Primary screening for high-risk human papillomavirus (hrHPV) with cytological triage for women with non-16/18 hrHPV-positive status has become popular in China. However, cytology relies on the subjective judgment of pathologists, leading to inconsistent clinical performance.
A total of 657 hrHPV-positive women aged 25-64 years were enrolled in this cross-sectional study. All participants underwent colposcopic biopsy after cytology triage, with cytology residual specimens undergoing DNA methylation testing. CIN2+ and CIN3+ sensitivity and specificity were compared between the different triage strategies (n=487): PAX1 methylation (PAX1) , Glycophorin C methylation (GYPC), cytology, and combinations between them or with HPV16/18.
The area under the receiver operating characteristic curves (AUCs) for PAX1 and GYPC in detecting CIN2 or worse (CIN2+) were 0.867 (95% confidence interval [CI]: 0.796-0.937) and 0.873 (95% CI: 0.808-0.938), respectively. The sensitivities of PAX1 and GYPC were consistent with those of cytology for both CIN2+ and CIN3+ detection. The relative specificities of PAX1 and GYPC for CIN2+ detection compared to cytology were 2.83 (95% CI: 2.33-2.45) and 3.09 (95% CI: 2.40-3.98), respectively. The relative specificities of combining HPV 16/18 with PAX1 and GYPC for CIN2+ detection compared to cytology were 3.38 (95% CI: 2.96-3.86) and 3.67 (95% CI: 3.15-4.27), respectively. Compared to low levels of DNA methylation, high levels of PAX1 and GYPC resulted in odd ratios (ORs) of 57.66 (95% CI: 13.57-409.12, p < 0.001) and 23.87 (95% CI: 6.49-115.42, p < 0.001) for CIN3+, adjusted for HPV 16/18 and cytology results.
PAX1 and GYPC demonstrated superior ability to identify cervical precancerous lesions and cervical cancer, with AUC values exceeding 0.85. For detecting CIN2+/CIN3+ in women with hrHPV-positive status, DNA methylation (combined with HPV 16/18) showed higher specificity than cytology (combined with HPV 16/18) and is a potential molecular biomarker for detecting cervical (pre)cancer.
在中国,对非 16/18 高危型人乳头瘤病毒(hrHPV)阳性状态的女性进行 hrHPV 初筛联合细胞学分流已得到广泛应用。然而,细胞学依赖于病理学家的主观判断,导致其临床性能不一致。
本横断面研究共纳入 657 名年龄在 25-64 岁之间的 hrHPV 阳性女性。所有参与者均在细胞学分流后行阴道镜活检,细胞学剩余标本行 DNA 甲基化检测。比较不同分流策略(n=487)之间的 CIN2+和 CIN3+的灵敏度和特异性:PAX1 甲基化(PAX1)、血型糖蛋白 C 甲基化(GYPC)、细胞学,以及它们之间或与 HPV16/18 的组合:
PAX1 和 GYPC 检测 CIN2 或更高级别病变(CIN2+)的受试者工作特征曲线(ROC)下面积(AUC)分别为 0.867(95%置信区间 [CI]:0.796-0.937)和 0.873(95% CI:0.808-0.938)。PAX1 和 GYPC 的灵敏度与细胞学检测 CIN2+和 CIN3+的灵敏度一致。与细胞学相比,PAX1 和 GYPC 检测 CIN2+的相对特异性分别为 2.83(95% CI:2.33-2.45)和 3.09(95% CI:2.40-3.98)。与细胞学相比,HPV16/18 联合 PAX1 和 GYPC 检测 CIN2+的相对特异性分别为 3.38(95% CI:2.96-3.86)和 3.67(95% CI:3.15-4.27)。与低水平的 DNA 甲基化相比,高水平的 PAX1 和 GYPC 导致 CIN3+的比值比(OR)分别为 57.66(95% CI:13.57-409.12,p<0.001)和 23.87(95% CI:6.49-115.42,p<0.001),校正 HPV16/18 和细胞学结果后。
PAX1 和 GYPC 对识别宫颈癌前病变和宫颈癌具有较高的能力,AUC 值超过 0.85。对于检测 HPV16/18 阳性状态女性的 CIN2+/CIN3+,DNA 甲基化(联合 HPV16/18)比细胞学(联合 HPV16/18)具有更高的特异性,是一种潜在的宫颈癌(前)检测的分子生物标志物。
