Chapter 76 Cancer of the Small Bowel Laura Doyon, Alexander Greenstein and Adrian Greenstein Summary of Key Points Incidence • Small bowel tumors are rare, with incidence of less than 10% of new gastrointestinal cancer diagnoses and less than 1% of all new diagnosed cancers each year. • Genes involved include APC and KIT and mismatch-repair genes. Biological Characteristics • Malignant small bowel tumors consist of carcinoid (37.4%), adenocarcinoma (36.9%), lymphomas (17.3%), and gastrointestinal stromal tumors (GISTs) (8.4%). Staging Evaluation • Staging is based on the American Joint Committee on Cancer (AJCC) tumor-node-metastasis (TNM) staging system. Gastrointestinal (GI) lymphoma is staged with the Ann Arbor system based on lymphatic and extra lymphatic involvement above and below the diaphragm. Primary Therapy/Results • Primary therapy for small bowel neoplasms is surgical resection. Appropriate lymphadenectomy must be performed for adenocarcinoma and carcinoid tumors. Adjuvant Therapy Only gold members can continue reading.
