Inclusion criteria

Inclusion criteria: 1. Women invited for the cervical cancer screening program (ages 30 - 60 years) 2. Residing in either the region covered by district health authority Amstelland-de Meerlanden and Zuid-Kennemerland

Exclusion criteria

Exclusion criteria: 1. Not called for screening, ie ages under 30 years, or over 60 years 2. Follow-up of previous non-normal cytology within the current screening round of the program, i.e., abnormal cytology or CIN lesions less than two years before inclusion 3. Status after extirpation of the uterus or amputation of the portio

Design outcomes

Primary

MeasureTime frame
The primary outcome measure of POBASCAM trial is the occurrence of histologically confirmed CIN3 lesions or (micro-) invasive carcinoma of the cervix found during the time span from intake up to and including the next screening round, i.e., in five years. Since women with normal cytology at the next screening round will not be referred for colposcopically-directed biopsies and therefore will not have a histological endpoint, it will be assumed that no precursor lesions of cervical cancer are present. This policy complies with regular cervical screening in The Netherlands.

Secondary

MeasureTime frame
As a secondary outcome measure, histologically confirmed cervical intraepithelial neoplasia grade 2 will also be investigated, since current guidelines recommend ablative treatment for these lesions as well. Other secondary parameters obtained include progression and regression of cytology diagnoses, clearance and acquisition of hrHPV infections and the number of referrals for colposcopically-directed biopsies.
