increasing access to fertility preservation for women with breast cancer

Conditions: Breast Cancer

Summary: the evapref project aims to increase access to fertility preservation by developing an approach to improve and evaluate existing information and coordination tools developed by the pays-de-la-loire and occitanie regional cancer networks. first, the investigators will use a qualitative, iterative, user-centered and participatory approach to improve the current tools and create training content for the physicians who will use these tools. second, the investigators will conduct a randomized stepped wedge trial of women under 40 newly treated with chemotherapy for breast cancer. the investigators will evaluate the rate of fertility preservation consultation before and after implementation of the improved tools, over a 30-month period from mid-2023 to the end of 2025. finally, in a third step, the investigators will study their approach (context-sensitive implementation analysis) and provide key elements for its transferability to other contexts and in particular to other regional cancer networks in france.

background: with the increase in the number of long-term survivors, interest is shifting from cancer survival to life and quality of life after cancer. these include consequences of long-term side effects of treatment, such as gonadotoxicity. fertility preservation is becoming increasingly important in cancer management. international recommendations agree on the need to inform patients prior to treatments about the risk of fertility impairment and refer them to specialized centers to discuss fertility preservation. however, the literature reveals suboptimal access to fertility preservation on an international scale, and particularly in france, making information for patients and oncologists a potential lever for action. the overall goal is to improve access to fertility preservation and related consultations for women with breast cancer through the development and evaluation of a combined intervention targeting the diffusion of information for these patients and brief training for oncologists. methods: first, the investigators will use a qualitative, iterative, user-centered and participatory approach to improve existing information tools and create training content for oncologists (aim 1). second, the investigators will conduct a randomized stepped-wedge trial evaluating rate of fertility preservation consultation over a 30-month period (aim 2). the investigators will include 750 women aged 18 to 40 newly treated with chemotherapy for breast cancer at one of 6 participating centers. the primary outcome will be rate of fertility preservation consultation before and after using the combined intervention (informational brochure for patients and brief training for oncologists) and will be analyzed using linear regression models.third, the investigators will analyze their approach (context-sensitive implementation analysis) and provide key elements for transferability to other contexts in france (aim 3). discussion: after transitioning to the combined intervention, the investigators will expect to observe an increase in access to fertility preservation consultation. particular attention will be paid to the effect of this intervention on socially disadvantaged women, who are known to be at greater risk of inappropriate treatment. in addition, the user-centric design principles and participatory approaches used to optimize the acceptability, usability and feasibility of the combined intervention will likely enhance its impact, diffusion and sustainability.

Eligibility criteria:
inclusion criteria: * patients over 18 and under 40 years of age treated for newly diagnosed breast cancer and receiving chemotherapy. * people who are able to read the study information poster and the fertility preservation information brochure in french, either alone or with help from a caregiver or relative or an interpreter. * people with intellectual disability will be included as long as they are able able to read the study information poster and the fertility preservation information brochure in french alone or with help from a caregiver or relative or an interpreter.. exclusion criteria: * people whose mental health status precludes participation in the study, as determined by the clinical team.
