Details and patient eligibility

About

Three clinical research coordinators recruited patients aged 40-75 who underwent screening endoscopy at the Digestive Endoscopy Center of Qilu Hospital from July 1, 2022, to July 30, 2024. All participating patients provided written informed consent. Baseline information such as height, weight, age, sex, smoking and alcohol consumption status, HP status, and family history of gastrointestinal tumors were recorded before endoscopy. During endoscopy, the endoscopist observed and photographed the lesser and greater curvature of the antrum, corpus, and incisura, performed the Kimura-Takemoto classification, and classified those with a Kimura-Takemoto score of C0 as non-atrophic gastritis and those with C1-O3 as atrophic gastritis. Patients with atrophic gastritis received free multiple-site biopsies for pathological assessment, including targeted biopsies of suspected IM areas and random biopsies from Sydney classification sites. At least four biopsies were taken from the lesser and greater curvature of the antrum and corpus for pathological evaluation, and OLGIM staging was calculated based on the results.
