Abstract:
To investigate the therapeutic effects and associated complications of allogeneic peripheral blood stem cell transplantation (allo-PBSCT), 40 patients with various malignant hematopoietic diseases received allo-PBSCT. The preparative regimens were based on BUCY2 or modified BUCY2. The acute graft versus host disease (aGVHD) was prevented by cyclosporin A and shortterm MTX regimen in all patients. Two patients from donors with one fully mismatched HLA on DRB1 locus and 4 from unrelated donor also administered Zenapox (CD25 MAb) at dosage of 1 mg/kg every day on the day before transplantation and day 4 after transplantation. These 6 patients were also treated with mycophenolate mofetil (MMF). Transfusion of the donor cells: The median of the transfused nucleated cells was 5.38 × 108/kg and that of the CD34+ cells was 7.8 × 106/kg respectively. All the patients gained hematopoietic reconstruction except one who died of infection before engraftment. Seven patients got Ⅱ°-Ε° aGVHD and the incidence was 17.5 %. Fourteen patients got cGVHD and the incidence was 53.8 % in the patients who survived over 6 months.Twenty-eight patients had fever or other characteristics of infection. The median follow-up time was 13.8 months. The incidence of transplantation related mortality (TRM) was 17.5 % and 2 patients relapsed (5.0 %). It was concluded that allo-PBSCT can reconstruct hematopoiesis quickly and is a favorable therapeutic method for leukemia.
