During the period from January 1973 through December 1988, we have experineced 39 cases of double cancer of the large intestine and other organs. The incidence of double cancer among cancers of the large intestine was 39/525, or 7.4 %. Double cancer was synchronous in 10 (1.9 %) and metachronous in 29 (5.5 %). The first cancer of these double cancers developed in the large intestine in 11, and in other organs in 18 cases. <BR>Clinicopathological features of these double cancers of the large intestine and other organs were compared with those in 455 cases of solitary cancer of the the large intestine. There was no significant diffecence in the clincopathological feature between cases with double cancer and those with solitary cancer, but that the age of patients with secondary cancer of the large intestine was significantly higher than that of patients with solitary cancer of the large intestine. Operative results were satisfactory, if both of the double cancers were resected curatively.
