Comparing CgA levels in benign insulinomas with the levels in patients with localized non-insulinomas. The serum levels of CgA in 56 patinets with localized insulinomas were similar to the levels in 12 patients with localized non-insulinomas, P = 0.693. It can be seen that 3 of 56 patients with localized insulinomas had the CgA levels more than 120.8 ng/ml (i.e. 2 fold more than cut-off values for insulinoma), whereas 4 of 12 patients with localized non-insulinomas had CgA levels more than 242 ng/ml (2 fold more than cut-off values for non-insulinoma).
