Anti-angiogenic drugs, vascular toxicity and thromboembolism in solid cancer.

Anti-angiogenic drugs, vascular toxicity and thromboembolism in solid cancer. Cardiovasc Hematol Agents Med Chem. 2017 Jan 26; Authors: Riondino S, Monte GD, Fratangeli F, Guadagni F, Roselli M, Ferroni P Abstract Neo-angiogenesis, a key step in cancer progression, is a highly regulated process, in which vascular endothelial growth factor (VEGF) plays a fundamental role, thus representing the most suitable anti-angiogenic target. In the last years, a number of anti-VEGF drugs have been developed and approved for therapeutic use, especially in combination with standard chemotherapy. VEGF, however, is not only crucial for physiological and pathological angiogenesis, but also for maintenance of vascular homeostasis, at a point that its pharmacological blockade may lead to endothelial dysfunction and adverse vascular effects, such as venous thromboembolism. The picture is further complicated by the understanding that the amount of VEGF production is influenced by genetic factors, with environmental ones accounting only for 20-30% of its variations. This has recently prompted the design of various pharmacogenetic studies to investigate the role of VEGF polymorphisms in determining the pharmacological response and safety profile of various anti-angiogenic drugs, suggesting that the analysis of VEGF genetic variants in cancer patients may further help in personalize anti-angiogenic pharmacological strategies. In this review we will initiall...
