Anticancer drugs under pressure

Angiogenesis inhibitor drugs, targeting VEGF (vascular endothelial growth factor) are used increasingly in oncology for a wide range of advanced cancers (colorectal cancer, lung cancer, renal cell cancer,...). Generally, they are well tolerated but cardiovascular and renal side effects may appear. The most frequent complications are hypertension and proteinuria which, very often, remain asymptomatic. Therefore, they have to be searched for systematically before and during the treatment. Sometimes, anti-hypertensive medication is needed. We are just beginning to understand the pathophysiological mechanisms of antiangiogenic therapies. Only a multidisciplinary approach will improve our knowledge of those target agents and allow a better management of the cancer patient.
