摘要 目的探讨荧光原位杂交技术(FISH)检测儿童急性淋巴细胞白血病(ALL)MLL基因重排及BCR/ABL融合基因的临床价值。方法利用荧光原位杂交技术和常规染色体核型分析技术对57例初诊ALL患儿MLL[t(11q;v)]和BCR/ABL[t(9;22)]进行检测,并且追踪其临床预后。结果 57例初诊ALL患儿中,MLL基因重排的阳性率为24.6%(14/57),BCR/ABL阳性率为8.8%(5/57),染色体核型分析未检出t(11q;v)和t(9;22)异常,阳性组总的缓解率较阴性组低。结论 MLL基因重排和BCR/ABL融合基因是儿童ALL预后不良的危险因素,常规染色体分析检出率较低,FISH技术可以显著提高检出率,在协助临床制定儿童ALL治疗方案及判断预后中具有重要价值。
