Since transplantation cannot be performed immediately after the diagnosis of chronic myelogenous leukemia (CML), interferon treatment is usually required. This study aims to analyze the effects of interferon-alpha (IFN) treatment on allogeneic stem cell transplantation (SCT) outcome. A total of 106 patients aged 16-47 years and transplanted from HLA-identical sibling donors for CML in chronic phase (CP) were evaluated. In all, 48 had received IFN-alpha for a median duration of 5 months (1-18 months) until a median of 1 month prior to transplantation. Of the patients, 50 have received bone marrow transplant (BMT) whereas 56 have received peripheral blood stem cells (PBSCT) between 1991 and 1999 in three major transplant centers in Turkey. Patient characteristics in both groups were similar. More hematological responders were present in the IFN(+) patients (P=0.0001). No difference was found in engraftment kinetics. The incidences of acute or chronic graft-versus-host disease (GVHD), relapse and graft failure were similar in all patients regardless of stem cell source. Overall survival (OS) and disease-free survival (DFS) at 2 years were similar for both IFN(+) or (-) patients following SCT. With multivariate analysis, pretransplant IFN-alpha use, stem cell source, transplant year and CD34+ cell content were not found to be risk factors for OS. In conclusion, prior IFN exposure did not impair BMT or PBSCT outcome.
