BACKGROUND: Antiangiogenic treatments play an important role in the therapeutic strategy for metastatic renal cell carcinoma. Apatinib is an oral tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor-2. We aimed to assess the efficacy and safety of apatinib therapy in metastatic renal cell carcinoma patients.
METHODS: Between January 2018 and November 2018, we enrolled 53 metastatic renal cell carcinoma patients. Apatinib was administered at an initial dose of 500 mg once daily. The disease control rate, objective response rate, progression-free survival, and adverse events were reviewed and evaluated.
FINDINGS: Among the 53 patients, 14 achieved partial response and 31 achieved stable disease. Thus, the disease control rate was 84.9% and the objective response rate was 26.4%. The median progression-free survival was 11.2 months (95% confidence interval: 9.884-12.574). Most of the adverse events (AEs) were at grade 1 or 2, and the main grade 3 AEs were hypertension (5.7%), anemia (3.8%), and thrombocytopenia (3.8%).
INTERPRETATION: Apatinib showed promising efficacy and manageable toxicity in metastatic renal cell carcinoma patients, giving potent evidence to conduct further clinical trials.
