CLIN CANCER RES:评价免疫治疗临床研究的新方法

2018-05-30 MedSci MedSci原创

在评估免疫治疗药物的临床试验中,通过RECIST评价标准定义的客观反应率(ORR)以及无进展生存与总生存之间关系较弱。CLIN CANCER RES近期发表了一篇文章,报道了新的中间反应终点(IME)用于评估免疫治疗的效果。

在评估免疫治疗药物的临床试验中,通过RECIST评价标准定义的客观反应率(ORR)以及无进展生存与总生存之间关系较弱。CLIN CANCER RES近期发表了一篇文章,报道了新的中间反应终点(IME)用于评估免疫治疗的效果。

作者将IME反应定义为无非目标区域进展,无新病变区域出现以及达到根据基线肿瘤负荷,肿瘤退化程度和随机一年后肿瘤改变情况定义的目标区域反应。纳入的数据来自免疫治疗的随机临床试验。IME的标准通过训练数据集建立,并通过独立的验证数据集进行评估。将两部分数据综合分析比较有IME反应和无IME反应患者之间的总生存的差别。使用线性回归模型分析总生存风险比和IME比值比。研究最终纳入9个临床试验的5806例患者。在患者水平,有IME反应的患者与无反应患者相比总生存改善。在临床试验水平,总生存和IME之间中度相关。

文章最后认为,IME与总生存中度相关,相关性强于RECIST定义的ORR与OS之间的相关性。但是,该研究为探索性研究,需要在将来的研究中进一步进行评估。
