Abstract
We analyzed 445 cases of early gastric cancer to confirm which were associated with lymph-node metastases. Overall, gastric cancers less than 2 cm in size, without an ulcer or ulcer scar, or protuberant or mixed morphology could be expected to be free of lymph-node metastases. In these patients with early gastric cancer without lymph-node metastasis, local treatment using surgical endoscopy could effectively eradicate the disease. Laser irradiation was performed in 44 cases and mucosal resection in 18 cases. All early gastric cancers less than 2 cm in size, with the exception of those located in the prepylorus or high on the posterior wall of the body of the stomach were eradicated by laser irradiation. Mucosal resection was used to ablate cancers less than 1 cm in size and with the exception of 1 case, total clearance was obtained. We conclude that early gastric cancer without lymph-node metastases can be eradicated by surgical endoscopic treatment.
