Mixed-Phenotype Acute Leukemia Transforming Into Acute Myelomonocytic Leukemia (AML M4): A Case Report and Therapeutic Challenges. (PubMed, Cureus)
Hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (Hyper-CVAD) induction achieved morphological complete remission, but measurable residual disease (MRD) persisted. Consolidation with mini-cyclophosphamide, vincristine, and dexamethasone (mini-CVD) and prednisone, vincristine, methotrexate, and 6-mercaptopurine (POMP) maintenance failed to eradicate MRD, and overt relapse occurred at month 7. Nelarabine salvage was initiated...Early molecular risk stratification and deployment of targeted agents, venetoclax-based combinations, or timely allogeneic transplantation should be considered before irreversible genomic complexity emerges. Prospective studies tailored to high-risk cytogenetic subsets of MPAL are urgently needed.
