1976年FAB协作组在讨论急性白血病(急白)分类建议时,提出了易与急白混淆的骨髓增生异常综合征(Mgelodysplas-tie Syndromes简称MDS)并将其分为“有过多原始细胞的难治性贫血”,与”慢性粒-单核细胞白血病”两型。前者包括“白血病前期”、“冒烟型白血病”,“非典型白血病”等等。以后发现前述两型不能概括不同类型的MDS,当时也未确定MDS具有预后意义,或发展为急自趋势的特征,因而于1982年提出MDS新的诊断标准,将其分为5型。本文根据此新标准,将我院血液室1974-1984年所见38例的资料分析报告如下:
In 1976, when discussing the classification of acute leukemia (acute white), the FAB collaborative group proposed Mgelodysplas-tie Syndromes (MDS), which is easily confused with acute whiteness and classified it as “having too many primitive cells Refractory anemia ”, and“ chronic granulocyte-monocytic leukemia ”two types. The former includes “pre-leukemia,” “fuming leukemia”, “atypical leukemia” and so on. Later found that the two types can not be summarized in different types of MDS, MDS was also not determined at the time the prognostic significance, or the characteristics of rapid development of the trend, which in 1982 proposed a new MDS diagnostic criteria, divided into 5 types. According to this new standard, the data analysis report of the 38 cases seen in our blood bank from 1974 to 1984 is as follows:
