Aim: This study was conducted to evaluate the efficacy of immune checkpoint inhibitors (ICIs) plus anlotinib versus anlotinib alone to provide guidance for clinical treatment of non-small-cell lung cancer. Patients & methods: The records of 139 patients with advanced non-small-cell lung cancer who received at least one dose of ICIs plus anlotinib (IA group) or single-agent anlotinib (AA group) were retrospectively reviewed. The efficacy of the treatments, survival outcomes and adverse events were analyzed. The primary end point was investigator-assessed progression-free survival (PFS). Result: The IA group had a significantly prolonged median PFS (mPFS: 5.8 vs 4.2 months; p = 0.022) compared with the AA group (hazard ratio: 0.68; 95% CI: 0.68-0.97). In patients with brain metastases, the IA group exhibited improved efficacy (mPFS: 6.0 vs 3.8 months; p = 0.034) compared with the AA group (hazard ratio: 0.49; 95% CI: 0.23-1.05). Conclusion: ICIs plus anlotinib significantly improved efficacy compared with anlotinib alone and showed substantial potential for the control of intracranial lesions.
