This explains the importance of personification of immunotherapy and the search for predictive markers. The article is devoted to the review of clinically significant biomarkers of the effectiveness of immunotherapy, such as PD-L1 expression in tumor tissue, microsatellite instability, tumor mutation burden and tumor infiltrating lymphocytes.
