Clinical research of lymph node metastasis rules of non-small cell lung cancer

Objective To analyze the lymph node metastasis rules of non-small cell lung cancer( NSCLC).Methods 112 cases of lung cancer patients were given surgical resection and lymph node dissection of extensive hilar parallel,leaves room and mediastinuml. Pathological data were statistically analyzed. Results A total of 898 groups of lymph nodes were removed. The metastatic rates of N1 and N2( including N1 + N2) nodes were 24. 1%and 30. 4%. There were significant differences in lymph node metastasis existed among primary lung cancer( T)stage T1,T2 and T3( P 0. 01). Solitary metastatic nodes accounted for 35. 3% of N2 metastatic nodes. Conclusion Lymph node metastasis is related with T staging of NSCLC,with more jumping mediastinal lymph node metastasis.There is no significant relationship between tumor location and type of lymph node metastasis. Surgical treatment should pay attention to a wide range of cleaning lungs and ipsilateral mediastinal lymph nodes.
