近年来国内外都注意到一组疾病,多为老年患者,临床的主要症状为贫血,有时有感染和出血现象,血像示全血细胞减少,或任一、任二系血细胞减少;骨髓增生活跃或明显活跃,三系血细胞有显著的病态造血,原始粒细胞或早幼粒稍增加,偶尔还出现于血循环中,但还不足以诊断为白血病。用铁剂或各种生血素治疗不易生效,病程漫长,如不死于感染或出血,多演变为白血病,这就是本文所要讨论的骨髓增生异常综合征,或称之为白血病前期(白前)。
In recent years, both at home and abroad have noticed a group of diseases, mostly elderly patients, the main clinical symptoms of anemia, and sometimes infection and bleeding, blood imaging shows pancytopenia, or any, any two series of cytopenias; active bone marrow hyperplasia Or significantly active, three lines of blood cells significantly morbid hematopoietic cells, primitive granulocytes or promyelocytic slightly increased, and occasionally also appears in the blood circulation, but not enough to diagnose leukemia. With iron or a variety of hematinol treatment is not easy to take effect, long course, such as not died of infection or bleeding, and more evolved into leukemia, which is discussed in this article myelodysplastic syndrome, or pre-leukemia (pre-white).
