Despite widespread localization in the brain, astroblastoma is rarely reported in oncological studies, accounting for only 0.45–2.8% of all brain gliomas since its discovery in 1926. [ 4 ] [ 5 ] [ 6 ] Without a doubt, astroblastoma remains one of the most challenging and problematic tumors to diagnose and treat among all nervous system cancers.
[4] [5] Currently, the standard of care is fractionated external beam radiotherapy, as the tumour location precludes surgery, and chemotherapy has shown to be ineffective. [6] [7] However, the estimated survival post-diagnosis remains only 9–15 months. DMGs primarily affect children: the median age of diagnosis is around 6-7 years old. [8]

Neuroblastoma is the most common cancer in babies and the third-most common cancer in children after leukemia and brain cancer. [5] About one in every 7,000 children is affected at some time. [2] About 90% of cases occur in children less than 5 years old, and it is rare in adults. [2] [3] Of cancer deaths in children, about 15% are due to ...

Cancer in children is rare in the UK, with an average of 1,800 diagnoses every year but contributing to less than 1% of all cancer-related deaths. [70] Age is not a confounding factor in mortality from the disease in the UK. From 2014 to 2016, approximately 230 children died from cancer, with brain/CNS cancers being the most commonly fatal type.
