Chromogranin a labcorp.
Chromogranin A is a member of the granin glycoprotein family that is expressed by the endocrine and neuroendocrine cells of different organs. Intracellularly, chromogranin A contributes to the regulation of secretion and gives several cleavage products after secretion. Some of its cleavage products modify the hormone functions in autocrine and ...

One of the disadvantages is its low specificity and the existence of a number of processes leading to an increase in its concentration, which often results in confusion and diagnostic difficulties.
Interpretation. Follow-up/Surveillance: In patients diagnosed with gastroenteropancreatic neuroendocrine tumors (GEP-NET) grade 1 and grade 2, when used in combination with clinical symptoms and/or other laboratory parameters, the change of chromogranin A (CgA) concentration over time provides diagnostic information whether a tumor progression has occurred.

Chromogranin A (CgA) not only plays an important role in pathologic diagnosis, but is also used as a circulating biomarker in patients with gastroenteropancreatic neuroendocrine neoplasm (GEP-NEN). However, the relationship between immunohistochemistry (IHC) expression and serum levels of CgA has not been investigated.

The currently used general markers for NEN patients in clinical practice are chromogranin A (CgA) and 5-hydroxyindoleacetic acid (5HIAA). Although CgA is a sensitive marker for NENs and correlates well to tumor burden and survival, it is rather unspecific since it is co-secreted with peptide hormones from neuroendocrine cells of several organs ...
