摘 要: | 目的 分析肺腺鳞癌淋巴结转移(LNM)的特点.方法 对361例肺腺鳞癌患者的临床资料进行回顾性分析.淋巴结分区和TNM分期采用国际抗癌联盟(UICC)标准(1997年).统计分析采用χ2检验、Log rank检验和Cox比例风险模型分析.结果 361例肺腺鳞癌纵隔LNM途径表现为:左肺上叶癌首先转移到主.肺动脉窗淋巴结,右肺上叶癌首先转移到下气管旁淋巴结,两侧下叶肺癌首先转移到隆突下淋巴结,右肺中叶肺癌以向上转移为主.纵隔淋巴结跳跃转移以隆突下最为多见,其次为主-肺动脉窗和下段气管旁.发生单一站纵隔淋巴结跳跃转移的患者预后好于其他LNM者.结论 不同部位肺腺鳞癌的LNM途径和跳跃转移部位有所不同,治疗时应加以考虑.不同转移模式的患者预后不同,发生单一站纵隔淋巴结跳跃转移的患者预后可能较好.

Abstract: | Objective To investigate the rule of lymph node metastasis of adenosquamous carcinoma of the lung. Methods The data of 361 surgically treated patients with edenosquamous carcinoma of the lung from October 1965 to June 2003 were collected and retrospectively reviewed. The classification of regional lymph node stations and TNM stage were determined according to the UICC criteria (1997). The mute and patterns as well as influencing factors of lymph node metastasis were analyzed by SPSS 10.0 software. The median follow-up period was 5.5 years (range, 1.4 to 23.4 years). Results The analysis of the route of mediastinal lymph node metastasis in the 361 cases showed that the tumor originated in the left upper lobe firstly metastasized to station 5 (A-P window), tumor in the right upper lobe to the station 4 (lower paratracheal), then secondly to station 7 (subcarinal), lastly to station 3 from the tumor in the left upper lobe or to the station 2 from the tumor in the right upper lobe. It was found that the tumors originated from the lower lobe, firstly metastasized to station 7, secondly to station 9 or 4 from the right lobe; or station 5 from left lower lobe, lastly to station 3 or 2 in the mediastinum. For the tumor in the middle lobe, mainly metastasized to station 7, 4 and 2. The skip mediastinal lymph node metastasis but N1 negative most commonly metastasized to station 7, then to station 4 from the tumor in the right lung and 5 from the tumor in the left lung. The prognosis of patients with a single skipping metastasis to mediastinal lymph node(N1-,SMLN) was better than that in the other patients with mediastinal lymph node metastases. Conclusion The lung cancer growing in a different location has a different route and skipping metastasis to mediastinal lymph nodes. The patterns of lymph node metastasis affect prognosis. The prognosis of patients with single skipping metastasis to mediastinal lymph nodes but negative pulmonary hilar lymph node is better than that in the other patients with multiple station mediastinal lymph node metastases. The "NI-, SMLN" pattern ought to be considered as a special lymph nodal metastasis with better prognosis. |
