ABSTRACT
It is clear that colorectal cancer [CRC] develops through multiple genetic and epigenetic pathways. These pathways may be determined on the basis of three molecular features [i] mutations in DNA mismatch repair genes, leading to a DNA microsatellite instability [MSI] phenotype, [ii] mutations in APC and other genes that activate Wnt pathway, characterized by chromosomal instability [CIN] phenotype, and [iii] global genome hypermethylation, resulting in switch off of tumor suppressor genes, indicated as CpG island methylator phenotype [CIMP]. Each of these pathways is characterized by specific pathological features, mechanisms of carcinogenesis and process of tumor development. The molecular aspects of these pathways have been used clinically in the diagnosis, screening and management of patients with colorectal cancer. In this review we especially describe various aspects of CIMP, one of the important and rather recently discovered pathways that lead to colorectal cancer
