    • Abstract

    Background
    The first all Japan multi-institutional trial was completed to evaluate the feasibility of induction chemotherapy using pemetrexed plus cisplatin, followed by extrapleural pneumonectomy (EPP) and postoperative hemithoracic radiation in patients with resectable malignant pleural mesothelioma (MPM). The main results were presented at the ASCO 2013. In this study, we especially reviewed major postoperative complications and mortality of patients who underwent EPP and determined the risk factors responsible for adverse outcomes.

    Methods
    From 2008 to 2010, 42 patients with MPM were enrolled in this study. Thirty-nine patients received planed chemotherapy. Thirty-three patients proceeded to EPP, which was completed in 30 patients. These patients were candidates in this study. Major complications were defined by grade 3, 4, 5 events according to National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0. Treatment-related death was defined as any death occurring within 84 days after operation. Logistic regression analysis was performed on preoperative variables for major adverse outcomes.

    Results
    A total of 17 institutions in Japan with certified specialists in oncology, surgery and radiation therapy participated in this trial. Thirty patients (29 male, 1 female; median age of 66 years, range 43–74) completed EPP (14 right-sided and 16 left-sided), and macroscopic complete resection was accomplished in all patients. Histology of the tumors was epithelial in 22, biphasic in 4, sarcomatous in 1, and others in 3. Median operation time and blood loss were 437 minutes (range, 335-655) and 1461 gram (range, 390-4530), respectively. Major postoperative complications developed in 73.3% of the patients, and treatment-related death occurred in 4 patients (13.3%), which causes were cardiac herniation (n = 1), ARDS (n = 2), bronchial fistula and ARDS (n = 1). There were no significant predictors for major postoperative complications and treatment related death in both univariate and multivariate analysis.

    Conclusion
    We cannot find the predictor of major adverse events and treatment related death in MPM patients treated with induction chemotherapy followed by EPP. Although that is why sample size is small, we also recognize that multimodality treatment including EPP for MPM has more than 10% mortality and should be included in a prospective trial at specialized centers.
