Researchers are conducting a large-scale national study in France involving children who were treated for solid tumors before 2000 and before age 19. The study aims to improve understanding of long-term effects caused by cancer and its treatments, including adverse health and social outcomes. The main goal is to estimate risks of such outcomes and help prevent them by providing tailored follow-up care, with the cohort being followed for up to 20 years from 2011. The study collects detailed information from medical records to assess radiation and chemotherapy doses received, vital status and causes of death from national registries, self-reported questionnaires covering social status and quality of life, and health insurance data on medical expenditures. Prior research within the cohort has identified increased risks of second cancers, cardiovascular diseases, thyroid issues, and other long-term effects linked to cancer treatments received during childhood. Participants are involved through data collection from multiple sources including medical records, national registries, questionnaires, and health insurance databases. Researchers monitor health events of interest related to the original cancer diagnosis and treatment exposures. The study measures outcomes like second malignancies, mortality compared to the general population, and various health and social consequences. This comprehensive approach supports improved understanding and care for childhood cancer survivors.
