Nineteen patients with cancer of colon or of rectum treated in our department in the past 16years (1965-1980) were studied on the factors possibly related to the occurrence of these cancers directly or indirectly. In one case, derm atomyositis was seen concomitantly with the rectal cancer.
In other two cases, uterine or gastric cancer were recognized antecedently or subsequently to the colon cancer respectively. And also, carcinomatous diathesis was found in the family history of 2 cases; in one of which, his father had similarly suffered from colon cancer.
Moreover, antecedent diabetes mellitus were complicated in 3 (15.8%) among the 19 colon cancer cases, the frequency being higher than that in the population of the country: the relationship between the diabetes mellitus and the occurrence of colon cancer should be further investigated.
Although the number of the cases examined was limited, these findings seem to suggest that autoimtnune diseases such as dermatomyositis, antecedent cancers, hereditary loading of carci nomatous diathesis, and also diabetes mellitus may affect the incidence of colon or rectal cancer.
