Ulcerative colitis and Crohn's disease have an approximately 2-3-fold increased risk of colorectal cancers. The risk factors most frequently associated with the risk of these cancers in inflammatory bowel disease are those indicative of chronic inflammation, primary sclerosing cholangitis, previous dysplasia, and a family history of colorectal cancers. The pace of CRC surveillance in this population will be determined by the presence of these risk factors, and the surveillance modality is based on colonoscopy with chromoendoscopy and targeted biopsies. In the absence of staining, systematic biopsies can be performed.
