Overview
If left untreated, glioblastoma multiforme may extend into the meninges, ventricular wall, or spinal cord. Common complications of glioblastoma multiforme include herniation, hydrocephalus, systemic illness, brainstem invasion by tumor, neutron-induced cerebral injury, weakness, fatigue, numbness, surgical complications, and coma.[1] Prognosis is generally poor, and the 5-year survival rate of patients with glioblastoma multiforme is less than 10%.
Natural History
- Glioblastoma multiforme usually form in the cerebral white matter, grow quickly, and can become very large before producing symptoms. Less than 10% grow slowly following degeneration of low-grade astrocytoma or anaplastic astrocytoma.
- It may extend into the meninges or ventricular wall, leading to high protein content in the cerebrospinal fluid.
- The tumor cells carried in the CSF may rarely spread to the spinal cord. However, metastasis of glioblastoma multiforme beyond the central nervous system is rare. About 50% of glioblastoma multiforme are bilateral.
- It arises from the cerebrum and may rarely exhibit the classic infiltration across the corpus callosum, producing a butterfly (bilateral) glioma.
Complications
Common complications of glioblastoma multiforme include:[1]
- Herniation (axial, transtentorial, subfalcine, tonsillar)
- Hydrocephalus
- Systemic illness
- Brainstem invasion by tumor
- Neutron-induced cerebral injury
- Weakness
- Fatigue
- Numbness
- Surgical complications (cerebral hemorrhage, edema)
- Coma
