#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.
