Islet cell tumors are uncommon, with about 1,000 people diagnosed each year in the United States. Islet cell tumors account for about 3% to 5% of all pancreatic cancers.

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.

In general, the 5-year survival rate of people with an islet cell tumor is about 42%. However, the survival rate depends on a variety of factors, including whether the tumor can be removed using surgery. If a tumor is localized and can be removed, the 5-year survival rate is about 55%. If a tumor cannot be removed, the 5-year survival rate is about 15%. 

It is important to remember that statistics on how many people survive this type of cancer are an estimate. The estimate comes from data based on people with this cancer in the United States each year. So, your own risk may be different. Doctors cannot say for sure how long anyone will live with an islet cell tumor. Also, experts measure the survival statistics every 5 years. This means that the estimate may not show the results of better diagnosis or treatment available for less than 5 years. Learn more about understanding statistics.
