Bcl-2、CD10、CD34、CK15表达在基底细胞癌和毛发上皮瘤鉴别诊断中的意义
Journal of Diagnosis and Therapy on Dermato-venereology(2019)
Abstract
目的:观察Bcl-2、CD10、CD34、CK15在基底细胞癌(BCC)和毛发上皮瘤(TE)中的表达,探讨其在两种肿瘤诊断和鉴别中的作用.方法:对确诊的36例BCC和16例TE石蜡包埋标本行Bcl-2、CD10、CD34、CK15免疫组化染色,观察其在肿瘤细胞及其周围间质中的表达.结果:在BCC和TE中表达的阳性率分别为Bcl-2(栅栏状模式):0、68.75%;CD10(肿瘤细胞染色):72.22%、12.50%;CD10(间质染色)2.78%、62.50%;CD34:0、12.5%;CK15:5.56%、56.25%,其中Bcl-2、CD10、CK15表达差异有统计学意义(P值均<0.01),而CD34表达差异无统计学意义(P>0.05).灵敏度:CD10(肿瘤细胞染色)72.22%>Bcl-2(68.75%)>CD10(间质染色)62.50%>CK15(56.25%).特异性:Bcl-2(100%)>CD10(间质染色)97.22%>CK15(94.44%)>CD10(肿瘤细胞染色)87.50%.准确度:Bcl-2(90.38%)>CD10(间质染色)86.54%>CK15(82.69%)>CD10(肿瘤细胞染色)65.38%.阳性预测值:Bcl-2(100%)>CD10(肿瘤细胞染色)92.86%>CD10(间质染色)90.91%>CK15(81.82%).阴性预测值:Bcl-2(87.80%)>CD10(间质染色)85.37%>CK15(82.92%)>CD10(肿瘤细胞染色)58.33%.结论:Bcl-2、CD10在BCC和TE中表达模式的差异,以及CK15在TE中高表达,有助于这两种肿瘤的鉴别诊断,CD34对于鉴别BCC和TE意义不大.
