Self-sampling Among Long-term Non-attenders to Cervical Cancer Screening

A randomized control trial will be performed on the effect of vaginal HPV self‐sampling on screening attendance, targeting women age 35‐69 who have not attended screening for at least 10 years. The women will be randomly allocated to one of three interventions: (i) receive a reminder to be screened by a physician; (ii) receive a self‐sampling kit; (iii) receive an offer to order a self‐sampling kit. Comparisons of the screening attendance among the interventions will be made. To also address potential effects on inequities, the analyses will include comparisons by sociodemographic characteristics. The rates of cervical cancer/precancer among the interventions will also be compared. Further, to assess the feasibility of and the compliance to follow‐up after a positive HPV test in this population, half of the HPV‐positive women from each self‐sampling arm will be referred to initial follow‐up by their regular general practitioner (GP), while the other half will be referred to initial follow‐up by a gynecologist. The project will be embedded in the national cervical cancer screening program, and will utilize the extensive nationwide registers describing performance and outcomes of screening collected by the Cancer Registry of Norway.
