Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has improved survival for patients with hematological malignancy, especially for those highly at risk of relapse. However, disease relapse after allo-HSCT remains the most common cause of treatment failure and death, even with conventional chemotherapy and donor lymphocyte infusion. Disease relapse in allo-HSCT can be reduced via pre-emptive treatment based on measurable residual disease and maintenance therapy for patients at high risk of relapse as promising treatment strategies. Recently, the development of novel agents and cellular therapies with high antitumor activity and less toxicity, which can be used in the post-transplant setting, has increased their clinical applications in the therapeutic approach. This review examines the current landscape and future strategies for maintenance therapy, mainly for AML and ALL after allo-HSCT.
