Successful treatment of refractory Langerhans cell histiocytosis with pulmonary aspergillosis by reduced-intensity conditioning cord blood transplantation.
The prognosis of multisystem LCH in children with risk organ involvement is extremely poor when they fail to respond to conventional chemotherapy. In such patients, allogeneic SCT may produce complete and sustained remission; however, high-dose myeloablative regimens are frequently associated with treatment-related morbidity and mortality. More recently, allogeneic SCT following an RIC regimen has been performed as an alternative salvage approach. We describe a nine-month-old boy with refractory multisystem LCH with pulmonary aspergillosis who was successfully treated with reduced-intensity cord blood transplantation.
