#14 Radioguided surgery in NET: First impression with Ga-68 labeled somatostatin analogues
Introduction: Neuroendocrine tumors (NET) constitute a heterogenous group of neoplasms. The development of Gallium-68-labeled somatostatin analogues, such as DOTA-NOC or DOTA-TOC, PET/CT have dramatically improved the diagnosis of neuroendocrine tumors. Surgery remains the treatment of choice for localized disease as well as metastatic disease. The aims of surgery are: improvement of symptoms, reduction of tumor mass / burden and to give better quality of life to patients. Recurrent laparotomies often lead to multiple adhesions and altered anatomy. So it is increasingly difficult for imaging physicians and surgeons to separate non-malignant from malignant tissue.

#760 Intraoperative Gamma Probe Detection of Metastatic Medullary Thyroid Carcinoma (MTC) with 111In-Pentetreotide
Introduction: MTC is a rare thyroid malignancy representing approximately 5-10% of all thyroid tumors. Early diagnosis and radical surgery are essential to reduce the morbidity and mortality associated with MTC. Somatostatin receptors (SSTRs) expression has been described in MTC with a variable pattern, SSTR2 being prevalent. Although somatostatin analogues demonstrated poor efficacy in the control of MTC growth, SSTR expression can be useful in Nuclear Medicine diagnostic procedures. 111In-pentetreotide scintigraphy and 68Ga-somatostatin analogues PET-CT represent valuable techniques in the detection of MTC, although with a lower sensitivity compared to 18F-DOPA PET-CT.

#193 Paraneoplastic Antigen Ma2 Autoantibodies as Specific Blood Biomarkers for Detection of Early Recurrence of Small Intestine Neuroendocrine Tumors
Introduction: Small intestine neuroendocrine tumors (SI-NETs) are rare fatal cancers. Many patients develop metastatis before diagnosis. There is no available curative treatment for patients with metastasis.

#169 Radio guided surgery in neuroendocrine tumours using 68Ga-labeled somatostatin analogs – a pilot study.
Introduction: Radioguided surgery (RGS) is an intraoperative localizing technique for the detection of cancer tissue using tumor-specific radionuclides.

#2172 Well-Differentiated Neuroendocrine Lesions in Inflammatory Bowel Disease
Introduction: Whether inflammatory Bowel disease (IBD) increases the risk of developing neuroendocrine tumors (NETs) is not clear. NETs are rare in IBD, though one recent report suggests that NETs are 15 times more frequent in patients with Crohn’s disease. Besides NETs, which are discrete mass-forming lesions, microscopic neuroendocrine cell clusters or micronests (NEMs), difficult to measure, are sometimes observed in the lamina propria/muscularis mucosae of IBD patients.

#2301 Trends in Management of Gastro-Intestinal Neuroendocrine Tumors in Inflammatory Bowel Diseases: The Contribute of a Case Series.
Introduction: The risk to develop gastro-intestinal malignancies is higher in patients affected by inflammatory bowel diseases (IBD). Apart from colo-rectal cancer, related to a long standing inflammation, there is a growing evidence of neuroendocrine tumors (NETs) in these patients and a correlation between these two diseases has been postulated. We report four cases of NETs in IBD.

#115 68Ga-DOTA-TATE PET-CT comparison with 99mTc-HYNIC-TOC SPECT-CT in the assessment of the extent of the disease in patients with malignant endocrine tumors: our experience (preliminary results)
Introduction: In neuroendocrine tumors (NETs), the workup is often difficult not only to visualize but also to co-localize the lesions anatomically. Liver and bones are one of the most frequent sites of metastases in patients with endocrine tumors. The Tyr3-octreotate (TATE) somatostatin analogue differs from TOC in that the terminal threonine replaces threoninol. The terminal threonine results in a higher receptor binding (mainly subtype 2) and better internalisation, with the consequence that tumor uptake of the tracer is intense.

#2115 Systemic Markers of Inflammation in Neuroendocrine Tumors (NETs) and Outcomes with Everolimus: A Pooled Analysis from the Randomized, Phase 3 RADIANT-3 and RADIANT-4 Trials
Introduction: NETs are extremely heterogeneous in nature. Despite recent advances, few biomarkers are available to consistently predict prognosis and optimize treatment selection.

#46 Neuroendocrine markers are expressed in human mammary glands
Introduction: Regulatory peptides have previously been detected in epithelial cells of human mammary glands. As these peptides are produced by scattered neuroendocrine cells in the epithelium of other tissues the aim of this study was to investigate whether the mammary glands express molecular markers for neuroendocrine cells.

#159 Detection of cardiac metastases in patients with neuroendocrine tumors: comparison of Ga-68 DOTA-SMS-R PET/CT, cardiac MRI, CT scan and 2D echocardiography
Introduction: Neuroendocrine tumor metastases to the heart have been sparsely reported in literature. There is as of yet no detailed study on the best imaging method for the detection of this rare site of metastases.
