abstract = "OBJECTIVE: Intercellular adhesion molecule-1 (ICAM-1) is important in ulcerative colitis (UC) by mediating the arrest and further migration of neutrophils. In vitro studies have shown that colonocytes from chronically inflamed colon and cultured colon cancer cells are capable of expressing ICAM-1. The aim of this study was to assess the ICAM-1 expression in human colonic tissue representing UC, Crohn's disease (CD), adenomas, and adenocarcinomas, with special attention to the epithelium.MATERIAL AND METHODS: Formalin-fixed and paraffin-embedded tissue from the archives of the Department of Pathology of Rigshospitalet University of Copenhagen was examined. Colonic tissue from 10 patients with UC, 10 with CD, 32 adenomas, 27 adenocarcinomas, and 10 lymph node metastases were included. The expression of ICAM-1 was assessed by using the EnVision(+)technique (DakoCytomation).RESULTS: Endothelial ICAM-1 was up-regulated in areas with dense lymphocyte infiltration and near crypt abscesses and ulcerations. Ulcerations were covered by a continuous layer of macrophages and epithelial cells expressing ICAM-1. Similar observations were made in the case of adenomas and adenocarcinomas, but in adenocarcinomas the epithelial ICAM-1 was more diffuse and not related solely to sites of surface destruction.CONCLUSIONS: In the colon, endothelial cells, macrophages, and epithelial cells are in certain conditions capable of expressing ICAM-1. Although the ICAM-1 expression was related to both the degree and the nature of inflammation, the data indicate increased susceptibility of cancer cells to express ICAM-1. Epithelial and macrophage ICAM-1 might be involved in the immune surveillance and the first-line defense of the diseased colon.",
