The Efficacy of Allogeneic Hematopoietic Stem Cell Transplantation in Newly Diagnosed High-relapse-risk CEBPA Mutant Acute Myeloid Leukemia

Inclusion Criteria

• •1. Patients with confirmed CEBPA mutant AML. Diagnostic criteria include the presence of CEBPA mutant gene detected at the molecular level;
• •2. Patients with high-risk molecular markers or gene mutations, or complex karyotypes for disease recurrence, or flow cytometry/gene MRD positivity after two chemotherapy treatments; high-risk molecular markers or gene mutations include: CD7 positive, WT1 mutation, non-bzip-inframe CEBPA mutation; The positive threshold for flow cytometry MRD was 0.0001%; The MRD threshold of molecular biology is the lowest value of the detection protocol of the center.
• •3. Medical history and diagnosis of MICM, exclusion of MDS, transformation and treatment-related AML;
• •4. Age 18-65 years old (18 years old ≤Age\< 65 years old);
• •5. Liver and kidney function: blood bilirubin ≤ 35 μmol/L, AST/ALT below 2 times the upper limit of normal, serum creatinine ≤ 150 μmol/L;
• •6. Normal cardiac function (EF≥50%, New York Cardiac Function Classification NYHA I/II);
• •7. Physical condition score 0-2 (ECOG score);
• •8. For patients with peripheral blood leukocytes \< 50\*109/L at the initial onset, no chemotherapy has been given except for hydroxyurea before the start of induction therapy;
• •9. For patients with peripheral blood leukocytes ≥ 50\*109/L at the initial onset, cytarabine and hydroxyurea are allowed to be treated before the start of induction therapy;
• •10. Non-pregnant and lactating women;
• •11. For all women of childbearing age, a pregnancy test must be performed to measure hCG to rule out pregnancy;
• •12. Obtain informed consent signed by the patient or family member.
