未分化早期胃癌淋巴结转移风险的回顾性研究

A retrospective study on the risk of lymph node metastasis in undifferentiated early gastric cancer

[目的]探讨未分化型早期胃癌淋巴结转移的潜在危险因素。[方法]回顾性分析82例未分化型早期胃癌患者的临床病理资料,对影响未分化型早期胃癌淋巴结转移潜在危险因素进行单因素及多因素分析。[结果]未分化型早期胃癌淋巴结转移率为15.85%;单因素分析显示,淋巴结转移与肿瘤大小(P=0.046)及脉管癌栓(P=0.018)有关;多因素分析显示脉管浸润栓(P<0.001)是淋巴结转移的危险因素。[结论]肿瘤直径>2 cm或(和)有脉管癌栓的未分化型早期胃癌患者,淋巴结转移风险增加。

[Objective]To explore the potential risk factors affecting lymph node metastasis in undifferentiated early gastric cancer.[Methods]We retrospectively analyzed the clinicopathological data of 82 patients with undifferentiated early gastric cancer,to find out the potential risk factors affecting lymph node metastasis of undifferentiated early gastric cancer Factors and multivariate analysis.[Results]The lymph node metastasis rate in undifferentiated early gastric cancer was 15.85%.Univariate analysis showed that lymph node metastasis was related to tumor size(P=0.046)and vascular tumor thrombus(P=0.018);multivariate analysis.It was shown that vascular infiltration thrombi(P<0.001)was a risk factor for lymph node metastasis.[Conclusion]Patients with undifferentiated early gastric cancer with an area>2 cm or/and vascular tumor thrombi have a higher risk of lymph node metastasis.
