为了探索肺癌患者胸内淋巴结的转移规律，在１１８例肺癌手术中，对同侧胸内淋巴结实施分区清除，分别标记送病理检查。７３例在手术时已有胸内淋巴结转移，占６１．９％。其中仅有Ｎ１转移者２２例（１８．６％），经Ｎ１转移至Ｎ２者３３例（２８．０％），越过Ｎ１转移至Ｎ２者１８例（１５．３％）。距肺根部最近的１１，１０，７，５，４区淋巴结转移频度最高，分别为２９．７％，２７．１％，１５．３％，３０．９％，１７．０％。小细胞肺癌（ＳＣＬＣ）的胸内淋巴结转移率高达８５．７％，明显高于非小细胞肺癌（６０．４％），两者转移率有非常显著性差异，Ｐ＜０．０１。肿瘤的部位、大小和病程与胸内淋巴结转移率的高低无关。
In order to explore the metastatic pattern of chest lymph nodes in patients with lung cancer, in 118 cases of lung cancer surgery, zonal clearance was performed on the same side of the intrathoracic lymph nodes and they were marked for pathological examination. 73 cases had intrathoracic lymph node metastasis at the time of surgery, accounting for 61.9%. Among them, only 22 cases (18.6%) were metastasized to N1, 33 cases (28.0%) were transferred to N2 by N1, and 18 cases (15.3%) were transferred to N2 from N1. The frequency of lymph node metastasis was the highest in the 11th, 10th, 7th, 5th, and 4th regions of the lungs, which were 29.7%, 27.1%, 15.3%, 30.9%, and 17.0%, respectively. The rate of intrathoracic lymph node metastasis in small cell lung cancer (SCLC) was as high as 85.7%, which was significantly higher than that in non-small cell lung cancer (60.4%). There was a significant difference in the metastatic rate between the two groups, P<0.01. The location, size, and course of the tumor were not related to the degree of lymph node metastasis in the chest.
