High-risk human papillomavirus (HR-HPV) persistence is thought to be necessary for the development of cervical cancer. Because not all cases of low-grade squamous intraepithelial lesion (LSIL) or higher-grade squamous intraepithelial lesion are associated with HR-HPV, detection of HR-HPV in women with these cervical abnormalities may be clinically useful for management. The aim of this study was to detect HR-HPV in women with LSIL or higher-grade cytology.
In a multicenter, prospective clinical study, residual liquid-based cytological specimens from 3,966 US women were analyzed. Women with LSIL or higher-grade cytology underwent colposcopy and cervical biopsy as clinically indicated. The test was used to detect HR-HPV in women with cytologically diagnosed LSIL or higher, with histological confirmation of cervical intraepithelial neoplasia 2 (CIN 2) or worse by a central review panel.
Among subjects with LSIL or higher-grade cytology and complete data sets, 11.8% (41/347) were diagnosed with CIN 2 or worse; 82.1% (285/347) were HR-HPV positive. The prevalence of CIN 2 or worse and CIN 3 or worse was 14.4% (41/285) and 7.0% (20/285), respectively, among subjects who were HR-HPV positive. All subjects diagnosed with CIN 2 or worse (41/41) and CIN 3 or worse (20/20) tested positive for HR-HPV. Sensitivity and negative predictive value calculated for CIN 2 or worse were 100% (95% CI = 91.4%-100.0%) and 100% (95% CI = 94.2%-100.0%), respectively. Specificity and positive predictive value among these subjects were 20.3% (95% CI = 16.1%-25.1%) and 14.4% (95% CI = 10.8%-18.9%), respectively.
Detection of HR-HPV in women with LSIL or higher-grade cytology using the HPV HR test may allow clinicians to further triage women for advanced clinical management.
高危型人乳头瘤病毒(HR-HPV)持续性被认为是宫颈癌发展的必要条件。由于并非所有低度鳞状上皮内病变(LSIL)或高级别鳞状上皮内病变的病例都与 HR-HPV 相关,因此检测这些宫颈异常女性中的 HR-HPV 可能对管理具有临床意义。本研究旨在检测 LSIL 或高级别细胞学病例中的 HR-HPV。
在一项多中心前瞻性临床研究中,分析了 3966 名美国女性的剩余液基细胞学标本。LSIL 或高级别细胞学病例的女性根据临床指征行阴道镜检查和宫颈活检。该试验用于检测经中央审查小组组织学证实为宫颈上皮内瘤变 2 级(CIN 2 级)或更高级别(CIN 2 级)的细胞学诊断为 LSIL 或更高级别病例中的 HR-HPV。
在 LSIL 或高级别细胞学且具有完整数据集的受试者中,11.8%(41/347)被诊断为 CIN 2 级或更高级别;82.1%(285/347)为 HR-HPV 阳性。在 HR-HPV 阳性的受试者中,CIN 2 级或更高级别和 CIN 3 级或更高级别的患病率分别为 14.4%(41/285)和 7.0%(20/285)。所有诊断为 CIN 2 级或更高级别(41/41)和 CIN 3 级或更高级别(20/20)的受试者均检测出 HR-HPV 阳性。CIN 2 级或更高级别的检测敏感性和阴性预测值分别为 100%(95%CI=91.4%-100.0%)和 100%(95%CI=94.2%-100.0%)。在这些受试者中,特异性和阳性预测值分别为 20.3%(95%CI=16.1%-25.1%)和 14.4%(95%CI=10.8%-18.9%)。
使用 HPV HR 试验检测 LSIL 或高级别细胞学病例中的 HR-HPV,可能有助于临床医生进一步对高级别临床管理进行分类。
