A high chromogranin A: Is it always a tumor?
نویسندگان
چکیده
Human chromogranin A (CgA) is a secretory protein that is used as a tissue marker for neuroendocrine tumors (NETs) (1,2). In patients with carcinoids and pheochromocytomas, CgA is a more stable marker than plasma levels of serotonin, catecholamines and their urinary metabolites (3). It may also be elevated due to several other causes; however, the use of proton pump inhibitors (PPIs) is the most important reason if elevated CgA level is not caused by a NET (4).
