ON THIS PAGE: You will find information about how many people learn they have 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.
Each year an estimated 8,000 people in the United States are diagnosed with a neuroendocrine tumor that starts in the gastrointestinal tract, which includes the stomach, intestine, appendix, colon, or rectum. The five-year survival rate is the percentage of people who survive at least five years after the tumor is detected, excluding those who die from other diseases. The five-year survival rate of people with neuroendocrine tumors varies and depends on several factors. Check the section for the specific type of neuroendocrine tumor (see the Overview  section) for more information.
More than 1,500 people in the United States are diagnosed with Merkel cell cancer each year. The five-year survival rate of people with Merkel cell cancer is about 60%. It is much higher if the cancer is found early, before it has spread to the lymph nodes or distant parts of the body.
Survival statistics should be interpreted with caution. These estimates are based on data from thousands of people with this type of tumor, but the actual risk for a particular individual may differ. It is not possible to tell a person how long he or she will live with a neuroendocrine tumor. Because the survival statistics are measured in five-year intervals, they may not represent advances made in the treatment or diagnosis of this tumor. Learn more about understanding statistics .
