#4618 The exceptionally rare phenomenon of well-differentiated colon neuroendocrine tumours

Introduction: Colonic neuroendocrine tumours (NETs), excluding rectal NETs, are often described as relatively common and aggressive, with inferior median survival compared to other gastrointestinal (GI) primary sites. However, epidemiological databases may conflate well-differentiated NETs with poorly differentiated NECs, leading to unclear data on prevalence, clinical behaviour, and prognosis of well-differentiated colonic NETs.

#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.

#3355 Clinicopathologic impact of peptide hormonal expression in rectal neuroendocrine tumor

Introduction: Although numerous types of neuroendocrine cells constitute GEP-NETs, the clinical behaviours and prognostic implications of multiple peptide hormonal expression have not been comprehensively evaluated in rectal NETs.
