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.Labcorp test details for Chromogranin A. Elevated CGA levels may be seen in non-NEN malignancies including hepatocellular carcinoma 41 and breast cancer. 42.

Chromogranin-A (CgA) or parathyroid secretory protein 1 is encoded in the human by the gene CHGA. Cga is a member of the granin family of neuroendocrine secretory proteins. As such, it is located in secretory vesicles of neurons and endocrine cells such as islet beta cell secretory granules in the pancreas.

Numerous immunoassays have been developed to measure the levels of chromogranin A (CgA), a useful biomarker for diagnosing and monitoring generally heterogeneous neuroendocrine tumors (NETs). Here, we evaluated the imprecision and linearity of three such assays: KRYPTOR (ThermoFisher Scientific), NEOLISA …Chromogranin A is a secretory protein, composed of 439 amino acids, found in the large dense-core vesicles of the neuroendocrine cells. It belongs to the family of granins that includes chromogranin B, chromogranin C, and secretogranin II. Chromogranin A can be either measured in the serum or detected by immunohistochemistry in a tissue specimen.Chromogranin A is a widely used biomarker for the assessment of neuroendocrine neoplasms, especially for the diagnosis and management of those of gastroenteropancreatic origin. Generally, the sensitivity of this nonspecific marker test varies in different neoplasms, ranging from 10% to 100% and its specificity is from 68% to 100% [ 11 ].Well-differentiated neuroendocrine tumours (NETs) are rare, slow-growing tumours. Chromogranin A (CgA) has replaced the 24-h urine collection of 5-hydroxyindoleacetic acid and has become the most important tumour marker in the monitoring of NET during and after treatment and is recommended by the European NeuroEndocrine Tumor Society (Korse et al, 2009; O'Toole et al, 2009).Chromogranin A is recommended for the detection of specific antigens of interest in normal and neoplastic tissues, as an adjunct to conventional histopathology using non-immunologic histochemical stains. $ 1,123.36.
