小剂量三尖杉酯碱和阿糖胞苷联合粒细胞集落刺激因子治疗老年急性髓细胞白血病疗效观察

目的探讨小剂量三尖杉酯碱（HT，H）和阿糖胞苷（Ara-c,A）联合粒细胞集落刺激因子（G-CSF）治疗老年人急性髓细胞白血病的疗效及不良反应。方法35例AML患者均给予HT1mg·m^-2·d^-1，静脉滴注，第1—14天；Ara—c 10mg·m^-2，静脉滴注，每12h注射1次，第1～14天；G-CSF100—200μg·m^-2·d^-1，皮下注射，在第1次注射Ara—c之前开始使用，至最后1次注射Ara-c之前停用。结果35例AML患者化疗后完全缓解16例（46％）、部分缓解14例（37％），总有效率83％，未缓解（NR）5例（14％）；2例患者化疗期间死亡。主要不良反应为骨髓抑制。结论小剂量HA方案联合G—CSF治疗老年人急性髓细胞白血病安全、有效。

Effect of low-dose harringtonine and cytarabine in combination with granulocyte colony-stimulating factor on elderly patients with acute myelogenous leukemia

Objective To evaluate the efficacy and toxicity for the protocol of low-dose harringtonine and cytarabine(HA regimen)in combination with granulocyte colony-stimulating factor(G-CSF)in elderly patients with acute myelogenous leukemia(AML).Methods Thirty-five AML patients were treated with HAG including low-dose chieved PR.The overall response rate was 83%.5 of 35(14%)was non-remiasion.Two patients died in the duration of treatment.The main complication of chemotherapy is myelosuppresion.Conclusion Low-dose HA regimen in combination with G-CSF is effective and safe in elderly patients with AML.
