#2215 Development of Multiplex Biomarker Assay to Subtype Pancreatic Neuroendocrine Tumors (PanNETs) with Distinct Prognosis and Mutations
Introduction: Overall 5-year survival for PanNETs ranges from 25-100%. The treatment paradigm for PanNETs largely based upon grades, which is significantly heterogeneous. We previously defined three molecular subtypes (distributed grades) of PanNETs using PanNETassigner signature. There is an unmet clinical need for prognostic and predictive biomarkers and clinically-relevant assays to complement grade and improve patient stratification.

#20 Paraneoplastic antigen Ma2 (PNMA2) auto-antibodies as biomarkers for early small intestine neuroendocrine tumors detection
Introduction: Small intestine neuroendocrine tumors (NETs) comprise well-differentiated NET (benign carcinoid), well-differentiated neuroendocrine carcinoma (malignant carcinoid) and poorly differentiated neuroendocrine carcinoma (NEC). The majority of NET patients have developed liver metastases at the time of diagnosis and surgery is then seldom curative. Novel predictive, diagnostic and prognostic markers are thus needed to improve our capabilities to diagnose and cure these tumors. We have previously identified six novel marker genes for neuroendocrine tumor cells by using Affymetrix microarrays and advanced bioinformatics. One of this markers, the paraneoplastic antigen Ma2 (PNMA2), which is normally expressed only in nervous tissue, can in the process of carcinogenesis be detected in tumors located outside the nervous system. The finding that Ma2 is expressed in small intestine neuroendocrine primary tumors and their metastases made it interesting to screen whether antibodies against Ma2 are present in the serum of NET patients.

#152 Validation of a new assay that uses 2 monoclonal antibodies to measure intact and fragmented plasma CgA levels
Introduction: Plasma chromogranin A (CgA) levels are elevated in a variety of neuroendocrine tumors (NETs) and are used to aid in diagnosis, prognosis, and monitoring of treatment effects in NETs patients. We evaluated a newer sandwich ELISA assay (Cisbio US, Bedford, MA, USA) that utilizes two monoclonal antibodies that bind to the mid-region of the CgA protein and allow measurement of intact and fragmented circulating CgA. The results from the assay validation indicative of its overall robustness in terms of sensitivity, specificity, reproducibility, and stability are presented here.

#193 Paraneoplastic Antigen Ma2 Autoantibodies as Specific Blood Biomarkers for Detection of Early Recurrence of Small Intestine Neuroendocrine Tumors
Introduction: Small intestine neuroendocrine tumors (SI-NETs) are rare fatal cancers. Many patients develop metastatis before diagnosis. There is no available curative treatment for patients with metastasis.

#623 Measurement of Serum Chromogranin A Level in 56 Patients with Neuroendocrine Tumors Using Immunoradiometric Assay
Introduction: More NETs have been diagnosed with the increasing awareness of the diseases, but few centers in China have introduced CgA testing as a tumor marker.

#595 A Single Fasting Plasma 5-HIAA Value Correlates with 24-Hour Urinary 5-HIAA Values and Other Biomarkers in Midgut Neuroendocrine Tumors (NETs)
Introduction: 5-hydoxyindoleacetic acid (5-HIAA) is used for the evaluation of neuroendocrine tumors (NETs), however, the current 5-HIAA assay requires a 24-hour urine collection which is inconvenient.

#1177 An Isolated Abnormal Chromogranin B Is Associated with Pancreato-Duodenal NETs and the Presence of Liver Metastases
Introduction: Chromogranin B (CgB) is a soluble secretory protein like chromogranin A (CgA) that has been reported to be elevated in patients with neuroendocrine tumours (NETs) but is not routinely assessed.

#2202 Assessment of the Clinical Utility of the NETest in a US Registry-Based Study
Introduction: The clinical relevance of molecular biomarkers in oncology management has been recognized in breast and lung cancer. Current biomarkers in NET disease have limited clinical utility.
