INTRODUCTION: Multimodality treatment has achieved significant success in local control and treatment of early-stage malignant pleural mesothelioma patients. However, its favorable effect on survival is questionable. METHODS: We have instituted a trimodality treatment protocol consisting of extrapleural pneumonectomy, adjuvant high-dose (54 Gy) hemithoracic irradiation, and platin-based chemotherapy in a multi-institutional setting. Preoperative pulmonary function tests, echocardiogram, chest computed tomography, and magnetic resonance imaging scans were performed in all patients. Twenty patients have been treated with this protocol during 2003-2007. Seventeen had a history of environmental asbestos/erionite exposure. Clinical stages were T1-3N0-2. RESULTS: Median age was 56 (41-70, 8 female). There was one postoperative mortality (% 5) due to ARDS. Morbidity occurred in 11 patients (% 55). Histology was epithelial in 17, mixed in 2, and sarcomatoid in 1. Sixteen patients underwent extrapleural pneumonectomy. Microscopic margin positivity was present in 14 patients with macroscopic complete resection. Twelve patients completed all three treatments. Median follow-up was 16 months (1-43). Overall median survival was 17 months (24% at 2 years). Eight patients had extrapleural lymph node involvement (internal mammary [n = 3], subcarinal [n = 2], pulmonary ligament [n = 1], diaphragmatic [n = 1], subaortic [n = 1]). There was better survival in patients without lymph node metastasis (24 versus 13 months median survival, p = 0.052). Currently, 7 patients are alive, 6 without recurrence, and 2 patients at 40 and 45 months. CONCLUSIONS: Trimodality treatment in malignant pleural mesothelioma seems to prolong survival in patients without lymph node metastasis. Novel techniques are needed for preoperative assessment of extrapleural lymph nodes.

P/D v. EPP: results in 663 patients

March 12, 2008

OBJECTIVE: The optimal procedure for resection of malignant pleural mesothelioma is controversial, partly because previous analyses include small numbers of patients. We performed a multi-institutional study to increase statistical power to detect significant differences in outcome between extrapleural pneumonectomy and pleurectomy/decortication.

METHODS: Patients with malignant pleural mesothelioma who underwent extrapleural pneumonectomy or pleurectomy/decortication at 3 institutions were identified. Survival and prognostic factors were analyzed by the Kaplan-Meier method, log-rank test, and Cox proportional hazards analysis.

RESULTS: From 1990 to 2006, 663 consecutive patients (538 men and 125 women) underwent resection. The median age was 63 years (range, 26-93 years). The operative mortality was 7% for extrapleural pneumonectomy (n = 27/385) and 4% for pleurectomy/decortication (n = 13/278). Significant survival differences were seen for American Joint Committee on Cancer stages 1 to 4 (P < .001), epithelioid versus non-epithelioid histology (P < .001), extrapleural pneumonectomy versus pleurectomy/decortication (P < .001), multimodality therapy versus surgery alone (P < .001), and gender (P < .001). Multivariate analysis demonstrated a hazard rate of 1.4 for extrapleural pneumonectomy (P < .001) controlling for stage, histology, gender, and multimodality therapy.

CONCLUSION: Patients who underwent pleurectomy/decortication had a better survival than those who underwent extrapleural pneumonectomy; however, the reasons are multifactorial and subject to selection bias. At present, the choice of resection should be tailored to the extent of disease, patient comorbidities, and type of multimodality therapy planned.
