Core Tip

Core Tip: Early gastric cancer (EGC) refers to adenocarcinoma in which the cancer tissue is limited to the gastric mucosa or submucosa, regardless of tumor size and lymph node metastasis (LNM). It is very important to accurately predict the risk of LNM, and understanding the metastatic status of lymph nodes in EGC is conducive to selecting the appropriate surgical method and improving the overall efficacy of treatment.
