Abstract

Background: Whether extrapleural pneumonectomy (EPP) or extended pleurectomy/decortication (P/D) is the optimal resection for malignant pleural mesothelioma remains controversial. We therefore compared perioperative outcomes and long-term survival of patients who underwent EPP versus P/D. Methods: Patients with the diagnosis of malignant pleural mesothelioma who underwent either EPP or P/D from 2000 to 2019 were identified from our departmental database. Propensity score matching was performed to minimize potential confounders for EPP or P/D. Survival analysis was performed by the Kaplan-Meier method and Cox multivariable analysis. Results: Of 282 patients, 187 (66%) underwent EPP and 95 (34%) P/D. Even with propensity score matching, perioperative mortality was significantly higher for EPP than for P/D (11% vs 0%; P = .031); when adjusted for perioperative mortality, median overall survival between EPP and P/D was 15 versus 22 months, respectively (P = .276). Cox multivariable analysis for the matched cohort identified epithelioid histology (hazard ratio [HR], 0.56; P = .029), macroscopic complete resection (HR, 0.41; P = .004), adjuvant radiation therapy (HR, 0.57; P = .019), and more recent operative years (HR, 0.93; P = .011)—but not P/D—to be associated with better survival. Asbestos exposure (HR, 2.35; P = .003) and pathologic nodal disease (HR, 1.61; P = .048) were associated with worse survival. Conclusions: In a multimodality treatment setting, P/D and EPP had comparable long-term oncologic outcomes, although P/D had much lower perioperative mortality. The goal of surgical cytoreduction should be macroscopic complete resection achieved by the safest operation a patient can tolerate.
