骨髓增生异常综合征(myelodysplastic synd-rome,MDS)是以骨髓病态造血,致外周血细胞质和量异常的一组血液病。由于其血液学的表现多样,又缺乏特异性,与某些造血系统疾病易混淆,故以往名称混乱。FAB协作组(1976、1981年)建议使用MDS这一名称,并从形态学上将其归纳为5种类型及诊断标准,从而结束了过去的混乱局面,为研究本综合征提出了统一的概念和依据。但目前尚有两种争议;一是认为这种骨髓增生异常既非正常细胞增生,又非白血 Myelodysplastic syndrome-myelodysplastic syndrome (MDS) is a group of hematological disorders characterized by abnormal hematopoiesis and abnormal cytoplasm in the bone marrow. Because of its heterogeneous hematology performance, lack of specificity and confusion with certain hematopoietic disorders, the previous name was confusing. The FAB collaborative group (1976, 1981) recommended the use of the name MDS and morphologically classified it into five types and diagnostic criteria, thus ending the chaos of the past and proposing a unified concept for the study of the syndrome And based on. But there are still two kinds of controversy; one is that this myelodysplastic abnormalities are neither normal cell proliferation, nor white blood
