Impact budgétaire de l'utilisation de l'autotest dans le cadre du programme national de dépistage du cancer du col de l'utérus

A nationwide screening program for cervical cancer (CC) was organized in 2018 as part of the 2014-2019 French cancer plan, with the objective of reducing CC incidence and mortality in France by reaching an 80 % coverage rate. As an alternative to pap smear, vaginal self-sampling (VSS) aimed at identifying high-risk HPV carriage could help to achieve this goal. The objective of the present study is to compare the respective budgetary impacts of several self-sampling strategies.A budget impact model was developed to compare non-use of self-sampling in CC screening to the 5-year costs of 5 VSS strategies viewed from an all-payer perspective. While the first strategy was based on mailing the VSS kit with a reminder to participate in the screening program, the second was based on accompanying the mailed kit with an invitation to participate. The third and fourth strategies were based on providing health professionals with the kit, and thereby offering self-sampling as an alternative to pap smears for women undergoing CC screening and having previously received the kits. Finally, the fifth strategy was based on self-sampling as the one and only CC screening modality. The parameters of the model were based on past screening participation data and experiments in France on organized screening and VSS use. The costs included those of procedures associated with screening and program organization.All in all, the costs associated with cervical cancer screening would represent approximately 1 billion euros over 5 years. All strategies would be associated with participation ranging from 81% to 84%, which would represent an increase of 4.7% to 5.2% of lesions diagnosed by screening and a cost reduction between €30M and €87M over 5 years, with the exception of the strategy based on sending the kit (with the reminder associated or not) to the health professionals offering this option (+€23M and +€6M).In conclusion, the use of self-sampling as an alternative to pap smears for non-participating women would increase participation, with only a moderate budgetary impact and could, in some cases, even induce savings.
