Small bowel adenocarcinoma is a relatively rare malignancy. Only limited information is available on the incidence, prognosis, and role of chemotherapy in the treatment of this disease. We present a review of currently available clinical data to assist the practicing oncologist in the treatment of these patients. Approximately 5,300 new cases and 1,100 deaths from small bowel adenocarcinoma are reported annually in the United States. Increased incidence is seen in patients with Crohn's disease, hereditary nonpolyposis colorectal cancer, and familial adenomatouspolyposis. Factors associated with poor prognosis are age > 75 years, lack of surgical resection, advanced stage, and tumor arising in the duodenum. The median survival of patients with localized, locally advanced, and metastatic disease is 50.1, 22.2, and 8.6 months, respectively. Few data exist on the use of (neo)adjuvant or palliative chemo(radio)therapy in this setting. Fluorouracil (5-FU)based chemotherapy, as a single agent or in combination with others, has been used in most case series. Duodenal adenocarcinoma accounts for more than 50% of all cases of small bowel adenocarcinoma. Resectability is the key prognostic factor, along with age, performance status, tumor location, and presence of distant metastasis. Although the activity of 5-FU-based regimens has been documented, the assessment of clinical benefit is hindered by the lack of prospective, randomized data.
