Receptor mutation is not a common mechanism of naturally occurring glucocorticoid resistance in leukaemia cell lines

Glucocorticoids (GCs) are among the most important drugs for the treatment of acute lymphoblastic leukaemia (ALL).

Dose-dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

In vitro liver models combined with metabolomics approaches offer promising alternatives to animal testing in toxicology. In this study, we investigated concentration-dependent effects of hydrogen peroxide on the intra- and extracellular metabolome of HepG2 cells using 1H Nuclear Magnetic Resonance spectroscopy. 

Targeted Therapy for Systemic Epstein-Barr Virus–Positive T-Cell Lymphoma of Childhood

Systemic Epstein-Barr virus-positive T-cell lymphoma of childhood (STCLC) is a rare and highly aggressive malignancy with a dismal prognosis and no standard curative treatment. This report describes the first reported case of STCLC in a White child who, after experiencing failure with intensive chemotherapy regimens, achieved a complete response following targeted immunotherapy.

Acute Lymphoblastic Leukemia in Infants: A Distinctive, High-Risk Subtype of Childhood Acute Lymphoblastic Leukemia

Acute lymphoblastic leukemia (ALL) in infants younger than 1 year of age is an aggressive, high-risk subtype of childhood ALL. Infant ALL with KMT2A-r is characteristically poorly responsive to chemotherapy and hematopoietic stem cell transplantation. New strategies, such as molecularly targeted therapies and immunotherapies, are in development and show promise in preclinical models and early phase studies.

Minimal residual disease and outcome characteristics in infant KMT2A-germline acute lymphoblastic leukaemia treated on the Interfant-06 protocol

The outcome of infants with KMT2A-germline acute lymphoblastic leukaemia (ALL) is superior to that of infants with KMT2A-rearranged ALL but has been inferior to non-infant ALL patients. Here, we describe the outcome and prognostic factors for 167 infants with KMT2A-germline ALL enrolled in the Interfant-06 study.

Invasive fungal disease in children with acute myeloid leukaemia: An Australian multicentre 10-year review

Invasive fungal disease (IFD) is a common and important complication in children with acute myeloid leukaemia (AML). We describe the epidemiology of IFD in a large multicentre cohort of children with AML.

Case Report: Long-Term Survival of a Pediatric Patient With an Intra-Abdominal Undifferentiated Carcinoma of Unknown Primary

This report provides detailed characterization of carcinoma of unknown primary (CUP) in a young child and in the absence of defined therapeutic guidelines for pediatric CUP, the successful treatment strategy described should be considered for similar cases.

Outcomes for Australian children with relapsed/refractory acute lymphoblastic leukaemia treated with blinatumomab

We report on the Australian experience of blinatumomab for treatment of 24 children with relapsed/refractory precursor B-cell acute lymphoblastic leukaemia (B-ALL) and high-risk genetics, resulting in a minimal residual disease (MRD) response rate of 58%, 2-year progression-free survival (PFS) of 39% and 2-year overall survival of 63%. In total, 83% (n = 20/24) proceeded to haematopoietic stem cell transplant, directly after blinatumomab (n = 12) or following additional salvage therapy (n = 8).
