Gastric neuroendocrine tumors (G-NETs) are rare tumors originating from the gastric mucosa, classified into three subtypes based on their characteristics and behavior. Type 1 and 2 are typically multifocal and associated with elevated serum gastrin levels. Type 2 causes symptoms like abdominal pain and diarrhea. Type 3, sporadic and solitary, has the most aggressive phenotype. Treatment and prognosis vary based on tumor type, size, and stage, with type 1 having the best prognosis and type 3 having the worst. A comprehensive review discusses the presentation, workup, and surgical management of G-NETs.
