摘要 目的:探讨卵巢癌患者血清人附睾蛋白4(human epididymis protein4,HE4)水平变化的临床意义。方法:用酶联免疫吸附试验法测定82例卵巢癌患者血清HE4水平,并同步检测糖类抗原125(CA125)水平,与143例卵巢良性疾病患者和40例健康体检者进行对照比较。计算敏感性、特异性等诊断性指标,绘制ROC曲线,计算ROC曲线下面积。结果:卵巢癌组血清HE4、CA125水平均显著高于健康对照组(P<0.01),其中收集到31例手术或化疗后1个月数据复查,血清HE4、CA125水平与治疗前均已显著性下降(均P<0.01);其卵巢良性疾病组与健康对照组之间差异均无显著性。HE4对卵巢癌的诊断敏感性为82.93%(68/82),特异性为94.54%(173/183),均高于CA125;HE4的ROC曲线下面积最大(0.949;95%CI为0.915~0.982),临床诊断效能优于CA125。相关性分析显示卵巢癌患者HE4水平与CA125水平呈显著正相关(r=0.505,P<0.01)。结论:HE4与卵巢癌联系密切,显示了较高的敏感性和特异性,其能成为一个的新卵巢癌诊断和评价治疗效果的标记物。
