The clinical and pathological features of 29 mucinous carcinomas of the large intestine were compared with those of 314 well or moderately differentiated adenocarcinomas (non mucinous carcinomas).<BR>A higher proportion of mucinous carcinomas developed more proximal distribution to the splenic flexure than non mucinous carcinomas. Macroscopic type of mucinous carcinomas tended to be protruded, and the mean size of mucinous carcinomas was larger than that of non mucinous carcinomas. The incidence of the presence of invasion to adjacent orgargans, lymph node metastasis and peritoneal dissemination was higher in mucinous carcinomas than non mucinous carcinomas.<BR>The 5-year survival rate of mucinous carcinomas was significantly less than that of non mucinous carcinomas (p<0.05).<BR>Regarding the histologic stubtype of mucinous carcinomas, the incidence of the presence of peritoneal dissemination was higher in the poorly differentiated type than the well differentiated type, and the 5-year survival rate of poorly or moderately differentiated type was significantiy worse than that of well differentiated type (p<0.03).
