Gastric cancer risk assessment of gastritis in clinical practice by using the histological information recommended by the updated Sydney system: The OLGIMA system

Aims The OLGA system assesses both gastric atrophy (GA) and intestinal metaplasia (IM) together as a severity overall which must be estimated by pathologists. The OLGIM system is based on the IM severity recommended by the updated Sydney system. Thus, the final OLGIM score can be estimated by any clinician. Currently, there is no system that addresses the severity of both the GA and IM as they are reported following the updated Sydney system recommendation. This study aimed to assess the utility of a new system, OLGIMA (Operative Link on Gastric IM and GA assessment), as a tool to identify patients at higher risk for GC in daily practice.
