Microsatellite Instability, Prognosis and Drug Sensitivity of Stage II and III Colorectal Cancer: More Complexity to the Puzzle
19 May 2011
Abstract excerpt
Microsatellite instability (MSI), the abnormal shortening or lengthening of DNA by 1–6 repeating base pair units, is the result of inactivation of the DNA mismatch repair (MMR) system and characterizes approximately 15% of colorectal cancers (CRCs) ( 1 ). Two distinct mechanisms can cause MMR deficiency (dMMR): 1) germline mutational inactivation of the MMR genes, present in CRC patients with Lynch Syndrome and...
