    摘要:

    目的 评价杂交捕获二代(HC-II)和实时荧光定量PCR (real-time PCR)两种人乳头瘤病毒(HPV)检测法的一致性;探讨两法筛查宫颈癌及其癌前病变的敏感性和阴性预测值; 为实时荧光定量PCR试剂盒的应用提供临床资料。方法 对877名就诊的妇女用HC-II和real-time PCR两种方法检测HPV,并进行宫颈液基细胞学检查(LCT),其中任一结果异常者再进行组织病理检查。结果 877名妇女中有804名两种HPV检测法结果一致,总符合率达91.7%,一致性检验Kappa值为0.792。在对高级别宫颈上皮内瘤样病变(CIN)的检测中,HC-II和real-time PCR的敏感性分别为96.7%和94.6%,阴性预测值分别为99.5%和99.2%。结论 real-time PCR与HC-II 检测具有很好的一致性,可用于宫颈癌及其癌前病变的筛查。

    Abstract:

    Objective To investigate the accordance of Hybrid Capture-II (HC-II) and real-time fluorescent PCR in detecting high-risk human papillomavirus (HR-HPV) DNA in cytological cervical samples and to investigate the sensitivity and negative predictive values of the two assays in screening high-grade cervical intraepithelial neoplasm. Methods HR-HPV DNA was in parallel detected with HC-II and real-time PCR in 877 cytological samples from women underwent liquid-based cytological test. For the patients with the abnormal cytological results or positive HR-HPV DNA, biopsy was performed. Results The two HR-HPV DNA detection methods showed concordant results in 804 of 877 cervical samples (91.7%, Cohen’s Kappa = 0.792). For the detection of the high-grade cervical intraepithelial neoplasia, the sensitivity of HC-II and real-time PCR was 96.7% and 94.6%, respectively, and the negative predictive values were 99.5% and 99.2% respectively. Conclusions Real-time PCR has good accordance with HC-II for HR-HPV DNA detection and can been used in cervical cancer screening.
