Abstract Duodenal adenocarcinoma is an uncommon, malignant tumor usually accompanied by a poor prognosis. We identified 3150 duodenal adenocarcinoma cases from the SEER database (1988–2013) to analyze clinical characteristics and outcomes. The Kaplan–Meier method was used to evaluate cancer-specific survival (CSS). Cox regression analysis was used to explore the prognostic factors of CSS. Adverse prognostic factors include higher tumor grade, later stage, tumor size ≥ 2cm, positive regional lymph nodes, and not undergoing surgical resection. Our results suggest, surgery is the optimal treatment for duodenal cancer, and combined radiotherapy does not improve survival.
