Abstract
Objective: This study aimed to investigate the triage value obtained in DNA ploidy analysis of cervical exfoliated cells in women with high-risk human papillomavirus (HR-HPV)-positive status in the primary screening of cervical cancer.
Methods: The authors selected 3,000 HR-HPV-positive women for cervical exfoliated cell sampling and conducted DNA ploidy analysis, liquid-based cytology (LBC), colposcopy, and cervical biopsy. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of high-grade squamous intraepithelial lesion (HSIL)-positive detection between DNA ploidy analysis and LBC were compared according to histopathology diagnosis as the golden criteria, and the efficacy of predicting HSIL-positive immediate risk was evaluated.
Results: A total of 2,892 HR-HPV-positive women were enrolled in the investigation. For HSIL+ women, the DNA ploidy group showed a significantly higher sensitivity (CIN2+: 79.21% vs 65.35%, p = .022; CIN3+: 81.48% vs 70.37%, p = .013), lower specificity (CIN2+: 85.00% vs 96.59%, p < .001; CIN3+: 84.14% vs 93.41%, p < .001), and lower PPV (CIN2+: 16.23% vs 29.33%, p = .001; CIN3+: 8.92% vs 16.89%, p = .002) compared with the LBC group, whereas the NPV showed no significant difference. Compared with LBC alone in diagnosing HSIL, DNA ploidy combined with LBC showed higher specificity (CIN2+: 99.21% vs 96.59%, p = .003; CIN3+: 96.48% vs 93.41%, p < .001) and higher PPV (CIN2+: 41.35% vs 29.33%, p = .022; CIN3+: 24.81% vs 16.89%, p = .028), whereas no significant difference was observed in the sensitivity (CIN2+: 54.46% vs 65.35%, p = .063; CIN3+: 61.11% vs 70.37%, p = .221) and NPV ( p > .05). Among the HR-HPV-positive women positive for DNA ploidy, the imminent risk of CIN2+ and CIN3+ were 15.62% and 8.92%, respectively, above the threshold for the colposcopy positive rate. Among the positive cases both for DNA ploidy and the LBC result of negative for intraepithelial lesion or malignancy, the immediate risk of CIN3+ was 3.31%, below the threshold for colposcopy positive rate. Besides, for women with LBC result of ASC-US and above, the immediate risk of CIN3+ was greater than 4%.
Conclusions: The DNA ploidy analysis can be used as an effective triage method for HR-HPV-positive women during the primary screening of cervical cancer, although it can provide higher specificity when combined with LBC and reduce the referral rate for colposcopy.
期刊介绍：
The Journal of Lower Genital Tract Disease is the source for the latest science about benign and malignant conditions of the cervix, vagina, vulva, and anus.
The Journal publishes peer-reviewed original research original research that addresses prevalence, causes, mechanisms, diagnosis, course, treatment, and prevention of lower genital tract disease. We publish clinical guidelines, position papers, cost-effectiveness analyses, narrative reviews, and systematic reviews, including meta-analyses. We also publish papers about research and reporting methods, opinions about controversial medical issues. Of particular note, we encourage material in any of the above mentioned categories that is related to improving patient care, avoiding medical errors, and comparative effectiveness research. We encourage publication of evidence-based guidelines, diagnostic and therapeutic algorithms, and decision aids. Original research and reviews may be sub-classified according to topic: cervix and HPV, vulva and vagina, perianal and anal, basic science, and education and learning.
The scope and readership of the journal extend to several disciplines: gynecology, internal medicine, family practice, dermatology, physical therapy, pathology, sociology, psychology, anthropology, sex therapy, and pharmacology. The Journal of Lower Genital Tract Disease highlights needs for future research, and enhances health care.
The Journal of Lower Genital Tract Disease is the official journal of the American Society for Colposcopy and Cervical Pathology, the International Society for the Study of Vulvovaginal Disease, and the International Federation of Cervical Pathology and Colposcopy, and sponsored by the Australian Society for Colposcopy and Cervical Pathology and the Society of Canadian Colposcopists.
