Summary: This clinical trial included 30 cases and aimed to understand the effectiveness and safety of the VMAC regimen combined with donor lymphocyte infusion (DLI) in the treatment of patients with acute myeloid leukemia who have relapsed after allogeneic hematopoietic stem cell transplantation. The main questions it aims to answer are: The safety and efficacy of VMAC combined with DLI in the treatment of allo HSCT recurrence in AML patients;

Detailed description: venetoclax 400 mg/d (reduced to 100 mg when combined with an azole), d1-7; liposomal mitoxantrone 30 mg/m2/d, d1; cytarabine (Ara-C) 100 mg/m2/d, d1-7; cyclophosphamide (CY) 400 mg/m2/d, d2, 5)，and then rest for 1 day before giving cryopreserved donor stem cells.MNC1-2X10^8/kg infusion, low-dose (25 mg Bid), short-course treatment (2-3 weeks after DLI) oral cyclosporine (CSA) is added to prevent graft-versus-host disease starting 3 days before the infusion of cryopreserved stem cells. Monitor the occurrence of serious infections, cardiac toxicity, GVHD and other adverse reactions during the medication process; Blood routine recovery or bone marrow re examination 4 weeks after DLI to evaluate the efficacy of one course of VMAC combined with DLI; The patient was followed up for 2 years to evaluate long-term efficacy.

An informed consent form must be signed before the start of the research procedure, and the patient himself or his immediate family members must sign the informed consent form. Considering the patient's condition, if the patient's signature is not conducive to the treatment of the condition, the legal guardian or the patient's immediate family member will sign the informed consent form.
