The patients were divided into two treatment groups: anlotinib (12mg) plus S-1 (25mg) combination group and anlotinib (12mg) monotherapy group. The efficacy and adverse reactions of the two groups were compared.Results: In terms of the short-term efficacy, there were no significant differences in objective response rate (ORR) (20.0% vs 10.0%, p = 0.464) and disease control rate (DCR) (75.0% vs 60.0%, p = 0.181) between the two groups. As for the long-term efficacy, there was no significant difference in progression-free survival (PFS) between the two groups (3.87± 0.29 months vs 3.00± 0.24 months, p=0. 11). The overall survival (OS) of patients in the combination group was longer than S1 group (8.07± 0.56 months vs 6.17± 0.42 months, p=0.022).Conclusion: Advanced SqCLC patients with higher PS scores still benefit from anlotinib and S-1 combination regimen, even after they failed second-line or later-line systemic treatment.Keywords: anlotinib, S-1, advanced squamous cell lung cancer, performance status, efficacy
