The Sydney System is the most widely used classification of this disease but it does not allow a ranking of patients according to the evolutionary potential of the disease, unlike the classifications: “Operative Link On Gastritis Assessment” (OLGA) and “Operative Link on Gastritis Intestinal Metaplasia Assessment” (OLGIM). Our goals are to apply and evaluate the three classifications: the Sydney System, OLGA and OLGIM and to draw possible correlations. This is a retrospective, descriptive, single-center study performed on all cases of chronic gastritis, diagnosed at the laboratory of Pathological Anatomy Unit of Joseph Ravoahangy Andrianavalona University Hospital from January 1, 2013 to December 31, 2017. A review and application of the three main classification systems was performed on each case. We included 298 cases. The mean age was 50.85 years. The sex ratio was 1.48. The high-risk stages according to the “Operative Link On Gastritis Assessment” (OLGA) system and the “Operative Link on Gastritis Intestinal Metaplasia Assessment” (OLGIM) system were 0.67% and 2.68%, respectively. We observed a correlation between the two systems with discordance of 5%. The use of the two new systems allows the assessment of the progressive potential of gastritis in patients at risk of developing gastric cancer. For optimal effectiveness of both classifications, biopsies should be performed according to the Sydney System recommendations.展开更多

The presence and stage of precancerous lesions as well as subtype of intestinal metaplasia at the baseline endoscopy got evaluated. Literature mini-review was performed.RESULTS Out of 1681 subjects in the Biobank, gastric adenocarcinoma was detected in five cases in whom previous endoscopy data with biopsies either from the corpus or antral part were available. All of the patients had incomplete intestinal metaplasia during the baseline endoscopy;all three subjects in whom intestinal metaplasia subtyping was performed according to Filipe et al, had Type Ⅲ intestinal metaplasia. Two of the five cases had low Operative Link on Gastritis Assessment(OLGA) and Operative Link on Gastritis Intestinal Metaplasia Assessment(OLGIM) stages(Ⅰ-Ⅱ) at the baseline.CONCLUSION The presence of incomplete intestinal metaplasia, in particular, that of Type Ⅲ is a better predictor for gastric adenocarcinoma development than OLGA/OLGIM staging system. Subtyping of intestinal metaplasia have an important role in the risk stratification for surveillance decisions.展开更多
