Survival Rates of Small Intestine Adenocarcinoma, by Stage

Survival rates are often used by doctors as a standard way of discussing a person’s prognosis (outlook). Some patients with cancer may want to know the survival statistics for people in similar situations, while others may not find the numbers helpful, or may even not want to know them. If you decide that you don’t want to read them, skip to the next section.

The 5-year survival rate is the percentage of patients who live at least 5 years after their cancer is diagnosed. Of course, many people live much longer than 5 years (and many are cured). Also, people with small intestine cancer can die of other things. The numbers below, known as observed survival, don’t take that into account.

In order to get 5-year survival rates, doctors have to look at people who were treated at least 5 years ago. Improvements in treatment since then may result in a more favorable outlook for people being diagnosed with small intestine cancer now.

Survival rates are often based on previous outcomes of large numbers of people who had the disease, but they cannot predict what will happen in any particular person’s case. Many other factors may affect a person’s outlook, such as their age, general health, the grade of the cancer, and how well the cancer responds to treatment. Your doctor can tell you how the numbers below may apply to your particular situation.

The numbers below were published in 2010 in the 7th edition of the AJCC Staging Manual. They come from the National Cancer Data Base, and are based on people diagnosed with small intestine adenocarcinoma between 1998 and 2002.
