Introduction: GEP-NETs are a heterogeneous group of cancers more common in the small intestine which are usually asymptomatic. In patients with malignant carcinoids, a number of tumor markers (TMs) have been considered enclosing urinary 5-hydroxyindolacetic acid (5-HIAA), chromogranin A (CgA), and neuron-specific enolase (NSE) serum levels measurements. Unfortunately, the sensitivity of each TM largely depends on disease extent and the presence of functioning tumors, and thus their usefulness is still unclear.
