Screening endoscopy in Japan and Korea have substantially increased the rate of early gastric cancer (EGC) in approximately 50% when the corresponding rate in the West ranges between 10 and 20% of all gastric cancers . This high proportion of EGC in East Asia has led to the development of endoscopic mucosal resection (EMR) technique that dramatically improves quality of life (QOL) [2-4]. Recently, rigorous recommendations from Japan have established criteria for EMR to prevent local and nodal recurrences . Signet ring cell carcinoma (SRC) or undifferentiated cancers have not been included in the indications for EMR . SRC corresponds to the diffuse type gastric cancer according to Lauren classification, which in contrast to the intestinal type cancer, requires wider excision margins for histologically free resection margins and prevention of local and nodal recurrence [6, 7].
