Malignancy of gastric neuroendocrine tumors is higher than pancreatic neuroendocrine tumors in Chinese population – Characterisation and analysis of factors

#4067

Introduction: Based on a large-scale epidemiological survey with a total of 2010 cases of neuroendocrine tumors (NENs) in the Chinese population from multiple centers, we observed that the malignancy of gastric NENs (G3, accounting for 67.2%) is higher than that of pancreatic NENs(G3, accounting for 9.9%).

Aim(s): We tried to find the reasons accounting for higher malignancy in gastric NENs than pancreatic.

Materials and methods: We compare the differences between gastric NENs and pancreatic NENs in demographic features, clinical manifestations, pathological characteristics, clinical grading, and staging. Logistic regression models were used to assess the association between these features and clinical staging, with statistical significance set at P<0.05.
