#2118 Reassessment of Risk Factors Associated with Locoregional Lymph Nodal Metastases in Well-Differentiated Appendiceal Neuroendocrine Neoplasms
Introduction: To prevent loco-regional recurrence and subsequent development of distant metastases in Appendiceal Neuro-Endocrine Neoplasms (ANEN), the existing Guidelines have identified risk factors which would indicate a prophylactic right hemicolectomy(RHC).

#782 Appendix Well-Differentiated Neuroendocrine Tumors (A-WDNETs) at a Large Tertiary Center: Clinical-Pathological Features and Long-Term Follow-Up Evaluation
Introduction: A-WDNETs comprise 32-57% of appendix tumors, diagnosed incidentally in 0.3-0.9% appendectomies (AP). Overall survival is good, but malignant behavior remains controversial.

#1033 Androgens Regulate SMAD Ubiquitination Regulatory Factor-1 Expression and Prostate Cancer Cell Invasion
Introduction: Prostate cancer is the most commonly diagnosed male cancer and is a hormone-driven disease. Androgens have been recognized as a major promoter of PCa development and progression. However, the mechanism of androgen action in PCa, especially in PCa cell invasion remains largely unclear. SMAD ubiquitination regulatory factor-1 (SMURF1) is a C2-WW-HECT-domain E3 ubiquitin ligase that plays important roles in cancer cell metastasis. Whether there is a relationship between androgens and SMURF1 express is not known.

#106 Gastroenteropancreatic neuroendocrine tumors: single institution clinicopathological study
Introduction: Neuroendocrine cells are widely distributed throughout the body, and neoplasms from these dispersed cells can arise at many sites. They are distinguished into two broad categories: 1) Tumors identified as small cell lung carcinomas with biology and natural history of a high-grade malignancy and characteristics of small cell undifferentiated or anaplastic appearance by light microscopy. The WHO categorizes these tumors as poorly-differentiated neuroendocrine carcinomas; 2) Well-defined neuroendocrine tumors (NETs) with variable, but most lyindolent biologic behavior and characteristic well-differentiated histologic features. The majority arise in the gastrointestinal tract and collectively they are referred as gastroenteropancreatic neuroendocrine tumors (GEP/NETs). They include carcinoid tumors, pancreatic islet cell tumors (gastrinoma, insulinoma, glucagonoma, VIPoma, somatostatinoma), paragangliomas, pheochromocytomas, and medullary thyroid carcinomas. The WHO classifies the GEP/NETs as well-differentiated NETs (carcinoid tumors) if they are noninvasive and have benign behavior or uncertain malignant potential. In contrast, GEP/NETs with characteristics of low-grade malignancy with invasion of the muscularis propria or beyond, or metastases, are characterized as well-differentiated neuroendocrine carcinomas (malignant carcinoids). Pancreatic islet cell tumors, whether functioning or not, are classified as well-differentiated NETs or well-differentiated neuroendocrine carcinomas, due to the (depending on) histologic characteristics. The WHO classification for gastroenteropancreatic NETs based on stage (ie size and presence of metastases) and grade (mitotic rate, perineural and lymphovascular invasion, Ki-67 proliferative index) categorizes them as well-differentiated NETs, e.g., carcinoid tumors, or as well-differentiated neuroendocrine carcinomas.

#204 A Proteomic Approach Identifies Novel Proteins Involved in Invasion Mechanisms in Enteroendocrine Carcinomas
Introduction: Enteroendocrine tumors dramatically lack reliable biomarkers to accurately select therapeutic strategy, due to a poor knowledge of molecular mechanisms leading to local invasion and dissemination.

#382 Invaded, Moderately Differentiated Neuroendocrine Carcinoma of Larynx
Introduction: Neuroendocrine neoplasm is extremely unusual and rare in the larynx. It accounts for less than 1% of all laryngeal malignancies. According to the origin, this tumor can be divided into neural and epithelial groups and epithelial origin tumors are further sub-classified based on the degree of differentiation (well-, moderately and poorly differentiated).
