摘要
目的:探讨由小剂量高三尖杉脂碱(Har)和阿糖胞苷(Ara-C)组成HA化疗方案,在老年急性髓系白血病(AML)治疗中的疗效。方法:对19例60岁及以上AML患者,采用Har1~2mg/d,第1~14d,Ara-C 25~50mg/d,第1~14d,静脉滴注,间隔21~28d再行第2疗程化疗。结果:19例中完全缓解(CR)10例,部分缓解(PR)4例,未缓解(NR)5例,不良反应主要为骨髓抑制和粒细胞缺乏所致的感染,无早期死亡病例。结论:小剂量HA方案可诱导白血病细胞分化和促进凋亡,对不能耐受标准剂量化疗的老年人AML患者,具有一定优势,既可减少标准剂量化疗所致的化疗相关性死亡,又可在一定程度上延长患者的生存期。
Objective：To investigate the efficacy of low-dose HA regimen（harringtonine and cytarabine）for elderly acute leukemia.Methods： A total of 19 AML elderly patients were enrolled.Eleven patients were male,and 8 were female.The HA regimen contained harringtonine（1~2mg/d,days 1 to 14） and cytarabine（25mg^50mg/d,days 1 to 14）,Interval of days 21 to 28 for the second chemotherapy.Results：In 19 elderly patients with acute leukemia,the total complete remission（CR） rate of them was 52.63%（10/19）,partial remission rate of them was 21.05%（4/19）,non-remission rate of them was 26.32%（5/19）,myelosuppression and infection due to neutropenia were the most frequent adverse effects,the early death were not observed in all patients.Conclusion： Low-dose HA regimen for elderly acute leukemia has certain advantages in the remission induction therapy,that can not tolerate the standard-dose chemotherapy in elderly patients with acute leukemia,which can reduce the related death of standard-dose chemotherapy,and to extend the survival of patients with the advantage of reducing early mortality.
