Brief summary
The primary objective of this clinical trial is to assess cervical cancer screening participation among under-screened women invited through organized breast cancer screening programs in Switzerland. This randomized trial will compare three arms: 1. Intervention group 1: Sensitization to Cervical Cancer (CC) screening Women will receive an awareness letter explaining the importance of cervical cancer screening, the Swiss recommendations and an invitation to schedule an appointment. 2. Intervention group 2: Home-based Human papillomavirus infection (HPV) self-sampling Women will receive a free-of-charge vaginal self-sampling kit for HPV infection 3. Observational control group Women selected in the control arm will only be recruited one year following the screening of those in the intervention arm (T0+1), as to not influence Cervical Cancer Screening (CCS) behavior during this period by being reminded of screening recommendations.
Detailed description
Secondary objectives are: * To identify and compare the association of socio-demographic characteristics with screening participation in all study arms (cf. 3.2 study design). * To compare the use of primary screening methods (HPV test vs. Papanicolaou test) between study arms. * To compare prevalence of positive primary screening and triage results between study arms. * To compare follow-up rates for participants screened positive in both intervention arms. * To evaluate acceptability of both screening strategies (sensitization vs. home-based). * To assess the relationship between CCS behavior and Breast Cancer Screening (BCS) behavior.
Interventions
Women will receive an awareness letter explaining the importance of cervical cancer screening, the Swiss recommendations and an invitation to schedule an appointment.
Women will receive a free-of-charge vaginal self-sampling kit for HPV infection.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Participation to Cervical Cancer Screening (CCS) | 12 months | Participation to Cervical Cancer Screening (CCS) (primary HPV test or cytology) in the past 12 months, self-declared, proportion in % |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Choice of primary screening methods (HPV testing vs cytology) | 12 months | Difference between study arms of the proportion of participants screened by HPV test versus cytology in each arm. |
| Prevalence of positive primary screening (HPS test) and triage results (cytology) | 12 months | Difference between study arms of the: * Prevalence of screen-positive women (i.e. HPV-positive or Atypical squamous cells of undetermined significance - ASC-US+) * Proportion (%) of HPV-positive women with ASC-US+ upon triage * Proportion (%) of Cervical Intraepithelial Neoplasia Grade 2 (CIN2+) diagnosed * Proportion (%) of Cervical Cancer (CC) diagnosed * Proportion (%) of participants treated for CIN2+ or CC |
| Follow-up rates for participants screened positive | 12 months | Difference between study arms of the proportion (%) of primary screen-positive women who have undergone triage |
| Correlation of socio-demographic characteristics with screening participation | 12 months | Regression coefficients of screening in the past 12 months for: education level, occupation, relationship status, sexual orientation, mother tongue, country of origin, residential area, children, follow-up by general practitioner or gynecologist, age, number of years living in Switzerland, Body Mass Index (calculated based on weight and height). Measurement tool: self-reported from questionnaire |
| Reasons for non-compliance | 12 months | Proportion (%) of participants among unscreened women indicating predefined reasons for non-compliance |
| Association between Cervical Cancer Screening (CCS) behavior and Breast Cancer Screening (BCS) screening behaviors | 12 months | Difference in the study arms: of the proportion (%) of participants having done all screenings, and participants having selected only one or two screenings, and participants having done none. |
| Acceptability of screening strategies | 12 months | Difference between study arms of the: \- Mean satisfaction score (Likert scale, from 1 Totalement satisfied to 4 Very unsatisfied) |
