#2926 O-Positive Blood Group Is Associated with Prolonged Recurrence-Free Survival Following Pancreatic Neuroendocrine Tumor (PanNET) Curative-Intent Surgical Resection

Introduction: The ABO blood group may influence the development and progression of cancer. In particular, the prognosis of pancreatic adenocarcinoma is better in patients with blood group O. This has not been extensively explored in PanNET.

#2909 Serotonin-Secreting NeuroEndocrine Neoplasms of the Pancreas: Which Are the Primary Pancreatic Carcinoids?

Introduction: Serotonin-secreting pancreatic neuroendocrine neoplasms (5-HT-secreting pNENs) are very rare. They are characterised by high urinary 5-hydroxyindole-acetic acid (5-HIAA) levels (or high serum 5-HT levels).
