Recent systematic reviews could not prove a prognostic value of current existing biochemical markers such as chromogranin A, the NETest (a transcriptomic‐based biomarker test for detecting neuroendocrine tumors) and pancreatic polypeptide (PP) in MEN1‐associated pNET.6, 19, 20, 21, 22. The gene discussed is PPY; the disease is neuroendocrine neoplasm.
