Glioblastoma

Glioblastoma (GBM) is a type of malignant brain tumour that is fast-growing and aggressive.

  • Symptoms: Common symptoms of GBM include headache, nausea, vomiting, changes in vision, movement or speech, seizures, and changes in mood, behaviour, or cognitive function (thinking).
  • Diagnosis: A diagnosis of GBM is usually first suspected on a CT and MRI scan of the brain. The diagnosis is confirmed by examination of tissue removed by surgery (biopsy).
  • Treatment: The standard treatment for GBM includes surgery to remove as much of the tumour as is safely possible, followed by radiation therapy and chemotherapy. Sometimes a clinical trial of an experimental treatment may be recommended.
  • Prognosis: GBM is a challenging disease to treat, with most patients surviving only one or two years after diagnosis. However, with advances in treatments, some patients may live longer, and up to 10% of patients may live 5 years.
  • Side effects: Treatment for GBM can cause a variety of side effects, including fatigue, nausea, hair loss, and skin irritation. Surgery may occasionally result in neurological symptoms such as weakness, numbness, speech disturbance or loss of vision.
  • Coping: Living with a GBM can be emotionally and physically challenging, and patients and their family may benefit from support groups, counselling, or other forms of emotional support.
