T cells engineered to express chimeric antigen receptors (CARs) are a promising modality to treat refractory cancers. CD19 CAR-T therapy has achieved remarkable responses in against B-cell lymphomas, however, challenges persist for acute myeloid leukemia (AML) and solid malignancies. B7H3 is an immune regulatory molecule that is highly expressed in various tumor cells. Its abnormal expression in acute AML and esophageal squamous cell carcinoma (ESCC) is closely related to tumor progression. 

High-grade glioma (HGG) cells reactivate neurodevelopmental programs regulated by ion channels to drive tumor progression. The activity of voltage-gated sodium channels (VGSCs) is fundamental to development, a target of blood-brain barrier (BBB)-permeable FDA-approved drugs, and aids tumor advancement in several cancers. However, the contribution of VGSC activity to HGG pathology remains unknown.

Childhood renal masses comprise a heterogeneous group of conditions that have a wide range of presentations. This review outlines an approach to the diagnostic work-up of childhood renal masses and discusses the most common presentations and treatments. Renal tumours make up 5% of childhood cancer in Australia, with Wilms tumour being the most common under age 10 years.

Cancer cells are addicted to polyamines, polycations essential for cellular function. While dual targeting of cellular polyamine biosynthesis and polyamine uptake is under clinical investigation in solid cancers, preclinical and clinical studies into its potential in haematological malignancies are lacking. Here we investigated the preclinical efficacy of polyamine depletion in acute leukaemia.

OLIG2-expressing tumor stem cells have been shown to drive recurrence in Sonic Hedgehog (SHH)-subgroup medulloblastoma (MB) and patients urgently need specific therapies to target this tumor cell population.

ETV6::RUNX1 is one of the most common recurrent genomic abnormalities in acute lymphoblastic leukaemia (ALL) and is associated with a good prognosis. High expression of NTRK1, encoding tropomyosin receptor kinase A (TrkA), confers a poor prognosis in other malignancies and may contribute to therapy resistance in patients with ETV6::RUNX1 B-ALL.

Cold atmospheric plasma (CAP) is a safe and effective alternative to radiotherapy for cancer treatment. Its anticancer effects are attributed to increased intracellular reactive oxygen species (ROS). Glutathione, a key antioxidant derived from glutamine, is critical for cell proliferation. This study investigated whether CAP-induced ROS elevation results from reduced glutamine-glutathione conversion and elucidates the underlying mechanisms.

Glioblastoma, a lethal high-grade glioma, has not seen improvements in clinical outcomes in nearly 30 years. Ion channels are increasingly associated with tumorigenesis, and there are hundreds of brain-penetrant drugs that inhibit ion channels, representing an untapped therapeutic resource. The aim of this exploratory drug study was to screen an ion channel drug library against patient-derived glioblastoma cells to identify new treatments for brain cancer.

Acute lymphoblastic leukaemia (ALL) is the most common paediatric malignancy and remains one of the most common causes of cancer-related death in children and adolescents. Five-year overall survival rates now exceed 90% with current multidrug chemotherapeutic regimens.
