Comparison of outcome of allogeneic bone marrow transplantation with and without granulocyte colony-stimulating factor (lenograstim) donor-marrow priming in patients with chronic myelogenous leukemia.

Abstract To investigate the effect of granulocyte colony-stimulating factor (G-CSF) donor-marrow priming on hematopoietic recovery and clinical outcome after allogeneic hematopoietic stem cell transplantation, we compared HILA-matched related marrow transplantation with and without G-CSF donor priming in a prospective randomized study for a homogeneous group of chronic myelogenous leukemia (CML) patients. Fifty patients (aged 12-41 years) with CML were enrolled in the study. Thirty-two patients (study group) received the marrow grafts primed with G-CSF at 3 to 4 micro/kg per day for 7 days prior to the marrow harvest, and 18 patients (control group) received the marrow grafts without G-CSF priming. All patients received the same graft-versus-host disease (GVHD) prophylaxis (cyclosporine A and methotrexate) and postgraft G-CSF treatment, 3 to 4 micro/kg daily until the absolute neutrophil counts (ANCs) were >10(9)/L. The primary end points were engraftment and incidence of acute GVHD. The secondary end points were the incidence of chronic GVHD, relapse, and overall disease-free survival. The study and control groups were comparable for age, sex, donor selections, conditioning regimens, and disease status. The median times to both neutrophil and platelet engraftment (ANC > 0.5 x 10(9)/L; platelets > 20 x 10(9)/L) were significantly faster in the study group than in the control group, at 15 versus 21 days (P Biol Blood Marrow Transplant 2002;8(5):261-7.
