Objective
We reviewed the available literature on patients with MPM undergoing either extrapleural pneumonectomy (EPP) or pleurectomy/decortication (P/D).
Methods
Original research studies that evaluated long-term outcomes of P/D versus EPP were identified, from January 1980 to February 2022. The 30-days and 90-day mortality, along with the 1-, 2-, 3-, 5-year survival, the median overall survival, the macroscopic complete resection (MCR) rate, and the complications were calculated according to both a fixed and a random effect model. The Q and I2 statistic were used to test for heterogeneity among the studies. Sensitivity analysis was performed including only studies that incorporated the MCR concept.
Results
Eighteen studies were included, incorporating a total of 4,852 patients treated with EPP and P/D. The 30-day mortality was significantly higher in the EPP group (OR: 2.79 [95% CI 1.30, 6.01]; p = 0.009). The median overall survival was higher in the P/D group (WMD:-4.55 [-6.05, -3.04]; p < 0.001). No differences were found regarding the 90-day mortality, MCR rate, and the 1-, 2-,3-, 5-year survival between the EPP and P/D groups. These findings were validated by the sensitivity analysis. The incidence of atrial fibrillation, hemorrhage, pulmonary embolism, air leak, and reoperation was significantly increased in the EPP group (p < 0.05).
Conclusions
The present meta-analysis indicates that P/D is associated with enhanced outcomes regarding 30-day mortality, median overall survival, and complications. The P/D approach should be preferred when technically feasible. However, the procedure of choice should be decided based on the goal of MCR in the safest approach for the patient.
