Brief Summary
In Denmark, the first birth cohorts of women offered HPV-vaccination as girls are entering the cervical screening program. These women are expected to be better protected against cervical cancer. It has not yet been decided how to screen these women. This method study will investigate a possible screening scheme that could provide a reduced burden of screening for HPV-vaccinated birth cohorts.

Outcome Measures
Primary Outcomes (1)
Cumulative CIN3+ (cervical intraepithelial neoplasia grade 3 and above) in baseline screen-negative women.
Histologically proven CIN3+ is chosen as primary outcome measure because it is the diagnostic threshold above which conization is recommended by the Danish Society of Gynecology and Obstetrics. Primary outcome will be based on intention-to-treat and per protocol analysis and stratified by region of residence. Primary HPV-testing with cytology triage every six years compared to cytology every three years will be approximated from the observed data.
After up to 9 years follow-up (end-of-study)
Secondary Outcomes (5)
Cumulative CIN3+ overall
After up to 9 years follow-up (end-of-study)
Cumulative CIN2 (cervical intraepithelial neoplasia grade 2) overall
After up to 9 years follow-up (end-of-study)
Cumulative CIN2 in baseline screen-negative women
After up to 9 years follow-up (end-of-study)
Cumulative CIN1 (cervical intraepithelial neoplasia grade 1) overall
After up to 9 years follow-up (end-of-study)
Cumulative CIN1 in baseline screen-negative women
After up to 9 years follow-up (end-of-study)
Other Outcomes (6)
Baseline CIN1
After up to 2 years follow-up
Baseline CIN2
After up to 2 years follow-up

Study Arms (2)
HPV-test
OTHERCobas HPV-DNA test is performed on the cervical sample in addition to the routine cytology
Routine
NO INTERVENTIONScreening with cytology as usual in the cervical screening program
Interventions
Cobas HPV-DNA testing device from Roche is already in standard use in the Danish screening program for purpose of triage and primary screening of women 60+. It has four signals; HPV-negative, HPV-16, HPV-18 and "other"
