摘要 目的分析人表皮生长因子受体-2(HER-2)在食管鳞癌患者中的表达情况及其对生存预后的影响,并通过多因素生存分析筛选出有效的生存预测指标。方法回顾性研究613例食管鳞癌患者临床随访资料。应用免疫组织化学方法检测食管癌石蜡切片HER-2蛋白表达情况,采用Pearson等级相关分析HER-2表达与性别、年龄、病理组织学分级(G)、淋巴结转移(N)、TNM分期等因素的相关性。采用2检验分析HER-2表达差异是否有统计学意义;采用比例危险率回归模型(Cox模型)对性别、年龄、病理组织学分级、淋巴结转移、TNM分期、HER-2等进行生存分析。结果 (1)共402例患者进行HER-2免疫组织化学检测。其中150例HER-2(++^+++),占37.3%;HER-2(-^+)252例,占62.7%。(2)HER-2表达与TNM分期具有相关性(r=0.114,P=0.024),淋巴结阳性患者HER-2表达率显著高于淋巴结阴性患者(40.22%vs 35.19%,P<0.001)。(3)613例患者1年生存率78.0%,3年生存率35.0%,5年生存率为20.6%。Cox模型多因素生存分析显示,HER-2表达对生存时间没有显著影响(P=0.767),对生存时间具有独立预后作用的因素为淋巴结转移及病理分级(P分别为0.000,0.024)。结论食管鳞癌患者淋巴结阳性患者HER-2表达率显著高于淋巴结阴性患者,但免疫组化检测HER-2(+)对生存结果的影响有限。淋巴结转移及病理分级具有独立的生存预测作用。
