Abstract

With limited data available on the low-dose cytarabine, aclarubicin and granulocyte colony-stimulating factor (CAG) regimen in newly diagnosed older patients with acute myeloid leukemia (AML), this study aimed at comparing the efficacy and toxicity of CAG with idarubicin plus cytarabine (IA) remission induction therapy in these patients. A total of 154 consecutive patients (52 with CAG and 102 with IA) were retrospectively analyzed. The patients in the CAG group had a higher median age (68 vs. 65 years, p = 0.002) and a higher proportion of previous myelodysplastic syndrome (25.0% vs. 2.9%, p < 0.0001) compared to those in the IA group. The complete remission rates with the CAG and IA regimens were 55.8% and 52.9% (p = 0.864). The median overall survival (12.1 vs. 11.7 months, p = 0.650) and 3-year disease-free survival rates (29.6% vs. 48.6%, p = 0.657) were not statistically different in the two groups. The CAG regimen might be an alternative to conventional chemotherapy in older patients with AML.
