[Modifications of gastric mucosa in diffuse and intestinal cancer].
The study was made of 29 intestinal type gastric carcinomas, 37 diffuse type gastric carcinomas and stomach mucosa (SM). Both carcinomas slightly differed by frequency of the fundal glands atrophy. Intestinal type was characterized by a higher frequency of antral glands atrophy, intestinal metaplasia, particularly of colon type. Intestinal cell differentiation was about the same in both types. Hyperplasia of lining and endocrine cells in the fundal part of the mucosa was more frequent and neuroendocrine differentiation was more pronounced in diffuse stomach carcinoma. It is suggested that environmental impacts including helicobacter pylori result in proliferation of the epithelium, intestinal metaplasia, dysplasia and carcinoma of the intestinal type. Diffuse carcinoma is associated with proliferation of glandular epithelium (parietal, endocrine, cervical) due to genetic factors, hypergastrinemia caused by fundal gland atrophy, alkalization of the mucosa due to Helicobacter pylori infection.
