Objective: The objective of this study was to evaluate the impact of the video-assisted thoracoscopic (VATS) approach on the outcomes of patients who underwent pneumonectomy.
Methods: The effect of the surgical approach on perioperative complications and survival in patients who underwent pneumonectomy for nonmetastatic non-small cell lung cancer across 3 institutions (2000-2016) was assessed using multivariable logistic regression, Cox proportional hazards analysis, and propensity-score matching. Completion pneumonectomies were excluded from this study, and an "intent-to-treat" analysis was performed.
Results: During the study period, 359 patients met inclusion criteria and underwent pneumonectomy for nonmetastatic non-small cell lung cancer; 124 (35%) underwent pneumonectomy via VATS and 235 (65%) via thoracotomy. Perioperative mortality (VATS, 7% [n = 9] vs open, 8% [n = 19]; P = .75) and morbidity (VATS, 28% [n = 35] vs open, 28% [n = 65]; P = .91) were similar between the groups, even after multivariable adjustment. VATS showed similar 5-year survival when compared with thoracotomy in unadjusted analysis (47% [95% confidence interval (CI), 36-56] vs 33% [95% CI, 27-40]; P = .19), even after multivariable adjustment (hazard ratio, 0.76 [95% CI, 0.50-1.18]; P = .23). In a propensity score-matched analysis that balanced patient characteristics, there were no significant differences found in overall survival between the 2 groups (P = .69).
Conclusions: Although the role of VATS pneumonectomy will likely become clearer as more surgeons report results, this multicenter study suggests that the VATS approach for pneumonectomy can be performed safely, with at least equivalent oncologic outcomes when compared with thoracotomy.
