#4473 Somatostatin analogue delayed the recrudescence of stomach NET: A real-world study

Introduction: Type 1 gastric NENs (g-NENs) are common and relapse easily. Somstostatin analogues (SSAs) can inhibit gastrin secretion and cell proliferation. While the usage of SSAs in g-NENs is still controversial.

#4067 Malignancy of gastric neuroendocrine tumors is higher than pancreatic neuroendocrine tumors in Chinese population – Characterisation and analysis of factors

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%).

#4026 Neuroendocrine tumors in the stomach: An epidemiological analysis of Belgian Cancer Registry data

Introduction: GEP-NEN are rare and heterogeneous tumors including NET, NEC and MiNEN. NET are classified based on mitotic activity and Ki-67 index (G1, 2 and 3), NEC are always high grade (G3). Gastric NEN should be clinically subtyped as this has therapeutic implications (type 1, 2 and 3).
