Effective
immunotherapies require the use of biomarkers for diagnostic screening. This includes neoantigen expression, gene signatures and expression profiles, chemokine ratios, cell counts, and immune scores. There are several immune-related biomarkers which can be used to predict clinical outcomes and include the mutational load for CTLA-4 and PD-1 blockage therapy, CD3 T-cell counts, CD8/FOXP3 ratio for tumor necrosis, CD4+ICOS+ T cells, and broad antibody signature in protein microarray-based seromics.
