Survival rates for stomach cancer by stage

Some people with cancer may want to know the survival rates for their type of cancer. Others may not find the numbers helpful, or may even not want to know them. If you do not want to read about the survival statistics for stomach cancer, stop reading here and skip to the next section

The 5-year survival rate refers to the percentage of patients who live at least 5 years after their cancer is diagnosed. Of course, many of these people live much longer than 5 years (and many are cured).

To get 5-year survival rates, doctors have to look at people who were treated at least 5 years ago. Better treatments since then may result in a better outlook for people now found with stomach cancer.

The rates below are based on the stage of the cancer at the time the cancer is found. When looking at survival rates, it’s important to understand that the stage of a cancer does not change over time, even if the cancer grows or spreads.

The 5-year survival rates by stage for stomach cancer treated with surgery are as follows*:

    Stage IA


    Stage IB


    Stage IIA


    Stage IIB


    Stage IIIA


    Stage IIIB


    Stage IIIC


    Stage IV


*The survival rates above come from the National Cancer Institute’s SEER database. They are based on people diagnosed with stomach cancer and treated with surgery between 1991 and 2000. Survival rates for patients not treated with surgery are likely to be lower.

The 5-year relative survival rate compares the number of people who are still alive 5 years after their cancer was found to the survival of others the same age who don’t have cancer. Since some people may die from other causes, this is a better way to see the impact that cancer can have on survival.

The overall 5-year relative survival rate of people with stomach cancer in the United States is about 27%. One reason for this is that most stomach cancers are found at an advanced stage.

Each person is different

While numbers provide an overall picture, keep in mind that every person’s situation is unique and there is no way to predict exactly what will happen in your case. Talk with your cancer care team if you have questions about your personal chances of a cure, or how long you might survive your cancer. They know your situation best.
