BackgroundThere is a lack of large, prospective, randomized studies comparing thoracoscopic and open lobectomy in terms of long-term survival in the setting of NSCLC. Additionally, large case series evaluating the issue are limited. Until now, whether thoracoscopic lobectomy entails a long-term survival benefit compared with open lobectomy not been determined.MethodsData were obtained from the National Health Insurance Research Database published in Taiwan. We included patients treated with open lobectomy or thoracoscopic lobectomy. In this retrospective review, the clinicopathologic characteristics of 5222 patients with lung cancer during the period 2004-2010 were analyzed. Patients were stratified according to clinical stage. Overall survival (OS) was compared between patients treated with open and those treated with thoracoscopic lobectomy and was also compared between patients in the three different clinical stages. Propensity-matching analysis and multivariate analysis were performed.ResultsOpen lobectomy was performed on 3058 patients (58.6%) and thoracoscopic lobectomy on 2164 (41.4%). Propensity matching produced 1848 patients in each group. The 1-year, 3-year, and 5-year OS rates for propensity-matched patients treated with open lobectomy were 93.4%, 79.3%, and 65.5%, respectively. The 1-year, 3-year, and 5-year OS rates for propensity-matched patients treated with thoracoscopic lobectomy were 94.1%, 80.9%, and 68.7%, respectively. The difference was not statistically significant. In multivariate analysis, surgical resection (open versus thoracoscopic) was not an independent prognostic factor.ConclusionsThis propensity-matched study suggests that open and thoracoscopic lobectomy are associated with similar long-term survival in the setting of lung cancer. Thoracoscopic lobectomy is an acceptable surgical treatment of lung cancer.Copyright © 2016 International Association for the Study of Lung Cancer. Published by Elsevier Inc. All rights reserved.
