目的 探讨早期胃癌的淋巴结转移规律及其对预后的影响。方法 对161例有癌病人术后进行长期随访，对24例伴有淋巴结转移的早期胃癌与137例无淋巴结转移的早期胃癌的临床病理特征及3、5年生存率进行比较。结果 早期胃癌的淋巴结转移与肿瘤大小、浸润深度及淋巴、静脉侵犯有关，伴有淋巴结转移的早期胃癌3、5年生存率分别为82.8%和80.5%，明显低于无淋巴结转移者，后者分别为96.1%和92.4%。结论 术前或术中正确评估早期胃癌的淋巴结转移状态是选择合理的治疗方案和改善预后的重要条件。

Lymph node metastasis and prognosis in early gastric cancer

Objective To explore the general pattern of lymph node metastasis and its effect on prognosis in early gastric cancer.Methods After surgery 161 patients with early gastric cancer were followed up for a long time.The clinicopathologic features and the 3- and 5-year survival rates of 24 patients with node-positive early gastric cancer were compared with those of 137 patients with node-negative early gastric cancer.Results The tumor size,depth of invasion,and lymphatic and venous involvement were related to lymph node metastasis in early gastric cancer.The 3- and 5-year survival rates of patients with node-positive early gastric cancer were 82^8% and 80^5% respectively,which were significantly lower than those of patients with node-negative early gastric cancer,96^1% and 92^4% respectively.Conclusion Precise evaluation of lymph node metastasis pre- or intraoperatively is essential for therapeutic options and prognosis improvement in early gastric cancer.
