Objectives: Chemotherapy-induced neutropenia in acute myeloid leukaemia (AML) is a risk factor for life-threatening infections. Early diagnosis and prompt interventions are associated with better outcomes, but the prediction of infection severity remains an open question. Recently, National Early Warning Score (NEWS) and quick sequential organ failure assessment (qSOFA) scores were proposed as warning clinical instruments predicting in-hospital mortality, but their role in the haematological context is still unknown., Methods: We retrospectively assess the predictive role of NEWS and qSOFA in a large and homogeneous cohort of adult AML patients treated with intensive chemotherapy. In a total of 1048 neutropenic episodes recorded in 334 consecutive patients, the scores were applied to predict outcomes on the same day of fever onset, and after 24 and 48 h from score calculation., Results: Both NEWS and qSOFA significantly predicted death, with more accuracy on the same day (NEWS AUROC 0.984 and qSOFA AUROC 0.969) and after 24 h (NEWS AUROC 0.928 and qSOFA AUROC 0.887), while remained moderately accurate after 48 h. Furthermore, also ICU admission was accurately predicted at fever onset and after 24 h., Conclusions: Both scores were useful tools in the management of post chemotherapy neutropenic febrile AML patients., (© 2023 John Wiley & Sons A/S.

In acute myeloid leukemia (AML), the detection of minimal residual disease (MRD) is still under investigation. The aim of the present retrospective study was to assess the role of Wilms tumor gene 1 (WT1) overexpression in a large monocentric cohort of AML patients. Among 255 enrolled patients, MRD was investigated in those in complete remission (CR) with an available WT1 at baseline (>250 copies) and at two further time-points: after induction (n=117) and prior allogeneic hematopoietic cell transplantation (allo-HCT), n=65. Baseline BM WT1 overexpression was not associated with response to induction (p=0.244). Median overall survival (OS) and disease-free survival (DFS) were significantly shorter in patients with >350 WT1 copies after induction compared to those with ≤350 (HR for mortality 2.13; 95% CI 1.14-3.97, p=0.018 and HR for relapse 2.81; 95% CI 1.14-6.93, p=0.025). Patients with WT1>150 copies pre allo-HCT had a significantly higher 2-year cumulative incidence of relapse (CIR) compared to those with WT1≤150 (HR 4.61; 95% CI 1.72-12.31, p=0.002). The prognostic role of WT1 overexpression resulted independent from other well-established risk factors. According to these results, WT1 overexpression might represent an additional MRD tool for risk stratification in patients classified nowadays in CR., (Copyright © 2017 Elsevier Ltd.

We report the clinical outcomes of 83 patients with acute lymphoblastic leukemia (median age, 46 years; range, 18-75 years) treated at our institution between 1999 and 2011. Treatment refers to clinical trials open for accrual at the time of diagnosis or to institutional guidelines. Upfront allografting was considered for younger high-risk patients. Seventy-eight of 83 (94%) patients achieved complete remission after induction, although 53% of them eventually relapsed. Forty of 70 patients younger than 61 years underwent allografting. The median follow-up was 7.4 years (range, 0.2-15.0 years). Overall, the 5-year overall survival (OS) and event-free survival (EFS) were 40% and 39%, respectively. In patients undergoing transplantation, OS and EFS at 5 years were both 53%, whereas in a nontransplantation setting, both OS and EFS were 35% at 5 years (P = .044 for both OS and EFS). By multivariate analysis, the independent predictors of OS and EFS were age and leukocytosis in the overall population and allografting in young patients., (Copyright © 2016 Elsevier Inc.
