Clinical study - Recherches "plusieurs pathologies"

Multi-cohort exploratory prospective study. Participation in the ALCINA 4 study does not change the standard management of the patient, including the treatments administered. A sampling schedule will be set up for each cohort.;Depending on the clinical context studied and the biomarkers studied and/or sought, the timing of blood samples will vary between cohorts. There may be up to 4 samples taken per patient for up to 12 or 18 months. If a specific tumor sample is required, it will be collected only once during the Study.
