- Abstract
<bold>Purpose: </bold>To investigate the short-term outcomes and long-term oncological efficacy of video-assisted thoracic surgery (VATS) for surgical treatment of pN2 non-small cell lung cancer (NSCLC) compared with open thoracotomy (OT).<bold>Patients and Methods: </bold>We retrospectively collected data from 1034 patients who underwent pulmonary resection and systemic lymph node dissection for pathological N2 NSCLC from September 2005 to December 2017 (536 patients in VATS group and 498 patients in OT group). Propensity score matching was applied to reduce the confounding effects. Factors affecting survival were assessed by Kaplan-Meier estimates and Cox regression analysis.<bold>Results: </bold>The VATS procedure was associated with shorter operative time compared with the OT procedure (147.96 ± 58.91 min vs. 165.34 ± 58.91 min, P < 0.001). No significant difference was identified between the two groups in the number of dissected mediastinal lymph nodes (MLNs) and number of dissected MLNs stations. More patients after VATS procedure received postoperative adjuvant therapy (83.4% vs. 75.5%, P = 0.002). At a median follow-up of 36 (range 4-150) months, comparing VATS procedure and OT procedure, no significant differences were noted in 5-year DFS (20.7% vs. 22.5%, P = 0.89) and 5-year OS (30.7% vs. 34.5%, P = 0.821). The VATS procedure was not found to be an independent predictor of DFS (hazard ratio, 0.986; 95% CI, 0.809 to 1.202) or OS (hazard ratio, 0.977; 95% CI 0.802 to 1.191).<bold>Conclusion: </bold>In this large propensity-matched comparison, the VATS procedure offered comparable short-term outcomes and long-term oncological efficacy for patients with pN2 NSCLC when compared with OT procedure.
