#4426 A case of giant neuroendocrine tumour of unknown primary site

Introduction: The liver is a common site for metastatic neuroendocrine tumours. NETs primary to the liver are rare, and it is difficult to determine whether a neuroendocrine tumour in the liver is primary or metastatic in patients in whom no tumour has been found elsewhere.

#4416 Medicine treatment of functional pancreatic neuroendocrine tumour with hypercalcaemia

Introduction: Functional pancreatic neuroendocrine tumours (F-PNETs) are capable of secreting parathyroid hormone-related protein (PTHrP), causing humoral hypercalcaemia of malignancy (HHM).

#4376 Analysis of clinical features and prognosis of 195 cases of gastrointestinal and pancreatic neuroendocrine tumours

Introduction: Neuroendocrine tumours are most common in the stomach and pancreas. With the Ki-67 positive index of NET G3 and NEC both above 20%, there is a view that NET G3 will not evolve into NEC.
