Abstract

There is a strong association between chronic inflammation and cancer formation. This correlation has been well observed in patients with long standing inflammatory bowel disease (IBD) who are at high risk of colorectal cancer (CRC). At present, there is a lack of good markers for predicting the progression from normal to neoplastic mucosa in patients with IBD. IBD patients who are ‘at-risk’ of CRC should be identified, evaluated and should also be enrolled in surveillance program, regardless of their disease activity. Early identification of dysplasia and its appropriate management using endoscopic techniques or surgery are essential in patients with long-standing IBD, to minimize CRC morbidity and mortality. Gastroenterologists should work along with experienced, specialised gastrointestinal pathologists, surgeons and with fully informed and compliant IBD patients' to ensure the success of surveillance programme in early detection of CRC.
