Br J Haematol:阿扎胞苷,7号染色体异常的高风险MDS患者的福音?

2018-08-17 吴星 环球医学

2018年5月,西班牙和法国学者在《Br J Haematol》发表了GESMD和GFM注册的回顾性比较,表明阿扎胞苷(AZA)可改善7号染色体异常的高风险骨髓增生异常综合征(HR-MDS)患者的结局。

2018年5月,西班牙和法国学者在《Br J Haematol》发表了GESMD和GFM注册的回顾性比较,表明阿扎胞苷(AZA)可改善7号染色体异常的高风险骨髓增生异常综合征(HR-MDS)患者的结局。

背景:已经表明,AZA治疗对7号染色体异常(Abn 7)的HR-MDS患者具有获益。

方法和结果:这项回顾性研究纳入了235名Abn 7的HR-MDS患者,这些患者接受AZA(n=115)或最佳支持治疗(BSC;n=120)。研究评估了AZA治疗作为多变量分析的时变变量。具有不同时间点时的总生存率(OS)时间交互项的Cox回归模型证实,虽然随着时间的推移,7号染色体的细胞遗传学分类(复杂核型[CK]vs非CK)和国际预后积分系统风险(高vs中级-2)仍然具有较差预后,但与BSC相比,治疗前3年期间,AZA治疗对OS具有有利的影响(第一年:风险比[HR],0.5,P<0.001;第二年:0.7,P=0.019;第三年:0.73,P=0.029)。AZA也显著改善无进展生存期(P<0.01)。全部染色体7个分类中均出现此获益,但CK患者的获益更大(CK患者:1、3和6个月时风险降低82%、68%和53%;非CK患者1个月时风险降低79%,全部P<0.05)。

结论:研究证实,AZA对细胞遗传学异常(包括7号染色体)的HR-MDS患者的结局具有时间依赖的获益。
