早期非小细胞肺癌淋巴结转移规律及清扫方式研究进展

Lung cancer is the malignant tumor with the highest morbidity and mortality in China. Non-small cell lung cancer is the main pathological type. Lymph node metastasis is the most common and primary metastatic pathway in non-small cell lung cancer. Acknowledged as the major factor determining tumor staging and prognosis. Unfortunately, it' s presently hard to make an accurate preoperative judgment on the lymph node metastasis of early stage non-small cell lung cancer. Consequently, there has been a long-standing controversy on lymph node sweeping for early stage non-small cell lung cancer, especially for those clinical stage Ⅰ. The regularity of non-small cell lung cancer lymph node metastasis and the ways of lymph node sweeping will be reviewed in this paper.
