Abstract
The treatment of young patient with acute myeloid leukemia (AML) has improved dramatically during the past several decades. However, management of elderly patients with AML still remains a challenge. A total of 56 elderly patients with de novo AML were treated with homoharringtonine and cytarabine in combination with granulocyte colony-stimulating factor (HCG). The overall response rate was 75% (60.7%% complete response [CR] and 14.3% partial response). Fourteen (25%) of the 56 patients showed no response. A higher CR rate was observed in patients aged < 70 years, with better-risk or intermediate-risk karyotype and with NPM1 mutations. To the date of the last follow-up, the median overall survival (OS) was 12.0±1.7 months. There were significant correlations of OS with age, initial karyotype, performance status and gene mutations (NPM1,FLT-ITD and DNMT3A) at diagnosis. The early death rate was 7.1%. Hematologic toxicity was well tolerated; and severe non-hematologic toxicity was not observed.
