Overview
Small intestine cancer may be classified into adenocarcinoma, gastrointestinal stromal tumor, lymphoma, ileal carcinoid tumor, and sarcoma (most commonly leiomyosarcoma and rarely angiosarcoma or liposarcoma)
Classification
Small intestine cancer can be subdivided anatomically into:
- Duodenal cancer (the first part of the small intestine)
- Cancer of the jejunum and ileum (the later two parts of the small intestine)
Intestinal cancers can be classified into:[1]
- Benign tumors
- Malignant tumors
- Extra-intestinal tumors.
| Tumors | Types |
|---|---|
| Benign Tumors | 1- Leiomyoma
2-Lipoma 3-Hamartoma 4-Desmoid tumors |
| Malignant Tumors | 1-Adenocarcinoma
2-Leiomyosarcoma 3-Carcinoid tumors 4-Neuroendocrine tumors 5-Lymphomas |
| Extra- Intestinal Tumors | Metastasis to small intestine is mostly through:
1-Contagious spread (uncommon, mostly route of spread for Melanoma) 2-Peritoneal spread |
