Acute myeloid leukemia (AML) comprises a heterogeneous group of hematopoietic cell neoplasms of myeloid lineage that arise from the clonal expansion of their precursors in the bone marrow, interfering with cell differentiation, leading to a syndrome of bone marrow failure. AML is a consequence of genetic and epigenetic changes (point mutations, gene rearrangements, deletions, amplifications, and arrangements in epigenetic changes that influence gene expression) in hematopoietic precursor cells, which create a clone of abnormal cells that are capable of proliferating but cannot differentiate into mature hematopoietic cells or undergo programmed cell death. The diagnosis requires more than 20% myeloid blasts in the bone marrow and certain cytogenic abnormalities. Treatment will depend on age, comorbidities, and cytogenetic risk among the most frequent.
急性髓系白血病(AML)是一组异质性的造血细胞肿瘤,起源于骨髓中前体细胞的克隆性扩增,干扰细胞分化,导致骨髓衰竭综合征。AML 是造血前体细胞中遗传和表观遗传变化(点突变、基因重排、缺失、扩增和影响基因表达的表观遗传变化的排列)的结果,这些变化产生了一个异常细胞克隆,这些细胞能够增殖,但不能分化为成熟的造血细胞或经历程序性细胞死亡。诊断需要骨髓中超过 20%的髓样母细胞和某些细胞遗传学异常。治疗将取决于年龄、合并症和最常见的细胞遗传学风险。
