Background: Primary adenocarcinoma of the small bowel is a rare malignancy and is associated with poor survival outcome. Patient, tumor and treatment-related factors were analyzed for their association with recurrence and survival. Methods: Between 1971 and 2005, 64 patients with primary adenocarcinoma of the small bowel were treated at our institution. Clinico-pathologic data, operative details, postoperative treatment, recurrence pattern and survival were reviewed. Results: The most common clinical features at presentation included abdominal pain (n = 33; 51.6%) or bowel obstruction (n = 20; 31.3%). The most frequently involved portion of the small bowel was the duodenum (n = 41; 64%). A segmental bowel resection was performed in 30 patients and pancreaticoduodenectomy in 14 patients. Postoperative mortality and morbidity rates were 3.6% (n = 2) and 14.5% (n = 8), respectively. Of the 55 patients who underwent operative intervention, a curative resection was performed in 30 (54.5%). The most common sites of recurrence following a curative resection were the liver and lung. Median survival for all 64 patients was 18 months with a 5-year survival of 21.1%. On multivariate analysis, absence of distant metastatic disease (5-year survival 30.4%), curative resection (5-year survival 44.8%) and pathological T stage 1-3 (5-year survival 39.2%) were identified as independent predictors of survival. Conclusions: A curative resection in the absence of both distant metastases and pathological T4 tumor provides the best survival outcome. Recurrence at distant sites is the predominant pattern of failure following a curative resection, suggesting a role for adjuvant therapy.
