Islet Cell Tumor: Statistics

Approved by the Cancer.Net Editorial Board, 06/2015

ON THIS PAGE: You will find information about how many people are diagnosed with this type of tumor each year and some general survival information. Remember, survival rates depend on several factors. To see other pages, use the menu on the side of your screen.

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

The five-year survival rate is the percentage of people who survive at least five years after the tumor is found. The five-year survival rate of people with an islet cell tumor is about 42%. 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 five-year survival rate is about 55%. If a tumor cannot be removed, the five-year survival rate is about 15%. 

Cancer survival statistics should be interpreted with caution. Estimates are based on data from many cases of this type of tumor in the United States each year, so the actual risk for a particular individual may be different. It is not possible to tell a person how long he or she will live with an islet cell tumor. Learn more about understanding statistics.
