Abstract

Microsatellite instability occurs in the colonic mucosa of patients with inflammatory bowel disease and may predispose the mucosa to neoplastic transformation. It is unknown whether microsatellite instability also plays a role in the neoplastic risk associated with primary sclerosing cholangitis. We examined 134 tissue samples from 21 patients with sclerosing cholangitis for microsatellite instability at eight loci. All tissues were also stained immunohistochemically using an antibody to the proliferation marker Ki-67. Microsatellite instability did not occur in any samples from the intrahepatic or extrahepatic biliary system, although one patient demonstrated instability in the colon. Ki-67 indices ranged from 0 to 2.5 in nondysplastic biliary epithelium and from 1.5 to 29.4 in areas of dysplasia. The absence of microsatellite instability in sclerosing cholangitis suggests that the genetic basis of neoplastic progression in chronic inflammatory disease of the bile ducts differs from that of intestinal cancers arising in the setting of chronic inflammatory bowel disease and may relate to differences in the microenvironment in these two sites.
