Microsatellite Instability in Colorectal Cancer: Time to Stop Hiding!

Microsatellite Instability in Colorectal Cancer: Time to Stop Hiding!

Colorectal cancer (CRC) is the second cause of cancer-related death worldwide. Surgery constitutes the primary therapy for these tumors, together with chemotherapy that is usually recommended in patients with metastatic primary CRC. Although molecularly distinct entities arising from different physiopathogenic mechanisms-microsatellite (MSI) and chromosomal instability (also called microsatelli...

Microsatellite instability in colorectal cancer

BACKGROUND Colorectal cancer (CRC) is the third most common cancer in the world. In 75% CRC develops sporadically, in 25% hereditary or as a consequence of inflammatory bowel disease. CRC carcinogenesis develops over many years. The cause of CRC in 85% is chromosomal instability (CIN) and in 15% microsatellite instability (MSI-H), where hereditary nonpolyposis colorectal cancer (HNPCC) represen...

Microsatellite instability in colitis associated colorectal cancer

Microsatellite instability in colitis associated colorectal cancer As molecular pathways of colon carcinogenesis continue to be defined for high risk hereditary colon cancer syndromes and for average risk sporadic colon cancers, it seems that colon carcinogenesis in the setting of chronic idiopathic inflammatory bowel disease (IBD) may be unique. 1 Although to some extent this notion seems intu...

Microsatellite instability in colorectal cancer: clinicopathological significance.

Although often viewed as a single disease, colorectal cancer more accurately represents a constellation of heterogeneous subtypes that result from different combinations of genetic events and epigenetic alterations. Chromosomal instability (CIN), microsatellite instability (MSI) and CpG island methylator phenotype (CIMP) have been identified as the three major molecular characteristics, which i...
