PD-L1 expression in urothelial carcinomas. The panels show pT2–4 urothelial carcinomas with strong PD-L1 staining in tumor cells only (A), weak PD-L1 staining in tumor cells and prominent positivity in immune cells (B), strong PD-L1 staining in immune cells only (C), and complete absence of PD-L1 staining (D). Examples of pTa tumors show a prominent PD-L1 positivity of peritumoral macrophages (E) and absence of PD-L1 staining (F)
