Pediatric Glioblastoma

Glioblastomas (GBM) are tumors in the brain or spinal cord that are usually highly malignant (cancerous)

What is Pediatric Glioblastoma?

Glioblastomas (GBM) are tumors that develop from astrocytes (star-shaped cells that comprise the supportive tissue) of the brain. Because GBM cells reproduce rapidly and are supported by a large network of blood vessels, they are usually cancerous. GBM tumors put extra pressure on the brain, causing the related symptoms.

What are the different types of Pediatric Glioblastoma?

There are two types of GBM:

Primary (de novo)

Primary (de novo) – The most common type of GBM, this type usually forms quickly and children rapidly begin to show symptoms.


Secondary – This type of GBM usually grows more slowly, but is still quite aggressive. In many cases, they begin as low-grade tumors (slow rate of growth and high rate of survival) that turn into a higher grade over time.

What are the signs and symptoms of Pediatric Glioblastoma?

Signs and symptoms of GBM can include:
  • Changes in vision
  • Drowsiness
  • Headache
  • Nausea
  • Problems with memory
  • Problems with speech
  • Vomiting
  • Weakness on one side of the body
