Cancer Stat Facts: Small Intestine Cancer
Statistics at a GlanceShow More
At a Glance
- Estimated New Cases in 2017 10,190
- Estimated Deaths in 2017 1,390
Number of New Cases and Deaths per 100,000: The number of new cases of small intestine cancer was 2.3 per 100,000 men and women per year. The number of deaths was 0.4 per 100,000 men and women per year. These rates are age-adjusted and based on 2010-2014 cases and deaths.
Lifetime Risk of Developing Cancer: Approximately 0.3 percent of men and women will be diagnosed with small intestine cancer at some point during their lifetime, based on 2012-2014 data.
Survival StatisticsShow More
How Many People Survive 5 Years Or More after Being Diagnosed with Small Intestine Cancer?
Relative survival 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 2007-2013. Gray figures represent those who have died from small intestine cancer. Green figures represent those who have survived 5 years or more.
Survival by Stage
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 small intestine cancer is caught, the better chance a person has of surviving five years after being diagnosed. For small intestine cancer, 31.7% are diagnosed at the local stage. The 5-year survival for localized small intestine cancer is 85.3%.
- Localized (32%)
Confined to Primary Site
- Regional (35%)
Spread to Regional Lymph Nodes
- Distant (27%)

|23.||Small Intestine Cancer||10,190||1,390|
Small intestine cancer represents 0.6% of all new cancer cases in the U.S.
In 2017, it is estimated that there will be 10,190 new cases of small intestine cancer and an estimated 1,390 people will die of this disease.
Who Gets This Cancer?
Cancer of the small intestine is slightly more common among men than women. Diet and health history can affect the risk of developing this cancer. The number of new cases of small intestine cancer was 2.3 per 100,000 men and women per year based on 2010-2014 cases.
Small intestine 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 small intestine cancer cases have been rising on average 2.3% each year over the last 10 years. Death rates have been stable over 2005-2014. 5-year survival trends are shown below the figure.

Cancer and the Small Intestine
This cancer forms in tissues of the small intestine (the part of the digestive tract between the stomach and the large intestine). The most common type is adenocarcinoma (cancer that begins in cells that make and release mucus and other fluids). Other types of small intestine cancer include sarcoma (cancer that begins in connective or supportive tissue), carcinoid tumor (a slow-growing type of cancer), gastrointestinal stromal tumor (a type of soft tissue sarcoma), and lymphoma (cancer that begins in immune system cells).

These stat facts focus on population statistics that are based on the US population. Because these statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. To see tailored statistics, browse the SEER Cancer Statistics Review. To see statistics for a specific state, go to the State Cancer Profiles.
The statistics presented in these stat facts 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. These stat facts do not address causes, symptoms, diagnosis, treatment, follow-up care, or decision making, although links are provided to information in many of these areas.
