JAMA ONCOL:脑脊液生物学标志与ALL儿童化疗后神经认知和大脑影像之间的关系

2018-03-30 MedSci MedSci原创

目前,关于急性淋巴细胞性白血病(ALL)儿童接受化疗的治疗相关神经毒性的研究很少。JAMA ONCOL近期发表了一篇文章,研究ALL诊断和治疗过程中脑脊液脑损伤生物学标志物的浓度,以评估其与长期神经认知和神经影像学结果及相关基因多态性之间的关系。

目前,关于急性淋巴细胞性白血病(ALL)儿童接受化疗的治疗相关神经毒性的研究很少。JAMA ONCOL近期发表了一篇文章,研究ALL诊断和治疗过程中脑脊液脑损伤生物学标志物的浓度,以评估其与长期神经认知和神经影像学结果及相关基因多态性之间的关系。

该前瞻性研究纳入235了ALL患者,患者仅接受化疗治疗。诊断后及治疗过程期间收集患者脑脊液标本。诊断5年后,198例生存患者中有138例参与了长期的随访评估。患儿在2001年6月1日至2010年10月31日之间接受治疗。2014年10月21日完成随访,2015年8月1日至2016年9月30日期间进行数据分析。研究分析的脑脊液标志物有髓鞘碱性蛋白(MBP),神经生长因子(NGF),总tau蛋白和磷酸化tau蛋白,胶质纤维酸性蛋白(GFAP)和壳三糖酶。分析了药物代谢,氧化应激和神经发育DNA亚型多态性。利用大脑影像学检查评估白质脑病。诊断5年后,生存患者完成神经认知测验及白质完整性影像学检查。研究结果表明,235例患者的脑脊液标本中,基线及治疗过程中MBP和GFAP水平升高。鞘内注射次数与NGF水平升高正相关。GFAP,MBP和总tau蛋白水平升高与诊断5年后白质脑病风险增加和额叶白质ADC值增加有关。

文章最后认为,ALL诊断时便可能存在胶质损伤。神经元损伤与鞘内化疗有关。脑脊液的生物学标志在鉴别神经功能预后不良的患者中具有一定作用。
