#175 The Immunohistochemical (IHC) Expression and Prognostic Value of ER, PR, and HER2/neu in Pancreatic and Small Intestinal Neuroendocrine Tumors
Introduction: There has been limited study of ER and PR expression in gastrointestinal neuroendocrine tumors (GINETs) and data on HER2/neu overexpression in GINETS has been conflicting.

#1872 Whole-Exome Sequencing (WES) of Samples from Patients (pts) Classified as Exceptional Responders (ER) vs Poor Responders (PO) to Targeted Therapies in Pancreatic Neuroendocrine Tumours (pNETs).
Introduction: Sunitinib (SU) and everolimus (EVE) changed the treatment landscape for patients with well-differentiated pNETs. However, no predictive biomarkers have been established for these drug

#1544 Immunohistochemical Expression of Estrogen and Progesterone Receptors in Neuroendocrine Tumors
Introduction: Expression of progesterone (PR) and estrogen receptor (ER) in some neuroendocrine tumors (NET) raises the possibility of hormonal regulation in these tumors, but those prevalence and clinical implication are unknown.

#1592 Primary Neuroendocrine Carcinoma of the Breast: A Diagnostic Approach to the Special Type of Breast Malignancy
Introduction: WHO classification from 2003 defines primary neuroendocrine carcinomas (NEC) of the breast as a group of tumors with expression of neuroendocrine markers in more than 50% of tumor cells. In the current WHO classification this category is renamed to “carcinomas with neuroendocrine features” without defined clear-cut of the percentage of tumor cells positive for neuroendocrine markers.

#2712 HORMONET: Study of Tamoxifen in Well Differentiated Neuroendocrine Tumors (NET) and Hormone Receptor Positive Expression
Introduction: We have shown immunohistochemistry (IHC) expression of estrogen (ER) and progesterone receptors (PR) in 20.8% and 18.8% of 96 NET patients (pts). An old clinical trial (Mortel C, 1984) suggested antitumor effects of estrogen/progesterone-directed therapies in NET. Yet the effects of an antiestrogen agent in NET pts whose tumor express ER and/or PR are unknown.

#359 Expression of UCH-L1 in Pancreatic Endocrine Tumors and Its Clinical Significance
Introduction: Pancreatic endocrine tumors (PETs) are rare tumors with distinct clinical syndromes. There is a lack of reliable biomarker to distinguish benign and malignant form of PETs as well as to predict its prognosis. Our previous proteomic study on insulinoma found that overexpression of UCH-L1 in tumors. The diagnostic or prognostic value of this protein has not been well addressed in PETs.

#413 Expression of UCH-L1 in PETs and its Implications
Introduction: There is a lack of reliable biomarkers to distinguish benign from malignancy in pancreatic endocrine tumors (PETs) and to predict prognosis. Our previous study on insulinoma found the expression of UCH-L1 in these tumors. The diagnostic or prognostic value of this protein has not been well demonstrated in PETs.

#467 Thoracic and Gastroenteropancreatic (GEP) Neuroendocrine Tumors (NETs) and Ectopic Adrenocorticotropin (ACTH) Syndrome (EAS)
Introduction: Ectopic Adrenocorticotropin (ACTH) Syndrome (EAS) is associated with a variety of malignancies, mostly of neuroendocrine origin. Several series report on the relative contribution of EAS in the spectrum of Cushing’s syndrome. However, information on the incidence/prevalence of EAS in the setting of patients diagnosed with thoracic or gastroenteropancreatic (GEP) neuroendocrine tumors (NETs) is virtually absent.
