#3132 Plasmatic and urinary 5-hydroxyindolacetic acid measurements in patients with midgut neuroendocrine tumors: A GTE study

Introduction: Although 24-hour urinary 5-hydroxyindolacetic acid (24u5HIAA) is a key biomarker in midgut NET, it may be inaccurate and inconvenient.

#2889 Transcatheter Arterial Embolization (TAE) of NEN Metastases: Efficacy and Predictors of Response

Introduction: Transcatheter-Arterial embolization (TAE) is an established regional, palliative treatment option for liver metastases in patients (pts) with neuroendocrine neoplasms (NENs).

#2213 Imaging Modality Depending on the Levels of Tumor Markers

Introduction: 18 F-Fluorodihydroxyphenylalanine(18F)-FDOPA positron emission tomography (PET)/computed tomography (CT) has the advantage of being a noninvasive test and is by far the most promising imaging modality for neuroendocrine tumors (NETs).

#640 Chomogranin A, NSE, and 5-Hydroxyindolacetic Acid Measurements in Malignant Carcinoids

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.
