Abstract

The role of Helicobacter pylori in gastric carcinogenesis is a subject of an increasing interest. In this report we describe a prospective study on the resected stomachs to establish the prevalence of H. pylori in different types of gastric carcinoma. The material consisted of 62 consecutive patients operated on stomach adenocarcinomas Fifty six percent of the patients were intestinal type, 34%--diffuse type and 10%--mixed type. The presence of H. pylori was studied in specimens from surgically removed stomachs. The conformation of the bacterial infection was done by means of rapid urease test, microbiological culture, Warthin-Starry and immunohistochemical staining. The overall prevalence of H. pylori infection was 69% (43/62). There was a statistically significant difference in the infection rates between the types of carcinoma--75% in the intestinal type and 62% in the diffuse type. The most sensitive was immunohistochemical staining. The bacterial colonies were cumulated far from the tumor tissue. In cardiac cancer the most intense of infection was an antrum and lower part of gastric body. In opposite; in antrum and pylorus cancer the scope of colonisation increased in fundus and subcardiac region with statistical significa...Continue Reading

Atrophic Gastritis

Atrophic Gastritis is a process where gastric glandular cells are lost and replaced with firbous tissues, as a result of chronic inflammation. Learn more about Atrophic Gastritis here.
