肺癌是全球男性常见癌症,大部分肺癌患者在确诊时已属晚期。对于肺癌晚期患者来说,放疗、化疗的不良反应较大,患者无法耐受;靶向药物普遍存在耐药现象;免疫治疗受程序性死亡配体-1(programmed cell death protein 1,PD-L1)的表达限制;...肺癌是全球男性常见癌症,大部分肺癌患者在确诊时已属晚期。对于肺癌晚期患者来说,放疗、化疗的不良反应较大,患者无法耐受;靶向药物普遍存在耐药现象;免疫治疗受程序性死亡配体-1(programmed cell death protein 1,PD-L1)的表达限制;抗血管治疗的出现为晚期肺癌患者提供了更多的选择。目前,多种药物联合治疗肺癌的手段日渐成熟,抗血管药物联合化疗药物或靶向药物都取得了显著的疗效。在肺癌肿瘤生长过程中,环氧化酶-2(cyclooxygenase-2,COX-2)和血管内皮生长因子(vascular endothelial growth factor,VEGF)相互促进使肿瘤血管新生,所以,选择性COX-2抑制剂联合抗血管药物是否具有协同抗肿瘤作用,其抗肿瘤机制如何,本文将针对以上问题展开论述。展开更多
