肿瘤标志物HE4中国人群参考值研究结果发布

2014-11-26 MedSci MedSci原创

人附睾蛋白4(human epididymis protein 4,HE4)作为一种新的肿瘤标志物,在良性疾病患者和正常人血清中含量极低,而在卵巢癌组织和患者血清中均高度表达。在日前上海举行的“血清肿瘤标志物在卵巢癌诊疗中的临床应用”研讨会上,解放军总医院田亚平教授首次公布了HE4中国人群参考值大型临床研究的结果。这一历时两年的多中心、大样本的临床研究,由解放军总医院、天津市肿瘤医院等9家医院联合

人附睾蛋白4(human epididymis protein 4,HE4)作为一种新的肿瘤标志物,在良性疾病患者和正常人血清中含量极低,而在卵巢癌组织和患者血清中均高度表达。在日前上海举行的“血清肿瘤标志物在卵巢癌诊疗中的临床应用”研讨会上,解放军总医院田亚平教授首次公布了HE4中国人群参考值大型临床研究的结果。

这一历时两年的多中心、大样本的临床研究,由解放军总医院、天津市肿瘤医院等9家医院联合开展,样本量超过2300例、覆盖了18~95岁的女性,旨在建立中国人群HE4水平的参考值范围,研究HE4对卵巢癌诊断的敏感性和特异性,以更好地指导Elecsys HE4检测结果的临床应用。

研究表明,目前中国表观健康女性HE4为105.10pmol/L且随年龄增长呈递增趋势,绝经后妇女较绝经前HE4水平有显著升高。田亚平表示,该研究为卵巢癌的诊断及筛查提供了大样本的中国健康人群的参考值;HE4联合糖链多肽抗原125(CA125)可将早期卵巢癌诊断的敏感度提高到92%;HE4检测有助卵巢癌的早期诊断、疾病复发和转移的风险评估及随访监测,显著提高患者生存率。

MedSci评:HE4作为一种潜在的新型肿瘤标志物,近年来在国际上引起广泛的重视。主要用于卵巢癌,非小细胞肺癌等肿瘤的鉴别诊断。相关文献如下:

大样本卵巢癌肿瘤标志物研究启动

  10月27日,解放军总医院、天津市肿瘤医院等9家大型三甲医院及肿瘤专科医院联合罗氏诊断,在京启动人附睾蛋白4(HE4)多中心、大样本临床研究。   据悉,HE4是一种与卵巢癌有关的新型肿瘤标志物,88%的卵巢癌患者都会出现HE4升高,因此HE4适用于卵巢癌的早期检测、鉴别诊断、治疗监测及预后评估。解放军总医院教授田亚平介绍说,国家食品药品监督管理局已批准国际先进的卵巢癌Elecsys HE4
