    Abstract:
    BACKGROUND & OBJECTIVE: Hematopoietic stem cell transplantation could improve the prognosis of malignant hematologic diseases. Peripheral blood stem cell transplantation (PBSCT) has been gradually used as an alternative to bone marrow transplantation (BMT). This study was to observe the efficacy of allogeneic PBSCT (allo-PBSCT) or autologous PBSCT (auto-PBSCT) on malignant hematologic diseases. METHODS: From Jul. 2003 to May 2006, 53 patients with malignant hematologic diseases underwent PBSCT in the First Affiliated Hospital of Zhengzhou University. PBSCs were mobilized with granulocyte colony-stimulating factor (G-CSF) or chemotherapy combined with G-CSF. Auto-PBSCT group received infusion of CD34+ cells at a median of 3.0x10(6) cells/kg; allo-PBSCT group received infusion of CD34+ cells at a median of 6.2x106 cells/kg. MAC regimen was used in auto-PBSCT group as conditioning regimen; amended BU/CY regimen was used in allo-PBSCT group. Methotrexate (MTX) combined with cyclosporine A (CsA) and MMF was used for graft-versus-host disease (GVHD) prophylaxis. Antilymphocyte globulin (ALG) was used in 1 patient with 1 mismatched locus in allo-PBSCT group. RESULTS: The median time for neutrophils to reach 0.5x10(9)/L and platelets to reach 20x10(9)/L were 13 days and 19 days in auto-PBSCT group, 12 days and 15 days in allo-PBSCT group. In allo-PBSCT group, grade I-III acute GVHD occurred in 31.4% cases, and chronic GVHD developed in 71.4% cases. The relapse rate was 38.9% in auto-PBSCT group and 5.7% in allo-PBSCT group. The 700-day disease-free survival rate (DFS) was 57.9% in auto-PBSCT group, and 69.5% in allo-PBSCT group. CONCLUSIONS: PBSCT can provide rapid hematopoietic reconstitution. It is a better choice for the cure of malignant hematologic diseases.
