Gastric cancer is a major cancer worldwide but particularly in East Asia, where two-thirds of the cases were reported. This area includes Korea, Japan, and China . Gastrectomy with lymph node dissection has been a standard treatment for gastric cancer . The rationale behind this treatment option is twofold. Small tumors should be excised as they will progress to large tumors and invade other organs. Second, surgical resection of the primary tumors should effectively reduce the risk of metastatic relapse . Outcomes of surgical resection for early stage of gastric cancer are quite good, with a greater than 90% 5-year overall survival, even without adjuvant chemotherapy or radiotherapy . These statistics highlight the important role of surgeons in the treatment of gastric cancer.
