A long-term analysis of nearly 160,000 US postmenopausal women found that brain and central nervous system cancer risk increased with higher residential radon concentrations, adding to limited evidence that radon may affect organs beyond the lung.

Gliomas and ependymomas appear to reuse developmental hierarchies, progenitor states, and neural-circuit signals that shape tumor heterogeneity and treatment response, although many proposed therapeutic vulnerabilities remain supported primarily by preclinical evidence.

A phase 3 randomized trial of 449 children with intracranial ependymoma found no significant event-free or overall survival benefit from adding maintenance chemotherapy after radiation, while molecular markers — particularly 1q gain and 6q loss — identified a high-risk posterior fossa subgroup with substantially worse outcomes.

The findings provide significant conceptual advances into cancer neuroscience and establish therapeutic avenues that are distinct from present amyloid-lowering strategies, aiming at degrading the existing amyloid plaques.

“Although historically grouped together, viral-associated PCNSL subtypes are biologically distinct diseases. Each escapes immune control through a different mechanism, creating fundamentally different tumor microenvironments.” – Melinda Burgess, Researcher from the Department of Haematology at Princess Alexandra Hospital

In neuro-oncology, where many of the therapies are expensive, toxic, and difficult to access, the idea that a low-cost, generic medication might help slow a tumor like glioblastoma is extremely attractive.
