摘要 目的:观察程序性死亡蛋白配体1(PDL1)和Ki67在三阴性乳腺癌中的表达及与临床病理因素的相关性。方法:应用免疫组织化学法检测151例三阴性乳腺癌、137例非三阴性乳腺癌、48例正常乳腺组织中PDL1和Ki67的蛋白表达情况,结合临床病理资料综合分析其临床意义。结果:PDL1和Ki67分别在乳腺癌细胞的细胞质和细胞核表达。在151例三阴性乳腺癌中PDL1阳性表达98例(64.90%),阳性率高于非三阴性乳腺癌(χ2=5.633,P<0.05)和正常乳腺组织(χ2=106.471,P<0.001),Ki67阳性表达121例(80.13%),阳性率高于非三阴性乳腺癌(χ2=4.460,P<0.05)和正常乳腺组织(χ2=154.717,P<0.001),差异有统计学意义。在三阴性乳腺癌组织中,PDL1阳性较PDL1阴性患者组织学分级高、伴淋巴结转移与远处转移的多,差异有统计学意义(均P<0.05),患者年龄、肿块大小、是否绝经组间差异均无统计学意义(均P>0.05);Ki67阳性患者较Ki67阴性患者组织学分级高、伴淋巴结转移与远处转移的多,差异有统计学意义(均P<0.05),患者年龄、肿块大小、是否绝经组间差异均无统计学意义(均P>0.05)。结论:检测PDL1和Ki67对判断三阴性乳腺癌发展和预后有一定价值。
