Chromogranin A (CgA), a glycoprotein contained in secretion granules of neuroendocrine cells, is the most abundant granin in GEP-NETs and widely used as a circulating tumor marker, but only few studies have been published on the role of CgA in patients with GEP-PET, and the range of sensitivity were variously reported [8-10].Carcinoid tumors in the lungs. Signs and symptoms of carcinoid lung tumors include: Chest pain. Wheezing. Shortness of breath. Diarrhea.

Background Neuroendocrine tumors (NETs) are a form of cancer that differ from other neoplasia in that they synthesize, store, and secrete peptides, e.g., chromogranin A (CgA) and amines. A critical issue is late diagnosis due to failure to identify symptoms or to establish the biochemical diagnosis. We review here the utility of CgA measurement in NETs and describe its biological role and the ...
