Small cell lung cancer (SCLC) is considered a neuroendocrine tumour. It is possible to demonstrate CgA expression in SCLC by immunohistochemical methods. Since CgA is released to the circulation it might also work as a clinical tumour marker.We report the case of a 50-year-old female patient who presented with symptoms suggestive of a serotonin- secreting neuroendocrine neoplasm. In addition, her serum chromogranin A (CA) level was elevated by more than 8-fold.Chromogranin A Testing. Test code (s) 31912, 31911. Question 1.

Background: Chromogranin A (CgA), neuron specific enolase (NSE), carcinoembryonic antigen (CEA), and urinary 5-hydroxyindole-3-acetic acid (5-HIAA) are the markers currently used in the diagnosis, prognosis, and follow-up of patients with neuroendocrine tumors (NETs). The authors examined the role of such biomarkers in a large series of patients with NETs.

The most important marker, chromogranin A (CgA), is a constitutive secretory product of most neuroendocrine tumors. Depending on the extent of the disease, plasma CgA is elevated in > 60% of patients. CgA levels may correlate with tumor volumes, but care should be taken in measuring CgA and interpreting the results.Chromogranin A is also elevated in 80% to 90% of patients with symptomatic foregut and midgut tumors. -Urine serotonin is in most circumstances the least likely marker to be elevated. The exception is tumors (usually foregut tumors) that produce predominately 5-HTP, rather than serotonin, and also secrete little, if any, chromogranin A.General Information. Chromogranin A (CgA) is a protein found in and released from neuroendocrine cells. Neuroendocrine cells, and the endocrine system glands that they are found in, can give rise to a variety of tumours, both benign and malignant.
