The median values of CgA levels in 86 healthy controls, 57 patients with insulinomas and 32 patients with non-insulinoma PNETs were 53.4 ng/ml (range 39.1 – 94.1 ng/ml), 64.8 ng/ml (range 25.0 – 164.2 ng/ml) and 192.5 ng/ml (range 26.9 – 9020.7 ng/ml), respectively (Figure 1). The gene discussed is CGA; the disease is pancreatic insulinoma.
