How accurate is pancreatic polypeptide in detecting pancreas tumor?

It is not: In my opinion, it should only be used when a diagnosis has been made. It can be a good serum marker to follow. Hope this helps.

NOT VERY!!!: Hi. Pancreatic polypeptide (PP) is NOT a screening test for pancreatic tumors. The only pancreatic cells that make PP are rare neuroendocrine cells in the Islets of Langerhans (an already tiny fraction of the pancreas). And those would be a TINY, TINY fraction of all pancreatic tumors. But hey, if it's a PP secreting neuroendocrine tumor of the pancreas, you'd have it dialed! Good luck!
