Medulloblastoma is the second-most frequent brain tumor in children after pilocytic astrocytoma [37] and the most common malignant brain tumor in children, comprising 14.5% of newly diagnosed brain tumors. [38] In adults, medulloblastoma is rare, comprising fewer than 2% of CNS malignancies. [39]
Brain tumors are the most common type of solid tumors to affect the pediatric population. [ 3 ] In particular, medulloblastoma is the most common of them, and constitutes about 20% of all the malignant pediatric brain tumors, classified as a primitive neuroectodermal tumor (PNET) of the cerebellum.
Primitive neuroectodermal tumor is a malignant (cancerous) neural crest tumor. [1] It is a rare tumor , usually occurring in children and young adults under 25 years of age. The overall 5 year survival rate is about 53%.

Pleomorphic xanthoastrocytoma (PXA) is a brain tumor that occurs most frequently in children and teenagers. At Boston Children's Hospital, the average age at diagnosis is 12 years. [1] Pleomorphic xanthoastrocytoma usually develops within the supratentorial region (the area of the brain located above the tentorium cerebelli).
It mostly affects children ages 5 to 9 and can spread to other parts of the central nervous system and spinal cord, according to the Preston Robert Tisch Brain Tumor Center at Duke. (Doctors at ...
An estimated 3% of pediatric brain tumors are AT/RTs, although this percentage may increase with better differentiation between PNET/medulloblastoma tumors and AT/RTs. [citation needed] As with other CNS tumors, more males are affected than females (ratio 1.6:1). The ASCO study showed a 1.4:1 male to female ratio. [3]
In children aged 0–14 years, the most common brain tumors are pilocytic astrocytomas (17.5%), embryonal tumors (15.7%), and malignant gliomas (25.7%). [15] The overall incidence rate of brain tumors in children is 6.2 per 100,000. [9] The distribution and behavior of nervous system neoplasms differ significantly between adults and children.
