Study Overview
Brief Summary
The cervical cancer screening coverage remains moderate (60%) in France. The aim of the study is to evaluate the efficacy of two experimental invitation strategies (offer of urine or vaginal self-sampling kits) to reach under-screened populations and compare them with the current invitation strategy in rural departments (low medical density and low participation rate) in France.
The study is a randomised controlled trial with three arms: a control arm (conventional invitation letter) and two experimental arms (mailing of a urine or vaginal self-sampling kit). The target population includes women aged 30-65 years, who had no screening test recorded since more than four years and who did not respond to an invitation letter within twelve months before. The primary outcome measure is the participation rate in each arm.
A team of psychologists will also investigate attitudes and experiences by semi-structured/focus-group interviews with voluntary CapU4 participants and with health professionals.
CapU4 will identify effective strategies to reach women not responding to current screening invitations and will generate information about acceptance of self-sampling among women and health professionals.
Detailed Description
Research question: does the offer of self-sampling kits result in higher attendance to cervical cancer screening compared to sending invitation letters which recommend women to contact a health professional for taking a cervical specimen?
Systematic reviews indicate that Human Papillomavirus (HPV) testing on vaginal specimens taken by the woman her-self is as accurate to detect cervical precancer as HPV testing of cervical specimens collected by a clinician, under the condition that a validated polymerase chain reaction (PCR)-based HPV assay is used. Similar results are shown from recent studies where HPV testing was performed on first-void urine collected with an appropriate device and transport medium. A recent meta-analysis of randomised trials showed higher response rates when under-screened women receive a self-sampling kit at home compared to traditional invitation or reminder letters. However, the absolute participation rates are highly variable among studies. Whereas qualitative research indicates that women prefer collection of urine rather than a vaginal self-sample, no data are available that the offer of urine kits would result in higher participation among women who do not participate regularly in cervical cancer screening.
Objectives:
- To evaluate the effectiveness of two experimental invitation strategies (urine or vaginal self-sampling) to reach under-screened populations and compare them to the current invitation strategy in rural departments in France.
- To improve the response rate among women aged 30 to 65 years (not screened over a period longer than the recommended screening interval) who did not respond to a conventional prior invitation.
