Abstract
Introduction:
In inoperable pleural mesothelioma, pemetrexed + cisplatin as first line is considered the standard of care, but novel treatments have been recently proposed. Our objective was to comparatively examine the information on overall survival (OS) with these new agents.
Methods
The Shiny technique was employed for reconstructing individual patient data. Cox statistics was run to estimate hazard ratios (HRs). After a standard literature search, four new treatments were identified (nivolumab + ipilimumab, bevacizumab + pemetrexed + cisplatin, pembrolizumab monotherapy, and durvalumab + pemetrexed + cisplatin). Pemetrexed + ciplatin was the treatment for controls.
Results
Nivolumab + ipilimumab and bevacizumab + pemetrexed + cisplatin showed a better OS compared with controls (HR, 0.79 and 0.79, respectively; p < 0.05). Pembrolizumab determined only a numerical improvement (p > 0.05). In contrast, OS worsened with durvalumab + pemetrexed + cisplatin.
Discussion
Our analysis indicates that the novel treatments for inoperable mesothelioma have similar efficacy and, in general, provide a small though significant survival benefit compared with standard of care. Further research is needed to identify agents determining a more substantial OS improvement.
