CLIN CANCER RES:Ipilimumab联合放疗与机体免疫的相关性

2017-03-25 xingxiaowei MedSci原创

免疫治疗与放疗结合对于机体免疫功能的影响及其临床效果一直缺乏有效地数据支持。近期发表在CLIN CANCER RES上的一篇文章针对这一课题进行了研究。

免疫治疗与放疗结合对于机体免疫功能的影响及其临床效果一直缺乏有效地数据支持。近期发表在CLIN CANCER RES上的一篇文章针对这一课题进行了研究。

患者在接受Ipilimumab治疗(每3周3mg/kg,4次)时,同时(第1次给药)或序贯(第2次给药后1周)接受立体定向放射治疗(SABR),治疗共分为5组:Ipilimumab治疗同时联合50Gy肝脏放疗,Ipilimumab治疗序贯50Gy肝脏放疗,Ipilimumab治疗同时联合50Gy肺脏放疗,Ipilimumab治疗序贯50Gy肺脏放射治疗,肝脏或肺脏序贯60Gy放疗。使用流式细胞仪检测免疫分子的表达。

在接受Ipilimumab治疗的35名患者中,两名出现剂量依赖毒性,12名出现3级毒性。在31名患者中观察到放射区域外反应。3人出现部分部分缓解,7人有临床获益(临床获益定义为部分缓解或病情稳定持续时间>6个月)。临床获益与外周CD8+T细胞、CD8+/CD4+比例,以及表达4-1BB和PD1的CD8+T细胞比例增高有关。肝脏照射相比与肺脏照射对于T细胞活化作用更强,表达ICOS、GITR以及4-1BB的外周T细胞比例增加。

Ipilimumab联合SABR安全有效,外周T细胞标志可以用来预测临床获益,肝脏照射后机体免疫功能更强。
