Meta AnalysisEffectivity and safety of PD-1/PD-L1 inhibitors for different level of PD-L1-positive, advanced NSCLC: A meta-analysis of 4939 patients from randomized controlled trials.
Effective improvement for the programmed death 1 (PD-1)/programmed death ligand 1 (PD-L1) inhibitors had been shown in advanced non-small cell lung cancer (NSCLC) patients compared with traditional therapy. However, we do not have ample evidences to demonstrate the safety and effectivity in the treatment of PD-L1-positive, advanced NSCLC. The relation was controversial about the expression of PD-L1 and survival outcomes of PD-1/PD-L1 inhibitors. ⋯ PD-1/PD-L1 inhibitors are generally effected and safer than chemotherapy for patients with PD-L1-positive, advanced NSCLC. However, PD-1/PD-L1 inhibitors can generate a unique spectrum of irAEs, and even life-threatening.
