Abstract
- The best approach for allogeneic haematopoietic stem cell transplantations (allo HCT) in patients with chronic lymphocytic leukaemia ( CLL) is unknown. We therefore analysed the impact of procedure- and centre-related factors on 5-year event-free survival ( EFS) in a large retrospective study. Data of 684 CLL patients who received a first allo HCT between 2000 and 2011 were analysed by multivariable Cox proportional hazards models with a frailty component to investigate unexplained centre heterogeneity. Five-year EFS of the whole cohort was 37% (95% confidence interval [ CI], 34-42%). Larger numbers of CLL allo HCTs (hazard ratio [ HR] 0·96, P = 0·002), certification of quality management ( HR 0·7, P = 0·045) and a higher gross national income per capita ( HR 0·4, P = 0·04) improved EFS. In vivo T-cell depletion ( TCD) with alemtuzumab compared to no TCD ( HR 1·5, P = 0·03), and a female donor compared to a male donor for a male patient ( HR 1·4, P = 0·02) had a negative impact on EFS, but not non-myeloablative versus more intensive conditioning. After correcting for patient-, procedure- and centre-characteristics, significant variation in centre outcomes persisted. In conclusion, further research on the impact of centre and procedural characteristics is warranted. Non-myeloablative conditioning appears to be the preferable approach for patients with CLL.
