Neuroendocrine Tumor Markers

open access: yesFrontiers in Neuroendocrinology, 2001
Tumor markers used in the diagnosis and follow-up of patients with neuroendocrine tumors are in most instances not specific for a given tumor and circulate under normal conditions in the serum, making their use as an early diagnostic tool difficult (low sensitivity).
