N2 - Antiangiogenic therapies that target VEGF or its receptors have become a mainstay of cancer therapy in multiple malignancies. However, the clinical efficacy of these agents is less than originally anticipated and, in most settings, requires the addition of cytotoxic chemotherapy suggesting that, as for other targeted therapies, VEGF inhibitors will require selection of patient subpopulations to achieve maximal clinical benefit. Without the identification and use of predictive biomarkers for VEGF-targeted agents, and other agents that target the vasculature, further improvements in current clinical outcomes are unlikely. Exciting new data presented in 2011 at the ESMO conference showed that retrospective evaluation of plasma concentrations of VEGF-A predicted progression-free survival and/or overall survival benefit from bevacizumab in phase III trials in certain tumour types; prospective evaluation of the assay is required. This endeavour should be followed by further biomarker research, requiring inter-laboratory collaboration and high-quality, adequately powered clinical trials.
