Prognostic Role of Programmed Cell Death 1 Ligand 1 in Resectable Pleural Mesothelioma

The prognostic role of programmed cell death 1 ligand 1 (PD-L1) in malignant pleural mesothelioma (MPM) is incompletely understood. Our objectives were to evaluate the evidence for tumor PD-L1 as a prognostic biomarker in MPM through meta-analysis and to determine whether tumor PD-L1 expression is associated with survival in MPM patients undergoing macroscopic complete resection.Meta-analysis was performed to determine the association of PD-L1...
