Prognosis

• Fewer than 35% of people who have adenocarcinoma of the small bowel live past 5 years.



• The survival chances are better if the cancer is limited to the inner walls of the small intestine and the lymph nodes are not involved.



• The chance of recovery is better still in people who have a carcinoid tumor and lymphoma of the small bowel. These malignancies tend to respond better to chemotherapy and radiation treatment when doctors cannot completely remove the tumor.



• The prognosis is poor, however, if a person has a small bowel lymphoma underlying celiac disease or if the person's immune system is weakened.
