Department of Clinical Oncology, St Marianna University School of Medicine, Kawasaki, Japan.

mutations constitute an important poor prognostic factor in metastatic colorectal cancer (mCRC) and the development of treatments in this context is of great necessity to prolong patient survival. Although the association between mutations and microsatellite instability (MSI) has been known for several years, previous clinical trials have revealed that the former has a limited prognostic impact and that immune checkpoint inhibitors offer a significant survival benefit to mCRC patients with both characteristics. Furthermore, the genomic classification of mutations according to their molecular functions enables greater understanding of the characteristics of mCRC patients with mutations, with therapeutic strategies based on this classification made more ideal to improve poor prognosis through the delivery of targeted therapies.
