Neovascularization is intimately involved in tumor survival, progression, and spread, factors known to contribute significantly to treatment failures. Thus, strategies targeting the tumor blood vessel support network may offer not only unique therapeutic opportunities in their own right, but also novel means of enhancing the efficacies of conventional anticancer treatments. This article reviews one such therapeutic approach directed at the tumor blood vessel support network. Vascular disrupting therapies seek the destruction of the established neovasculature of actively growing tumors. The goal of these therapies is to cause a rapid and catastrophic shutdown in the vascular function of the tumor in order to arrest the blood flow and produce tumor cell death as a result of oxygen and nutrient deprivation and the build up of waste products.
新生血管形成与肿瘤的存活、进展和扩散密切相关,而这些因素是导致治疗失败的重要原因。因此,针对肿瘤血管支持网络的策略不仅本身可能提供独特的治疗机会,还可能成为增强传统抗癌治疗效果的新方法。本文综述了一种针对肿瘤血管支持网络的治疗方法。血管破坏疗法旨在破坏活跃生长肿瘤中已形成的新生血管。这些疗法的目标是使肿瘤的血管功能迅速发生灾难性的关闭,从而阻止血流,并由于氧气和营养物质的缺乏以及废物的积累导致肿瘤细胞死亡。
