Aggressive multimodality therapy for malignant pleural mesothelioma.

Nineteen patients with clinical stage I malignant pleural mesothelioma were treated with aggressive multimodality therapy. Nine patients underwent pleurectomy and decortication followed by immediate intrapleural chemotherapy with cisplatin and mitomycin C. Ten patients required pleuropneumonectomy followed within 1 week to 2 weeks by intrapleural administration of cisplatin (100 mg). Four to 8 weeks after operation, 15 patients underwent postoperative adjuvant cisplatin-based systemic chemotherapy. There were three postoperative complications (16%) requiring reoperation and one postoperative death (5%). Intrapleural chemotherapy was well tolerated with no complications. Systemic chemotherapy was poorly tolerated, and there was one chemotherapy-related death. Sixteen patients (84%) experienced good to excellent palliation. Three patients are currently alive with no evidence of recurrent disease at 10, 35, and 43 months. The median overall survival was 13 months and the median disease-free survival, 11 months. Overall and disease-free 3-year survivals were 17% and 22%, respectively. Patients with epithelial malignant pleural mesothelioma had significantly better overall survival (p = 0.037) and disease-free survival (p = 0.02) than patients with sarcomatous or biphasic malignant pleural mesothelioma. We conclude that despite major toxicity, in select patients with clinical stage I malignant pleural mesothelioma, aggressive multimodality therapy offers effective palliation and occasional long-term disease-free survival.
