A Comparison of Three Chromogranin A Assays in Patients with Neuroendocrine Tumors Abstract #783

Introduction: Chromogranin A (CgA) is the most important general tumor marker used in the diagnosis and follow-up of patients with neuroendocrine tumors (NET). CgA assays may have different sensitivities, which is of importance for the clinical diagnosis and handling of NET patients.
Aim(s): To compare the sensitivities of three different CgA assays in NET patients.
Materials and methods: We measured CgA in 42 NET patients (male/female: 23/19, median age: 63 years (range 29-85 years)). Twenty-five patients had liver metastases, eight had local disease, and nine were disease-free after surgery. We studied a RIA in-house assay (RH RIA assay) (Rigshospitalet, Copenhagen, Denmark); NEOLISATM (Euro Diagnostica, Malmö, Sweden) and EURIA CgA RIA (Euro Diagnostica, Malmö, Sweden).

#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.

#78 The diagnostic and prognostic value of elevated proGRP levels in well- and moderately differentiated neuroendocrine tumors
Introduction: Chromogranin A (CgA) is the most frequently used marker in well- (grade 1) and moderately (grade 2) differentiated NETs. Although CgA is a more sensitive marker than the 5-HIAA, which was widely used until the last decade, CgA has some limitations. False-positively elevated CgA may occur in renal impairment, atrophic gastritis and during treatment of proton-pump inhibitors. Progastrin-releasing peptide (proGRP) was recently reported as a promising tumor marker for small cell lung cancer. Limited data suggests that ProGRP may be a potential tumor marker in NE tumors.

#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.

#231 Chromogranin A as a Predictor of Progression, Regression or Stable Disease in Ileo-Cecal Neuroendocrine Tumors
Introduction: Chromogranin A is an excellent marker for NET and tumor volume. Plasma CgA is suggested as the most reliable marker in follow-up of patients with some types of NET.
