Long-term outcomes of symptomatic optic pathway glioma: 32-year experience at a single Western Australian tertiary pediatric oncology centerOptic pathway gliomas (OPGs) are associated with significant risk of visual and endocrine morbidity, but data on long-term outcomes in symptomatic patients is sparse. This study reviews the clinical course, disease progression, survival outcomes and long-term sequelae in pediatric patients with symptomatic OPGs in our institution over three decades.

Identification of fatty acid amide hydrolase as a metastasis suppressor in breast cancerClinical management of breast cancer (BC) metastasis remains an unmet need as it accounts for 90% of BC-associated mortality. Although the luminal subtype, which represents >70% of BC cases, is generally associated with a favorable outcome, it is susceptible to metastatic relapse as late as 15 years after treatment discontinuation.

A multi-institutional retrospective pooled outcome analysis of molecularly annotated pediatric supratentorial ZFTA-fused ependymomaZFTA-RELA (formerly known as c11orf-RELA) fused supratentorial ependymoma has been recognized as a novel entity in the 2016 WHO classification of CNS tumors and further defined in the recent 2021 edition.

ONC201 in Combination with Paxalisib for the Treatment of H3K27-Altered Diffuse Midline GliomaDiffuse midline gliomas (DMG), including diffuse intrinsic pontine gliomas (DIPG), are the most lethal of childhood cancers. Palliative radiotherapy is the only established treatment, with median patient survival of 9 to 11 months. ONC201 is a DRD2 antagonist and ClpP agonist that has shown preclinical and emerging clinical efficacy in DMG.Â

A novel transcriptional signature identifies T-cell infiltration in high-risk paediatric cancerMolecular profiling of the tumour immune microenvironment (TIME) has enabled the rational choice of immunotherapies in some adult cancers. In contrast, the TIME of paediatric cancers is relatively unexplored. We speculated that a more refined appreciation of the TIME in childhood cancers, rather than a reliance on commonly used biomarkers such as tumour mutation burden (TMB), neoantigen load and PD-L1 expression, is an essential prerequisite for improved immunotherapies in childhood solid cancers.

National brain tumour registry: a new era of research collaboration with ChinaCancer continues to be a leading cause of death globally. However, there remains a significant disparity in the reported incidence of cancer in developed countries, estimated to be 295.3 cases per 100,000 people, compared with only 115.7 in developing countries. Some of the reasons for this variation include lack of robust data collection with limited reporting systems, and insufficient data availability in the registries of these developing nations.

Multiomic neuropathology improves diagnostic accuracy in pediatric neuro-oncologyThe 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.

Activation of Hedgehog signaling by the oncogenic RELA fusion reveals a primary cilia-dependent vulnerability in supratentorial ependymomaSupratentorial 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.

Fathers’ Experiences of Childhood Cancer: A Phenomenological Qualitative StudyResearch has shown differences in how fathers and mothers respond to a child's cancer diagnosis. Previous studies have highlighted that sociocultural norm shape fathers' experiences of their child's cancer diagnosis. Our phenomenological qualitative study aimed to examine the lived experiences of fathers whose children have been diagnosed with cancer and explore the impact of sociocultural gender roles.

Acute Leukaemia of Ambiguous Lineage Presenting as a Focal Bone Lesion: a Case ReportAcute leukaemia is the most common childhood malignancy. Almost all cases are classified as acute lymphoblastic leukaemia or acute myeloid leukaemia. Acute leukaemia of ambiguous lineage (ALAL) is a rare form of acute leukaemia that cannot be classified by a single lineage. Like other acute leukaemias, ALAL typically presents with nonspecific symptoms such as fatigue, fever, or bleeding.
