Prevalence of this cancer: In 2011, there were an estimated 74,035 people living with stomach cancer in the United States.

Survival StatisticsShow More

How Many People Survive 5 Years Or More after Being Diagnosed with Stomach Cancer?

Relative survivalExternal Web Site Policy statistics compare the survival of patients diagnosed with cancer with the survival of people in the general population who are the same age, race, and sex and who have not been diagnosed with cancer. Because survival statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. No two patients are entirely alike, and treatment and responses to treatment can vary greatly.

Based on data from SEER 18 2004-2010. Gray figures represent those who have died from stomach cancer. Green figures represent those who have survived 5 years or more.

Additional Information

Cancer stage at diagnosis, which refers to extent of a cancer in the body, determines treatment options and has a strong influence on the length of survival. In general, if the cancer is found only in the part of the body where it started it is localized (sometimes referred to as stage 1). If it has spread to a different part of the body, the stage is regional or distant. The earlier stomach cancer is caught, the better chance a person has of surviving five years after being diagnosed. For stomach cancer, 25.7% are diagnosed at the local stage. The 5-year survival for localized stomach cancer is 64.1%.

Stomach cancer represents 1.3% of all new cancer cases in the U.S.

1.3%

In 2014, it is estimated that there will be 22,220 new cases of stomach cancer and an estimated 10,990 people will die of this disease.

Stomach cancer is more common in men than women and among other races and ethnicities than non-Hispanic whites. Age, diet and stomach disease, including infection with Helicobacter pylori can affect the risk of developing stomach cancer. The number of new cases of stomach cancer was 7.5 per 100,000 men and women per year based on 2007-2011 cases.

Percent of New Cases by Age Group: Stomach Cancer
0.1% under 20; 1.7% 20-34; 4.5% 35-44; 12.2% 45-54; 20.4% 55-64; 24.7% 65-74; 24.3% 75-84; 12.2% 85 and older

Stomach cancer is most frequently diagnosed among people aged 65-74.

Changes Over Time

Keeping track of the number of new cases, deaths, and survival over time (trends) can help scientists understand whether progress is being made and where additional research is needed to address challenges, such as improving screening or finding better treatments.

Using statistical models for analysis, rates for new stomach cancer cases have been falling on average 1.5% each year over the last 10 years. Death rates have been falling on average 3.0% each year over 2002-2011. 5-year survival trends are shown below the figure.

Cancer and the Stomach

Click to enlarge.

The wall of the stomach is made up of 3 layers of tissue: the mucosal (innermost) layer, the muscularis (middle) layer, and the serosalExternal Web Site Policy (outermost) layer. Gastric cancer begins in the cells lining the mucosal layer and spreads through the outer layers as it grows.

Stromal tumors of the stomach begin in supporting connective tissue and are treated differently from gastric cancer. See the PDQExternal Web Site Policy summary on Gastrointestinal Stromal Tumors TreatmentExternal Web Site Policy for more information.

The statistics presented in this factsheet are based on the most recent data available, most of which can be found in the SEER Cancer Statistics Review. In some cases, different year spans may be used. Estimates for the current year are based on past data.

Cancer is a complex topic. There is a wide range of information available. This factsheet does not address causes, symptoms, diagnosis, treatment, follow-up care, or decision making, although it provides links to information in many of these areas.
