#4236 Do metastatic appendiceal NETs ever develop metachronously after appendectomy or right hemicolectomy?

Introduction: Appendiceal NETs are typically detected incidentally during appendectomy. A recent study reported no cases of metachronous metastases among patients (pts) with primary tumors

#4234 Association of long-term PPI use with low-risk gastric neuroendocrine tumor

Introduction: Gastric neuroendocrine tumors are rare neoplasms, comprising approximately 2% of all gastric tumors, and develop from enterochromaffin-like (ECL) cells in the gastric mucosa. Type I and II develop due to hypergastrinemia and ECL cell hyperplasia; type III typically occurs sporadically, tend to be more aggressive, present metastatically in > 50% of cases, have normal fasting gastrin levels, and vary histopathologically from well- to poorly differentiated.
