Abstract　The main risk factors of lymph node metastasis in early gastric cancer include tumor size, depth of invasion, lymphaticinvasion, perineural invasion, differentiation and histological manifestations. Understanding the characteristics and regularity of lymph node metastasis in early gastric cancer is helpful to evaluate the prognosis of patients, and it can also provide more choices for their treatment, which has important clinical guiding significance. Gastrectomy should be performed for patients with preoperative staging or highly suspected lymph node involvement in order to resect the tumors and select a reasonable range of lymph node dissection.

Key words: early gastric cancer, lymph node metastasis, prognosis

摘要：

早期胃癌淋巴结转移的主要危险因素包括肿瘤大小、浸润深度、淋巴管浸润、神经浸润、分化程度及组织学表现。了解早期胃癌淋巴结转移特点及规律有助于评估病人预后，为其治疗提供更多选择，具有重要临床指导意义。对于术前分期发现或高度怀疑有淋巴结受累的病人，应行胃切除术以切除肿瘤和适当选择合理的淋巴结清扫范围。
