Administration of recombinant human granulocyte-macrophage colony-stimulating factor after autologous bone marrow transplantation in children with acute myelogenous leukemia: a note of caution.
A series of 22 consecutive pediatric patients undergoing ABMT for treatment of primary AML was reviewed in an efficacy analysis of recombinant human granulocytemacrophage colony-stimulating factor (rhGM-CSF). Treatment with at least two cycles of chemotherapy and a standard conditioning regimen of busulfan and cyclophosphamide preceded the marrow infusion. Twelve patients who underwent transplants between 1992 and 1994 received 5.5 micrograms/kg/day rhGM-CSF as part of their transplant protocol. They were compared with 10 patients who underwent transplants between 1989 and 1991 but did not receive rhGM-CSF. Despite containing a significantly higher proportion of patients in first clinical remission at the time of the transplant, the rhGM-CSF-treated group had a significantly higher relapse and poorer overall survival rate after ABMT than the untreated group (36 vs 90%). The rhGM-CSF-treated group tended to have more rapid neutrophil engraftment and shorter hospital stays; however, neither of these trends was statistically significant. To properly determine the role of rhGM-CSF in the survival of pediatric patients undergoing ABMT for treatment of AML, a prospective randomized trial is desirable. Until these data are available, the current analysis suggests that particular caution is indicated with the use of this drug in this group of patients.
