【摘要】 新生血管生成是绝大多数肿瘤得以生长和转移的必要前提。所以 ,通过抑制肿瘤血管生成来抑制肿瘤是非常有前途的一种方法 ,有望发展成为一种新型的癌症疗法。主要可以分为两大类 :一是通过抑制促血管生成信号或扩大抑制血管生成因子的作用来干扰肿瘤新生血管的形成过程 ,这领域的广泛研究已经发现了一系列促血管生成因子及其抑制剂和血管生成抑制因子 ;二是利用肿瘤血管与正常血管的差别来携带杀伤性药物直接特异性破坏已形成的肿瘤血管 ;另外 ,内皮细胞及其前体细胞制成疫苗也可起到直接杀伤作用。到目前为止 ,虽然很多抑制肿瘤血管的药物已经被用于临床试验 ,但结果往往不尽如人意 ,从长远来看 ,需要更有效的治疗方法。包括抗血管基因治疗策略 ,靶向药物导入系统的研究 ,以及抗血管生成药物和免疫疗法、化疗和放射治疗的联合应用都在探讨中。随着肿瘤模型评估系统的发展 ,抗血管治疗肿瘤的方法在不久的将来一定会广泛进入临床应用。更多还原

【Abstract】 Neovascularization is a prerequisite for progressive growth of most tumors and their metastases. Therefore, inhibition of angiogenesis could be one of the most promising strategies that might lead to the development of novel anticancer therapy. New blood vessels forming in tumors can be avoided by interfering the process of angiogenesis through suppressing the proangiogenic signal or augmenting the antiangiogenic factors. Concentrated efforts in this area have lead to the discovery of many proangiogenic factors as well as their inhibitors, and antiangiogenic factors. For the established tumor vasculature, tumor vasculature-targeted delivery of antiangiogenic substances and endothelial cell vaccines has been explored. Although some antiangiogenic drugs are currently in clinical development, for future reason, more efficient therapeutic methods, including antiangiogenic gene therapy strategy, targeted drug delivery system, and the combination of antiangiogenic agents with immunotherapy, chemotherapy or radiotherapy are being explored. With the development of tumor model assessment system, clinical use of the above antiangiogenic tumor therapy methods could be achieved.更多还原
