Improved nonmyeloablative allogeneic peripheral blood stem cell transplantation for severe aplastic anemia / 白血病·淋巴瘤

ABSTRACT

Objective To summarize the experience of improved nonmyeloablative hematopoietic stem cell transplantation(NSCT) in the treatment of severe aplastie anemia. Methods Seventeen patients with Severe Aplastic Anemia received NSCT after a nonmyeloablative conditioning.The patients were conditioned with decreased dosage of immunosuppressive agents of CTX and anti-lymphoid cell globulin or anti-thymus gland cell globulins;CsA and MMF were used to prevent the graft-versus-host disease (GVHD) after transplantation. Results 75 % of severe aplastic anemia in patients with type Ⅰ and 60 % of severe aplastic anemia in patients with type Ⅱ achieved rapid hematopoietic reconstitution, with good prognosis and implantation rate with fewer complieations and light symptoms were observed. Conclusion NSCT is an effective treatment of severe aplastic anemia.
