According to information collected from 1998 to 2002 by the National Cancer Data Base, the prognosis for small intestine cancer affecting the duodenum, jejunum and ileum is a five-year survival rate of 55 percent in stage I and 5 percent in stage IV, explains the American Cancer Society. The duodenum is the first segment located between the stomach and large intestine, says the National Cancer Institute.Continue Reading
As a part of the digestive system, the small intestine is responsible for helping remove nutrients from food before waste material is moved out of the body. Small intestine cancer is a rare form of cancer that has an increased risk with a poor diet and a health history of Crohn's disease, celiac disease or familiar adenomatous polyposis, states the National Cancer Institute. Other factors affecting the prognosis of the patient include age, how the cancer responds to treatment, overall health and the stage of cancer, reports the American Cancer Society.
There are five different types of small intestine cancer, and the most common is adenocarcinoma, which affects the lining of the small intestine. If the glandular cells making up the lining expand, the intestine is blocked, according to the National Cancer Institute. In stage I, the survival rate is significantly higher than if the prognosis is given in later stages. For example, the survival rate drops from 55 percent in stage I to 49 percent in stage IIA, notes the American Cancer Society.Learn more about Cancer
