title: [Treatment of leukemia by allogeneic peripheral blood stem cell transplantation from sibling donors].
abstract: This study was aimed to observe the efficacy and side effects of allogeneic peripheral blood stem cell transplantation (Allo-PBSCT) in patients with leukemia. The donors were siblings matched with t HLA-A, B, DR loci of recipient. After mobilization with 250 microg/day rhG-CSF for 5 days, peripheral blood stem cells were collected 1 to 2 times. 4 patients with leukemia received 6.78 x 10(8)/kg +/- 1.96 x 10(8)/kg (5 x 10(8)/kg-8.67 x 10(8)/kg) peripheral blood mononuclear cells, which contained 15.02 x 10(6)/kg +/- 8.93 x 10(6)/kg (5.3 x 10(6)/kg-24.23 x 10(6)/kg) CD34(+) cells after modified Bu/Cy conditioning regimen and MTX + CsA + MMF were given for prophylaxis of aGVHD. The results showed that the leukocyte was reduced to the lowest at pretransplantation 2 days-posttransplantation 2 days. Neutrophil amount >0.5 x 10(9)/L was found at 11 - 17 day after transplantation, platelet >50 x 10(9)/L-at 11 - 55 days after transplantation. Out of 4 patients, aGVHD, cGVHD and infection took place in 2,2 and 2 cases, respectively. Bone marrow displayed hematopoietic recovery at 28 day after transplantation, examination of STR in DNA revealed proliferation of donor cells in patients. In conclusion, Allo-PBSCT in combination with modified Bu/Cy conditioning regimen and MTX + CsA + MMF prophylaxis of aGVHD is safety and reliable for treatment of leukemia.
