Colorectal cancer (CRC) was one of the first cancers to be characterized from a molecular point of view. Initially divided into three molecular groups (chromosomal instability, microsatellite instability and methylator phenotype), CRC are now classified under four robust subtypes according to a consensual transcription-based molecular classification (“Consensus Molecular Subtypes”, CMS). These groups are firmly linked to biological, genomic and epigenetic characteristics, as well as survival rates. The CMS classification of CRC represents a major advance in our understanding of the molecular mechanisms behind the malignant transformation of colonic epithelial cells, and opens the way for development of a precision-based approach for this cancer.
