70年代以前,急性白血病(AL)的分类诊断工作进展缓慢。1976年FAB分类方案公之于世后,血液学界对AL的亚型分类日益重视。FAB分类的根据为细胞形态学(morphology,M)类型的辨认,主要是依靠瑞氏染色或姬姆萨染色与细胞化学染色技术加上光学显微镜观察,经过多年修正补充,目前除ALL仍分为三类外,ANLL已分为八类(M_0～M_7)。FAB分类法有很大实用价值,其推广应用大大促进
Before the 1970s, the classification of acute leukemia (AL) has progressed slowly. After the FAB classification program was published in 1976, the hematology community paid more and more attention to the subtypes of AL. FAB classification based on the morphological (M, M) type of identification, mainly by Wright’s stain or Giemsa staining and cytochemical staining techniques combined with optical microscopy, after years of amendments to add, in addition to ALL are still divided into Three categories, ANLL has been divided into eight categories (M_0 ~ M_7). FAB taxonomy has great practical value, its promotion and application greatly promoted
