摘要 目的应用八探针间期荧光原位杂交技术(FISH)联合染色体核型分析观察急性淋巴细胞白血病(ALL)成人患者与儿童患者的细胞遗传学差异。方法对125例ALL患者(成人86例、儿童39例)全部行八探针FISH(MYC、P16、E2A、TEL/AML1、BCR/ABL、MLL、IGH、多倍体的DNA探针)检测并染色体核型分析。结果八探针FISH检测结果显示,成人ALL患者与儿童ALL患者的TEL/AML1融合基因、BCR/ABL融合基因与多倍体阳性率之间的差异有统计学意义(P<0.05);染色体核型分析成人ALL患者与儿童ALL患者的(t9;22)易位、多倍体阳性率之间的差异有统计学意义(P<0.05)。结论成人ALL患者与儿童ALL患者融合基因表达各有侧重,不同的细胞遗传学特征与其预后密切相关。FISH多探针诊断系统检测ALL患者常见遗传学异常省时、准确、高效,与染色体核型分析形成很好的互补。 Objective To investigate the cytogenetic differences between children and adults with acute lymphoblastic leukemia（ALL） using eight-probe fluorescence in situ hybridization and karyotype analysis.Methods Eight-probe（MYC,P16,E2A,TEL/AML1,BCR/ABL,MLL,IGH,and hyperdiploidy） fluorescence in situ hybridization and karyotype analysis were performed for 86 adults and 39 children with acute lymphoblastic leukemia.Results Eight-probe fluorescence in situ hybridization showed significant differences in the positivity rate of TEL/AML1,BCR/ABL,and hyperdiploidy between adult patients and children with ALL.By karyotype analysis,the positivity rate of t（9;22） and hyperdiploidy differed significantly between the children and adult patients（P0.05）.Conclusion Adults and children with ALL have different expression profiles of the fusion genes.Eight-probe fluorescence in situ hybridization is time-saving,accurate and efficient in detecting common genetic abnormalities in ALL patients,and can be well complementary to karyotype analysis in clinical diagnosis of ALL.
