摘要 目的:应用两种荧光原位杂交(FISH)试剂盒检测乳腺癌组织HER2基因状态,旨在比较两者在信号的强度和染色结果上的差异。方法:采用美国PathVysis和北京金普嘉公司生产的FISHHER2检测试剂盒检测10例免疫组化(IHC)HER2蛋白2+以上HER2的基因状态。结果:PathVysis公司试剂盒在荧光显微镜下观察:细胞核红绿信号清晰,可以采集比较好的图片,容易进行细胞计数;北京金普嘉公司试剂盒在荧光显微镜下观察:细胞核红色信号清晰,绿色信号不明显。结论:PathVysis公司试剂盒HER2和17号染色体信号强,稳定性好,重复性强;北京金普嘉公司试剂盒,简单快速,成本低,对HER2基因不扩增或高度扩增的病例不影响结果判读;当HER2基因与17号染色体比值为临界值时(1.8-2.2)或17号染色体为多倍体的病例,应采用PathVysis公司试剂盒。
