更高强度的骨髓清除疗法并不能为老年AML患者提供更好的存活预后。

摘要:

老年AML患者进行骨髓移植前的最佳调理方案尚不明确。在本研究中,研究人员对比了60岁以上的AML患者在其机构接受AHCT治疗的结果。

共404位患者,采用的治疗方式有以下四种:1)氟达拉滨+美法仑 100mg/m2(FM100);2)氟达拉滨+美法仑 140mg/m2(FM140);3)氟达拉滨+ IV 白消安,血药浓度-时间曲线下面积(AUC)≥5000/日 x 4日(白消安≥20000);4)氟达拉滨+ IV 白消安,AUC 4000/日 x 4日(白消安16000)。采用倾向评分分析(PSA)来比较这四组的预后。

对于这四种调理方案,FM100组的长期存活率最好,5年无进展存活率为49%,另外三组分别是30%、34%和23%。FM100方案的好处主要是采用该方案调理的患者的非复发死亡率较低,而且在表现状态较差的患者中效果更明显。PSA证实FM100组的移植后存活率更好,而其他组间无明显差异。

总而言之,老年AML患者可从低美法仑剂量的强度降低的调理方案中获益,存活预后更好,虽然该方案主要用于那些不能接受更高强度调理方案的患者。
