#3022 Diagnostic Accuracy of 68Gallium Positron Emission Tomography (68Ga PET), Endoscopic Ultrasound (EUS) and Computed Tomography in the Assessment of Lymphnode Metastases by Nonfunctioning Pancreatic Neuroendocrine Neoplasms

Introduction: The presence of nodal metastasis is one of the most important predictive factors for recurrence after radical surgery for nonfunctioning Pancreatic Neuroendocrine Neoplasms (NF-PanNEN). Nevertheless, it is not clear which is the best diagnostic examination to identify preoperatively lymphnodal metastasis.

#2777 Tumor-to-Liver Ratio of Ga-68-DOTATOC PET/CT as a Prognostic Parameter in Metastatic, Well-Differentiated Gastroenteropancreatic-Neuroendocrine Tumor Patients Who Received Lanreotide Therapy

Introduction: Lanreotide is a long-acting somatostatin analogue with proven antitumor effect against metastatic, well-differentiated gastroenteropancreatic-neuroendocrine tumors (GEP-NETs). Ga-68-DOTATOC PET/CT is a sensitive imaging technique for NETs by targeting somatostatin receptors.

#2717 64Cu-DOTATATE PET/CT Predicts Progression-Free Survival in Patients with Neuroendocrine Neoplasms

Introduction: The degree of overexpression of somatostatin receptors in patients with neuroendocrine neoplasms (NEN) may reflect tumor differentiation and thus be associated with prognosis. Non-invasive quantification of receptor density is possible by somatostatin receptor imaging (SRI) using positron emission tomography (PET).

#2213 Imaging Modality Depending on the Levels of Tumor Markers

Introduction: 18 F-Fluorodihydroxyphenylalanine(18F)-FDOPA positron emission tomography (PET)/computed tomography (CT) has the advantage of being a noninvasive test and is by far the most promising imaging modality for neuroendocrine tumors (NETs).

#2185 Nonfunctional Pancreatic Neuroendocrine Tumor (NF PNET) Imaging and Evaluation Using 18F-FDG and 68Ga- DOTANOC-PET/CT: Initial Data of a Prospective Study

Introduction: Predicting aggressive behavior of NF PNET still remains controversial. It is known that lymph node metastases are rare but possible also on small (1-2 cm) NF-PNET. Positive 18F-FDG-PET/CT avidity is associated with poor prognosis in NETs.
