#4555 Assessment of gastric mucosa conditions changes in patients with gastric neuroendocrine neoplasia type 1 during gastroprotective therapy

Introduction: Currently, the incidence of gastric neuroendocrine neoplasia (gNEN) has increased significantly. Most gNEN are developed on the background of chronic atrophic gastritis (about 90%). Despite this, the role of chronic atrophic gastritis treatment (gastroprotective therapy) in dynamic of gNEN remains unexplored.

#4497 Complex management of a long-term gastrinoma survivor with multimodal treatment approaches

Introduction: The prognosis of pancreatic gastrinomas is influenced by tumour burden, extent of metastasis, and treatment response, with 5-year survival rates ranging from 20% to 40%. Treatment for well-differentiated tumours typically include locoregional therapies, long-acting somatostatin analogues, molecular targeted agents, radionuclides, and chemotherapy.

#4366 Care of neuroendocrine tumours: The Collaborative of sUrgical Teams for NeuroEndocrine Tumors (CUTNETs)

Introduction: Despite the importance of surgical management, most data on NETs surgical care come from single-centre studies, limiting generalisability. To address these challenges and improve NETs surgical care, a worldwide Collaborative of Surgical Teams for NeuroEndocrine Tumors (CUTNETs) was created.
