Abstract
Patients with longstanding ulcerative colitis and Crohn's colitis are at increased risk of colorectal neoplasia Chronic inflammation is considered to be the driving force that predisposes to developing colorectal neoplasia in IBD. The same molecular pathways that contribute to sporadic colon carcinogenesis also occur with colitis-associatedcolorectal cancer, albeit with different frequency and timing. Some molecular markers, such as aneuploidy, correlate with colon cancer risk, but so far no marker has beenintegrated into clinical practice for predicting cancer risk. Newer markers and approaches hold promise for helping to identify IBD patients at high risk of developing colorectalcancer.
