Detection of Liver Metastases and Prognostic Value of Functional and Anatomical Imaging in Patients with Neuroendocrine Tumors Abstract #472

Introduction: Liver metastases (LM) are frequent in patients with neuroendocrine tumors (NETs) and are associated with decreased overall survival (OS). Several treatment options are available depending on degree, localization, size and number of LM. For optimal choice of treatment and correct staging, accurate imaging modalities are crucial.
Aim(s): To assess and compare several different imaging options available for patients with NETs and to evaluate if presence of LM was associated with decreased OS.
Materials and methods: Ninety-two prospectively enrolled patients with histologically verified NETs underwent 111In-DTPA-Octreotide scintigraphy (SRS), 123I-Metaiodobenzylguanidine(MIBG) scintigraphy, 18F-Fluorodeoxyglucose-PET(FDG-PET) and computer tomography(CT). OS based on presence of LM was estimated by the Kaplan-Meier method. Mean follow-up time from FDG-PET was 31 months.

#138 The use of F-18-FDG-PET for patients with neuroendocrine tumors
Introduction: Neoplastic tissue exhibits high glucose utilization, which can be imaged by 18F-Fluorodeoxyglucose-positron emission tomography (FDG-PET). Whether FDG-PET is useful for neuroendocrine (NE) tumors, however, is questionable, due to the slow growth rate often observed in these tumors.

#468 mir-129-5p and Let-7 are Down-Regulated in Carcinoid Tumors
Introduction: miRNAs are small non-coding RNAs that post-transcriptionally regulate gene expression by binding to complementary sequences on target mRNAs and their expression is often dysregulated in cancer.

#470 Overall Survival of Well-Differentiated Neuroendocrine Tumors Evaluated by F-18-FDG-PET
Introduction: Today, grading, and thereby choice of treatment strategy for patients with neuroendocrine (NE) tumors, is mainly based on the proliferation index, Ki-67. As a supplement to this pathological evaluation, a whole body image analysis could be of value.

Introduction: Accurate grading of patients with neuroendocrine tumors (NETs) is essential for risk stratification and optimal choice of therapy. Currently, WHO grading is based on histo-pathologically assessed degree of tumor proliferation.
