Risks of transplantation

A bone marrow, peripheral blood stem cell or umbilical cord blood transplantation is a medical procedure, and no procedure is risk-free. Patients should always consult their transplant physician about the associated risks. Outcomes have improved considerably thanks to collaboration between scientists, clinicians and nurses within scientific communities that collect data on procedures and analyse outcomes. Disease-free survival rates depend on various aspects, including disease stage and degree of HLA matching between donor and patient.
