Abstract

Objectives: To find out the lymph node metastasis depended on tumor characteristics in non-small cell lung cancer patients post thoracoscopic lobectomy and lymph node dissection. Subjects and methods: A prospective and descriptive study on lymph node metastasis status following tumor signs in 98 lung cancer patients with I - IIIA stage who underwent thoracoscopic lobectomy and lymph node dissection at 108 Military Central Hospital from 5/2017 - 3/2021. Results: Lymph node metastasis rate was 30.6%; the rate of lymph node metastasis to the superior mediastinal region of the upper lobe tumor was 15.2%; the rate of lymph node metastasis to the inferior mediastinal region of the lower lobe tumor was 31.4%. In the tumor diameter ≥ 5 - 7 cm group, the N1 lymph node metastasis accounted for the highest proportion (25.0%), and the N2 lymph node metastasisis rate was 29.6% in  the tumor diameter ≥ 3 - 5 cm group. In the tumor invasion group, the N2 lymph node metastasis proportion made up 26.5%. Conclusion: The lymph node metastasis is related to tumor location and tumor size. The tumor invasion tends to be related to lymph node metastasis.
