Historically, invasive aspergillosis (IA) has been a major barrier for allogeneic hematopoietic stem cell transplantation (allo-HSCT). The influence of invasive IA on long-term survival and on transplant-related complications has not been investigated in a larger patient cohort under current conditions. Our aim was to analyze the long-term outcome of patients undergoing allo-HSCT with a history of prior IA. We used European Society for Blood and Marrow Transplantation database data of first allo-HSCTs performed between 2005 and 2010 in patients with acute leukemia. One thousand one hundred and fifty patients with data on IA before allo-HSCT were included in the analysis. The median follow-up time was 52.1 months. We found no significant impact of IA on major transplant outcome variables such as overall survival, relapse-free survival, non-relapse mortality, cumulative incidence of acute GvHD grade II-IV, chronic GvHD, pulmonary complications and leukemia relapse. However, we found a trend toward lower overall survival (P=0.078, hazard ratio (HR) (95% confidence interval (CI)): 1.16 (0.98, 1.36)) and higher non-relapse mortality (P=0.150, HR (95% CI): 1.19 (0.94, 1.50)) in allo-HSCT recipients with pre-existing IA. Our data suggest that a history of IA should not generally be a contraindication when considering the performance of allo-HSCT in patients with acute leukemia.

Abstract
Historically, invasive aspergillosis (IA) has been a major barrier for allogeneic hematopoietic stem cell transplantation (allo-HSCT). The influence of invasive IA on long-term survival and on transplant-related complications has not been investigated in a larger patient cohort under current conditions. Our aim was to analyze the long-term outcome of patients undergoing allo-HSCT with a history of prior IA. We used European Society for Blood and Marrow Transplantation database data of first allo-HSCTs performed between 2005 and 2010 in patients with acute leukemia. One thousand one hundred and fifty patients with data on IA before allo-HSCT were included in the analysis. The median follow-up time was 52.1 months. We found no significant impact of IA on major transplant outcome variables such as overall survival, relapse-free survival, non-relapse mortality, cumulative incidence of acute GvHD grade II-IV, chronic GvHD, pulmonary complications and leukemia relapse. However, we found a trend toward lower overall survival (P=0.078, hazard ratio (HR) (95% confidence interval (CI)): 1.16 (0.98, 1.36)) and higher non-relapse mortality (P=0.150, HR (95% CI): 1.19 (0.94, 1.50)) in allo-HSCT recipients with pre-existing IA. Our data suggest that a history of IA should not generally be a contraindication when considering the performance of allo-HSCT in patients with acute leukemia.
