Chromogranin A: From Laboratory to Clinical Aspects of Patients with Neuroendocrine Tumors

Figure 1

Distribution of Cg A in patients with NET and chronic atrophic gastritis (CAG). In the NET group, higher Cg A levels are observed in patients with diffuse disease (DD) compared with patients with local (LD) or hepatic (HD) disease. In the disease-free patients (DF), Cg A levels were the lowest of all. In the CAG group, higher Cg A levels are observed in patients with hyperplasia (H) of ECL cells, compared with patients without hyperplasia [66].
