Acute myeloid leukemia (AML) represents a malignant accumulation of immature myeloid cells in the marrow, presenting with impaired hematopoiesis and its attendant complications, including bleeding, infection, and organ infiltration. Chromosomal abnormalities remain the most powerful predictors of AML prognosis and help to identify a subgroup with favorable prognosis. However, the majority of AML patients who are not in the favorable category succumb to the disease. Therefore, better efforts to identify those patients who may benefit from more aggressive and investigational therapeutic approaches are needed. Newer molecular markers aim at better characterizing the large group of intermediate-risk patients and to identify newer targets for therapy. A group that has seen little improvement over the years is the older AML group, usually defined as age ≥ 60. Efforts to develop less intensive but equally efficacious therapy for this vulnerable population are underway.
急性髓系白血病(AML)是骨髓中不成熟髓系细胞的恶性积聚,表现为造血功能受损及其伴随的并发症,包括出血、感染和器官浸润。染色体异常仍然是 AML 预后的最有力预测因素,并有助于确定具有良好预后的亚组。然而,大多数不属于有利类别的 AML 患者最终会死于该疾病。因此,需要更好地努力识别那些可能受益于更积极和探索性治疗方法的患者。新的分子标志物旨在更好地描述大量中危患者,并确定新的治疗靶点。近年来,一个改善甚微的群体是年龄较大的 AML 患者,通常定义为年龄≥60 岁。目前正在努力为这一脆弱人群开发不那么密集但同样有效的治疗方法。
