Abstract
BACKGROUND To provide insight into the perspectives of children and young adults with transfusion-dependent thalassemia and sickle cell disease and their caregivers regarding the decision for hematopoietic stem cell transplantation (HSCT). PROCEDURE A qualitative longitudinal multicenter study. Data collection consisted of 40 audio-recorded conversations between physicians and families and 77 interviews with patients and/or caregivers related to 27 unique cases, collected at different time points throughout the decision-making process. RESULTS Conversations and interviews revealed "hoping for a normal life" as an overarching theme, consisting of four main topics: (i) "Building a frame of reference" refers to a process where patients or families try to obtain comprehensive information on HSCT and translate this to their situation to decide. (ii) "Balancing between loss and benefit" reports the process of considering the advantages and disadvantages of continuing with supportive care to treat their disease versus choosing HSCT. (iii) "Experiencing the impact of HSCT" describes the impactfull experience of the HSCT period by those who chose HSCT. (iv) "Balancing again" refers to reflecting on the decision made. CONCLUSIONS The hope for a normal life guided the decision-making process, described as a constant balance between the impact of the disease and HSCT. A structured approach to explore patients' and caregivers' perspectives on HSCT decision-making is needed, where specifically discussing the impact of the disease and hope for a normal life need to be integrated in the process.

Abstract
Significant advances in supportive care for patients with transfusion-dependent thalassemia major (TDT) have improved patients' life expectancy. However, transfusion-associated iron overload remains a significant barrier to long-term survival with good quality of life. Today, allogeneic hematopoietic stem cell transplantation (HSCT) is the current curative standard of care. Alongside selection of the best available donor, an optimized conditioning regimen is crucial to maximize outcomes for patients with TDT undergoing HSCT. The aim of this retrospective analysis was to investigate the role of busulfan-fludarabine-based and treosulfan-fludarabine-based conditioning in TDT patients undergoing HSCT. We included 772 patients registered in the European Society for Blood and Marrow Transplantation (EBMT) database who underwent first HSCT between 2010 and 2018. Four hundred ten patients received busulfan-fludarabine-based conditioning (median age 8.6 years) and 362 patients received treosulfan-fludarabine-based conditioning (median age 5.7 years). Patient outcomes were retrospectively compared by conditioning regimen. Two-year overall survival was 92.7% (95% confidence interval: 89.3-95.1%) after busulfan-fludarabine-based conditioning and 94.7% (95% confidence interval: 91.7-96.6%) after treosulfan-fludarabine-based conditioning. There was a very low incidence of second HSCT overall. The main causes of death were infections, graft-versus-host disease, and rejection. In conclusion, use of busulfan or treosulfan as the backbone of myeloablative conditioning for patients with TDT undergoing HSCT resulted in comparably high cure rates. Long-term follow-up studies are warranted to address the important issues of organ toxicities and gonadal function.
