本文总结了38例MDS的血象与骨髓象特征:全血细胞减少与二系血细胞减少占83.4％,有16.6％表现为贫血,未见单独粒细胞减少或血小板减少者。73.6％的病例外周血见幼红细胞。各型MDS之骨髓有程度不一的三系增生异常,但以红系增生异常的情况较常见,RA与SRA两型常以此为主要表现。全组45％的病例红系尚有不同程度的巨幼样变。粒系以增生减低多见。半数病例见小巨核细胞,但小巨核在RA与SRA两型则不易见到。本组病例未见Ⅰ型与Ⅱ型原始细胞增多,而见早幼粒或幼单增多,此后转为急白,因而我们认为,除协作组规定的Ⅰ型与Ⅱ型原始细胞外,也应考虑早幼粒或幼单增多的意义。
This article summarizes the 38 cases of MDS blood and bone marrow imaging features: pancytopenia and secondary hematocytopenia accounted for 83.4%, 16.6% showed anemia, no single neutropenia or thrombocytopenia. 73.6% of cases of peripheral blood see erythroblasts. The bone marrow of various types of MDS have varying degrees of three-line dysplasia, but erythroid hyperplasia is more common, RA and SRA two types often take this as the main performance. The whole group of 45% of cases of erythroid there are different levels of MBT. Granulocyte hyperplasia to reduce more common. Half of the cases see the small megakaryocytes, but the small megakaryocytes in RA and SRA two types are not easy to see. This group of patients did not see the type Ⅰ and type Ⅱ primitive cells increased, and see the promyelocytic or young single increased, then became acute white, and therefore we believe that, in addition to the cooperative group of type Ⅰ and type Ⅱ primitive cells should Consider the significance of an increase in promyelocytic or semen.
