Abstract excerpt
PURPOSE: Microsatellite stable (MSS) colorectal cancers, in contrast to microsatellite instability-high colorectal cancers, have few mutations and are insensitive to immune checkpoint blockade (ICB). Colorectal cancers treated with targeted agents often acquire a high number of genomic alterations at progression. We asked whether targeted therapy could be used to generate a high tumor mutational burden (TMB) in...
