Glioblastoma prognosis
Glioblastoma prognosis is when your doctor or medical team explains what you might expect from your diagnosis. Here we discuss average glioblastoma prognosis, but your prognosis will depend on things specific to you, such as how well you respond to treatment.
Short summary
Glioblastoma is a an aggressive type of brain tumour. And, the survival time for glioblastoma is sadly short on average. We discuss averages on this page, but please remember that everyone is different and averages can’t say what will happen to you specifically.
We know that glioblastoma prognosis is a sensitive topic and can be difficult to read about. Our Support Team is here if this is worrying or upsetting for you.

About glioblastomas
Glioblastomas (or GBMs) are grade 4 brain tumours. They are the most common high grade primary brain tumour in adults. Primary brain tumours are tumours that begin in the brain as opposed to spreading there.
Treatment for GBMs can include surgery followed by chemotherapy and radiotherapy.
What is a glioblastoma prognosis?
A prognosis is when your doctor tells you what to expect if you have a diagnosis, such as a glioblastoma.
Your doctor can’t be absolutely certain about what will happen to you following a brain tumour diagnosis. But, they can give you an estimate, based on your tumour type and current situation.
There are some things your doctor might not be able to predict, like how well you might respond to treatment. Cancer Research UK have some information about the things that can impact brain tumour survival.
This is why prognosis is often an ongoing process, revised at different stages in your journey.
Glioblastoma survival rate
The average glioblastoma survival time is 12-18 months – only 25% of patients survive more than one year, and only 5% of patients survive more than five years.
The figures listed above are given in 1 and 5-year intervals simply because doctors use these intervals for research/measuring purposes – they are not meant to represent how long a person will live past those intervals. For example, a patient who is a 5-year survivor might live as long as any other healthy person, depending on their circumstances.
Please remember that statistics and averages can’t tell you what will happen to you specifically.

Receiving information about a glioblastoma prognosis
Different people approach their prognosis in different ways.
- Some do not want to know, because they are afraid of what they might hear and how it may affect them
- Some just need some time to cope with their diagnosis before asking about their prognosis
- Others may want to know from the beginning, using their prognosis to plan ahead
There is no right or wrong answer to how or when you receive the news. It’s entirely up to you when, or if, you want to speak to your doctor about your prognosis.
