Dysplasia and cancer in inflammatory bowel disease

Expert Rev Gastroenterol Hepatol. 2011 Feb;5(1):59-66. doi: 10.1586/egh.10.77.

Abstract

Inflammatory bowel disease (IBD) is a chronic gastrointestinal disease associated with an increased risk of colorectal cancer (CRC). Although CRC occurs in a minority of IBD patients (1%), it carries a high mortality and accounts for 20% of IBD-related mortality. Established risk factors for the development of CRC in IBD include disease duration of 8 years or more, family history of CRC, extensive colitis and primary sclerosing cholangitis. Meticulous colonoscopy and anti-inflammatory medications can reduce the risk of developing CRC. The future of IBD surveillance involves the use of novel endoscopic techniques (chromoendoscopy, narrow-band imaging, confocal laser endomicroscopy and autofluorescence) to enhance colonoscopic accuracy, in concert with chemopreventative medications to help reduce the risk of CRC in IBD.
