Neuroendocrine Tumor of the Gastrointestinal Tract: Statistics

Approved by the Cancer.Net Editorial Board, 01/2019

ON THIS PAGE: You will find information about the number of people who are diagnosed with a GI tract NET each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.

As explained in the Introduction, NETs often develop in the GI tract. The number of diagnosed NETs has been increasing by more than 5% per year, but the reason why is unknown.

Each year, about 8,000 adults in the United States are diagnosed with a GI tract NET. The most common place in the GI tract for this type of tumor is the small intestine and the rectum. 

The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. However, the survival rate depends on many factors, including the location of the tumor.

The 5-year survival rate for people with a GI tract NET that has not spread to other parts of the body is 98%, depending on the stage and location of the tumor. If the tumor has spread to nearby tissue or the regional lymph nodes, the 5-year survival rate is 93%. If the tumor has spread to distant areas of the body, the survival rate is 67%.

It is important to remember that statistics on the survival rates for people with a GI tract NET are an estimate. The estimate comes from annual data based on the number of people with this cancer in the United States. Also, experts measure the survival statistics every 5 years. So, the estimate may not show the results of better diagnosis or treatment available for less than 5 years. Talk with your doctor if you have any questions about this information.
