Radical surgery for malignant pleural mesothelioma: results and prognosis.
The role of surgical treatment for malignant pleural mesothelioma (MPM) continues to be controversial. We carried out a retrospective review of the prognosis in patients who had radical surgery for MPM. Of 87 consecutive patients on whom surgical exploration for biopsy-proven MPM was performed, 31 patients underwent extrapleural pneumonectomy (EPP) and 34 patients underwent pleurectomy/decortication (P/D). Sixty-five patients having EPP or P/D included 58 men (89%). The median age was 60 years (range 35-78) and the histologic type was epithelial in 48 patients (74%). IMIG staging classification was p-stage I disease in eight patients (12%), p-stage II in 13 (20%), p-stage III in 40 (62%) and p-stage IV in 4 (6%). Operative mortality was 3.2% for EPP and none for P/D. The median and 3-year survivals after EPP were 13 months and 33% whereas those after P/D were 17 months and 24%, respectively. A multivariate analysis demonstrated that older age (P=0.0467), non-epithelial histology (P=0.0057) and p-stage III-IV disease (P=0.0019), but not gender, side, surgical procedure, were significant independent negative prognostic factors. Although P/D appears to be acceptable in early stages, we encourage EPP, en bloc resection without entering the pleural cavity with intent for curability, which provides oncologically complete resection of all disease.
