative expression of PD-1/PD-L1 were also shown (a, c)
