Intermediate-dose HAD Regimen for CEBPA Double-mutated AML

This is a prospective, randomized, controlled clinical trial of patients diagnosed with CEBPA double-mutated AML. Patients who meet the inclusion criteria are randomly assigned to receive the intermediate-dose HAD regimen or the conventional 3+7 induction regimen (IA or DA), respectively. When patients reach complete remission (CR) after the induction therapy, 3 courses of the high-dose cytarabine regimen (3g/m2 q12h, 3 days) are used. Hematopoietic stem cell transplantation is recommended for patients with persistent MRD positive after treatment. When patients do not achieve CR after the induction therapy, reinduction therapy with IAC (IDA 10mg/ m2 for 3 days, cytarabine 100mg/m2 for 7 days, cyclophosphamide 350mg/m2 d2, d5) regimen is used. Patients who still do not achieve CR after reinduction therapy will be removed from the group.
