Biology of anti-angiogenic therapy-induced thrombotic microangiopathy.

Anti-vascular endothelial growth factor (VEGF) agents are an important component in the treatment of many solid tumors. As the indications for these targeted therapies grow, the expected number of patients to receive these drugs will increase exponentially. Despite the great promise, serious toxicities may arise. Here, we discuss the incidence, pathogenesis, and management of proteinuria and renal insufficiency associated with this class of drugs.
