      Background
      Malignant pleural mesothelioma (MPM) is an aggressive disease of the pleural lining with a dismal prognosis of 6 – 12 months from the time of diagnosis. Surgical treatment of MPM includes extrapleural pneumonectomy and pleurectomy/decortication (P/D). Recently, IASLC has reclassified P/D according to therapeutic intent and surgical technique into partial P/D, P/D, and radical P/D. The present meta-analysis aimed to compare the perioperative and long-term outcomes of EPP and radical P/D for patients with resectable MPM.

      Methods
      A systematic review of the literature was performed on five electronic databases to identify all relevant data on comparative outcomes of radical P/D and EPP. Endpoints included perioperative mortality and overall morbidity, as well as long-term overall survival.

      Results
      Six relevant studies with comparative data of EPP (n= 601) versus radical P/D (n=493) were identified from the current literature. Comparison of these two groups demonstrated significantly lower perioperative mortality (3.0% vs 6.5%, p=0.04) and overall morbidity (30.4% vs 64.3%, p<0.0001) for patients who underwent radical P/D compared to EPP. Median overall survival ranged between 13 – 29 months for radical P/D and 12 – 22 months for EPP, with a strong trend favouring radical P/D. Figure 1Figure 2

      Conclusion
      Although it must be emphasized that patient selection and treatment strategies differ between EPP and radical P/D, a number of comparative studies have recently been conducted to compare these two surgical techniques for patients with resectable MPM. The present study indicated that appropriately selected patients who underwent radical P/D had lower perioperative morbidity and mortality with similar, if not superior, long-term survival compared to EPP.

      P2.07-032 - Video-Assisted Thoracic Surgery versus Open Thoracotomy for Non-Small Cell Lung Cancer - A Meta-analysis of Propensity Score Matched Patients (ID 2816)

      09:30 - 09:30  |  Author(s): S. Peeceeyen

      • Abstract

      Background
      This meta-analysis aims to compare the perioperative outcomes of video-assisted thoracic surgery (VATS) versus open thoracotomy for propensity score-matched patients with early-stage non-small cell lung cancer (NSCLC).

      Methods
      Four relevant studies with propensity score-matched patients were identified from six electronic databases. Endpoints included perioperative mortality and morbidity, individual postoperative complications and duration of hospitalization.

      Results
      Results indicate that all-cause perioperative mortality was similar between VATS and open thoracotomy. However, patients who underwent VATS were found to have significantly fewer overall complications, and significantly lower rates of prolonged air leak, pneumonia, atrial arrhythmias and renal failure. In addition, patients who underwent VATS had a significantly shorter length of hospitalization compared to patients who underwent open thoracotomy. Figure 1 Figure 2

      Conclusion
      In view of a paucity of high level clinical evidence in the form of large, well-designed randomized controlled trials, propensity score matching may provide the highest level of evidence to compare VATS with open thoracotomy for patients with NSCLC. The present meta-analysis demonstrated superior perioperative outcomes for patients who underwent VATS, including overall complication rates and duration of hospitalization.
