Prognoses were analyzed for cases of ulcerative colitis (UC)associated and sporadic colon carcinomas of stages 2 and 3. For all cases, UC-associated carcinoma showed worse overall survival than sporadic carcinoma (P = 0.010). When cases were limited to well differentiated carcinomas, no significant difference was shown (P = 0.136). Similarly, the cases limited to moderately to poorly differentiated ones, no significant difference was shown (P = 0.071).
