However, there is a lack of studies comparing the efficacy and safety of prophylactic versus preemptive DLI in patients with refractory/relapsed (R/R) acute myeloid leukemia (AML), and its effectiveness in other myeloid neoplasms (MN, such as myelodysplastic syndromes with excess blasts, MDS-IB) remains unknown, particularly with a scarcity of data from randomized controlled trials. This multicenter, randomized controlled study aims to prospectively compare the efficacy and safety of prophylactic versus preemptive DLI in patients with R/R myeloid neoplasms undergoing allo-HSCT. The study will enroll patients with MN (including AML and MDS-IB, excluding Ph+ cases) undergoing allo-HSCT, who are in R/R status at the time of transplant and achieve MRD-negative remission at 1 month post-transplant. Eligible patients must have no evidence of graft-versus-host disease (GVHD) or controlled GVHD, no severe infections, and no organ failure within 30-60 days post-transplant. One hundred patients will be enrolled in both the experimental and control groups. The primary endpoint is the relapse rate at 1 year post-randomization. Secondary endpoints include: 1-year leukemia-free survival and overall survival, and the incidence of bone marrow suppression, pancytopenia, GVHD, and infections following DLI. This study aims to explore strategies to reduce relapse rates and improve survival in patients with R/R MN following allo-HSCT.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Eligible patients were those who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) for myeloid neoplasms (MN), excluding Philadelphia chromosome-positive (Ph+) disease, regardless of age.
