EUR J Cancer:基于随机试验的meta分析:贝伐单抗在实体瘤中的作用

2017-12-30 MedSci MedSci原创

贝伐单抗是一种人源化的单克隆抗体,能够抑制循环血管内皮生长因子与其受体的结合。 迄今为止,美国FDA已经批准贝伐单抗用于治疗多种实体瘤。为了评估以贝伐单抗为基础的治疗方案对这些晚期实体瘤患者的影响,研究人员进行了一项meta分析,研究人员对所有的随机试验(II期或III期)中贝伐单抗、安慰剂和其他抗肿瘤药物进行了对比。

贝伐单抗是一种人源化的单克隆抗体,能够抑制循环血管内皮生长因子与其受体的结合。 迄今为止,美国FDA已经批准贝伐单抗用于治疗多种实体瘤。为了评估以贝伐单抗为基础的治疗方案对这些晚期实体瘤患者的影响,研究人员进行了一项meta分析,研究人员对所有的随机试验(II期或III期)中贝伐单抗、安慰剂和其他抗肿瘤药物进行了对比。

该项以随机对照试验(RCTs)为基础的文献meta分析的主要终点是总生存(OS),次要终点是无进展生存(PFS)时间,有效率和安全性。在结直肠癌肺癌卵巢癌和肾癌治疗中,基于贝伐单抗治疗方案显示出了显著提高的总生存期(HR 0.9295%置信区间[CI]0.88-0.95P <0.0001),PFSHR 0.7295% CI0.67-0.78P <0.00001)和客观反应率(HR 1.3895% CI1.27-1.50P <0.00001)。 但值得注意的是,在乳腺癌中没有观察到对总生存的影响。

因此,这项研究证实了以贝伐单抗为基础的方案对晚期结直肠癌,肺癌,卵巢癌和肾癌的生存期和客观反映率具有显著效果。
