For most chronic myeloid leukaemia patients the option of a potentially curative allogeneic stem cell transplantation is not available because of age or lack of donor. Alternative therapy with interferon-alpha appears to prolong survival but is probably not curative. The aim of the study is to analyse the clinical results of the first Hungarian autologous transplantations in CML. Methods: Seven patients were treated with ICE-based regimen plus G-CSF with the aim of mobilising and collecting Ph-negative peripheral stem cells in the setting of autologous transplant program. Five patients had CML in first chronic phase and two in accelerated phase. All patients have been previously treated with interferonalpha. Results: Median value and ranges for harvested mononuclear cells, CD34+ cells and CFU-GM were: 5.65×108/kg (2.61-11.38), 1.48×106/kg (0.216-3.5) and 3.43×10 4/kg (0.243-11.6), respectively. Four out of seven autologous grafts have been transplanted. Busulfan conditioning was used in one case and TBI/Cy conditioning in three patients. All patients are alive and well post-transplant being on interferon-alpha therapy. Conclusions: Based on the clinical advantages of autologous transplantation including long-term chronic phase, achievement of second chronic phase and improved response to interferon-alpha therapy, the procedure can offer an alternative treatment in CML in lack of HLA-identical donor.
