BackgroundTo date, reported surgical morbidity and mortality for pleurectomy/decortication and extrapleural pneumonectomy performed for malignant pleural mesothelioma primarily represent the experience of a few specialized centers. For comparison, we examined early outcomes of pleurectomy/decortication and extrapleural pneumonectomy from a broader group of centers/surgeons participating in the Society of Thoracic Surgeons-General Thoracic Database.MethodsAll patients in the Society of Thoracic Surgeons-General Thoracic Database (version 2.081, representing 2009-2011) who underwent pleurectomy/decortication or extrapleural pneumonectomy for malignant pleural mesothelioma were identified. Patient characteristics, morbidity, mortality, center volume, and procedure were examined using univariable and multivariable analyses.ResultsA total of 225 patients underwent pleurectomy/decortication (n = 130) or extrapleural pneumonectomy (n = 95) for malignant pleural mesothelioma at 48 centers. Higher volumes of procedures (≥5/y) were performed at 3 pleurectomy/decortication and 2 extrapleural pneumonectomy centers. Patient characteristics were statistically equivalent between pleurectomy/decortication and extrapleural pneumonectomy groups, except those undergoing extrapleural pneumonectomy were younger (63.2 ± 7.8 years vs 68.3 ± 9.5 years; P < .001) and more likely to have received preoperative chemotherapy (30.1% vs 17.8%; P = .036). Major morbidity was greater after extrapleural pneumonectomy, including acute respiratory distress syndrome (8.4% vs 0.8%; P = .005), reintubation (14.7% vs 2.3%; P = .001), unexpected reoperation (9.5% vs 1.5%; P = .01), and sepsis (4.2% vs 0%; P = .03), as was mortality (10.5% vs 3.1%; P = .03). Multivariate analyses revealed that extrapleural pneumonectomy was an independent predictor of major morbidity or mortality (odds ratio, 6.51; P = .001). Compared with high-volume centers, increased acute respiratory distress syndrome was seen in low-volume centers performing extrapleural pneumonectomy (0% vs 12.5%; P = .05).ConclusionsExtrapleural pneumonectomy is associated with greater morbidity and mortality compared with pleurectomy/decortication when performed by participating surgeons of the Society of Thoracic Surgeons-General Thoracic Database. Effects of center volume require further study.Copyright © 2014 The American Association for Thoracic Surgery. All rights reserved.
