A Case of Concurrent Esophageal and Doudenal Double Primary Cancer / 대한소화기내시경학회지

The occurrence of double primary cancer of the esopbagus and duodenum is considered very rare. Moreover, it is difficult to manage this type of double cancer because esophageal cancer has a biologic tendency to early metastasis. We report a case of double primary cancer, which we have synchronously confirmed esophageal squamous cell carcinoma and duodenal adenocarcinoma with gastrofiberscopic biopsy, and then treated them by gastrojejunostomy and systemic chemotherapy.
