Primary HPV-testing has been shown to provide a superior detection of women at risk of cervical (pre)cancer compared to cytology-based screening. However, as most high-risk HPV infections are harmless, additional triage testing of HPV-positive women is necessary to identify those with cervical (pre)cancer. In this paper, we compare the performance, advantages and limitations of clinically relevant available triage strategies for HPV-positive women.
Many different colposcopy triage strategies, comprising both microscopy-based and molecular (virus/host-related) markers, have been suggested: Pap cytology, p16/Ki-67 dual-stained cytology, HPV16/18 genotyping, viral DNA methylation and host cell DNA methylation. Literature search was limited to triage strategies that have achieved at least phase 2 of the five-phase framework for biomarker development and studies including large cohorts (≥100 hrHPV-positive women). Triage markers were stratified by sample type (cervical scrape, self-collected sample) and by study population (screening, non-attendee, referral). Expert commentary: At present, repeat Pap cytology and Pap cytology combined with HPV16/18 genotyping are the only triage strategies that have been robustly shown to be ready for implementation. Other strategies such as p16/Ki-67 dual-stained cytology and host cell DNA methylation analysis, with or without additional HPV16/18 genotyping, are attractive options for the near future.
与基于细胞学的筛查相比,HPV 初筛已被证实可更有效地检测出有宫颈癌(前)风险的女性。然而,由于大多数高危 HPV 感染是无害的,因此需要对 HPV 阳性女性进行额外的分流检测,以识别出患有宫颈癌(前)的患者。本文比较了目前临床上相关的 HPV 阳性女性分流策略的性能、优势和局限性。
已经提出了许多不同的阴道镜检查分流策略,包括基于显微镜的和分子(病毒/宿主相关)标志物:巴氏细胞学、p16/Ki-67 双重染色细胞学、HPV16/18 基因分型、病毒 DNA 甲基化和宿主细胞 DNA 甲基化。文献检索仅限于至少达到生物标志物开发五阶段框架的第 2 阶段的分流策略,且研究纳入了大样本量(≥100 例 HPV 阳性女性)。根据样本类型(宫颈刮片、自我采集样本)和研究人群(筛查、未就诊、转诊)对分流标志物进行分层。
目前,重复巴氏细胞学检查和巴氏细胞学检查联合 HPV16/18 基因分型是仅有的两种已被证实可立即实施的分流策略。其他策略,如 p16/Ki-67 双重染色细胞学和宿主细胞 DNA 甲基化分析,无论是否联合 HPV16/18 基因分型,都是近期内很有吸引力的选择。
