    Abstract:
    BACKGROUND: This study assessed perioperative outcome and long-term survival in a large series of patients with malignant pleural mesothelioma who underwent extrapleural pneumonectomy (EPP) to identify prognostic factors allowing better patient selection. METHODS: We retrospectively collected data from nine referral centers for thoracic surgery in Italy. Perioperative outcome and survival data were available for 518 malignant pleural mesothelioma patients (84.4% with epithelial tumors, 68.0% with pathologic stage 3 disease) who underwent EPP with intention-to-treat (R0/R1) between 2000 and 2010. Induction chemotherapy was administered in 271 patients (52.3%) and adjuvant therapy in 373 patients (72.0%), including radiotherapy in 213 patients (41.1%), adjuvant chemotherapy in 43 patients (8.3%), and both in 117 patients (22.6%). RESULTS: In all, 136 patients (26.3%) had major complications after EPP, and 36 (6.9%) died within 90 days after surgery. The median overall survival was 18 months, with a 1-, 2-, and 3-year overall survival of 65%, 41%, and 27%, respectively. At multivariable analysis adjusted for age and disease stage, male sex (hazard ratio [HR] 1.47, 95% confidence interval [CI]: 1.12 to 1.92), nonepithelial histology (HR 1.96, 95% CI: 1.48 to 2.58), and trimodality treatment using induction chemotherapy (HR 0.61, 95% CI: 0.43 to 0.85) were significantly associated with survival. Development of a major complication also significantly worsened outcome (HR 1.85, 95% CI: 1.37 to 2.50). CONCLUSIONS: The success of EPP in the context of a multimodality treatment depends on a series of patient characteristics. Female patients, patients with epithelial tumors, and patients who received induction chemotherapy will best benefit from EPP.
