目的：研究胃周阳性淋巴结数目在胃癌预后中的意义。方法：将１２４例经组织学证实为淋巴结阳性者作为研究对象，分析胃周转移淋巴结数目与临床病理特征及生存率的关系。结果：１２４例胃周淋巴结阳性胃癌患者总的５年生存率为４８．３％，胃周阳性淋巴结超过６个的患者５年生存率明显下降（Ｐ＜０．０１）。与胃周阳性淋巴结≥７个的胃癌相比，阳性淋巴结数≤６个的胃癌常小于４ＣＣ（Ｐ＜０．００５），多呈大体局限型（Ｐ＜０．０２５），未侵及浆膜（Ｐ＜０．０１），巨淋巴结转移多局限于胃周淋巴结（Ｐ＜０．００５）。结论：胃周阳性淋巴结数目与肿瘤进展和生存率相关，是淋巴结阳性胃癌的一个简便有用的预后指标。
Objective: To study the significance of the number of gastric positive lymph nodes in the prognosis of gastric cancer. Methods: 124 cases of histologically confirmed lymph node positive as the research object, analyze the relationship between the number of gastric lymph node metastasis and clinicopathological features and survival rate. Results: The overall 5-year survival rate was 48.3% in 124 patients with gastric lymph node-positive gastric cancer, and 5-year survival rate was significantly decreased in patients with more than 6 gastric lymph nodes (P <0.01). Compared with gastric cancer with positive lymph nodes> 7, the number of positive lymph nodes <6 was less than 4CC (P <0.005), mostly localized (P <0.025) (P <0.01). Metastasis of giant lymph nodes was mostly limited to gastric lymph nodes (P <0.005). Conclusion: The number of gastric lymph nodes positive and tumor progression and survival rate, lymph node positive gastric cancer is a simple and useful prognostic indicators.
