Abstract

We performed a systematic review and comparative meta-analysis of cardiovascular toxicities associated with sunitinib, axitinib, cediranib or regorafenib; oral multi tyrosine kinase inhibitors.Eligible studies included randomized phase II and III trials of patients with solid tumors on sunitinib, axitinib, cediranib or regorafenib describing daily events of hypertension, left ventricular dysfunction, bleeding or thrombosis.Patients treated with these four agents had a significantly increased risk of all-grade hypertension and bleeding. The RR of all-grade hypertension, bleeding, thrombosis and cardiac dysfunction were 2.78 (95% CI 2.03-3.81; p<0.00001), 1.93 (95% CI 1.41-2.64; p<0.00001), 0.85 (95% CI 0.60-1.19; p=0.50), 2.36 (95% CI 0.95-5.87; p=0.06), respectively. Exploratory subgroup analysis showed no effect of the agent used (sunitinib vs. axitinib vs. cediranib) in the risk of hypertension; while for bleeding, only the sunitinib subgroup RR was significant compared to axitinib or cediranib.Our meta-analysis has demonstrated that sunitinib, axitinib, cediranib and regorafenib are associated with a higher risk of developing all grade and high grade hypertension compared with control. While for bleeding, only the sunitinib subgroup RR was significant compared to axitinib or cediranib. Clinicians should be aware of these risks and perform regular cardiovascular monitoring.Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.
