    BackgroundTaxane chemotherapy represents the standard of care in the second-line setting for non-small cell lung cancer (NSCLC) patients, but immunotherapy agents pose great challenges. Whether immunotherapy/chemotherapy alone or combination therapy has more benefits remains controversial. In this study, we provided comparisons to integrate the efficacy of immunotherapy and taxane chemotherapy as second- or later-line treatments in advanced NSCLC.MethodsPubMed, Web of Science, Embase, and Cochrane Central Register of Controlled Trials were systematically searched from inception to September 1, 2020. Randomized controlled trials comparing immunotherapy and taxane chemotherapy were enrolled in the Bayesian network analysis. Overall survival (OS) and progression-free survival (PFS) with hazard ratios (HRs) were investigated.ResultsEight trials in 13 studies with 4398 patients comparing seven treatments were identified. Pembrolizumab 10 mg/kg was associated with the best improved OS, with significant differences versus docetaxel (HR 0.81, 95% credible interval [CrI] 0.74-0.88), avelumab (HR 0.84, 95% CrI 0.75-0.95), and pembrolizumab 200 mg plus docetaxel (HR 0.75, 95% CrI 0.56-1.00). Although pembrolizumab 200 mg plus docetaxel ranked the last in terms of OS, the combination therapy showed the most favorable PFS. Additionally, the anti-programmed death-ligand 1 (PD-L1) agent, avelumab, was associated with the least improvement in PFS.ConclusionAs second- or later-line therapeutic strategies, pembrolizumab 10 mg/kg provided the largest OS benefits and pembrolizumab 200 mg plus docetaxel improved PFS to the greatest extent. Considering that immunotherapy has been recommended to the first-line setting of NSCLC, advanced patients who have not received immunotherapy previously might be the suitable population for our findings.Copyright © 2022 the Author(s).
