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).

You can also talk about this with the Cancer Research UK nurses on freephone 0808 800 4040, from 9am to 5pm, Monday to Friday.

What affects survival?

Survival depends on many factors. It depends on the stage and grade of the NET when it was diagnosed. The stage describes the size of the tumour and whether it has spread. The grade means how abnormal the cells look under a microscope. 

Another factor is how well you are overall.

Types of stomach NET

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.

We have information about the overall survival of people with stomach cancer. Remember to click back to return to the neuroendocrine section.

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.

Almost 75 out of every 100 people (almost 75%) 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.

The Office for National Statistics (ONS) and researchers collect information. They watch what happens to people with cancer in the years after their diagnosis. 5 years is a common time point to measure survival. But some people live much longer than this.

5 year survival is the number of people who have not died from their cancer within 5 years after diagnosis.
