摘要 目的探讨食道癌的肿瘤坏死因子受体配体(h GITRL)表达差异的临床病理相关性及其在预测患者预后中的临床指导价值。方法采用Western印迹方法检测112例食道癌临床组织样本和101例配对癌旁食道h GITRL的蛋白表达,酶联免疫吸附(ELISA)法检测38例食道癌患者、12例食道异常增生患者和20例健康自愿者的血清h GITRL蛋白水平,分层分析与食道癌病理参数的相关性,进一步生存分析h GITRL表达与临床预后的关系。结果食道癌组织中h GITRL蛋白条带灰度值较癌旁食道组织显著增高(P<0.001),且血清h GITRL阳性率为食道癌>食道异常增生>正常食道(P<0.05);食道癌h GITRL的高表达与淋巴结转移和临床分期显著相关(P<0.001);进一步生存分析发现h GITRL阳性表达者的3年、5年无瘤生存率和生存期,均较阴性者明显降低(P<0.05),Cox生存风险模型示h GITRL可能是食道癌患者3年无瘤生存预后的独立危险因素(P=0.029,<0.05)。结论 h GITRL可能成为食道癌早期诊断的生物学标志物,且可能具有预测食道癌患者3年无瘤生存预后的重要临床价值,但尚待大样本临床研究证实。
