#2844 Rectal Neuroendocrine Tumor with Chromogranin Expression Is Associated with Aggressive Clinical Behavior and Worse Prognosis
Introduction: Although rectal neuroendocrine tumors (NETs) with L-cell phenotype and small tumor size generally had better clinical behavior, the new 2019 WHO classification classified all rectal NETs are malignant without considering L-cell phenotype and small tumor size. Therefore, identifying biomarkers of rectal NETs is important to stratify the clinical behavior of rectal NETs.

#3031 Primitive Peripheral Neuroectodermal Tumor: Case Report
Introduction: Primitive neuroectodermal tumors belong to the family of Ewing sarcomatous tumors, all derived from the same stem cell. The cells of the neural crest are believed to be at the origin of these tumors. The predilection sites of these sarcomas are para-vertebral region, chest wall and the distal ends. The positive diagnosis of primary neuroectodermal tumors requires the contribution of histopathology, immunohistochemistry and cytogenetics.

#87 Alterations of E-cadherin, beta-catenin and caveolin-1 expression in gastroenteropancreatic neuroendocrine tumors
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP NETs) comprise a heterogeneous group of neoplasm with different histological patterns and biological behavior. Only limited information is available on immunohistochemical prognostic factors of disease. Alterations in the cell-cell adhesion system are closely associated with cell invasion and metastasis in many malignancies, including those of endocrine origin. Abnormal expression of E-cadherin and beta-catenin has been reported to play an important role in these processes. Caveolin-1 has recently been identified as a tumor metastasis modifier factor, which might increase the cell metastasis potential through the interaction with E-cadherin. However, the role of caveolin-1 in GEP NETs cell invasion remains unknown.

#182 Ki-67 (MIB-1) Proliferative Activity and Beta-Catenin Immunoexpression in Liver Metastases of Gastroenteropancreatic Neuroendocrine Tumors
Introduction: Assessment of liver metastases biology features associated with cell proliferation and adhesion has a strong prognostic impact in patients with gastroenteropancreatic (GEP) neuroendocrine carcinomas.

#508 Differential Expression of Markers in a Midgut Carcinoid Tissue Microarray
Introduction: Molecular mechanisms driving well-differentiated midgut carcinoid (MGC) tumors are not well-established. To pursue higher resolution tumor diagnostics, we studied a panel of markers for their expression in MGC, including: serotonin, FGF2, b-catenin, and E-cadherin, in primary, lymph node, and liver metastases.

#581 Loss of Succinate Dehydrogenase (SDHB) Expression in Midgut Carcinoids as Prognostic Factor: a New Marker of Personalized Cancer Medicine in Neuroendocrine Tumors?
Introduction: Gene mutations of SDH complex have been involved in the pathogenesis of cancer cells. These mutations are often associated with loss of activity of SDH subunity B and overexpression of HIF-1a, which play a central role in angiogenesis.

#645 Loss of Succinate Dehydrogenase (SDHB) in Midgut Carcinoids as Prognostic Factor: A New Marker of Personalized Cancer Medicine in Neuroendocrine Tumors?
Introduction: Gene mutations of the succinate dehydrogenase (SDH) complex are involved in the pathogenesis of cancer cells and play a pivotal role in angiogenesis and cell proliferation. The immunoistochemical (IHC) loss of SDHB is a marker of malignancy in pheocromocytomas and paragangliomas.

#647 Reducing the Risk of Tuberculosis Reactivation when Administering Everolimus for a Pancreatic Neuroendocrine Tumor: A Case Report
Introduction: Everolimus can potentially reactivate tuberculosis (TB) through immunosuppression. This was recently reported to have occurred in a kidney transplant recipient. To date, no clear strategy has been developed for reducing the risk of TB reactivation during everolimus treatment.
