摘要 目的探讨程序性死亡因子配体1(PD-L1)在乳腺癌中的表达及其与患者临床病理参数、预后的相关性。方法购买乳腺癌组织芯片,用免疫组化的方法检测154例乳腺癌组织中PD-L1的表达,分析其与患者各项临床指标及预后的关系。结果 PD-L1在乳腺癌组织中表达阳性率为22.7%,PD-L1表达与乳腺癌患者T分期、N分期、ER受体、PR受体相关(P<0.05)。PD-L1阳性患者T、N分期高,且以ER、PR受体阴性为主。PD-L1阳性患者生存时间明显缩短(P=0.000)。多因素COX回归分析结果显示PD-L1是影响乳腺癌患者生存的独立因素(P=0.038)。结论 PD-L1与乳腺癌分期、生存时间、预后密切相关。
