In vivo loss of tumorigenicity in a patient-derived orthotopic xenograft mouse model of ependymoma

Ependymomas (EPN) are the third most common malignant brain cancer in children. Treatment strategies for pediatric EPN have remained unchanged over recent decades, with 10-year survival rates stagnating at just 67% for children aged 0-14 years. Moreover, a proportion of patients who survive treatment often suffer long-term neurological side effects as a result of therapy. It is evident that there is a need for safer, more effective treatments for pediatric EPN patients.

Implementation of DNA Methylation Array Profiling in Pediatric Central Nervous System Tumors: The AIM BRAIN Project: An Australian and New Zealand Children's Haematology/Oncology Group Study

DNA methylation array profiling for classifying pediatric central nervous system (CNS) tumors is a valuable adjunct to histopathology. However, unbiased prospective and interlaboratory validation studies have been lacking. The AIM BRAIN diagnostic trial involving 11 pediatric cancer centers in Australia and New Zealand.

PI3K/mTOR is a therapeutically targetable genetic dependency in diffuse intrinsic pontine glioma

Diffuse midline glioma (DMG), including tumors diagnosed in the brainstem (diffuse intrinsic pontine glioma; DIPG), are uniformly fatal brain tumors that lack effective treatment.

Patient-Derived Orthotopic Xenograft Models for High-Grade Pediatric Brain Cancers

Patient-derived orthotopic xenograft (PDOX) mouse models are considered the gold standard for evidence-based preclinical research in pediatric neuro-oncology. This protocol describes the generation of PDOX models by intracranial implantation of human pediatric brain cancer cells into immune-deficient mice, and their continued propagation to establish cohorts of animals for preclinical research.

Management of patients with diffuse intrinsic pontine glioma in Australia and New Zealand: Australian and New Zealand Children's Haematology/Oncology Group position statement

The main mission of the Australian and New Zealand Children's Haematology and Oncology Group is to develop and facilitate local access to the world's leading evidence-based clinical trials for all paediatric cancers, including brain tumours, as soon as practically possible. 

Irreversible growth plate fusions in children with medulloblastoma treated with a targeted hedgehog pathway inhibitor

We report on 3 children treated with vismodegib who developed widespread growth plate fusions that persist long after cessation of therapy.

A Pre-Clinical Assessment of the Pan-ERBB Inhibitor Dacomitinib in Pediatric and Adult Brain Tumors

Glioblastoma in adults, and medulloblastoma and pineoblastoma that mainly affect children, are aggressive brain tumors.

The case for DNA methylation based molecular profiling to improve diagnostic accuracy for central nervous system embryonal tumors (not otherwise specified) in adults

We report the case of a 45-year-old woman who was diagnosed with a NOS based on immunohistochemical analysis of the patient's tumor at diagnosis.

Unusual paediatric spinal myxopapillary ependymomas: Unique molecular entities or pathological variations on a theme?

We describe two unusual cases of MPE and use DNA methylation analyses to compare their signatures to try and distinguish if these represent a unique subset.

Activation of ERBB4 in Glioblastoma Can Contribute to Increased Tumorigenicity and Influence Therapeutic Response

The functional effects of increased ERBB4 activation identify ERBB4 as a potential prognostic and therapeutic target
