Ethical problems in bone marrow transplantation in children.
The medical staff caring for children with hematological or oncological diseases is often faced with delicate ethical and, at times, legal problems. Although many of these are common to other branches of pediatrics where patients are children lacking decision-making capacity, others, such as bone marrow transplantation (BMT), are peculiar to this specialty. This is a vanguard treatment for a wide range of diseases that are either incurable or resistant to conventional therapies. If the patient does not have a related donor, ethical and legal problems can occur: profound emotional dilemmas arise both because of the fretful search for a donor and because of the limited period the patient can be transplanted with good expectations of success. National and International Registries are linked to all BMT Units for the identification of compatible donors with the recipient. Hospitals hosting a BMT Unit must fulfill several requirements which are crucial to guaranteeing the best results when faced with the complexity and aggressiveness of transplantation and possible complications, such as a blood bank, an infectious diseases department, a rehabilitation unit, the availability of consultants, as well as playworkers, teachers, psychologists and social workers. Any trial carried out in a Center without sufficient experience, simply pleading the concept of "last hope" is not ethical, even considering possible late effects and sequelae. For allogeneic bone marrow transplantation it is necessary to obtain both the Consent of the donor and the Consent of parents of the recipient. Often the donor is a child sibling of the patient, lacking decision-making capacity as well. Information to parents of both children must be detailed. In reality, there are practically no risks for the child donor and, if any, they are linked to the general anaesthesia. The text of the Informed Consent is usually deliberated and accepted in advance by the Ethics Committee of the Institution where the patient is followed. Voluntary donor's Consent is required at different steps: at the entry in the Registry, when typing of major histocompatibility complex, at bone marrow harvesting under general anaesthesia. In Italy, Article No. 3, Law No. 107 of May 4, 1990 allows parents or legal guardians to consent to the bone marrow donation of a minor.
