Comparison of two chromogranin A assays and investigation of nonlinear specimens
Background: As a marker for functional and non-functional neuroendocrine tumors, serum chromogranin A (CgA) concentrations have shown value for detecting and monitoring disease. Here we describe a comparison between an established micro-titer plate assay

Paraneoplastic Cushing Syndrome in Gastrointestinal Neuroendocrine Tumour
Ectopic production of adrenocorticotropic hormone (ACTH) by gastrointestinal neuroendocrine tumours (NETs) is relatively uncommon. We report a rare case of a liver metastatic G1 low-grade NET of the intestine that induced hypercortisolism after surgical ...
