尽管在过去20年里,一直尝试提高ambiguous白血病(ALAL)的定义,但还是缺乏常规治疗指南。Blood杂志上近日发表一篇文章,研究人员报告了大批的ALAL患儿,并提出治疗策略。

IBFM-AMBI2012研究是一回顾性的国际性研究,共囊括233例ALAL患儿。采用生存率统计比之间亚组和治疗类型之间的预后。急性淋巴细胞白血病(ALL)-型初始治疗的患儿的五年无事件存活率(5yEFS)优于采用急性粒细胞白血病(AML)-型或联合型治疗的患儿的5yEFS(80±4% vs 36±7.2%、50±12%)。

如果排除ALL或AML特异性融合基因,CD19pos白血病,采用ALL型初始治疗的5yEFS是83±5.3%,而用AML型和联合型治疗的5yEFS仅0±0%和28±14%。ALL型治疗的优越性在单人种混合表型ALAL(根据WHO和/或EGIL定义)和双线ALAL中均得到证实。

推荐大部分ALAL患儿采用ALL型治疗方案,包括CD19pos ALAL患儿。对于少数携带CD19neg的ALAL病例和无其他淋巴瘤特征的ALALs,首选AML型疗法。移植的效果尚无文献记录,可推荐用于对现有治疗反应不佳的患者。本研究结果为前瞻性临床试验提供基本理论。
