About

Chemotherapy drugs improve cancer survival but increase the risk of cardiovascular disease (CVD). VEGF inhibitors (VEGFI) cause severe hypertension, while cisplatin appears pro-thrombotic. Hence while cancer survival may improve, this is at the risk of potentially severe CVD and associated morbidity. Mechanisms underlying the cardiovascular toxicities of VEGFI and cisplatin are unknown, but effects on vascular function may be important.

The INTELLECT study will phenotype the endothelial effects of VEGFI and cisplatin using a variety of methods.

Full description

There remains an unmet need to identify a preventive treatment for patients with testicular cancer treated with platinum based chemotherapy to diminish the risk of subsequent cardiovascular events. A future randomised trial of statin therapy in these patients is under consideration and results from this study will inform its design.

The information gained from this pilot study will guide the development of interventional pharmacological studies that are directed towards the most appropriate pathophysiological processes, at the most appropriate time and in the most appropriate patient groups treated with platinum based chemotherapy for testicular cancer.
