Blood:基因突变结合基因表达水平分析可提高APL患者预后的预测

2019-07-14 MedSci MedSci原创

Lucena-Araujo等人将突变分析和与急性早幼粒细胞白血病(APL)和急性髓系白血病预后不良相关基因的异常表达情况结合起来,提出一种APL综合得分 (ISAPL),并证实其与采用全反式维甲酸(ATRA)联合蒽环类药物化疗的患者的临床预后相关。

中心点:

ISAPL模型鉴定出两组临床预后存在显著差异的APL患者。

ISAPL模型或可用于鉴别需要进行不同监测和治疗的患者。

摘要:

Lucena-Araujo等人将突变分析和与急性早幼粒细胞白血病(APL)和急性髓系白血病预后不良相关基因的异常表达情况结合起来,提出一种APL综合得分 (ISAPL),并证实其与采用全反式维甲酸(ATRA)联合蒽环类药物化疗的患者的临床预后相关。

基于FLT3-ITD突变状态,ΔNp73/TAp73表达率,ID1、BAALC、ERG和KMT2E基因表达水平,研究人员在159名患者(ISAPL中间值 3分,范围0-10分)中建立ISAPL模型。ISAPL模型可区分两类不同的患者,这两类患者的早期死亡率、缓解情况、总体存活率、累积复发率、无病存活期和无事件存活期均存在明显差异。

总而言之,至少对于采用ATRA联合以蒽环类药物为基础的化疗治疗的患者,ISAPL模型或可鉴别出需要不同治疗的患者,以最大限度地提高他们的治愈机会。
