Summary
This study aimed to analyze the distribution characteristics of Helicobacter pylori（H. pylori） in varying stages of atrophic gastritis and early gastric cancer using immunohistochemical staining, with the goal of providing guidance for the early screening of gastric cancer. A retrospective analysis was conducted on gastric biopsy cases that underwent H. pylori immunohistochemical staining at our center from March 1, 2023, to August 15, 2025. Cases were classified into non-atrophic and atrophic groups based on the presence or absence of gastric atrophy. All cases were further divided into non-open and open atrophy groups and additionally into early gastric cancer and non-cancer groups. The distribution of H. pylori across subgroups was compared, and multivariate analyses were performed to identify risk factors associated with the development of early gastric cancer.
