#1582 Utility of Serum Chromogranin B Compared with Chromogranin A as a Biomarker in Japanese Patients with Pancreatic Neuroendocrine Tumors

Introduction: Currently, serum chromogranin A (CgA) is used as a biomarker for pancreatic neuroendocrine tumors (pNET); however, oral use of a proton pump inhibitor (PPI) and renal impairment can affect CgA.

#601 Chromogranin A is a Sensitive Marker of Progression or Regression

Introduction: One of the most common is gastroenteropancreatic (GEP) NET of the pancreas, which constitute about 30% of all GEP NET. CgA is an excellent marker for NET and tumor volume and plasma CgA is suggested as the most reliable marker in follow-up of GEP but only few studies have been published.

#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.

#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.
