Background: Regular participation in cervical cancer screening is critical to reducing mortality. Although certain sociodemographic factors are known to be associated with one-time participation in screening, little is known about other factors that could be related to regular participation. Therefore, this study evaluated the association between health-related behavioral factors and regular participation in cervical cancer screening. Methods: The Lifelines population-based cohort was linked to data for cervical cancer screening from the Dutch Nationwide Pathology Databank. We included women eligible for all four screening rounds between 2000 and 2019, classifying them as regular (4 attendances), irregular (1–3 attendances), and never participants. Multinomial logistic regression was performed to evaluate the association between behavioral factors and participation regularity, with adjustment made for sociodemographic factors. Results: Of the 48,325 included women, 55.9%, 35.1%, and 9% were regular, irregular, and never screening participants. After adjustment for sociodemographic factors, the likelihood of irregular or never screening participation was increased by smoking, obesity, marginal or inadequate sleep duration, alcohol consumption and low physical activity, while it was decreased by hormonal contraception use. Conclusion: An association exists between unhealthy behavioral factors and never or irregular participation in cervical cancer screening.
Background: Molecular triage testing for high-risk human papillomavirus (hrHPV)-based cervical cancer screening can be used in self-sampling, potentially reducing unnecessary colposcopies and increasing attendance. However, its commercial value remains underexplored. This study used headroom analysis to estimate the maximum reimbursable price (MRP) at which molecular testing would be cost-effective for the triage of hrHPV-positive women, compared with cytology. Methods: A validated microsimulation Markov model for the Dutch cervical cancer screening program evaluated three triage scenarios: (1) cytology (base scenario), (2) molecular testing in self-samples only (scenario I), and (3) molecular testing on self- and GP-collected samples (scenario II). Test sensitivity and specificity ranged from 65% to 95%, with a threshold of EUR 20,000 per life-year gained. Results: In scenario I, MRPs ranged from EUR 244 (85% sensitivity, 75% specificity) to EUR 435 (95% sensitivity, 95% specificity). In scenario II, molecular testing was cost-effective across all parameters, with MRPs from EUR 162 (65% sensitivity, 65% specificity) to EUR 624 (95% sensitivity, 95% specificity). Increasing the sensitivity did not significantly affect life-years gained (due to the low mortality of cervical cancer in the Netherlands), but increased specificity did reduce the number of unnecessary colposcopies. Conclusions: Enhancing the specificity of molecular triage testing will improve its commercial value by reducing colposcopy referrals without affecting the number of life-years gained.
Purpose: To our knowledge, there are very few studies evaluating if the levels of folate modify the risk of cervical intraepithelial neoplasia grade 2 and higher (CIN2+ and CIN3+) associated with the levels of HPV genome methylation, two cofactors related to single carbon metabolism and independently associated with cervical cancer in previous studies. We conducted a case–control study nested in a three-arm randomized clinical pragmatic trial (ASCUS-COL trial) to evaluate the risk of CIN3+ associated with methylation levels according to serum folate concentrations. Methods: Cases (n = 155) were women with histologically confirmed CIN2+ (113 CIN2, 38 CIN3, and 4 SCC) and controls were age and follow-up time at diagnosis-matched women with histologically confirmed ≤ CIN1 (n = 155), selected from the 1122 hrHPV + women of this trial. The concentrations of serum folate were determined by the radioimmunoassay SimulTRAC-SNB-VitaminB12/Folate-RIAKit and the methylation levels by the S5 classifier. Stepwise logistic regression models were used to estimate the association between folate or methylation levels and CIN2+ or CIN3+. The joint effect of folate levels and methylation on the risk of CIN3+ was estimated using combinations of categorical stratifications. Results: Folate levels were significantly lower in women with CIN3+ than in other diagnostic groups (p = 0.019). The risk of CIN3+ was eight times higher (OR 8.9, 95% CI 3.4–24.9) in women with folate deficiency and high methylation levels than in women with normal folate and high methylation levels (OR 1.4, 95% CI 0.4–4.6). Conclusion: High methylation and deficient folate independently increased the risk of CIN3+ while deficient folate combined with high methylation was associated with a substantially elevated risk of CIN3+.
Research has long since confirmed the benefits of regular cervical cancer screening (CCS) worldwide. However, some developed countries have low participation rates despite well-organized screening programs. Given that studies in Europe typically define participation in 12-month windows from an invitation, we evaluated both whether extending this defined time window could reveal the true participation rate and how sociodemographic determinants affect participation delays. This involved linking data from the Lifelines population-based cohort with CCS-related data from the Dutch Nationwide Pathology Databank and including data for 69 185 women eligible for screening in the Dutch CCS program between 2014 and 2018. We then estimated and compared the participation rates for 15- and 36-month time windows and categorized women by the primary screening window into timely participation (within 15 months) and delayed participation (within 15-36 months) groups, before performing multivariable logistic regression to evaluate the association between delayed participation and the sociodemographic determinants. Participation rates for the 15- and 36-month windows were 71.1% and 77.0%, respectively, with participation considered timely in 49 224 cases and delayed in 4047 cases. Delayed participation was associated with age 30-35 years (odds ratio [OR]: 2.88, 95 %CI: 2.67-3.11), higher education (OR: 1.50, 95 %CI: 1.35-1.67), the high-risk human papillomavirus test-based program (OR: 1.67, 95 %CI: 1.56-1.79), and pregnancy (OR: 4.61, 95 %CI: 3.88-5.48). These findings show that a 36-month window for monitoring attendance at CCS better reflects the actual participation rate by accommodating possible delayed uptake among younger, pregnant, and highly educated women.

Cervical cancer remains a significant public health issue, ranking as the fourth most common cancer in women globally. In the Netherlands, cervical cancer incidence declined steadily from 1989 to 2001 but increased between 2001 and 2007. This study updates trends in cervical cancer incidence from 1989 to 2023 in the Netherlands and evaluates the impact of screening practices and participation rates in the national population‐based screening program. This ecological study uses group‐level data from the Netherlands Cancer Registry (1989–2023) to analyze trends across three temporal dimensions—age, period, and cohort—using age–period–cohort analysis and join‐point regression to identify significant changes in trends over time. Cervical cancer incidence declined steadily from 1989 to 2003 but increased from 2003 to 2023, particularly among younger birth cohorts (1976–1995). This increase aligns with the decline in screening participation, which dropped from over 77% before 2003 to below 60% in subsequent years, as well as the introduction of primary high‐risk human papillomavirus testing in 2017, which has higher sensitivity than cytology, leading to more cases being detected and, consequently, an increase in incidence. Trends in cervical cancer incidence in the Netherlands indicate a positive impact of the screening program, with a steady decline over the years. However, efforts should focus on increasing participation in both screening and vaccination, as this is crucial for achieving the goal of reducing incidence to below 4 per 100,000 women, in line with the global strategy to eliminate cervical cancer.
Introduction. Low-cost, accurate high-risk HPV tests are needed for cervical cancer screening in limited-resource settings.Objective. To compare the performance of the low-cost Hybribio-H13 test with the Hybrid Capture® 2 to detect cervical intraepithelial neoplasia grade 2 or 3 (CIN2 and CIN3).Materials and methods. Archived baseline samples tested by the Hybrid Capture® 2 from women of the ASCUS-COL trial, aged 20 to 69 years, with biopsy-colposcopy directed diagnosis of CIN2+ (n = 143), CIN3+ (n = 51), and < CIN2 (n = 632) were blindly tested by the Hybribio-H13 test.Results. The relative sensitivity of the Hybribio-H13 test versus the Hybrid Capture® 2 for detecting CIN2+ was 0.89 (90% CI = 0,80-0,98; NIT = 0,66), and for CIN3+ was 0,92 (90% CI = 0,85-0,98; NIT = 0,35). Relative specificity was 1.19 (90% CI = 1.05-1.33; NIT <0.00001). In the analysis restricted to women older than 30 years, the relative sensitivity of the Hybribio-H13 for CIN3+ was marginally below unity (ratio = 0.97; 90% CI = 0.95-0.99), and the specificity remained higher than the Hybrid Capture® 2 test.Conclusion. The Hybribio-H13 test was as specific as the Hybrid Capture® 2 for detecting CIN2+ or CIN3+ but less sensitive. Considering these results and the young age of the population recruited for screening because of ASCUS cytology, we suggest our results warrant the evaluation of the Hybribio-H13 for screening cervical cancer, especially in the evaluated population.
