Marrow transplantation for children with acute nonlymphoblastic leukemia in first remission

Thirteen children between the ages of two and 17 years with acute nonlymphoblastic leukemia in first remission were transplanted from HLA matched sibling donors. They were transplanted at a median of four months [2-8] following diagnosis. The preparative regimen of cyclophosphamide and total body irradiation was well tolerated. Two patients died of pneumonia 66 and 94 days following transplant. One patient relapsed at 431 days, and died of leukemia at 490 days. Ten are living in remission 20-53 months following transplantation. None are on maintenance chemotherapy, and all lead normal lives. As yet, growth is not impaired.
