Anlotinib has demonstrated durable clinical benefits in patients with unresectable or metastatic bone and soft-tissue sarcomas.
92 patients treated with chemotherapy combined with or without anlotinib were collected and analyzed. The objective response rate (ORR) and disease control rate (DCR) were analyzed. Long-term survival was assessed using the Kaplan-Meier method, including median progression-free survival (mPFS) and overall survival (mOS).
Liposarcoma, synovial sarcoma, and rhabdomyosarcoma were the primary pathological subtypes of the 92 patients. The median age was 46 (range, 11–75) years. The ORR and DCR of the anlotinib-chemotherapy combination used as first-line therapy were 31.9% and 85.1%, respectively. However, the ORR and DCR were only 6.7% and 57.8% in the chemotherapy alone, respectively. Compared with the chemotherapy group, improvements were observed in the mPFS and mOS with anlotinib-based regimen (mPFS, 8.3 vs. 3.0 months; mOS, 59.0 vs. 22.0 months). Anlotinib-associated adverse events were well tolerated and mainly occurred in grades I and II. New anlotinib-related adverse reactions were not noted.
Anlotinib-based regimen as a first-line therapy showed a positive effect on the treatment of unresectable or metastatic BSTSs. The anlotinib-associated adverse events were minor and well tolerated.
