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.

Parents of children with acute lymphoblastic leukaemia (ALL) experience emotional distress throughout their child's treatment course. This study describes the psychological experience of Australian and New Zealand parents of children diagnosed with ALL. 

Local treatment of pelvic Ewing Sarcoma (EWS) is czhallenging due to complex anatomy and potential complications. Local therapy may be deferred to maintain chemotherapy dose-intensity, but the impact of this delay on outcomes remains unclear.

It is now well accepted that germline or de novo genetic alterations predispose to cancer development, especially during childhood. Among them, constitutive trisomy 21, also known as Down syndrome (DS), has been shown to predispose to acute leukemia affecting both the myeloid (ML-DS) and lymphoid (DS-ALL) lineages. ML-DS is associated with a good prognosis compared to children without DS, due in part to a higher sensitivity to conventional chemotherapy.

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.

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.

Children with Down syndrome (constitutive trisomy 21) that develop acute lymphoblastic leukemia (DS-ALL) have a 3-fold increased likelihood of treatment-related mortality coupled with a higher cumulative incidence of relapse, compared with other children with B-cell acute lymphoblastic leukemia (B-ALL).
