骨髓增生异常综合征(MDS)是一组异质性、密切相关的获得性干细胞疾病。在过去的10年里,由于新的遗传学和分子技术的发展及细胞因子的临床应用,使 MDS 成为一个很有吸引力的课题。FAB 协作组将其分为5型:RA、RARS、RAEB、RAEB-t 及CMML。我们根据转为白血病的机会不同,称 RA Myelodysplastic syndrome (MDS) is a heterogeneous and closely related acquired stem cell disease. In the past 10 years, MDS has become an attractive topic due to the development of new genetics and molecular techniques and the clinical application of cytokines. FAB collaborative group will be divided into 5 types: RA, RARS, RAEB, RAEB-t and CMML. We are different according to the opportunity to switch to leukemia, said RA
