Comprehensive Genetic Analysis Revealed Myeloid/Natural Killer (Nk) Cell Precursor Acute Leukemia As A Novel Distinctive Leukemia Entity
BLOOD(2020)
摘要
Introduction: Myeloid/Natural killer (NK) cell precursor acute leukemia (MNKPL) is a rare hematologic malignancy prevalent in East Asia. MNKPL is characterized by extramedullary involvement, immature lymphoblastoid morphology without myeloperoxidase (MPO) reactivity, the CD7+/CD33+/CD34+/CD56+/HLA−DR+ phenotype. MNKPL is classified as mixed phenotype acute leukemia, and not otherwise specified rare types (MPAL NOS rare types) in WHO classification. However, its characteristic clinical feature and undetermined genetic feature suggests that MNPKL leaves open the possibility of a new independent disease concept. Here, we report clinical features and genetic alterations in patients with MNKPL.
