Description

Background and objective : Among private hospitals in Tokyo, there is currently little report about statistics of cancer which detected by diagnostic endoscopic procedures. We performed digestive endoscopy through 30 years. We focus on the character of early gastric cancer cases detected in this series of study including the endoscopic findings and pathological examinations.<br> Methods : From February 1982 to January 2012, 22821 cases of EGD (esophagogastroduodenoscopy) were performed for symptomatic patients. Among them, 186 cases of early gastric cancer in 175 patients were identified. They diagnosed cancer by pathological study followed by endoscopic biopsy, EMR, ESD and surgical operative procedures.<br> Results : The early gastric cancer group includes 175 (44.5%) patients of 393 total gastric cancer patients. In the early gastric cancer group, Male, Aged 65-74 years group were mostly detected. Focus on the cancer locations, M (middle body of stomach) lesion 101 cases (54.3%) , L (lower body) lesion 67 cases (36.0%) , and U (upper body) lesion 15 cases (8.1%) were detected. We found higher incidence in M lesion. Especially 0-Ⅱc with JGCA classification, tubular adenocarcinoma, pT1a (M) detected on lesser curve site were the most popular feature of them. Meanwhile, undifferentiated carcinoma among excavated type and differentiated carcinoma in protruding type was significantly higher incident than another type. Additionally in whole early gastric cancer in this study, excavated type, pT1b2 was identified 30 cases (27.0%) .<br> Conclusions : Sitting on the bedside under the charging medical environment, we reviewed early gastric cancer identified in this private hospital diagnosed by pathologically followed by endoscopic study. From this statistical data, we think that diagnosability of early gastric cancer is affected not only progression of endoscopic device but improvement of circumstance around the hospital including bed number of the hospital and proficiency of endoscopist.
