Gastric cancer is the leading cause of cancer death in Korea. The high mortality rate of gas- tric cancer is partly attributed to its late detection and the perfomance of surgery at an advanced stage of disease. So, its early detection and treatment of gastric carcinoma will im- prove the current unfavourable prognosis of gastric cancer. Progress in diagnostic endoscopy has made it possible to detect the early gastric cancer which has excellent postoperative out- come because of its high curability. In this retrospective study, 181 cases of early gastric cancer which have been resected at the Korea University Anam Hospital from January, 1982 to December 1992 were reviewed with emphasis on incidence, macroscopic classification, clinical significance, and prognosis in order to elucidate the clincal picture of early gastric cancer. The proportion of early gastric cancer was 8.1% of all gastric cancer and 0.29% of total patients who underwent gastrofiberscopy. The ratio of male to female was 1.8: 1, and the peak age of incidence was 6th decade(35.4%). The lesion was most commonly found in antrum(51.1%) and lesser cur- vature side(73.1%). EGC type II< was the most common macroscopic type(31.3%). The size of lesion was mostly less than 3cm(68.1%) and the larger lesions showed the higher rate of in- vasion to submucosa and lymph node metastasis. The percentage of lymph node metastasis was much higher in lesion infiltrating to submucosa(20.0%) than mucosa confined cancer. According to cancer cell type, tubular adenocarcinoma was most common(74.8%). There was no correlation between cancer cell type and the incidence of lymph node metastasis. The diag- nostic accuracy by gastrofiberscopic observation was 83.5%. The 5 year survival rate of total early gastric cancer patient was 94.2%.(Korean J Gastroenterol 1994; 26: 789 799)
