Pancreatic neuroendocrine tumors: non-functional
What radiographic tests should be done for non-functioning neuroendocrine tumors of the pancreas?
Most of these patients present with symptoms related to the size of the tumor. One series reported 86% of patients presenting with abdominal pain, weight loss, or jaundice. Abdominal pain is the most common symptom present in 56% of these patients. Since most of these tumors do not become apparent until they are large enough to cause symptoms, CT scanning or MRI is usually the diagnostic procedure of choice. Serum measurement of chromogranin A and pancreatic polypeptide at the time of diagnosis may be helpful in monitoring patients for recurrence after resection.
