| Research Abstract |
In the surveillance of colitic cancer in patients with long-standing inflammatory bowel disease, majority of the lesions were detectable under chromo-endoscopy, however, a part of flat lesions were not detectable. Photo-dynamic diagnosis (PDD) was useful to detect such lesions. Furthermore dysfunction in regulatory T cells and auto-reactive T cells were found in such long-standing cases, suggesting immune-regulatory dysfunction may play significant roles in the development of colitic neoplasia.
