Types of Small Intestine Cancer:
Adenocarcinoma derives from the gland cells that form intestinal epithelium. It is the most frequently found type of small intestine cancer. Usually adenocarcinomas occur in the area near the stomach.
Leiomyosarcoma is the most often found disease of the small intestine among primary sarcomas. It is started in the smooth muscle cells of the small bowel. Often these tumors occur near the colon.
Carcinoid tumors is a slow-growing type of cancer. These neuroendocrine tumors may secrete substances such as serotonin or prostaglandins, causing «carcinoid syndrome».
Lymphoma is a cancer of the lymph system ( non-Hodgkin lymphoma type). Usually occurs in the jejunum or ileum.
Gastrointestinal stromal tumor (GIST) can grow from the interstitial cells of Cajal (ICC). These cells are located in the wall of the digestive system and help to move food through it.
First 4 types make up the majority of small intestine malignancies.
Small Bowel Cancer: Diagnosis
Doctors use specific tests to diagnose small intestine cancer. Not all tests are used for every person. When choosing a test doctor consuders symptoms, type of suspected cancer, patient`s age and results of earlier medical tests. Diagnostics of small intestine cancer includes various blood tests, biopsy, CT scan, PET scan, MRI and endoscopy.
Small Intestine Surgery Treatment Options
The main ways to treat small intestine cancer are small intestine surgery, chemotherapy and radiotherapy.
Surgery is the basic treatment option. During laparoscopic («keyhole») procedure a tumor is removed along with some area of normal tissue surrounding it. To decrease the risk of spreading the cancer surgery has to be done by an experienced surgeon. Bookimed offers only best equipped clinics with world's top-abdominal surgeons. The cost of small intestine surgery depends on type, location and size of tumor.
Small Intestine Cancer Survival Rate
Survival rate for all types of small bowel cancer is 67%.
The overall 5-year survival rate for small intestine cancer that can be removed:
- adenocarcinoma 20%;
- leiomyosarcoma 50%;
- malignant GIST 76%.
