[目的]探讨肺癌患者发生淋巴结转移的规律及影响淋巴结转移的因素。[方法]对既往行肺癌根治性切除术治疗的209例患者进行回顾性分析,对发生淋巴结转移的分布规律及其影响因素进行统计分析。[结果]209例患者,共清扫淋巴结974枚,其中发生淋巴结转移223枚(22.90%),发生淋巴结转移的患者有81例(38.76%)。淋巴结转移率较高的组分别为第11组(30.43%)、第4组(28.00%)、第3组(27.45%),淋巴结转移率较低的组分别为第9组(10.59%)、第1组(14.71%)、第8组(16.00%)。肿瘤的病理类型为腺癌(OR=1.892)、中央型肺癌(OR=1.528)、低分化程度(OR=1.633)是肺癌患者发生淋巴结转移的危险因素(P<0.05),与患者是否吸烟关系不密切(P>0.05)。[结论 ]淋巴结转移主要与病理类型、病灶部位、分化程度有关,淋巴结转移规律分析有利于为手术患者术中扫除淋巴结和放疗患者靶区规划提供参考依据。
[Objective] To investigate the regularity of lymph node metastasis and the factors affecting lymph node metastasis in patients with lung cancer. [Methods] A total of 209 patients with previous radical resection of lung cancer were retrospectively analyzed. The distribution of lymph node metastasis and its influencing factors were statistically analyzed. [Results] A total of 974 lymph node dissections were performed in 209 patients, of which 223 (22.90%) had lymph node metastasis and 81 (38.76%) had lymph node metastasis. The patients with higher lymph node metastasis rate were group 11 (30.43%), group 4 (28.00%), group 3 (27.45%) and group with lower lymph node metastasis rate (group 9, 10.59% Group 1 (14.71%), Group 8 (16.00%). The pathological types of the tumors were adenocarcinoma (OR = 1.892), central lung cancer (OR = 1.528), poorly differentiated (OR = 1.633), a risk factor for lymph node metastasis in patients with lung cancer (P <0.05) Not close (P> 0.05). [Conclusion] Lymph node metastasis is mainly related to the pathological type, lesion location and differentiation degree. The analysis of lymph node metastasis is helpful to provide a reference for the planning of target area in patients with lymph node dissection and radiotherapy during operation.
