In February 1986 we transplanted a 10-year-old girl with AML in second remission with the bone marrow of an unrelated donor. HLA-types were different for one A- and one B-antigen between patient and donor. Conditioning regimen consisted of 14 Gy total body irradiation with lung shielding, 8 X 3 g/m2 cytosin arabinoside and 90 mg/kg cyclophosphamide. GVHD-prophylaxis was performed with cyclosporin A, methotrexate and prednisolone. Only mild GVHD I of the skin could be observed after rapid engraftment. 100 days after transplantation the patient was in good clinical condition and GVHD-prophylaxis was discontinued without any reactivation of acute or chronic GVHD. Engraftment was documented by sex chromosome and blood group typing. 120 days after transplantation leukemic blasts were detected in the peripheral blood and the child died 130 days after BMT from relapse of the leukemia. Despite the negative outcome, this was the first successful bone marrow transplantation from a unrelated donor in Germany.
