急性非淋巴细胞白血病(ANLL)是一种起源于不同阶段造血干细胞的克隆性疾病。染色体研究对ANLL的诊断分型、治疗选择、预后判断以及病因和病机的探讨均有重要的意义,因而日益受到血液学和遗传学工作者的重视。兹将近年来这些方面的研究进展综述如下。一、染色体检查已成为协助ANLL诊断分型的重要工具 Acute nonlymphocytic leukemia (ANLL) is a clonal disease that originates from hematopoietic stem cells at various stages. Chromosome studies have important implications for the diagnosis of ANLL, the choice of treatment, the prognostic judgment and the etiology and pathogenesis, and are therefore increasingly valued by hematology and genetics practitioners. The research progress in these fields in recent years is as follows. First, chromosome examination has become an important tool to assist in the diagnosis of ANLL
