Objective: To report on the experience with radical surgery, with emphasis on the long-term outcome, for malignant pleural mesothelioma (MPM) at a single institution., Methods: From our prospective database over a 17-year period, we reviewed 83 consecutive patients undergoing radical surgery for MPM in a multimodality programme. The long-term overall survival was analysed using the Kaplan-Meier method., Results: A total of 83 patients (65 males, median age: 60 years) underwent an extra-pleural pneumonectomy (EPP) with a curative intent. Epitheliod MPM was the most frequent (82%) cause. A right-sided disease was present in half of the cases (n=42). The International Mesothelioma Interest Group (IMIG) stage of the disease was 2 in 36%, 3 in 45% and 4 in 9% of the cases. Preoperative chemotherapy consisting of a doublet cisplatin-pemetrexed (mean of three cycles) was offered to 10 patients (12%). Postoperative therapies, either chemotherapy or radiotherapy, were given in 25 patients (30%). The 30-day and 90-day mortality rates were 4.8% and 10.8%, respectively. Postoperative complications occurred in 39.8% and were major in 23 patients (27.7%). Re-operation was necessary in 12 cases (14.5%) for one of the following reasons: broncho-pleural fistula (n=4), bleeding (n=3), diaphragmatic patch rupture (n=3), oesophago-pleural fistula (n=1) and empyaema (n=1). The mean hospital stay was 43 days. The median survival was 14.5 months, while the overall 1-, 2- and 5-year survival rates were 62.4%, 32.2% and 14.3%, respectively., Conclusions: These results concur with the published data of the most experienced centre with regards to the mortality and morbidity after EPP for MPM. In line with the biggest series reported in the past, the observed 5-year survival rate of almost 15% is disappointing.

Abstract: Objective: To identify the optimal debulking procedure in patients with malignant pleural mesothelioma who are not suitable for extrapleural pneumonectomy (EPP). Methods: We reviewed 102 consecutive patients (93 male; 9 female, mean age 63 years) who were not suitable for EPP because of either advanced tumour stage or suboptimal fitness. Patients underwent either a non-radical tumour decortication to obtain lung expansion (group NR) or latterly a radical pleurectomy/decortication to obtain macroscopic tumour clearance (group R). We analysed the comparative perioperative courses and long-term survival. Results: The two groups were similar for age and gender distribution but epithelioid type was more predominant in group R: 78% compared to 55% epithelioid in group NR. Thirty-day mortality was similar (5.9% in group R and 9.8% in the group NR, p =0.36) but 90-day mortality was significantly higher in the group NR (29.4% vs 9.8% in group R, p =0.012). More patients in group R received adjuvant chemotherapy (65% vs 28%, p =0.000) and radiotherapy (65% vs 26%, p =0.000). Median survival for all cell types was significantly higher in group R (15.3 months vs 7.1 months, p <0.000). Group R survival rates at 1, 2, 3 and 4 years were 53, 41, 25 and 13%, respectively while for group NR they were 32, 9.6, 2 and 0%, respectively. For epithelioid cell type there was still a significant median survival advantage in group R (25.4 months vs 10.2 months, p <0.000), but there was no difference for sarcomatoid (9.3 months vs 3.2 months, p =0.16) or biphasic cell types (9.4 months vs 7 months, p =0.38). Conclusion: If a patient with epithelioid MPM is fit enough to tolerate a thoracotomy then macroscopic clearance of the tumour is the preferred option as part of a multimodality regime including chemotherapy.
