三阴性乳腺癌（triple-negative breast cancer，TNBC）患者发生脏器转移和其他原发性非乳腺癌，尤其是肺癌的发病风险会增加。由于缺乏TNBC的典型免疫表型，TNBC转移灶与来自其他器官原发癌的鉴别诊断可能存在困难。我们分析了207例TNBC和152例原发性肺腺癌（lung adenocarcinomas，LA）中雌激素受体、孕激素受体、人类表皮生长因子受体、甲状腺转录因子-1（thyroid transcription factor-1，TTF-1）、NapsinA、乳腺球蛋白、巨大囊肿病液体蛋白15（gross cystic disease fluid protein 15，GCDFP15）、Sry相关HMg-盒基因10（Sry-related HMg-Box gene 10，SOX10）、GATA结合蛋白3（GATA-binding protein 3，GATA3）和雄激素受体的表达。所有检测的TNBC均不表达TTF-1和NapsinA。当TNBC与TTF-1阳性或阴性LA进行比较时，无论LA是否表达TTF1，SOX10作为1种支持TNBC诊断的标志物，其敏感性（62.3%）和特异性（100%）均最佳（P<0.0001）。GATA3具有中等敏感性（30.4%）和非常好的特异性（98.7%），在152例LA中只有2例（1.3%）被错误分类。GCDFP15具有中度敏感性（20.8%）和非常好的特异性（98%），在152例LA中只有3例（2%）被错误分类。乳腺球蛋白和雄激素受体具有中度敏感性（38.2%和30%），良好的特异性（81.6%和86%），152例LA中分别有28例和21例被错误分类。多因素分析中，能够区分SOX10阴性TNBC和TTF-1、NapsinA阴性LA的最佳标志物为GATA3（比值比=33.5；95%置信区间，7.3~153.5；P<0.0001）和GCDFP15（比值比=31.7；95%置信区间，6.9~145.6；P<0.0001）。207例TNBC中只有13例（6.3%）不表达上述标志物。根据我们的研究结果，在鉴别TNBC和TTF-1阴性LA时，抗体的选择顺序首先是SOX10，其次是GATA3，最后是GCDFP15。这一顺序对于有TNBC病史女性进行肺结节穿刺活检诊断尤为重要。
