Clinical Correlates of Discrepant Results of Chromogranin a versus Serotonin Markers in Patients with Neuroendocrine Tumors Abstract #1917

Introduction: Neuroendocrine tumors lead to elevated chromogranin A levels and elevated serotonin markers (urinary 5HIAA and platelet serotonin). These markers are employed for diagnosis and monitoring.
Aim(s): To determine the clinical correlates of chromogranin A levels discrepant to serotonin markers.
Materials and methods: Chromogranin A, urine 5HIAA and platelet serotonin were evaluated in 143 patients with neuroendocrine tumors (grade 1 and 2) and neuroendocrine cancers (grade 3) from 2005 to 2015.

#12 Chromogranin A as a predictor of progression, regression or stable disease in ileo-cecal (midgut) carcinoid tumors
Introduction: A general characteristic for NETs is their expression of certain proteins, such as chromogranin A (CgA), which is released from the dense core vesicles of NE cells, occasionally together with cell specific hormones, such as gastrin and serotonin. Plasma CgA seems to be closely related to tumor burden of intestinal carcinoid tumors in humans.

#34 Plasma Chromogranin A(CgA) and Urinary 5 Hydroxy-indoleacetic acid(5-HIAA) use in monitoring somatostatin analogue(SSA) therapy at Newcastle NHS Foundation Trust
Introduction: Two main biochemical markers, plasma chromogranin A (CgA) and urinary 5 hydroxy-indoleacetic acid (5-HIAA) are used to aid staging and monitoring of patients with neuroendocrine (NET) tumors. Somatostatin analogues (SSA) such as octreotide and lanreotide have been used to alleviate symptoms and disease progression in NET patients. This study evaluates the use of CgA and 5HIAA in monitoring NET patients on SSA therapy at Newcastle NHS Foundation Trust.

#88 EpCam expression and detection of circulating tumor cells in neuroendocrine tumors
Introduction: Using the CellSearchTM system, circulating tumor cells (CTCs) can be reproducibly enumerated according to expression of EpCAM and cytokeratins 8, 18 or 19 and the absence of the haemopoietic marker CD45. The number of CTCs detected in 7.5 mls blood has been shown to correlate with prognosis in breast, colon and prostate cancer and can predict response to therapy. Neuroendocrine tumors (NETs) have not previously been reported to express EpCAM and have not been systematically assessed for presence of CTCs. We have therefore explored the expression of EpCAM in NETs and the detection of NET cells in the circulation.
