[Dysplasia and colorectal neoplasms in a group of patients with ulcerative rectocolitis (URC)]

In our Medical Department we examined 74 patients with ulcerative colitis between January 1987 and December 1992. All the patients have been controlled by colonoscopy and multiple rectal byopsies. As started by different studies, the ulcerative colitis is predictive of mucosal dysplasia alterations and colo-rectal carcinoma. Our experience confirms that the occurrence is not so high as reported by some preliminary studies. These results could probably attributed to better diagnostic and therapeutic strategies now available.
