摘要: Angiogenesis is an essential step in the growth and spread of solid tumors-the cause more than 85% cancer mortality. Inhibiting angiogenesis would therefore seem to be a reasonable approach prevent or treat cancer. However, tumor differs from normal that resulting vessels are tortuous, irregularly shaped, hyperpermeable. These abnormalities result irregular blood flow high interstitial fluid pressure within tumor, which can impair delivery oxygen (a known radiation sensitizer) drugs tumor. Emerging evidence suggests antiangiogenic therapy prune some normalize structure function rest, thereby improving drug normalizing microenvironment. This normalization effect may underlie therapeutic benefit combined cytotoxic therapies. paper reviews current emerging concepts mechanism action therapies discusses implications these mechanisms for their optimal clinical use.
