PD-L1 immunohistochemical staining. (a) Area of a LUAC of solid predominant histological pattern showing strong membranous PD-L1 staining in 100% of the tumor cells, therefore scored as “high positive”; (b) Area from a LUAC showing focally moderate-weak membrane staining in 15% of the tumor cells, scored as “low positive”; (c) Area from a LUAC with complete absence of PD-L1 staining 0%, in the presence of internal positive control (immune cells), scored as “negative”.
