Abstract
Aliment Pharmacol Ther 31, 1104–1111 Summary Background Intestinal‐type gastric cancer (GC) still ranks among the high‐incidence, highly lethal malignancies. Atrophic gastritis is the cancerization field in which GC develops. The current histological reporting formats for gastritis do not include any (atrophy‐based) ranking of GC risk. Aim To test the gastritis OLGA‐staging (Operative Link for Gastritis Assessment) in prognosticating neoplastic progression. Methods Ninety‐three Italian patients were followed up for more than 12 years (range: 144–204 months). Clinical examinations, pepsinogen serology, endoscopy and histology (also assessing Helicobacter pylori status) were performed both at enrolment (T1) and at the end of the follow‐up (T2). Results All invasive or intra‐epithelial gastric neoplasia were consistently associated with high‐risk (III/IV) OLGA stages. There was a significant inverse correlation between the mean pepsinogen ratio and the OLGA stage (test for trend; P < 0.001). OLGA‐staging at T1 predicted both the OLGA stage (Kaplan–Maier log‐rank test, P = 0.001) and the neoplasia at T2 (Kaplan–Maier log‐rank test, P = 0.001). Conclusions This long‐term follow‐up study provides the first evidence that gastritis OLGA‐staging conveys relevant information on the clinico‐pathological outcome of gastritis and therefore for patient management. According to OLGA‐staging and H. pylori‐status, gastritis patients could be confidently stratified and managed according to their different cancer risks.Keywords
