目的研究原发肺鳞癌及腺癌纵隔淋巴结转移特点,探讨临床意义。方法对353例原发肺癌施行同侧纵隔淋巴结廓清术,病理检测淋巴结转移频度。结果清除淋巴结2380组,平均每例6.74组。N2淋巴结转移率16.2%。T1、T2、T3间淋巴结转移率差异有统计学意义(P<0.01)。N2转移率在鳞癌、腺癌分别为30.1%、44.1%。64.2%鳞癌N2转移为某一组淋巴结,腺癌3组以上转移者46.2%。上叶肺癌跨区域N2转移占15.1%,下叶(包括中叶)肺癌跨区域转移占53.1%。跳跃式转移占N2转移的53.7%。结论肺鳞癌及腺癌纵隔淋巴结转移具有多发性、跳跃性及跨区域性特点。
Objective To study the characteristics of primary lung squamous cell carcinoma and adenocarcinoma with mediastinal lymph node metastasis and to explore its clinical significance. Methods 353 cases of primary lung cancer ipsilateral mediastinal lymph node dissection, pathological lymph node metastasis frequency. Results 2380 lymph nodes were removed, with an average of 6.74 in each group. N2 lymph node metastasis rate of 16.2%. The difference of lymph node metastasis rate between T1, T2 and T3 was statistically significant (P <0.01). N2 metastasis in squamous cell carcinoma, adenocarcinoma were 30.1%, 44.1%. 64.2% squamous cell carcinoma N2 metastasis was a group of lymph nodes, adenocarcinoma more than 3 groups of 46.2% metastasis. Upper lung cancer transplanted to N2 accounted for 15.1% of lung metastases, and lower lungs (including middle lobes) accounted for 53.1% of lung metastases. Jump transfer accounted for 53.7% of N2 transfer. Conclusions The mediastinal lymph node metastasis of lung squamous cell carcinoma and adenocarcinoma is characterized by multiple, leaping and trans-regional features.
