目的分析非小细胞肺癌纵隔淋巴结转移的方式和规律,以探讨非小细胞肺癌纵隔淋巴结合理的手术清扫范围。方法对60例非小细胞肺癌患者行手术并给予纵隔淋巴结清扫,回顾性分析病理证实的转移纵隔淋巴结分布情况。结果手术共清扫324组纵隔淋巴结,平均每例清扫6.2组,病理证实有癌细胞转移的110组,转移率为34%。结论上叶癌以上纵隔淋巴结转移居多,中、下叶癌则上、下纵隔均可发生转移。淋巴结转移具有跳跃性和多发性。只有广泛清扫纵隔淋巴结才有可能达到根治,否则被视为非根治。
Objective To analyze the mode and rule of mediastinal lymph node metastasis in non-small cell lung cancer (NSCLC) to explore the range of surgical dissection of mediastinal lymph node in non-small cell lung cancer. Methods Sixty patients with non-small cell lung cancer underwent surgery and mediastinal lymph node dissection. The distribution of metastatic mediastinal lymph nodes confirmed by pathology was retrospectively analyzed. Results A total of 324 mediastinal lymph nodes were dissected, with an average of 6.2 in each group. There were 110 metastatic cancer cells in the pathology group and the metastasis rate was 34%. Conclusion The majority of mediastinal lymph nodes metastasis above the upper lobe, middle and lower lobe cancer, the upper and lower mediastinal metastasis can occur. Lymphatic metastasis with jumping and multiple. Only radical dissection of mediastinal lymph nodes can achieve radical cure, otherwise it is considered non-cure.
