Brief Summary

Allogeneic stem cell transplantation (Allo-HSCT) is the effective and even the only treatment for hematological malignancies. The "GIAC" protocol established by our center has successfully crossed the HLA barrier in HLA-mismatched/haploidentical HSCT. The protocol entails the following: treating donors with granulocyte colony-stimulating factor (G-CSF) to induce donor immune tolerance, intensified immunologic suppression to both promote engraftment and to prevent GVHD, antithymocyte globulin (ATG) was included for the prophylaxis of GVHD and graft rejection, and combination of G-CSF-primed bone marrow harvest (G-BM) and G-CSF-mobilized peripheral blood stem cell harvest (G-PB) as the source of stem cell grafts. But peripheral blood transplantation is still prevalent. Compared with BM, G-PB is more convenient to collect, and the number of T lymphocytes and CD34+ cells is higher. It is reported that G-PB has a higher implantation rate and even a higher disease-free survival rate in sibiling-identical transplantation compared with BM transplantation, whereas there were also reports with different conclusions. This prospective, one-arm clinical cohort study aims to evaluate the safety and efficacy of haplotype peripheral blood stem cell transplantation (PBSCT) in the treatment of acute leukemia.

Outcome Measures

Primary Outcomes (1)

  • engraftment rate

    Neutrophil recovery was defined as an absolute neutrophil count(ANC) of 0.5×10\^9/L or more for three consecutive days and platelet recovery, as 20×10\^9/L or more for seven consecutive days without transfusion.

    one year after transplantation

Secondary Outcomes (5)

  • cumulative incidence of acute graft-versus-host disease(GVHD)

    one year after transplantation

  • cumulative incidence of chronic GVHD at one year

    one year after transplantation

  • cumulative incidence of relapse at one year

    one year after transplantation

  • cumulative incidence of non-relapse mortality (NRM) at one year

    one year after transplantation

  • overall survival at one year

    one year after transplantation
