Core Tip

Core tip: Early gastric cancer (EGC) is defined as invasive gastric cancer that invades no more deeply than the submucosa, irrespective of lymph node metastasis. Gastrectomy/endoscopic resection can be used for the treatment of patients meeting appropriate criteria. In this study, we retrospectively evaluated the relationship between lymph node metastasis and clinical pathological features of 525 EGC cases. Univariate and multivariate analyses were applied to confirm the risk factors for lymph node metastasis, and to establish indications for a feasible individualized endoscopic therapy for EGC.
