| Description | Reduced-intensity conditioning (RIC) is being widely used for allogeneic stem cell transplantation (SCT). Here we present our long-term experience with RIC regimen consisting of fludarabine (6x30 mg/m2), busulfan (2x4 mg/kg) and antithymocyte globulin (ATG Fresenius, 4x10 mg/kg) (Flu-Bu-ATG) at cohort of 71 patients (pts) with various hematological malignancies, 65 pts had unrelated donor, 6 related donor. Patients were transplanted in period 1998-2008, aim of our work was to evaluate effectivity and toxicity of RIC Flu-Bu-ATG. Median age was 50 years. Overall response rate was 87%; 83% of pts achieved complete and 4% partial response. The incidence of acute and chronic GVHD was 35% and 52%. The cumulative incidence of non-relapse mortality after 1 year and 4 years were 8% and 14%, respectively. With median follow-up of 55.0 months after SCT, 2- and 4-year event-free survival (EFS) was 49.0% and 40.3%, overall survival (OS) was 73.2% and 62.6%. Gender, age at SCT, type of donor, disease status at SCT, previous autologous transplantation, achievement of complete chimerism to day +100 did not significantly influence EFS and OS. On multivariate analysis, no presence of chronic GVHD (p = 0.029, HR:2.5), other diagnosis than CML (p = 0.018, HR:4.6) and dose of CD34+ cells lower than 5x106/kg (p = 0.010, HR:2.8) are statistically significant for shorter OS. In conclusion, the Flu-Bu-ATG protocol can be considered as a RIC regimen combining effective disease control and acceptable toxicity profil. |
