#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

#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.

#3765 Heterogeneity and potential therapeutic targets of rectal neuroendocrine tumors by single cell RNA-sequencing combined with spatial omics

Introduction: The incidence of rectal neuroendocrine tumors (rNETs) has increased rapidly in the past 30 years. However, the molecular mechanism of its occurrence and development is still unclear, and the basic research is relatively backward.
