 AIG(autoimmune gastritis)is a recognized cause of gastric cancer. Owing to the decline in Helicobacter pylori infection rates, its significance as a background disease for gastric cancer has relatively increased. In a retrospective study, in our department, comprising 194 patients with AIG, gastric cancer complications were documented in 36(18.6%)patients with 47 lesions. Patients with complicated gastric cancer were older, had a lower rate of positive endoscopic findings for adherent mucus, and higher intestinal metaplasia scores on biopsy specimen assessment as per the Updated Sydney system compared with those having uncomplicated gastric cancer. Gastric adenomas were also found in 26(13.4%)patients with AIG ; 4 lesions in four of the gastric cancers were malignant transformations of cases that had been followed up as gastric adenomas, indicating that adenomas also warranted attention.
