Cox multivariate analysis showed a high risk of death for non-operated patients [hazard ratio (HR), 3.42 (1.15–10.16)] with low tumor mesothelin levels [HR, 2.58 (1.09–6.10)] and high PD-L1 and low infiltration of T cells CD4+ [HR, 3.81 (1.58–9.18)]. This evidence concerns the gene CD274 and neoplasm.
