Chromogranin A is a protein produced by cells found in endocrine glands throughout the body. Certain types of tumors caused increased production of Chromogranin A. Carcinoid tumors, which typically form in the lungs or gastrointestinal tract are often associated with increased CGA levels. 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 ...Patient Billing and Payment Information.
