Critical checkpoints for host and tumor profiling. A multiplexed biomarker approach is highly integrative and includes both tumor- and immune-related parameters assessed with both molecular and image-based methods for individualized prediction of immunotherapy response. By assessing patient samples continuously one can collect a dynamic data on tissue-based parameters, such as immune cell infiltration and expression of immune checkpoints, and pathology methods. These parameters are equally suited for data integration with molecular parameters. TILs: tumor-infiltrating lymphocytes. PD-L1: programmed cell death-ligand 1. Immunoscore: a prognostic tool for quantification of in situ immune cell infiltrates. Immunocompetence: body’s ability to produce a normal immune response following exposure to an antigen
