Abstract

Hematopoietic stem cell transplantation (HSCT) has evolved from an experimental to a successful treatment modality reaching worldwide 80.000 HSCT/year. Distribution and trends of HSCT, however, remain heterogeneous. Activities range from none to more than 511/10 million population between countries and regions. Here, we report on a successful autologous and allogeneic HSCT program for adult and pediatric patients started two decades ago in Northern Africa. From 1998 to December 2017, a total of 2828 HSCT was performed of which 2059 were allo-HSCT (1474 adults and 585 children). The activities were analyzed according to indication, donor type, stem cell source, and trends over time. There was a significant difference in indications according to age. Adult patients were transplanted more often for hematological malignancies. In children, the indications were distributed equally between malignant and non-malignant diseases. Overall activities increased substantially in AML and to a lower extent in ALL and CLL despite sharp reduction of activity in CML after 2005. Finally, a higher transplantation rate (33/10 million population) was reached as compared to most regions of the world except Europe and USA/Canada. Overall survival in children with AML was 56.0% at 15 years, in adults 61.3% at 5 years, and in patients with CML 55.5% at 15 years without difference between reduced intensity condition (RIC) and myeloablative conditioning (MAC). Patients with Ph+ ALL had the lowest survival reaching 26.7% at 5 years. Highest survival was observed in patients with aplastic anemia, Fanconi anemia, and thalassemia reaching 77.3%, 73.5%, and 75.7% at 15 years respectively. Long distances and late referral remain a challenge for this large country.
