Current markers include plasma levels of chromogranin A, tumor metastases and Ki67 staining to determine the tumor proliferation rate. Previous studies have shown that FDG-PET for neuroendocrine ...

Biomarkers such as chromogranin A play an important role in the diagnosis and follow-up of patients with neuroendocrine tumors. Molecular imaging, including somatostatin receptor scintigraphy but ...

The tissue was strongly positive for synaptophysin and chromogranin, and neurofilament staining was focally positive (see figure 4). Epithelial membrane antigen (EMA), glial fibrillar acidic protein ...
