Verschlimmbesserung: Craniospinal Radiotherapy Is Essential in WNT Medulloblastoma PatientsStandard-risk WNT medulloblastoma patients have an excellent prognosis using the combination of standard dose craniospinal radiotherapy (CSI) followed by platinum and alkylator based chemotherapy. A recent pilot study that attempted to completely omit radiotherapy was terminated early as all patients relapsed rapidly. The study highlights that therapy is the most important prognostic factor, with CSI still required to cure even the most favorable subgroup of medulloblastoma patients.

Presence of onco-fetal neighborhoods in hepatocellular carcinoma is associated with relapse and response to immunotherapyOnco-fetal reprogramming of the tumor ecosystem induces fetal developmental signatures in the tumor microenvironment, leading to immunosuppressive features. Here, we employed single-cell RNA sequencing, spatial transcriptomics and bulk RNA sequencing to delineate specific cell subsets involved in hepatocellular carcinoma relapse and response to immunotherapy.

Intravascular Tumor Extension and Pulmonary Tumor Embolism in Children With Solid Malignancies: Is There a Role for Inferior Vena Cava Filters?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.

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.
Associate Professor Lesterhuis said the gel, developed with the help of chemists at The University of Western Australia, could revolutionise the way solid tumours were treated.

Efficacy of DYRK1A inhibitors in novel models of Down syndrome acute lymphoblastic leukemiaDespite significant advances, outcomes for children with Down syndrome (DS, trisomy 21) who develop acute lymphoblastic leukemia remain poor. Reports of large DS-ALL cohorts have shown that children with DS have inferior event-free survival and overall survival compared to children without DS.

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 StudyDNA 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.

BRAF-mediated brain tumors in adults and children: A review and the Australian and New Zealand experienceThe mitogen-activated protein kinase (MAPK) pathway signaling pathway is one of the most commonly mutated pathways in human cancers. In particular, BRAF alterations result in constitutive activation of the rapidly accelerating fibrosarcoma-extracellular signal-regulated kinase-MAPK significant pathway, leading to cellular proliferation, survival, and dedifferentiation.

Delivery of PEGylated liposomal doxorubicin by bispecific antibodies improves treatment in models of high-risk childhood leukemiaHigh-risk childhood leukemia has a poor prognosis because of treatment failure and toxic side effects of therapy. Drug encapsulation into liposomal nanocarriers has shown clinical success at improving biodistribution and tolerability of chemotherapy. However, enhancements in drug efficacy have been limited because of a lack of selectivity of the liposomal formulations for the cancer cells.

EphA3-targeted chimeric antigen receptor T cells are effective in glioma and generate curative memory T cell responsesHigh-grade gliomas including glioblastoma (GBM) and diffuse midline gliomas (DMG) represent the most lethal and aggressive brain cancers where current treatment modalities offer limited efficacy. Chimeric antigen receptor (CAR) T cell therapies have emerged as a promising strategy, boasting tumor-specific targeting and the unique ability to penetrate the blood-brain barrier.
