Abstract
Recent clinical trials have demonstrated that it is possible to induce durable remission in several tumors (non-small cell lung cancer (NSCLC), melanoma, squamous cancer of head and neck, renal cell carcinoma, Hodgkin lymphoma, colorectal cancer) by blocking the PD-1/PD-L1 (programmed death-1/programmed death-ligand 1) axis with anti-PD-1 or anti-PD-L1 antibodies and that an objective clinical response was closely associated with immunohistochemical PD-L1expression in tumor cells. Because immunohistochemistry is widely accepted and used method for PD-L1 assessment it is important to defi ne criteria for selecting patients who are candidates for immunotherapy and can benefi t from it.
