Resumo

Despite advances in supportive measures, acute myeloid leukemia (AML) remission induction still has a high mortality rate in real-world studies as compared to prospective reports. We analyzed data from 206 AML adult patients treated with conventional chemotherapy. The primary endpoint was the 60-day mortality rate, aiming to find risk factors and to examine the role of anti-infection prophylaxis. The 60-day mortality rate was 26%, raising to 41% among those older than 60 years. Complete response was documented at the end of induction in 49%. The final survival model showed that age > 60 years (HR 3.2), Gram-negative colonization (HR 3), monocytic AML (HR 1.8), C-reactive protein (CRP) > 15 mg/dL (HR 10), and an adverse risk in the genetic stratification (HR 3) were associated with induction death. Multidrug-resistant bacteria colonization, thrombosis, and AKI were documented in 71%, 12%, and 66% of the cohort, respectively. Antibacterial and antifungal prophylaxis did not improve outcomes in this study. Our report corroborated the higher mortality during AML induction compared to real-world data from the USA and Europe. In line with other publications, age and cytogenetic stratification influenced early death in this cohort. Noticeably, Gram-negative colonization, monocytic AML, and CRP were also significant to early mortality. (AU)
