目的:探讨肺癌淋巴结的转移规律。方法:对2004年1月～2006年10月收治的396例肺癌同侧肺门、叶间及纵隔淋巴结广泛廓清手术患者的临床资料进行回顾性分析,比较不同的临床分期(T1、T2、T3、T4)、病理类型(鳞癌、腺癌、其他)、病变部位(中央型、周围型)的患者淋巴结转移率。结果:396例中195例(49.3%)存在N1或(和)N2淋巴结转移,其中单纯N1淋巴结转移44例(11.1%),N2淋巴结转移151例(38.1%);单因素分析结果表明,原发肿瘤分期、原发部位和病理类型均会对肺癌的淋巴结转移率及转移部位有影响(P<0.01)。结论:肺癌容易发生淋巴结转移,淋巴结转移与原发肿瘤分期(T)、原发部位和病理类型均有密切相关。为达到根治目的,提倡纵隔和肺门淋巴结系统清扫。
Objective: To investigate the rule of lymph node metastasis in lung cancer. Methods: The clinical data of 396 patients with extensive resection of hilar, interstitial and mediastinal lymph nodes from January 2004 to October 2006 were retrospectively analyzed. The clinical stage (T1, T2, T3 , T4), pathological types (squamous cell carcinoma, adenocarcinoma, others), lymph node metastasis rate in patients with lesions (central type and peripheral type). Results: There were N1 or (and) N2 lymph node metastases in 195 cases (49.3%) of 396 cases, among them, 44 cases (11.1%) had N1 lymph node metastasis and 151 (38.1%) N2 lymph node metastases. The results of univariate analysis Tumor staging, primary site and pathological type of lymph node metastasis and metastasis of lung cancer have an impact (P <0.01). CONCLUSION: Lymph node metastasis and lymph node metastasis in lung cancer are closely related to the primary tumor stage (T), primary site and pathological type. To achieve the purpose of radical, advocate mediastinal and hilar lymph node system.
