抗VEGF及其受体分子靶向药物治疗肝癌机制的研究进展

Advances of VEGF signalling pathway in hepatocellular carcinomar invasion and metastasis and therapy

肝细胞癌(hepatocellular carcinoma,HCC)的发生发展过程与肿瘤血管的形成密切相关。由血管内皮生长因子(VEGF)介导的血管生成是肿瘤产生免疫逃逸反应的主要驱动因素,VEGF与内皮细胞上血管内皮生长因子受体(vascularendothe-lial growth factor receptor2,VEGFR2)结合后,促进内皮细胞增殖和迁移,诱导肝癌发生血管改变,进而促进肝癌细胞生长。抗VEGF及其受体分子靶向药物是目前治疗肝癌的有效新手段。针对VEGF的单克隆抗体和靶向VEGF的小分子酪氨酸激酶抑制剂已显示出阻断其血管生成活性,缓解肿瘤微环境的抑制作用,最终达到消退肿瘤的作用。本文就VEGF/VEGFR抑制剂在肝癌治疗中的研究进展作一综述。

The development of hepatocellular car-cinoma(HCC)is closely related to the formation of tumour blood vessels.VEGF-mediated angiogenesis is a major driver of the immune escape response in tumours.VEGF binds to vascular endothelial growth factor receptor2(VEGFR2)on endothelial cells,promoting endothelial cell proliferation and migration,inducing vascular changes in HCC,and thus promote the growth of hepatocellular carcino-ma cells.Anti-VEGF and its receptor-targeted mo-lecular drugs are currently effective new treat-ments for HCC.Monoclonal antibodies against VEGF and small-molecule tyrosine kinase inhibitors targeting VEGF have been shown to block its angio-genic activity,alleviate the inhibitory effect of the tumour microenvironment,and ultimately achieve tumour regression.This article provides a review of the research progress of VEGF/VEGFR inhibitors in HCC treatment.
