Abstract

Human development Index (HDI) is used by the United Nations Organization to measure socioeconomic achievements of countries. We evaluated association of HDI with rates and outcomes of hematopoietic stem cell transplantation (HSCT) for patients with acute leukemia. For the analysis of HSCT rates, all adults with acute leukemia (n=16403) treated in 30 European countries, between 2001 - 2005 were included. Association of HDI with the outcome was analyzed for 2015 patients with acute myeloid leukemia treated with myeloablative allotransplantation. Countries were classified according to HDI percentiles into 5 categories. Highly significant correlation was found for HDI and the total number of HSCT per population (R=0.78; p<0.0001), as well as separately for sibling-HSCT (R=0.84; p<0.0001), unrelated-HSCT (R=0.66; p<0.0001) and autologous-HSCT (R=0.43; p=0.02). The probabilities of LFS for 5 consecutive groups of countries with increasing HDI were as follows: 56%, 59%, 63%, 58%, and 68% (p=0.01). In a multivariate analysis transplants performed in countries belonging to the upper HDI category were associated with significantly higher LFS compared to the remaining ones (HR=1.36, p=0.008), which resulted mainly from reduced risk of relapse (HR=0.72, p=0.04). We conclude that in Europe, the HDI is associated with both rates and results of HSCT for acute leukemia.
