FAB协作组骨髓增生异常症(MDS)新分类用词混乱。作者将MDS分类运用于可诊断为非典型白血病的病例,对其实用性进行探索。既往13年间136例急性白血病(AML)中诊断为非典型白血病17例和慢性粒单细胞白血病(CMMOL)3例,共20例。就初诊时血液学所见、临床表现及白血病的发展及预后进行探索。诊断非典型白血病的标准为:(1)骨髓增生减低(有核细胞数<5万);(2)骨髓与外周血中的原始细胞百分率低(骨髓<50%,外周血<10%);
FAB collaborative group myelodysplastic syndrome (MDS) a new classification chaos. The authors apply the MDS classification to cases diagnosed as atypical leukemia and explore their utility. In the past 13 years, 136 cases of acute leukemia (AML) were diagnosed as atypical leukemia in 17 cases and chronic myelomonocytic leukemia (CMMOL) in 3 cases, a total of 20 cases. On the first visit hematology, clinical manifestations and leukemia development and prognosis to explore. The criteria for diagnosis of atypical leukemia are: (1) a reduction in myeloproliferation (<50,000 nucleated cells); (2) a low percentage of blasts in bone marrow and peripheral blood (<50% bone marrow and <10% peripheral blood);
