Comprehensive Clinicopathologic, Immunohistochemical, and Genomic Profiling of Sporadic Ampullary Somatostatin-producing D-cell Neuroendocrine Tumors Identifies Recurrent HRAS Hotspot Mutations

Abstract Ampullary somatostatin-producing D-cell neuroendocrine tumors are rare neoplasms that may be associated with type 1 neurofibromatosis. The molecular features of sporadic ampullary somatostatin-producing D-cell neuroendocrine tumors (SAMSOM-NETs) remain poorly characteriz...

Association Between Proton Pump Inhibitor Use and Gastric Neuroendocrine Neoplasms in Autoimmune Gastritis: A Real‐World Propensity Score‐Matched Study From the Autoimmune gastRitis Italian netwOrk Study grOup

ABSTRACT Background and Aims Autoimmune gastritis (AIG) is characterized by chronic hypergastrinemia and is associated with an increased risk of gastric neuroendocrine neoplasms (gNENs). Because proton pump inhibitors (PPIs) further increase gastrin secretion, concerns have been...
