Core Tip

Core Tip: Gastric neuroendocrine tumors are classified into three types, with type I and type II having a better prognosis, while type III presents a more aggressive course. Early diagnosis and treatment, including endoscopic resection and emerging therapies like Peptide Receptor Radionuclide Therapy, are key to improving outcomes, particularly for advanced cases. Further research is needed to enhance diagnostic accuracy and treatment options.
