Core Tip
Core Tip: Gastric carcinogenesis occurs mostly de novo. Superficial gastric tumors can be roughly divided into the APC mutation type and the TP53 mutation type, which are mutually exclusive. APC-type tumors have low malignancy and develop into low-grade dysplasia, whereas TP53-type tumors have high malignancy and are considered cancerous even if they are small. For lesions diagnosed as category 3 or 4 in the Vienna classification system, endoscopic submucosal dissection and staging should be performed. If the tumor is diagnosed with lymphovascular or submucosal invasion, additional surgical treatment of gastrectomy with lymph node dissection is required.
