#4055 Incidental endoscopic removal of a rectal neuroendocrine tumor: What to do?

Introduction: An increasing incidence of rectal neuroendocrine tumors (rNETs) has been reported as a consequence of the progressive spread of screening colonoscopy. Guidelines suggest endoscopic resection, preferably by endoscopic mucosal resection (EMR) or submucosal dissection, for rNETs

#4031 68-Gallium DOTANOC PET/CT pitfall in adnexal tumor

Introduction: PET/CT with 68Ga-DOTA is a commonly used tool in the baseline evaluation and follow-up of NETs due to its high specificity and sensitivity, showing better performance than CT in detecting primary and metastatic disease. However, we must know more about its normal physiological distribution, its variation in pathologies, and the possibility of confusion with benign processes to optimize its interpretation.

#3988 Management and surveillance for rectal neuroendocrine tumors: A single-centre retrospective analysis and comparison with ENETS guidelines

Introduction: Rectal neuroendocrine tumors (rNETs) are rare but are increasing in incidence. Current management and surveillance recommendations are primarily based on low-grade evidence.

#3986 The application of 68Ga-DOTANOC PET/CT after endoscopic submucosal dissection for patients with rectal NET

Introduction: Some rectal neuroendocrine tumors (NETs) are accidentally detected by colonoscopy screening. Due to the lack of cognition of endoscopic feature of rectal NET, endoscopic tumor resection has always done without metastasis screening.

#3946 The value of 68Ga-DOTANOC and 18F-FDG PET/CT for predicting the prognosis of patients with metastatic rectal neuroendocrine tumor

Introduction: Rectal neuroendocrine tumor (RNET) is common second only to pancreatic neuroendocrine tumor in Chinese population. Some studies demonstrated that 18F-FDG PET/CT is useful for risk stratification of GEP-NET and is even better than histologic grade to predict the prognosis.
