What is Glioblastoma Multiforme?
Glioblastoma multiforme is a form of cancer in which the brain cells start to divide rapidly and uncontrollably, creating a malignant tumour. These cells are also very good at escaping the site of the original tumour and migrating to other parts of the brain, where they start the process all over again.
Why is Glioblastoma so difficult to treat?
Glioblastoma is very aggressive; and its effect is to cause chaos in the brain. As it works its way through the brain it develops different characteristics depending on the new locations. Drug penetration varies depending on the density of the tissue and the interaction between the cancer cells with blood vessels and surrounding tissue, and is also impeded by the blood-brain barrier.
What is the blood-brain barrier?
The brain naturally protects itself from the entry of toxins by not allowing ‘foreign’ or ‘large’ elements through via the bloodstream. Unfortunately this means that the brain itself prevents medicinal drugs given orally or intravenously entering in large enough quantities to even begin to tackle glioblastoma.
Why does Glioblastoma affect young people?
No one knows! It may be that the brain is still developing (it continues to mature in physiological terms up to the age of around 25 years). What is known is that if a child under the age of 3 is diagnosed with a brain tumour survival rates are up to 60%, while over the age of 3 the prognosis is much bleaker. The plasticity of the brain as it develops during adolescence means that enormous changes are taking place. Teenage growth is fast, and cancer cells grow fast at the same time. Because of these change, any treatment for glioblastoma becomes even more challenging. Glioblastoma kills 5,000 people under the age of 40 in the UK every year.
What current treatment is there for Glioblastoma?
Current treatment includes surgery, although it is hardly ever possible to remove glioblastoma cells completely, and radiotherapy. Chemotherapy is largely ineffectual, provides minimal benefit and can be highly toxic in terms of its effect on the patient’s quality of life. After diagnosis current treatment is designed to minimise the symptoms for as long as possible and to provide effective pain relief.
What are the symptoms of Glioblastoma?
Because glioblastoma is relatively rare, it is often missed. However, a combination of any two or more of these symptoms should always lead to glioblastoma being considered:
- morning headache relieved by vomiting
- unexplained deterioration in school performance or behaviour
- double or blurred vision
- seizures not necessarily accompanied by a raised temperature
How is Glioblastoma diagnosed?
An in-depth neurological examination will take place, plus either a CT (computed tomography) brain scan, or an MRI (Magnetic Resonance Imaging) brain scan. CT uses specialised x-ray techniques to obtain pictures of the tumour, while MRI uses magnetism instead of x-ray to obtain the pictures. Depending on the location of the tumour within the brain a biopsy (surgical removal of a small sample of tumour tissue) may also take place.
Why is it taking so long to find a cure for Glioblastoma?
There are several reasons:
- brain cancer in general only receives 1% of UK research funding annually
- because glioblastoma is so rare there is no statistically significant data
- lack of statistically significant data means there is no evidence of cost-effectiveness for any current forms of treatment
In our view, all these factors combine to create a vicious circle in which there is no cure for glioblastoma, and there is little treatment because there is no cure!
How will supporting Charlotte’s BAG help the fight?
Charlotte’s BAG is currently funding scientific research, based at Charlotte’s Lab in the neuropathology department at King’s College Hospital, London. The work involves close collaboration with the neurosurgeons and oncologists – individual patients’ tumours are analysed in depth to establish their genetic and molecular structure so that treatment can be tailored individually for a longer, better quality life.
How much money does Charlotte’s BAG need to raise?
We are now in 2021 and so far we have raised £225,000 thanks to the generosity of people all over the world, we have funded a five-year scientific research position at Charlotte’s Lab.
So if you feel the urge to take part in a triathlon or a marathon (!) and want to support us we’d recommend justgiving for your social media campaign; or if you want to divert some of your ebay sales to Charlotte’s BAG you can be sure that we do pretty well out of paypal!
