Researchers are studying the management and follow-up of non-muscle-invasive bladder cancer (NMIBC), a type of bladder tumor that affects the inner lining and underlying tissue but not the muscle layer. This cancer type accounts for a significant portion of bladder cancer cases in France, with many patients experiencing tumor recurrence within five years. The study aims to evaluate the diagnostic accuracy of urine biomarker tests compared to bladder endoscopy, which is the current standard for detecting tumor recurrence. Additionally, it will describe tumor characteristics, patient history, treatments, and regional differences in care. Patients being monitored for NMIBC and undergoing routine care will have their medical details, including prior treatments and urine test results, recorded in a registry. Follow-up includes regular bladder endoscopy exams, with dates and findings noted by urologists. Urine test results taken before biopsies will also be tracked. This observational study will analyze the performance of urine tests by calculating sensitivity, specificity, and predictive values, and exploring differences based on tumor grade, stage, and previous treatments. The goal is to include 8000 patients across France over six years. Participants will provide data through medical records and routine exams during their personalized care plans. Urine samples and bladder fibroscopy results will be collected at each follow-up visit to assess test accuracy over a five-year period. Researchers will monitor recurrence-free survival and urine test performance, aiming to identify if urine tests can safely reduce the need for invasive cystoscopy. The study focuses on long-term monitoring to better understand and improve care for NMIBC patients.

Researchers are studying the long-term health outcomes of people living with HIV who are treated with antiretroviral therapy (ART). While ART has helped make HIV a chronic condition with survival rates close to the general population, those living with HIV still face higher risks of other health problems, including immune system issues, cardiovascular disease, cancer, and complications from aging. The study also looks at psychiatric, neurological, and social factors affecting these individuals, aiming to better understand overall health beyond just physical symptoms. Participants in this study receive follow-up care based on national guidelines, where demographic, clinical, biological, and treatment data are collected at each hospital visit using a standardized questionnaire. All health events are recorded according to the International Classification of Diseases (ICD-10). Additionally, a biobank of samples is collected from consenting participants at entry and every two years thereafter to support further research. People in the study will be monitored for up to four years, with annual assessments of socio-demographic characteristics and health status. The study tracks the development of new health problems, monitors the effectiveness and side effects of ART regimens, and gathers comprehensive data on participants’ clinical management. This long-term observation aims to provide a detailed understanding of morbidity and mortality risks in treated HIV patients.
