RESUMO
Cervical cancer is a preventable disease. Nevertheless, stagnation has been seen in incidence rates also in countries with well-functioning healthcare. On this basis, we investigated associations between control interventions and changes in cervical cancer incidence in Denmark from 2009 to 2022. Data on human papillomavirus (HPV)-vaccination were retrieved from Staten's Serum Institute; on screening recommendations from Danish Health Authority, on screening performance from Danish Quality Database for Cervical Screening; and on cervical cancer incidence from Nordcan and Danish Cancer Register. We reported coverage with HPV vaccination (1+ dose); coverage with cervical cell samples; number of women with primary HPV tests; proportion of non-normal cell samples without timely follow-up; number of conizations; and cervical cancer incidence rates. In 2022, all women aged ≤29 had been offered childhood HPV vaccination with coverage of 80%-90%. By 2020-2022, the cervical cancer incidence rate in women aged 20-29 was 3 per 100,000; at level of disease elimination. In 2017, women aged 70+ were offered a one-time HPV screening, and by 2020-2022, the old-age peak in cervical cancer incidence had largely disappeared. From 2009 to 2022, proportion of non-normal cell samples without timely follow-up decreased from 20% to 10%, and conventional cytology was largely replaced by SurePath liquid-based cytology; these factors could explain the steady decrease in cervical cancer incidence rate. Implementation of primary HPV screening in women aged 30-59 in 2021 was reflected in a, probably temporary, increase in the 2022 cervical cancer incidence rate. In conclusion, combined interventions with childhood HPV vaccination; one-time HPV screening of elderly women; and better management of screening broke previous stagnation in cervical cancer incidence rate.
RESUMO
INTRODUCTION: Up to 39% of women in Denmark do not participate regularly in the cervical cancer screening program and initiatives to increase participation are called upon. The primary aim of this study was to describe previous screening history and characteristics of women attending screening in a walk-in clinic. Furthermore, we wanted to investigate barriers to cervical cancer screening. MATERIAL AND METHODS: We designed a walk-in clinic that was open 2 days a week from 16.00 to 19.00 h, located in the Departments of Gynecology in the two main hospitals of the North Denmark Region. The main purpose of the clinic was cervical cancer screening and the study period was 5 months. Women who were not eligible for screening or had other health complaints were referred to their general practitioner. The women included in the study, filled out a questionnaire regarding educational and occupational status; their screening history was registered using data from the Danish Pathology Register. RESULTS: During the study period, 255 women visited the walk-in clinic. The final study population consisted of 249 women who met the inclusion criteria. Age range of participants was 23-77 years, with a median age of 45 years. The majority of the participants were currently employed (81%) or students (10%), the remaining being retired (5%) or unemployed (4%). Screening history showed that 138 (55.4%) of the women were on time for the screening or delayed less than 6 months compared to their recommended screening interval. Sixty-one women (24.5%) were delayed >6 months but <2 years. Fifty women (20.1%) were classified as non-attenders, with more than a 2-year delay in their screening. In the group of non-attenders, eight women had never been screened. Of the remaining 42 women, the median time since last screening was 8.2 years (range 5.0-25.3 years). CONCLUSIONS: Women attending the walk-in clinic tended to be primarily actively working or students (91%). All age groups in the screening population were represented. Screening history showed that 44.6% had not followed the recommended screening program.
