Brain Tumour Awareness Month 2023: Where Are We Now?

Brain Tumour Awareness Month 2023: Where Are We Now?

Did you know brain tumours kill more children and adults under the age of 40 than any other cancer? [1].

It is estimated that around 88,000 children and adults are living with a brain tumour in the UK and sadly only about 12% of adults survive for 5 years after diagnosis [1]. Brain tumours reduce life expectancy by an average of 27 years – the highest of any cancer - yet only 3% of cancer research funding in the UK is spent on brain tumours [1].

There have only been marginal improvements in the treatment and prognosis of brain tumors over the past decade [2]. Urgent awareness and an increase in research funding is needed to give people affected more time and a better quality of life.

In this blog we will cover:

• Signs and symptoms
• Diagnosis
• Treatment
• Help and support

Signs and symptoms

Brain tumours can cause a variety of symptoms but the most common are [3]:

• Headaches, caused by pressure created in the skull by the brain tumour
• Changes in vision, resulting from compression of the optic nerve
• Seizures, caused by the brain tumour affecting normal brain activity
• Nausea and dizziness
• Tiredness
• Loss of taste and smell
• Cognitive changes such as difficulties with memory or personality changes
• Communication problems such as speech that is slurred, slow or difficult to understand

If you think you have any of the symptoms listed above and you are concerned, contact your GP straight away.

Diagnosis

Often patients are initially examined by a GP who will refer to a neurologist if they suspect a brain tumour. The neurologist will perform neurological and ophthalmic examinations followed by advanced imaging of the brain in the form of Computerised Tomography and/or Magnetic Resonance Imaging. A surgical biopsy is sometimes taken via a burr hole into the skull for tumour diagnosis and grading [4].

Treatment

Conventional brain tumour treatments

Conventional treatments consist of neurosurgery, radiotherapy and stereotactic radiotherapy, chemotherapy, and steroids [4]. However, the type of treatment will depend on many factors such as tumour type, location, and the individual patient. Also, treatments can differ slightly between adults and children.

Non-conventional brain tumour treatments

There are clinical trials all around the world testing non-conventional, innovative treatments and delivery systems to try and improve the lives of people living with a brain tumour. Further information about the clinical trials currently available can be found by accessing the following links below.

• BRIAN - an app developed by The Brain Tumour Charity which includes a clinical trial finder (www.thebraintumourcharity.org).
• ClinicalTrials.gov - a database of privately and publicly funded clinical studies conducted around the world (www.www.clinicaltrials.gov ).
• Cancer Research UK - a database for UK clinical trials (www.cancerresearchuk.org/about-cancer/find-a-clinical-trial).

Emerging treatments

There are also a number of emerging treatments that are currently being developed [1]:

• BrainPath? - a novel surgical technique that uses the natural folds of the brain to create a channel to the tumour site.
• Convection Enhanced Delivery (CED) - delivering chemotherapy drugs directly into the brain tumour.
• ?Tumour Treating Fields (TTF) - a non-invasive electrical field treatment for glioblastoma.
• Dendritic Cell Therapy (DCT) - a type of immunotherapy.
