The purpose of the study is to determine whether Fludarabine in combination with cytarabine is more effective than high-dose cytarabine in post-remission therapy for patients with core-binding factor acute myeloid leukemia

The recurrence rate, relapse-free survival rate, and overall survival rate of CBF-AML patients were compared between FA and HIDAC regimens. Observe the prognostic value of factors such as c-KIT gene mutation and minimal residual disease (MRD).

Inclusion Criteria:

• Clinical and laboratory diagnosis of CBF-AML,including RUNX1-RUNX1T1 and CBF-MYH11 fusion gene rearrangement by PCR/FISH
• In status of complete remission after one to two courses of induction therapy
• Total bilirubinic acid ≤ 35μmol/L, AST/ALT<2 times abnormal level, serum creatinine < 1.5mg/ml
• Cardiac function: EF ≥ 50%
• Hydroxyurea can be used for patient with white blood cell count ≥ 50*109/L
• ECOG (Eastern Cooperative Oncology Group) score: ≤ 2

Exclusion Criteria:

• Relapsed/refractory AML
• Serious liver/ kidney dysfunction
• Cardiac function level: 2 above
• Female in pregnancy or lactation
• With serious infection diseases or other diseases
• Not obey the principle of clinical study
