Background: Gastric neuroendocrine tumours (g-NETs) constitute about 7% of digestive NETs, with type 1 g-NETs, linked to chronic atrophic gastritis, accounting for 80% of cases. These tumours are generally small, low-grade, and exhibit excellent long-term survival rates. Increased endoscopy and awareness have raised their incidence, prompting interest in management strategies. Current guidelines recommend either endoscopic surveillance or resection for type 1 g-NETs <10 mm...

Background: Rectal neuroendocrine tumours (r-NETs) are the second most common neuroendocrine tumours in the digestive tract, with increasing incidence due to improved colonoscopy and cancer screening. These small, yellowish, low-grade lesions are often found incidentally during colonoscopies and generally have a favourable prognosis, with median survival sometimes exceeding 30 years. However, up to 20% of r-NETs may be misdiagnosed during endoscopy, risking inadequate treatmen...
