Core Tip
Core tip: We aimed to re-evaluate and verify the current indications and guidelines for endoscopic treatment and to analyze the clinicopathological predictors of lymph node metastasis in early gastric cancer (EGC), which have been inconsistently identified across studies. To the best of our knowledge, this study involves the largest number of EGC patients in China, and is the first study to perform statistical analyses on certain clinical features, such as drinking, smoking, obesity, family history of tumors, and tumor markers.
