Cyclosporine A and mycophenolate mofetil vs cyclosporine A and methotrexate for graft-versus-host disease prophylaxis after stem cell transplantation from HLA-identical siblings. 
The combination of Cyclosporin A (CSA) and Methotrexate (MTX) is considered to be the standard regimen for the prevention of graft-versus-host disease (GVHD) after stem cell transplantation (SCT) from HLA-identical siblings.  Mycophenolate Mofetil (MMF) has been widely used for GVHD prophylaxis after nonmyeloablative SCT, but experience following myeloablative therapy is still limited.  We retrospectively compared CSA/MTX and CSA/MMF in 93 patients (median age 35 years, range 17-59 years, male subjects 48, female subjects 45) with acute myeloid leukemia (n=33), myelodysplastic syndrome (MDS) (n=3), acute lymphoblastic leukemia (ALL) (n=20) or chronic myeloid leukemia (n=37) who received CSA/MMF (n=26) or CSA/MTX (n=67) as GVHD prophylaxis following high-dose therapy and allogeneic SCT from HLA-identical siblings.  No statistically significant differences were found in overall survival, relapse rate, treatment-related mortality and acute or chronic GVHD.  Time to myeloid recovery was significantly shorter in patients who received CSA/MMF.  We conclude that the combination of CSA/MMF appears equivalent to CSA/MTX for GVHD prophylaxis in patients receiving conventional-intensity SCT from HLA-identical siblings.
