Core Tip

Core Tip: Coexisting primary adenocarcinoma of the colon and neuroendocrine tumor of the duodenum (D-NET) is a rare occurrence in clinical practice. We report the details of a case involving a female patient with coexisting primary adenocarcinoma of the colon and D-NET diagnosed by imaging and surgical specimens. The tumors were treated by surgery and four courses of chemotherapy. The patient achieved a favorable clinical prognosis. The classification and treatment criteria for D-NETs combined with a second primary cancer have not yet been determined. Our experience may help others to diagnose and manage similar patients.
