| Summary: | Objective: Immune checkpoint inhibitors (ICIs) have recently demonstrated promising results in improving the prognosis of cancer patients. The goal of this meta-analysis was to determine the impact of probiotic use on the survival of cancer patients treated with ICIs.Methods: Before 3 March 2022, the eligible literature was searched using PubMed, EMBASE, Cochrane Library, Google Scholar, and Clinical trials.gov databases. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR) were the primary endpoints.Results: A total of 6 studies met the inclusion criteria, and 1,123 patients were included. Meta-analysis showed a trend for probiotic use to prolong PFS (HR: 0.585, 95% CI: 0.328-1.045, p = 0.070) and increase DCR (HR: 1.868, 95% CI: 0.890-3.922, p = 0.099), although it was of borderline statistical significance. We also found that probiotics significantly improved OS (HR: 0.526, 95% CI: 0.341-0.812, p = 0.004) and ORR (OR: 2.831, 95% CI: 1.578-5.076, p < 0.001) in ICI-treated cancer patients. Besides, subgroup analysis showed that non-small cell lung cancer (NSCLC) patients treated with ICIs in combination with probiotics would achieve significantly longer PFS (HR: 0.532, 95% CI: 0.354-0.798, p = 0.002) and OS (HR: 0.528, 95% CI: 0.306-0.912, p = 0.022), as well as higher ORR (OR: 2.552, 95% CI: 1.279-5.091, p = 0.008) and DCR (OR: 2.439, 95% CI: 1.534-3.878, p < 0.001). Sensitivity analysis showed that the above results are stable and reliable. The publication bias test confirmed that there was no publication bias in these results.Conclusion: Current evidence reveals that probiotics can improve the efficacy of ICI treatment in NSCLC patients.Systematic Review Registeration:https://www.crd.york.ac.uk/prospero/, identifier CRD42022316104. |
