T1期非小细胞肺癌纵隔淋巴结转移规律及清扫方式研究进展

Lung cancer ranks the frst position in morbidity and mortality among all malignances in China. Nonsmall cell lung cancer (NSCLC) accounts for nearly 80% of all lung malignancies. Surgical resection is still the current major treatment method for early stage NSCLC. Lymph node stages together with the extent of lymph node dissection directly a?ect the prognosis. Te site of primary lung carcinoma may a?ect the route and status of lymph node metastasis. Up to now, anatomical lobectomy and mediastinal lymph node dissection is deemed to be the standard surgical treatment for NSCLC. However, it is still controversial in the extent of lymph node dissection for T1 NSCLC. More and more surgeons intend to perform selective mediastinal lymph node dissection instead of complete mediastinal lymph node dissection for T1 NSCLC in recent years.
