Recent advances in endoscopic technology allow detailed observation of the gastric mucosa.Today,endoscopy is used in the diagnosis of gastritis to determine the presence/absence of Helicobacter pylori(H.pylori)infection and evaluate gastric cancer risk.In 2013,the Japan Gastroenterological Endoscopy Society advocated the Kyoto classification,a new grading system for endoscopic gastritis.The Kyoto classification organized endoscopic findings related to H.pylori infection.The Kyoto classification score is the sum of scores for five endoscopic findings(atrophy,intestinal metaplasia,Enlarged folds,nodularity,and diffuse redness with or without regular arrangement of collecting venules)and ranges from 0 to 8.Atrophy,intestinal metaplasia,Enlarged folds,and nodularity contribute to gastric cancer risk.Diffuse redness and regular arrangement of collecting venules are related to H.pylori infection status.In subjects without a history of H.pylori eradication,the infection rates in those with Kyoto scores of 0,1,and≥2 were 1.5%,45%,and 82%,respectively.A Kyoto classification score of 0 indicates no H.pylori infection.A Kyoto classification score of 2 or more indicates H.pylori infection.Kyoto classification scores of patients with and without gastric cancer were 4.8 and 3.8,respectively.A Kyoto classification score of 4 or more might indicate gastric cancer risk.

BACKGROUND Accurate diagnosis of the depth of gastric cancer invasion is crucial in clinical practice.The diagnosis of gastric cancer depth is often made using endoscopic characteristics of the tumor and its margins;however,evaluating invasion depth based on endoscopic background gastritis remains unclear.AIM To investigate predicting submucosal invasion using the endoscopy-based Kyoto classification of gastritis.METHODS Patients with gastric cancer detected on esophagogastroduodenoscopy at Toyoshima Endoscopy Clinic were enrolled.We analyzed the effects of patient and tumor characteristics,including age,sex,body mass index,surveillance endoscopy within 2 years,current Helicobacter pylori infection,the Kyoto classification,and Lauren’s tumor type,on submucosal tumor invasion and curative endoscopic resection.The Kyoto classification included atrophy,intestinal metaplasia,Enlarged folds,nodularity,and diffuse redness.Atrophy was characterized by non-reddish and low mucosa.Intestinal metaplasia was detected as patchy whitish or grayish-white flat elevations,forming an irregular uneven surface.An Enlarged fold referred to a fold width≥5 mm in the greater curvature of the corpus.Nodularity was characterized by goosebump-like multiple nodules in the antrum.Diffuse redness was characterized by uniform reddish nonatrophic mucosa in the greater curvature of the corpus.RESULTS A total of 266 gastric cancer patients(mean age,66.7 years;male sex,58.6%;mean body mass index,22.8 kg/m2)were enrolled.Ninety-three patients underwent esophagogastroduodenoscopy for surveillance within 2 years,and 140 had current Helicobacter pylori infection.The mean Kyoto score was 4.54.Fifty-eight cancers were diffuse-type,and 87 cancers had invaded the submucosa.Multivariate analysis revealed that low body mass index(odds ratio 0.88,P=0.02),no surveillance esophagogastroduodenoscopy within 2 years(odds ratio 0.15,PEnlarged folds of gastritis(odds ratio 3.39,P=0.001),and Lauren’s diffuse-type(odds ratio 5.09,P<0.001)were indep
