Intestinal and diffuse types of gastric cancer: secular trends in Sweden since 1951.

Author information

Department of Surgery, University Hospital, Uppsala, Sweden.


In order to test the hypothesis that the general decline in gastric cancer observed in many countries is due to a selective decline in Laurén's intestinal type, we re-examined all 427 histologic sections obtained from gastric carcinomas diagnosed at the Department of Pathology, University Hospital, Uppsala, Sweden, in 1951, 1961, 1971-72 and 1981. The relative proportions of intestinal and diffuse type cancers were compared. The intestinal type was significantly (P less than 0.001) more common among elderly people than in the younger age groups. The relative proportions of intestinal type carcinoma in the four periods under study were 65%, 55%, 42% and 60%, respectively. The absence of any clearly discernible trend over time contradicts the hypothesis of diverse secular trends for intestinal and diffuse types of gastric carcinoma.
