Neoplastic precursor lesions related to the development of cancer in inflammatory bowel disease.
Dysplasia is an intermediate stage in the progression from inflammation to cancer in patients with inflammatory bowel disease. Clinically, dysplasia is used to define appropriate endpoints for colectomy in high-risk patients undergoing endoscopic surveillance. Surveillance is currently the only credible alternative to prophylactic colectomy for high-risk patients. The success of surveillance can be maximized by adherence of gastroenterologists to recommended procedural guidelines, adherence of pathologists to standardized histological criteria and nomenclature, and a joint commitment to close clinical-pathological communication. Technical enhancements to conventional endoscopy hold promise of improved efficiency and accuracy. Molecular-based testing may have a future role for risk stratification and early detection of neoplasia in inflammatory bowel disease.
