OBJECTIVE: To evaluate the efficacy and safety of idarubicin combined with high-dose cytarabine as a post-remission therapy for elderly patients with acute myeloid leukemia (AML).
METHODS: From November 2017 to June 2021, 24 AML patients aged ≥60 years who were in complete remission for the first time were enrolled in consolidation chemotherapy with idarubicin (10 mg/m2 intravenously once for day 1) combined with high-dose cytarabine (1.5 g/m2 intravenously over 3 hours every 12 hours for day 1-3), and the efficacy and safety were observed.
RESULTS: Among the 24 patients, there were 12 males and 12 females, the median age was 65 (60-78) years old, and the median follow-up time was 23.3 (2-42.7) months. By the end of the follow-up, 15 patients relapsed and 11 patients died. The median disease-free survival (DFS) was 9 months and there were 3 cases of 2-year DFS. The median overall survival (OS) was 16.2 months, and there were 4 cases of 2-year OS. In terms of safety, 6 patients had grade 1-2 non-hematological adverse reactions, 12 patients had grade 3-4 hematological adverse reactions, and a total of 6 patients developed infection after consolidation chemotherapy. Multivariate analysis showed that two induction cycles and high-risk cytogenetic abnormalities were the adverse factors of DFS and OS in elderly patients with AML in this study.
CONCLUSION: For AML patients ≥60 years old in first complete remission, idarubicin combined with high-dose cytarabine as post-remission therapy has a better safety, but compared with other regimens does not improve the prognosis of elderly patients, which needs further exploration.
