In [[oncology]], '''small intestine cancer''', also '''small bowel cancer''' and '''cancer of the small bowel''', is a [[cancer]] of the [[small intestine]]. It is relatively rare compared to other gastrointestinal malignancies such as [[gastric cancer]] (stomach cancer) and [[colorectal cancer]].<ref name=terry>Terry SM, Santora T.

==[[Small intestine cancer overview|Overview]]==


Small intestine cancer can be subdivided into duodenal cancer (the first part of the small intestine) and cancer of the [[jejunum]] and [[ileum]] (the later two parts of the small intestine). 
==[[Small intestine cancer historical perspective|Historical Perspective]]==


Several different subtypes of small intestine cancer exist.  These include:
==[[Small intestine cancer classification|Classification]]==
*[[Adenocarcinoma]]
*[[Gastrointestinal stromal tumor]]
*[[Lymphoma]]
*[[Carcinoid]] ([[ileum]])


==Duodenal cancer==
==[[Small intestine cancer pathophysiology|Pathophysiology]]==

Duodenal cancer is a [[cancer]] in the beginning section of the [[small intestine]]. It is relatively rare compared to [[gastric cancer]] and [[colorectal cancer]]. Its histology is usually [[adenocarcinoma]].  Familial adenomatous polyposis (FAP) is a risk factor for developing this cancer. 


The [[duodenum]] is the first part of the small intestine. It is located between the [[stomach]] and the [[jejunum]]. After foods combine with stomach acid, they descend into the duodenum where they mix with bile from the [[gall bladder]] and digestive juices from the [[pancreas]].
==[[Small intestine cancer causes|Causes]]==


Duodenal cancer is difficult to remove surgically because of the area that it resides in, there are many blood vessels supplying the lower body.  Chemotherapy is sometimes used to try and shrink the canceous mass.  Other times intestinal bypass surgery is tried to reroute the stomache to intestine connection around the blockage.
==[[Small intestine cancer differential diagnosis|Differentiating Small Intestine Cancer from other Diseases]]==
A 'Whipple' is a possible surgery that is tried sometimes with this cancer.


The cancerous mass tends to block food from getting to the small intestine. If food can not get to the intestines, it will cause pain, acid reflux, and weight loss because the food can not get to where it is supposed to be processed and absorbed by the body.
==[[Small intestine cancer epidemiology and demographics|Epidemiology and Demographics]]==


Some patients are fitted with tubes to either add nutrients (feeding tubes)  or drainage tubes to remove excess processed food that can not pass the blockage.
==[[Small intestine cancer risk factors|Risk Factors]]==


Patients with duodenal cancer may experience abdominal pain, weight loss, nausea, vomiting, and chronic GI bleeding.
