#1071 Pathological Factors Predicting Recurrence of the Non-Functioning Pancreatic NET after Resection
Introduction: The usefulness of the WHO 2010 classification for surgeons has not been elucidated, since the criteria is defined by cell growth with Ki67 and may not represent invasiveness of the tumor as well as the recurrence type (liver metastasis or lymph node metastasis)

#1428 Factors Affecting Recurrences of the Non-functioning Pancreatic NET After Resection
Introduction: In 2010, WHO classification has been modified. However, the usefulness of the criteria for surgeons has not been elucidated, because the criteria is defined by cell growth represented by Ki67 for overall survival and may not represent invasiveness of the tumor.

#1560 Cannabinoids as Inhibitor of Tumour Growth and Invasiveness in Small Intestine Neuroendocrine Cancer
Introduction: Tumour cell invasion and proliferation is a key factor for the prognosis and progression of cancer. A recent study revealed that cannabinoids can inhibit tumour invasion and proliferation in breast cancer through the down-regulation of ID-1, an inhibitor of helix-turn-helix transcription factors.

#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.

#191 Immunohistochemical Analysis of Epithelial-Mesenchymal Transition Markers in Neuroendocrine Tumors of the Lung
Introduction: The increased motility and invasiveness of cancer cells in the first phase of metastasis are reminiscent of epithelial–mesenchymal transition (EMT) during embryonic development.

#986 Expression of the Truncated Somatostatin Receptor Variant Sstr5TMD4 in Medullary Thyroid Carcinoma
Introduction: Medullary thyroid carcinoma (MTC) is a rare tumor originating from thyroid parafollicular C cell. The only available treatment is surgical resection, which is not always feasible. Somatostatin and its receptors are expressed both in normal human thyroid C cells and in MTC, but their role has not been fully elucidated. The discovery of a truncated isoform of Sstr5, Sstr5TMD4, associated with increased invasiveness and aggressiveness in breast cancer, has opened new insight in the role of Sstr in cancers.

#1115 Cancer Stem Cells in Small Intestine Neuroendocrine Cell Line P-STS: Isolation and Molecular Characterisation
Introduction: Cancer stem cells (CSCs) represent a small subpopulation of tumour cells responsible for invasive tumour growth. Even though the presence of CSCs in neuroendocrine tumours is documented, their role in neuroendocrine tumourigenesis and metastasis is not defined as yet.

#1523 Multiregion Analysis Reveal Evolutionary Patterns and a Chromosomal Instability Signature in Pancreatic Neuroendocrine Tumours
Introduction: Pancreatic neuroendocrine tumors (PNETs) are potentially lethal diseases that show variable degrees of proliferation and invasiveness. Although genetic subgroups have been suggested to give prognostic information the impact of clonal evolution to the development and outcome of PNETs remains unexplored.

#1716 Trans-Anal Minimally Invasive Surgery (TAMIS) for Completion Local Excision of Well-Differentiated Rectal Neuroendocrine Tumours.
Introduction: Rectal NETs (R-NETs) <2cm are often amenable to endoscopic resection, but initial resections are often incomplete, and extended monitoring or radical surgery may then be required. Trans-anal minimally invasive surgery (TAMIS) allows resection of rectal tumours while reducing surgical morbidity. Data on its use in R-NETs is scant.

#2086 miRNA Expression Defines Novel Subgroups of Small Intestinal Neuroendocrine Tumors
Introduction: Epigenetic dysregulation frequently occurs in cancers. Here we present the largest survival related miRNA profiling study to date of small intestinal neuroendocrine tumors (SI-NETs).
