Hypertension is a toxicity of antiangiogenic therapies and a possible biomarker that identifies patients with superior cancer outcomes. Understanding its mechanism will aid in treatment and could lead to the development of other biomarkers for predicting toxicity and anticancer efficacy. Recent evidence implicates nitric oxide (NO) suppression and endothelin-1 (ET-1) stimulation as potential mechanisms leading to antiangiogenic therapy-induced hypertension. The aim of this study was to evaluate the effects of regorafenib, a novel broad-spectrum kinase inhibitor with activity against multiple targets, including vascular endothelial growth factor receptor 2 inhibition, on NO and ET-1 levels.
