Purpose: Anlotinib is a novel tyrosine kinase inhibitor with promising anti-tumor activity in patients with advanced soft tissue sarcomas (STS) in China. Liposomal doxorubicin monotherapy showed an encouraging effect on this disease. The aim of this study was to evaluate the efficacy and safety of anlotinib combined with liposomal doxorubicin followed by anlotinib maintenance in patients with metastatic STS.
Patients and Methods: This is a multicenter, retrospective, observational study. We reviewed 27 patients with metastatic STS from July 2018 to December 2019, who were treated with anlotinib combined with liposomal doxorubicin followed by anlotinib maintenance in the absence of the tumor progression or intolerable adverse events (AEs).
Results: Of the 27 patients included, 2 patients had complete response (CR), 9 patients obtained partial response (PR), 11 patients achieved stable disease (SD). The objective response rate was 40.7%, the disease control rate was 81.5%, and the median progression-free survival (PFS) was 7 months (95% CI, 5.3– 8.1 months). The progression-free rate (PFR) at 3 and 6 months was 81.5% and 59.3%, respectively. Most AEs were mild and acceptable. The most frequent grade 3/4 AEs were leukopenia (33.3%), febrile neutropenia (7.4%), and anemia (7.4%). No deaths related to the treatment were reported.
Conclusion: This study shows that anlotinib combined with liposomal doxorubicin followed by anlotinib maintenance is effective in patients with metastatic STS, and most AEs of this combined therapy are mild and acceptable. Further investigation on its efficacy is warranted.
