Utility of exome sequencing in routine care for metastatic colorectal cancer.

ABSTRACT: Metastatic colorectal cancer (mCRC) is a heterogenous disease and its prognosis depends on clinical features, such as tumor sidedness, and whether it is metachronous or synchronous. However, little is known about the overall genomic characterization of mCRC in these clinical subtypes. This single-center observational study included 77 patients with mCRC who underwent somatic and germline exome analysis during the first or second line of therapy in 2018. Somatic and germline variants were determined in addition to tumor mutational burden, ploidy, clonality, human leucocyte antigen typing, neoantigens, and mutational and copy number signatures. Variables associated with sidedness, synchronous status and RAS status were determined using Fisher's test; and variables associated with overall sur
