Basic testing for pancreatic neuroendocrine tumors (PNETs) – chromogranin A, synaptophysin, cytokeratin, Ki-67 (Mib-1), neuron specific enolase polyclonal, pan cytokeratin (AE1,3), protein gene product 9.5
Glucagonomas are pancreatic neuroendocrine tumors (PNETs) that produce excessive amounts of glucagon and are associated with a distinctive clinical syndrome. These tumors have a very high malignant potential, and are the third most common functional neuroendocrine tumor.
