#4435 Clinicopathological characteristics and prognosis of 12191 patients with pancreatic neuroendocrine neoplasms

Introduction: Pancreatic neuroendocrine neoplasms (P-NENs) are a group of tumours originating from pancreatic neuroendocrine cells. Although these tumours are relatively rare, studies on them have gradually increased in recent years.

#4414 Impact of chromogranin A expression on clinicopathological characteristics and prognosis in patients with gastrointestinal tumours exhibiting neuroendocrine differentiation

Introduction: Pathological diagnosis of neuroendocrine differentiation (NED) relies on histomorphological assessment and specific markers, including chromogranin A (CgA) and synaptophysin (Syn). Previous studies indicate that tumours with a high proportion of CgA (+) exhibit increased malignancy and aggressiveness in neuroendocrine tumours, suggesting that CgA may serve as a prognostic marker.

#4348 Real-world clinicopathological features and outcome of elderly patients with thymic neuroendocrine neoplasms: A retrospective single-institution analysis

Introduction: Thymic neuroendocrine neoplasms (TNENs）are rare and heterogeneous diseases. With the aging of society, there has been an increase in the proportion of elderly patients with TNENs，however, research on these patients is limited.
