Abstract
Twenty patients with carcinoma of the gastric remnant after surgery for benign disease have been studied. The histologic and histochemical data on gastric mucosa surrounding the carcinoma have been compared with data from 60 biopsy samples taken from gastric stumps without carcinoma in an age- and sex-matched group. There was a high incidence of intestinal metaplasia in the gastric stumps (24 of 60); it was even higher in the cases with a carcinoma (17 of 18). Intestinal metaplasia Type III, which is closely related to the carcinoma in a stomach not surgically treated, was rare in cases of cancer in the gastric stump (1 in 18). This finding is correlated to the high frequency of the diffuse type of carcinomas that occur in the gastric stump (15 of 20), which are rarely associated with intestinal metaplasia. Therefore, identifying intestinal metaplasia types does not always point to the fact that affected patients will also be at high risk for cancer in their gastric remnant.
