Abstract

Acute myeloid leukemia (AML) poses significant challenges due to its high relapse rates despite initial successful induction chemotherapy. Maintenance therapy aims to prevent disease recurrence, particularly in high-risk patients. This review explores current maintenance treatments, their impacts on patient outcomes, and ongoing studies shaping the treatment landscape for AML. Hypomethylating agents like azacitidine and decitabine have shown promise in improving relapse-free and overall survival, particularly in older patients with AML ineligible for transplantation. Combination regimens involving azacitidine and venetoclax have demonstrated encouraging outcomes post–hematopoietic stem cell transplantation. Targeted therapies, particularly FLT3 inhibitors like midostaurin and quizartinib, have shown significant benefits in improving survival outcomes, especially in FLT3-mutated AML cases. Gilteritinib and sorafenib also exhibit the potential to reduce relapse rates post-transplant. Isocitrate dehydrogenase inhibitors, including ivosidenib and enasidenib, present novel options for postchemotherapy and posttransplantation maintenance. Immunotherapies, such as Wilms tumor 1 peptide-based vaccines and checkpoint inhibitors, are being explored, although results vary. Despite ongoing research, the role of maintenance chemotherapy remains uncertain, with inconsistent outcomes across trials. The approval of oral azacitidine represents a significant advancement, emphasizing the need for further investigation into personalized maintenance approaches. In conclusion, the evolving landscape of maintenance therapy and integrating targeted therapies in AML offers promising avenues for improving patient outcomes.
