Astrocytoma prognosis

A prognosis is when your doctor gives you a forecast of the likely outcome of your medical condition. We know that it can be difficult to read about the astrocytoma prognosis, so our Support team is here if this is worrying or upsetting for you.

Your doctor cannot be absolutely certain about what will happen to you following a diagnosis of a brain tumour. They can give you an estimate, based on your tumour type and current situation, but they may not be able to predict other factors, such as how well you might respond to treatment. This is why prognosis is often an ongoing process, revised at different stages in your journey.

Cancer Research UK have some information about the factors which may impact brain tumour survival here

Astrocytoma survival

Low grade (grade 2)

The average survival time after surgery is 6 – 8 years. More than 40% of people live more than 10 years.

High grade (grade 3)

About 27% of people diagnosed with a high grade astrocytoma live for five years or more.

Astrocytoma (Grade 1 and 2) child survival rates

Almost 90% of children survive for 5 years or more after surgery.

Grade 4 – Glioblastoma 

A grade 4 astrocytoma is called a glioblastoma. The average survival time is 12-18 months – only 25% of glioblastoma patients survive more than one year, and only 5% of patients survive more than five years.

The figures listed above for astrocytoma survival are given in 1, 2, 5 and 10 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.

It is important to remember that statistics and averages cannot tell you what will happen to you specifically.
