摘要 目的分析透射电子显微镜(电镜)对急性髓系白血病(AML)诊断分型的临床符合率。方法回顾性分析793例AML患者经电镜、细胞形态学、细胞化学、流式细胞术、分子生物学和染色体核型等方法分型结果,比较电镜及其他检测方法对AML分型与临床诊断的符合率,分析电镜对AML分型的优势。结果6种检测方法AML分型符合率由高到低依次为电镜检测(63%)、细胞化学分析(59%)、细胞形态学分析(52%)、流式细胞术分析(47%)、染色体核型分析(26%)和分子生物学检测(23%)。电镜检测对M1、M2a、M4、M5、M6、M7、t(8;21)和t(15;17)亚型的符合率分别为39%、34%、17%、74%、50%、73%、87%和89%。结论电镜对AML分型的临床符合率明显高于其他方法,其中对t(15;17)、t(8;21)、M7、M5和M6有很强诊断筛查作用,对M1、M2a和M4分型与临床诊断符合率较低。 Objective To analyze coincidence rate of acute myeloid leukemia (AML) sub-typing be- tween transmission electron microscopy (TEM) and clinical discharge diagnosis. Methods Reviewing sub- typing results of TEM, light microscopy, flow cytometric analyzing, molecular biological detection and karyo- type in 793 AML cases, comparing their coincidence rates with discharge diagnosis to reveal advantages of AML sub-typing by TEM. Results General coincidence rates of TEM, light microscopy, flow cytometric an- alyzing, molecular biological detection and karyotype on AML sub-typing were 63% , 59%, 52%, 47% , 26% and 23% respectively, and clinical coincidence rates of TEM on M1, M2,, Mg and Ms, M6, M7, t (8; 21 ) and t ( 15 ; 17.) were 39%, 34%, 17%, 74%, 50%, 73%, 87% and 89% respectively. Conclusion TEM has a higher coincidence rate in general AML sub-typing, especially strong screenings on t ( 15 ; 17 ), t (8; 21 ) , M7, Ms and Mr, but lower coincidence rates on M1 ,M2a and M4 sub-typing than other methods.
