This study was aimed to investigate clinical characteristics and treatment outcomes of pulmonary invasive fungal infection (IFI) among patients with hematological malignancy. All patients with hematological malignancy who were treated at a medical centre from 2008 to 2013 were evaluated. Pulmonary IFI was classified according to the European Organization for Research and Treatment of Cancer 2008 consensus. During the study period, 236 (11.3%) of 2083 patients with hematological malignancy were diagnosed as pulmonary IFI, including 41 (17.4%) proven, 75 (31.8%) probable, and 120 (50.8%) possible cases. Among the 116 patients of proven and probable cases of pulmonary IFI, aspergillosis alone (n = 90, 77.6%) was predominant, followed by cryptococcosis alone (n = 9, 7.8%), and mucormycosis (n = 4, 3.4%). The overall incidence of patients with pulmonary IFI was 5.9 per 100 patient-years. The highest incidence (per 100 patient-year) was found in patients with acute myeloid leukaemia (13.7) followed by acute lymphoblastic leukaemia (11.3), and myelodysplastic syndrome/severe aplastic anaemia (6.7). Fourteen (5.9%) of the 236 patients with pulmonary IFI died within 12 weeks after diagnosis of pulmonary IFI. Univariate analysis revealed that elderly age (>65 years) (P = 0.034), lack of response to anti-fungal treatment (P < 0.001), and admission to the intensive care unit (ICU) (P < 0.001) were predictors of poor prognosis. However, only admission to the ICU was an independent predictor of poor prognosis for 12-week mortality (P = 0.022) based on multivariate analysis. Patients with acute leukaemia and myelodysplastic syndrome/severe aplastic anaemia were at high risk of pulmonary IFI.
