摘要 目的观察肺腺癌组织甲状腺转录因子1(TTF-1)表达变化,并分析其与表皮生长因子受体(EGFR)基因突变、患者预后的关系。方法肺腺癌患者192例,观察其TTF-1表达变化及EGFR基因突变情况,分析TTF-1阳性表达、EGFR基因突变与肺腺癌临床病理参数的关系,另采用Kaplan-Meier生存分析、Log Rank检验及Cox风险回归模型分析影响患者预后的因素。结果 192例患者中,TTF-1阳性表达157例(81.8%)、阴性表达35例(18.2%),EGFR基因突变型80例(41.7%)、野生型112例(58.3%)。TTF-1阳性表达与肺腺癌TNM分期相关,EGFR基因突变与肺腺癌患者性别、吸烟史相关,P均<0.05。157例TTF-1阳性患者中有79例(50.3%)发生EGFR基因突变,而35例TTF-1阴性患者中仅有1例(2.9%)发生EGFR基因突变,TTF-1阳性表达与EGFR突变有相关性(P<0.05)。单因素生存分析显示,TTF-1阳性、EGFR基因突变、年龄、PS评分、TNM分期与患者预后相关(P均<0.05)。多因素生存分析显示,TTF-1阳性、EGFR基因突变、TNM分期早期、PS评分0~2分是肺腺癌远期生存的独立影响因素(P均<0.05)。结论检测肺腺癌组织TTF-1表达情况有助于初步预测肺腺癌EGFR基因突变状态及判断患者预后。
