摘要
Here, we describe a case of primary graft failure with severe sepsis in a boy who experienced frequent relapses of osteosarcoma. The patient had undergone haploidentical bone marrow transplant after engraftment of unrelated cord blood transplant performed 10 months earlier. Considering his severe condition, we transfused autologous peripheral stem cells along with a single dose of etoposide (50 mg/m(2)). Granulocyte engraftment was confirmed on human leukocyte antigen-microsatellite analysis of bone marrow on day 14. Although the patient died due to respiratory failure, transfusion of autologous hematopoietic stem cells is a reasonable rescue option for graft failure even in patients whose background hematopoiesis is reconstituted by a first donor.
