Abstract: Invasive fungal infection (IFI) is a growing cause of morbidity and mortality among patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We retrospectively reviewed the records of 408 patients undergoing allo-HSCTs during the period November 1998 to December 2009, analyzed the incidence and risk factors of IFI, and examined the impact of IFI on overall survival. A total of 92 (22.5%) episodes suffered proven or probable IFI (4 patients were proven, 88 patients were probable). Candida was the most common pathogen for early IFI, and mold was the most frequent causative organism for late IFI. A prior history of IFI, human leukocyte antigen (HLA) mismatch, long-time neutropenia, and acute graft-versus-host-disease (GVHD) were risk factors for early IFI. A prior history of IFI, corticosteroid therapy, cytomegalovirus (CMV) disease, and chronic GVHD were risk factors for late IFI. IFI-related mortality was 53.26%. The 12-year overall survival (OS) rate for IFI was significantly lower than that of patients without IFI (41.9% vs. 63.6%, P<0.01).
