Survival depends on many different factors. It depends on your individual condition, type of neuroendocrine tumour (NET), treatment and level of fitness. So no one can tell you exactly how long you will live.
These are general statistics based on large groups of people. Remember, they can’t tell you what will happen in your individual case.
Your doctor can give you more information about your own outlook (prognosis).
There are 3 types of stomach NETs:
- type 1 (this is the most common type)
- type 2
- type 3
Where this information comes from
In the UK, no statistics are available for the survival of the different types of stomach NETs. The statistics presented here are international and might not accurately reflect UK statistics. They are gathered from various sources, including the opinions and experience of the experts who check our information.

Survival for all types of stomach NET
These statistics are from an American study, looking at people diagnosed between 2004 to 2013.
Please be aware that due to differences in health care systems, data collection and the population these studies are not an accurate picture of survival in the UK.
Around 73 out of every 100 people (around 73%) survive for 5 years or more.
Survival for type 1 stomach NETs
Almost 100 out of 100 people (almost 100%) with a type 1 stomach neuroendocrine tumour survive for 5 years or more.
Survival for type 2 stomach NETs
Between 60 and 75 out of 100 people (between 60 and 75%) with a type 2 stomach neuroendocrine tumour survive for 5 years or more.
Survival for type 3 stomach NETs
75 out of 100 people (75%) who have a type 3 stomach NET, and have had extensive surgery to remove the tumour, survive for 5 years or more.
Stomach NETs that have spread to a distant part of the body can be more difficult to treat.
About these statistics
The terms 1 year survival and 5 year survival don't mean that you will only live for 1 or 5 years. They relate to the number of people who are still alive 1 year or 5 years after their diagnosis of cancer.
Some people live much longer than 5 years.
