Angiogenesis or new vessel formation is essential for tumour growth and progression. Therefore, targeting angiogenesis has been an attractive strategy in the treatment ofcancer. Bevacizumab is a recombinant humanized monoclonal IgG1 antibody thattargets vascular endothelial growth factor-A (VEGF-A) - a key molecular player inangiogenesis. Bevacizumumab has shown clinical efficacy in phase III clinical trials inseveral advanced solid malignancies. The clinical efficacy of bevacizumumab isprimarily due to its antiangiogenic effects; however, there are direct antitumor effectsand immunomodulatory effects. Enhancing the immune system to restore itsantitumour activity has been utilized successfully in clinical setting. In this article we willdiscuss the possible immunomodulatory effects of the most clinically usedantiangiogenic agent; bevacizumumab.
血管生成或新血管形成对于肿瘤的生长和进展至关重要。因此,靶向血管生成一直是癌症治疗中一种有吸引力的策略。贝伐单抗是一种重组人源化单克隆IgG1抗体,其靶向血管内皮生长因子-A(VEGF-A)——血管生成中的关键分子。贝伐单抗在多种晚期实体恶性肿瘤的III期临床试验中已显示出临床疗效。贝伐单抗的临床疗效主要归因于其抗血管生成作用;然而,它也有直接的抗肿瘤作用和免疫调节作用。增强免疫系统以恢复其抗肿瘤活性已在临床环境中成功应用。在本文中,我们将讨论临床上最常用的抗血管生成药物贝伐单抗可能的免疫调节作用。
