Hepatic veno-occlusive diseases (VOD) during cancer treatment in children are serious toxicities that have occurred with interruptions of chemotherapy and risk of relapse. In addition, these toxicities have a negative impact on the patient's quality of life, serious long-term sequelae and are potentially fatal in children. The risk factors associated with the occurrence of these complications are, to date, unknown, at the exception to the exposition to certain treatments (6-thioguanine, busulfan, actinomycin D, radiotherapy, etc.). To understand the effects of this toxicity and those of susceptibility to the disease becomes a major issue in the treatment of these children.
