  • Abstract
  • Look Inside

 We examined 159 cases of gastric sm-cancers obtained by surgical resection and 15 cases by endoscopic mucosal resection (EMR). As a result, the characteristics of sm-cancers without lymph node metastasis are as follows; 1) Diameter is less than 1 cm. 2) Histologically differentiated and not accompanied with undifferentiated elements. 3) Microscopically minute invasion, and 4) No lymphatic invasion. Therefore, we agree that sm-cancers are curable by using EMR, on condition that clinically they are intramucosal, resected en bloc, and that they are histologically differentiated lesions. But we can't agree that EMR is an effective cure for those clinically detectable sm-cancers not fulfilling the conditions mentioned above.
