Abstract
Objective: To find out some characteristics of lymph node metastasis in non-small cell lung cancer patients. Subject and method: Eighty patients who had undergone thoracoscopic lobectomy and lymph node resection from July 2017 to July 2019. Statistics of primary tumor lesions and lymph node metastases in thirsty patients who had lymph node metastasis. Analyze the relations between the tumor characteristics and lymph node metastases. Result: The patients with lymph node metastasis was identified in 32 (38.1%); the rate of N1 metastasis was 14.3%, N1 and N2 stage metastasis was 8.3%, and skip metastasis was 15.5%. The rate of lymph node metastasis by tumor size: Tumor < 3cm 25.9%, tumor > 3cm and < 5cm 59.3%, tumor > 5cm and < 7cm 66.7%. The rate of metastasis by invasive lesion: Non-invasion 36.8%, visceral pleura invasion 43.5%, parietal pleura invasion 25.0%. Conclusion: Lymph node metastasis in non-small cell lung cancer was accounted for a high proportion; lymph node metastasis properties were associated with primary tumor size
