Article Synopsis
  • A study investigated 66 children with resistant acute myeloid leukaemia (AML) from a larger cohort, revealing that older age (10 years+) and high white-blood-cell counts at diagnosis are significant risk factors for resistant disease.
  • The five-year overall survival rate for these patients was found to be only 38%, but among those who achieved complete remission (CR) after salvage chemotherapy, the survival rate rose to 57%.
  • The study concluded that nearly 40% of children with primary resistant AML can be successfully treated with salvage therapy followed by allogeneic stem cell transplantation, but additional chemotherapy after two unsuccessful attempts did not improve outcomes.

Introduction: Analysis of measurable residual disease (MRD) is increasingly being implemented in the clinical care of children and adults with acute myeloid leukaemia (AML). However, MRD methodologies differ and discordances in results lead to difficulties in interpretation and clinical decision-making. The aim of this study was to compare results from reverse transcription quantitative polymerase chain reaction (RT-qPCR) and multiparameter flow cytometry (MFC) in childhood AML and describe the kinetics of residual leukaemic burden during induction treatment.

Aim: Risk of treatment-related life-threatening toxicity is high in childhood acute myeloid leukaemia (AML), and access to intensive care units (ICU) is crucial. We explored the ICU admission rate and outcome after intensive care in childhood AML in Sweden.

Methods: Patients diagnosed between 2008 and 2016 were identified from the Swedish Childhood Cancer Registry (SCCR), a national quality registry.

Objectives: Despite progress in the treatment of childhood acute lymphoblastic leukemia, severe complications are common, and the need of supportive care is high. We explored the cumulative prevalence, clinical risk factors, and outcomes of children with acute lymphoblastic leukemia, on first-line leukemia treatment in the ICUs in Sweden.

Design: A nationwide prospective register and retrospective chart review study.

Background: Extracorporeal membrane oxygenation (ECMO) is used in severe respiratory and/or circulatory failure when conventional critical care fails. Studies on patients with hematologic malignancies on ECMO have shown contradictory results; immunosuppression and coagulopathy are relative contraindications to ECMO.

Observations: This nationwide Swedish retrospective chart review identified 958 children with hematologic malignancies of whom 12 (1.

Given that 30-40% of children with acute myeloid leukaemia (AML) relapse after primary therapy it is important to define prognostic factors and identify optimal therapy. From 1993 to 2012, 543 children from the Nordic countries were treated according to two consecutive protocols: 208 children relapsed. The influence of disease characteristics, first line treatment, relapse therapy and duration of first remission on outcome was analysed.
