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.
Over 90% of US children with cancer are treated at Children's Oncology Group (COG) centers, which seek to maximize enrollment in therapeutic and biobanking studies. Rare cancers have demonstrated lower than expected COG enrollment. We evaluated trends in COG rare cancer enrollment compared to US incidence from Surveillance, Epidemiology, and End Results (SEER) registries, examining the impact of COG therapeutic trials and Project:EveryChild, a cancer biobank/registry.
Childhood cancer survivors (CCS) are at risk of long-term skeletal muscle deficits following intensive therapies during critical periods of growth. This review aimed to synthesize approaches for assessing muscle quantity, quality, and function in CCS and to quantify deficits relative to healthy peers.
Current immunization guidelines recommend one dose of influenza vaccine for children aged ≥9 years and two doses for younger or vaccine-naïve children. However, children receiving chemotherapy have an attenuated immune response. We performed a prospective open-label study in children undergoing treatment for cancer at Perth Children's Hospital, Western Australia, to examine the safety and efficacy of a boosted influenza schedule.
Smokers are at an increased risk of developing mucosal head and neck squamous cell cancers (HNSCCs) and have a worse prognosis when treated. The cellular and molecular mechanisms underlying the latter has not been established. We therefore developed an in vitro model to investigate the effects of radiation and smoking on mucosal HNSCCs.

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.
Supratentorial RELA fusion (ST-RELA) ependymomas (EPNs) are resistant tumors without an approved chemotherapeutic treatment. Unfortunately, the molecular mechanisms that lead to chemoresistance traits of ST-RELA remain elusive. The aim of this study was to assess RELA fusion-dependent signaling modules, specifically the role of the Hedgehog (Hh) pathway as a novel targetable vulnerability in ST-RELA.
The large diversity of central nervous system (CNS) tumor types in children and adolescents results in disparate patient outcomes and renders accurate diagnosis challenging. In this study, we prospectively integrated DNA methylation profiling and targeted gene panel sequencing with blinded neuropathological reference diagnostics for a population-based cohort of more than 1,200 newly diagnosed pediatric patients with CNS tumors, to assess their utility in routine neuropathology.
Intravascular tumor extension is an uncommon complication of solid malignancies that, when present in the inferior vena cava (IVC), can result in fatal pulmonary tumor embolism. Currently, neoadjuvant chemotherapy and surgery are the mainstays of treatment; however, there are no consensus guidelines for management.
