JCO:甲氨蝶呤与激素疗法对于高危B系急性淋巴细胞白血病患儿神经认知功能的影响

2017-07-19 xuyihan MedSci原创

儿童急性淋巴细胞白血病(ALL)的幸存者面临着与治疗、个体及环境因素相关的神经认知功能缺陷的危险。2017年7月JCO上发表的一篇文章研究了甲氨喋呤(MTX)和糖皮质激素治疗对于高危B系ALL患儿神经认知功能的不同影响。

儿童急性淋巴细胞白血病ALL)的幸存者面临着与治疗、个体及环境因素相关的神经认知功能缺陷的危险。20177JCO上发表的一篇文章研究了甲氨喋呤(MTX)和糖皮质激素治疗对于高危BALL患儿神经认知功能的不同影响。    

参与者被随机分配接受大剂量MTX和四氢叶酸钙或更高剂量的MTXPEG天冬酰胺酶而非四氢叶酸钙。患者也被随机分配至皮质类固醇治疗组,予以地塞米松或强的松。在治疗接受后8-24个月,进行智力功能(IQ)、工作记忆和加工处理速度(PS)一系列神经认知评估(n=192)。

在控制种族、民族、年龄、性别、保险状况和治疗时间这些变量后,MTX和皮质类固醇治疗在神经认知的结果上并没有差异。然而,与诊断时≥10岁的幸存者相比,<10岁(n=89)的幸存者有显著较低的IQp<0.001)和PS评分(p=0.02)。此外,享受美国公共医疗保险的患儿其IQ显著低于享受美国私人或军人保险的患儿(p<0.001)。

小于10岁就获得诊断的高风险BALL患儿在未进行颅脑放射的情况下,有IQPS缺失的风险。这些数据可以作为制定筛查方案的基础,从而确诊有高风险的患儿,以便及早干预减轻治疗对神经认知结果的影响。
