Abstract

Microsatellite instability (MSI), which is caused by a deficient mismatch repair system, is seen in most of the hereditary non-polyposis colon cancers (HNPCC) and a portion of sporadic colorectal cancers. Forty unselected colorectal cancer patients were analyzed for MSI using silver stain plus kit. The overall incidence of MSI in studied cases was 17% (7/40). The incidence is similar result with previous study. MSI in colorectal carcers was more prevalent in moderative differentiated adenocarcinoma than well differentiated adenocarcinoma
