International audience. Invasive aspergillosis (IA) during induction chemotherapy of acute myeloid leukemia (AML) could worsen the prognosis. Our objective was to study how the development of IA during AML interferes with the therapeutic strategy and to evaluate its impact on the short- and long-term survival. Newly diagnosed AML patients between the years 2004 and 2007 were retrospectively analyzed. The outcome was death of the patient. A Cox proportional hazards model with the diagnosis of IA and post-induction response evaluation as the main exposure was fitted. Overall, 262 patients were analyzed and 58 IA were observed. The 2-year survival of patients having had remission of AML was 54% and, for patients with failure of chemotherapy, it was 5% (p < 0.001). The 2-year survival of patients having had IA was 14%, and without IA, it was 32% (p = 0.01). Multivariate analysis showed that IA was associated with a higher risk of death in case of remission compared to no IA (hazard ratio [HR] = 1.66 [1.05-2.65], p = 0.031) and also in case of failure (HR = 6.43, p < 0.001). IA was associated with an increased risk of death for patients if they were either in remission or in failure after induction chemotherapy.
