    Abstract

    Background: Human papillomavirus (HPV) testing is increasingly used as the primary cervical cancer screening test. In a large pilot implementation, we compared participation, referrals and detection of high-grade cervical intraepithelial neoplasia (CIN) in HPV- versus cytology-based cervical cancer screening.

    Methods: The implementation was embedded into the routine screening program at Lillebaelt Hospital, Department of Pathology, Vejle, Denmark. Based on the area of residence, women aged 30-59 years were screened by either HPV testing (with HPV16/18 genotyping and cytology triage) or cytology (with HPV triage for minor abnormalities). Our analysis includes women invited or screened during May 2017-May 2018 (invited: n=35,081; screened: n=28,352) with 6 months of follow-up. Information on screening results and sociodemographic characteristics were obtained from registers. Using logistic regression, we estimated odds ratios (ORs) with 95% confidence intervals (CIs) of participation, referral and CIN3+-detection in HPV- versus cytology-based screening, adjusting for sociodemographic characteristics.

    Results: Participation was virtually identical in the HPV- and cytology group (58.4% vs 58.8%; ORadjusted=0.97, 95% CI, 0.93-1.01). Referral to colposcopy was more common in the HPV- than cytology group (3.8% vs 2.1%; ORadjusted=1.88, 95% CI, 1.63-2.17). More cases of CIN3+ were detected in the HPV- than cytology group (1.0% vs 0.7%, ORadjusted=1.47; 95% CI, 1.13-1.91).

    Conclusion: Participation did not differ between HPV- and cytology-based screening. HPV-based screening detected more cases of CIN3+, but in this initial screening round also led to more colposcopies than cytology-based screening.
