Pharmacogenetic Study of Antimitotic Therapies Involved in Hepatic VOD in Children With Nephroblastoma or ALL

Case-control study, nested in two French multicenter cohorts, on pharmacognenetic, biological and clinical susceptibility factors associated with the occurrence of hepatic veno-occlusive disease during the anticancer treatment for nephroblastoma or acute lymphoblastic leukemia, with centralized genetic analysis. After obtaining consent (patient or parents for minor patients), a blood sample is collected during the routine follow-up consultation and tubes are sent directly to Paris for the pharmacogenetic analysis at the end of the study.
