ｔ(8 ;2 1) (ｑ2 2 ;ｑ2 2 )是与急性髓性白血病Ｍ2 亚型 (ＡＭＬ Ｍ2 )相关的特异性染色体重排 ,因此第 2届国际形态学、免疫学和细胞遗传学 (ＭＩＣ)分型会议将其定义为Ｍ2 /ｔ(8;2 1) [1] 。国内有关儿童ＡＭＬ的ｔ(8;2 1)报道较少。近年我们检测出Ｍ2 /ｔ(8;2 1)型儿童ＡＭ
t (8; 2 1) (q2 2; q2 2) is a specific chromosomal rearrangement associated with acute myeloid leukemia M2 subtype (AML M2), so the 2nd International Symposium on Morphology, Immunology and Cytogenetics MIC) typing conference defines it as M2 / t (8; 2 1) [1]. Domestic children’s AML t (8; 2 1) reported less. In recent years, we detected M2 / t (8; 2 1) -type children’s AM
