Abstract: | Twelve patients with acute leukemia (7 with nonlymphoblasticleukemia and 5 with lymphoblastic leukemia) were treated withhigh-dose cyclophosphamide and 1,000 rad total body irradiationfollowed by allogeneic bone marrow transplantation from theirHLA-identical sibling donors. Of eight patients given transplantsat relapse, only one patient has become a long-term survivor;he is alive in disease-free complete remission (CR) 4 yr afterthe transplantation. A cure is probable in this patient. Offour patients given transplants during remission, two have survivedin unmaintained CR for almost 1 yr or more. Recurrent leukemiawas observed in two patients whose disease was resistant toconventional therapy at the time of transplantation. Major causesof treatment failure were interstitial pneumonia, hepatic failuredue to veno-occlusive disease, severe infection and relapse.Transplantation-related complications were more frequent andserious in patients who received transplants at relapse thanin those receiving them during remission. The incidence of graft-versus-hostdisease was relatively high but the disease was neither primarynor leading cause of death. These preliminary but relativelyencouraging data suggest that transplantation during remissionmay reduce posttransplant morbidity and mortality. This approachwill contribute to producing long-term survival or cure in patientswith adult acute leukemia if a suitable donor is available. |
