Background Invasive pulmonary aspergillosis (IPA) is commonly associated with haematologic malignancies but also occurs with solid tumours. Aim To compare the diagnostic approaches and therapeutic outcomes for IPA between patients with haematologic malignancies and solid cancers. Methods A retrospective study was conducted evaluating consecutive cases of proven and probable IPA from 2004 to 2016. Patients >18 years of age with an underlying solid tumour, haematologic malignancy, or haematopoietic cell transplantation (HCT) within one year of IPA diagnosis were included. Findings Of the 311 patients analysed, 225 had haematologic malignancies and 86 had solid tumours. Patients with solid tumours were more likely to have had chronic obstructive pulmonary disease (COPD) or other pulmonary diseases, have Aspergillus fumigatus infections, and have received radiotherapy before IPA occurrence than were those with haematologic malignancies (all P<0.01). Antifungal monotherapy and voriconazole-based therapy were more often prescribed in the solid group (87% vs 56%, P<0.0001, and 77% vs 53%, P=0.0002, respectively). The median duration of primary antifungal therapy was longer in the solid group (64 days vs 20 days, P<0.0001). Complete or partial response to antifungal therapy was recorded in 66% of the solid group and 40% of the haematologic group (P=0.0001). At 12 weeks, overall mortality was similar in both groups, but IPA-attributable mortality was higher in the haematologic group (30% vs 18%, P=0.04). Conclusions Monotherapy was more often prescribed in patients with solid tumours than in patients with haematologic malignancies. Patients with solid tumours had better antifungal therapy response and lower 12-week IPA-attributable mortality than did those with haematologic malignancies.
