AbstractIn lobectomy of patients with lung cancer, the principle of operation is to cut off the pulmonary vein first, but it is often not taken seriously in clinical practice. We conducted this research to compare the impact of different sequences of pulmonary vessel ligation on the long-term survival of patients. This cohort study included 1239 patients treated surgically with video-assisted thoracoscopic lobectomy from January 2015 to December 2019 at The Second Affiliated Hospital of Nanchang University. Survival and perioperative indicators were compared between a Vein-first group (VF) and an artery-first group. After matching, 364 patients were included in each group for analysis. VF was associated with better overall survival (hazard ratio: 1.96 [1.4~2.74], P < .0001) and disease-free survival (hazard ratio: 1.65 [1.22~2.24], P = .0011). Meanwhile, the survival advantage of VF was achieved in almost all subgroups, particularly in the pathological tumor node metastasis stage I-II group and squamous cell carcinoma group. We obtained no significant differences in perioperative indications (operation time, hospital stay, etc) between VF and artery-first group. With better overall survival and disease-free survival, especially for pathological stage I-II squamous cell carcinoma, vein-first ligation should be strictly observed in lobectomy for patients with non-small cell lung cancer.Copyright © 2023 the Author(s).
