Abstract excerpt
Pembrolizumab was recently approved for treatment of cancers with high tumor mutational burden (TMB). We conduct a focused literature review of TMB as a predictive biomarker. TMB quantifies the sum of nonsynonymous coding mutations (typically single nucleotide substitutions and short insertion-deletions) per megabase of sequenced DNA. As a proxy for expression of immunogenic neoantigens, TMB may be an effective...
