Abstract

Colorectal cancers treated with targeted therapies frequently acquire numerous subclonal genomic alterations. Tumor mutational burden (TMB) is under investigation as a biomarker for predicting response to immunotherapy in microsatellite-stable metastatic colorectal cancer. In this study, we contextualize a recent study evaluating high plasma TMB after targeted therapy and its implications for immunotherapy. See related article by Yeh et al., p. 1100.
