The long-term outcome of reduced-intensity allogeneic stem cell transplantation from a matched related or unrelated donor, or haploidentical family donor in patients with leukemia: a retrospective analysis of data from the China RIC Cooperative Group.

This study compared 6-year follow-up data from patients undergoing reduced-intensity conditioning (RIC) transplantation with an HLA-matched related donor (MRD), an HLA-matched unrelated donor (MUD), or an HLA-haploidentical donor (HID) for leukemia. Four hundred and twenty-seven patients from the China RIC Cooperative Group were enrolled, including 301 in the MRD, 79 in the HID, and 47 in the MUD groups. The conditioning regimen involved fludarabine combined with anti-lymphocyte globulin and cyclophosphamide.

[Multicenter report of nonmyeloablative allogeneic stem cell transplantation for hematologic diseases].

Objective: To observe the treatment effect and toxicity of nonmyeloablative allogeneic stem cell transplantation (NST) for hematologic diseases.

Methods: A total of 243 hematologic diseases patients received HLA-identical NST were enrolled in this study from 9 transplant centers of NST Cooperative Group in China. Nonmyeloablative conditioning regimen was based on fludarabine (Flud), rabbit anti-human thymocyte globulin (ATG), cyclophosphamide (CTX) (FAC), and plus cytarabine or busulfan (BU) etc.

Objective: To investigate the therapeutic effect of conditioning regimen containing fludarabine in nonmyeloablative allogeneic peripheral blood stem cells transplantation (NAST) in the treatment of hematological diseases.

Methods: Thirty-six patients with acute leukaemia, severe aplastic anaemia, MDS and myelofibrosis received NAST from HLA matched donors' G-CSF mobilized peripheral blood stem cells after nonmyeloabalative conditioning. The conditioning regimen consisted of CTX, Ara-C, CsA, anti-CD(3) antibody or anti-thymocyte globulin and with or without fludarabine.

Objective: To study the clinical significance of formation and conversion of hematopoietic mixed chimerism in nonmyeloablative allogeneic hematopoietic stem cell transplantation (NAST) in treatment of hematological diseases.

Methods: Nonmyeloablative pretreatment was given to 42 patients with hematological diseases, 26 males and 16 females with the median age of 37, that were matched with the donors in terms of HLA, such as CD3 monoclonal antibody, cyclosporine A, cyclophosphamide (CTX) and cytarabine for patients with leukemia among which 6 were given fludarabine in addition, and CTX and antilymphocyte globulin for patients with myeloproliferative disease and aplastic anemia, thus practicing nonmyeloablative allogeneic stem cell transplantation (NAST). The incidence of graft-versus-host disease (GVHD) and survival were observed.

[The clinical research of nonmyeloablative allogeneic peripheral blood hematopoietic stem cells transplantation for hematological diseases].

Objective: To explore the significance of nonmyeloablative allogeneic peripheral blood hematopoietic stem cell transplantation in the treatment of hematological diseases.

Methods: A nonmyeloablative conditioning regimen consisted of CD(3) monoclonal antibody, cyclosporine A, cyclophosphamide and cytarabine was used for allogeneic stem cell transplantation in 33 patients with hematological diseases. Of them, 11 were acute leukemia (AL) in first complete remission (CR(1)), 4 AL-CR(2) approximately 3, 3 refractory AL, 4 severe aplastic anemia (SAA), 7 chronic myeloid leukemia (CML), 2 myelodysplastic syndrome, 1 each of chronic lymphocytic leukemia (CLL) and myelofibrosis.

[Significance of serological test of blood group in nonmyeloablative allogeneic peripheral blood stem cell transplantation of patients with acute leukemia].

The purpose of this study is to explore the clinical significance of RBC blood group serological test in nonmyeloablative allogeneic peripheral blood stem cell transplantation (NAPBSCT) of ABO group incompatibility in 4 patients with acute leukemia. ABO and MN blood group of donors and recipients were determined by hemagglutination test and Rh blood group by Diana Gel phenotype Rh card. The changes of blood group in recipients were observed and implant of donor cells was monitored by short tandem repeat-PCR method.
