Abstract

Objectives: To assess the results of lymph node dissection in patients with non-small cell lung cancer undergoing video-assisted thoracic surgery (VATS) lobectomy with lymph node dissection. Methods: A retrospective, cross-sectional descriptive study was conducted on 73 patients with non-small cell lung cancer undergoing VATS lobectomy and lymph node dissection at Military Hospital 103 from January 2022 to December 2024. Results: The rate of lymph node metastasis was 26.1%, N1 lymph node metastasis was 11.0%, N2 lymph node metastasis was 11.0%, N1 and N2 metastasis was 4.1%. The rate of lymph node metastasis in females was higher than that in males (30.0% and 24.5%). The age group > 60 was higher than the group ≤ 60 (27.1% and 24%); the group with visceral pleura invasion (36.4%) was higher than the group without visceral pleural invasion; the group with adenocarcinoma (26.2%) was higher than the group with squamous carcinoma (25.0%), the difference was not statistically significant. The central tumor had lymph node metastasis (44.0%), higher than the peripheral tumors (16.7%); the difference was statistically significant with p = 0.003. Conclusion: There was no correlation between age, gender, size, and histological type of the primary tumor on lymph node metastasis. The tumor location in the central lung lobe had a higher rate of lymph node metastasis than the peripheral tumor.
