 To assess the risk factors against lymph node metastasis of submucosal invasive gastric carcinoma, the size, the location, the histological type, the presence of peptic ulcer or ulcer scar, the phenotype by immunohistochemical method, and the depth of invasion of the gastric carcinoma were investigated. The features of submucosal invasive carcinomas with lymph node metastasis were: ( 1 ) large size,( 2 ) located in the lower region of the stomach,( 3 ) lesions containing foci with poorly differentiated adenocarcinoma and papillary adenocarcinoma,( 4 ) lesions accompanied peptic ulcer or ulcer scar,( 5 ) HGM positive finding by immunohistological staining,( 6 ) showing massive invasion of the carcinoma into the deeper submucosal layer. Therefore, if submucosal invasive gastric carcinoma has the above stated features, gastrectomy with lymphadenectomy is recommended.
