Core Tip

Core Tip: The predominant type of gastric remnant cancer is adenocarcinoma, whereas neuroendocrine carcinoma is particularly rare. Currently, there are few previous reports of gastric mixed neuroendocrine carcinomas (GMNECs). The information provided in this report will improve our understanding of the carcinogenesis, biology, and behavior of GMNEC and gastric remnant cancer.
