#88 EpCam expression and detection of circulating tumor cells in neuroendocrine tumors
Introduction: Using the CellSearchTM system, circulating tumor cells (CTCs) can be reproducibly enumerated according to expression of EpCAM and cytokeratins 8, 18 or 19 and the absence of the haemopoietic marker CD45. The number of CTCs detected in 7.5 mls blood has been shown to correlate with prognosis in breast, colon and prostate cancer and can predict response to therapy. Neuroendocrine tumors (NETs) have not previously been reported to express EpCAM and have not been systematically assessed for presence of CTCs. We have therefore explored the expression of EpCAM in NETs and the detection of NET cells in the circulation.

#250 Circulating Tumor Cells (CTCs) Correlate with Overall Survival in Neuroendocrine Tumors (NETs)
Introduction: Using the CellSearchTM system, circulating tumor cells (CTCs) can be reproducibly enumerated. We have previously shown that CTCs are detectable in NETs and associated with progressive disease.

#722 Isolation and Whole Genome Amplification of Single Circulating Tumor Cells in Neuroendocrine Tumors: A Pilot Study
Introduction: We have previously demonstrated that Circulating Tumor Cells (CTCs) can be detected in patients with neuroendocrine tumors (NET) and that their presence is prognostic. Downstream analysis of CTCs provides an opportunity to explore their potential as biomarker for targeted therapy. Here we present initial data which demonstrates that molecular profiling can be successfully performed on single CTCs from patients with NETs

#1364 Clinical Utility of EpCAM-positive Circulating Tumor Cells in Neuroendocrine Neoplasms Using the CellSearch Platform
Introduction: Circulating tumor cells are captured to predict the prognosis of patients in many types of cancers, but reports are rare on clinical utility and tumor cell shedding in neuroendocrine neoplasms (NENs).

#19 Antitumor activity of Pasireotide (SOM230) alone and in combination with Everolimus (RAD001) in DU-145 human prostate cancer model
Introduction: Pasireotide (SOM230) is a novel multi-receptor ligand somatostatin analogue with high affinity for somatostatin receptor subtypes sst1,2,3 and sst5. Like octreotide, which binds primarily to sst2, it inhibits hypersecretion of hormones from patients with functional pituitary tumors and gastroenteropancreatic neuroendocrine (GEP/NET) tumors. In addition, tumor shrinkage has been observed with both compounds in patients with acromegaly, Cushing’s disease and GEP/NETs, but its tumor-reducing mechanism of action has so far not been revealed. In patients with breast and liver cancer, octreotide had little or no antitumor activity.

#922 Comparison of the Novel Cell Detector Method with Cell Search Technology in the Isolation of Circulating Tumor Cells in Neuroendocrine Tumors
Introduction: Circulating Tumor Cells (CTCs) have been detected in patients with neuroendocrine tumors (NET) using the CellSearch platform. Their presence is associated with a worse clinical outcome but less than 50% patients have detectable cells. The GILUPI Cell Detector is an EpCAM coated wire that is inserted into a vein and has been developed to increase capture of CTCs.

#2162 Single Cell Copy Number Variation Analysis (CNV) of Circulating Tumor Cells (CTCs) in Neuroendocrine Tumor (NET) Patients
Introduction: The identification and characterization of CTCs as part of a minimally invasive “liquid biopsy” provides an opportunity to explore NET biology, identify therapeutic targets and investigate tumour heterogeneity.

#2022 CXCR4 Expression on Circulating Tumor Cells (CTCs) and Their Association with Bone Metastases in Patients with Neuroendocrine Tumors (NET)
Introduction: Bone metastases have been described in up to 32% of NET patients and are associated with a worse clinical outcome. Overexpression of CXCR4 in primary tumors appears predictive of skeletal involvement.

#757 Circulating Endothelial Cells in Neuroendocrine Tumors
Introduction: Circulating endothelial cells (CECs) are mature endothelial cells that are shed into the bloodstream. We hypothesised that neuroendocrine tumors (NETs), being highly vascular, may shed more CECs into the circulation, and that changes in their number may serve as a biomarker for anti-angiogenic therapy.

#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.
