#2987 68Ga-DOTATOC PET/CT as Tool for Diagnosis and Decision-Making Process of Neuroendocrine Tumors

Introduction: Primary tumors in some patients with metastatic neuroendocrine tumors (NET) cannot be found by conventional imaging as CT, MRI and scintigraphy. 68Ga-DOTATOC PET/CT (68Ga-PET) appears to have superior sensitivity, specifity, and better resolution than 99mTC-octreotide SPECT/TC (SSTR scintigraphy) and can improve decision-making process, however its cost is higher, and its availability is limited.

#2897 Comparison of 68Ga-DOTATATE PET/CT for Assessment of Response to Peptide Receptor Radionuclide Therapy after 2 and 4 Cycles of 177Lu-DOTATATE: Preliminary Single Academic Center Experience

Introduction: Peptide receptor radionuclide therapy (PRRT) usually leads to stable rather than decreased lesion size in neuroendocrine tumors (NETs), therefore RECIST criteria are not used to assess early response to treatment.

#1690 18F-FDG-PET to Discriminate Biologically Malignant Pancreatic Neuroendocrine Tumors

Introduction: 18F-FDG-PET is widely used to detect malignant tumors. However, the efficacy for pancreatic neuroendocrine tumors (PNETs) is reported to be limited in the clinical practice.

#1370 68Ga-DOTATOC PET and Gene Expression Profile in Patients with Neuroendocrine Carcinomas

Introduction: Somatostatin receptor expression on both protein and gene expression levels were compared with in vivo 68Ga-DOTATOC PET/CT in patients with neuroendocrine carcinomas (NEC).

#1158 A Phase II Study of Everolimus in Patients with FDG-PET Positive Intermediate Grade (Ki67 3-20%) Pancreatic Neuroendocrine Tumor

Introduction: The RADIANT-3 trial showed Everolimus (EV), as active in patients (pts) with progressive well/intermediate grade PNETs. Intermediate/grade 2 (Ki67 3-20%) PNETs have variable biology. FDG-PET avidity is an independent negative factor for survival, consistent with aggressive disease biology- but such imaging is not used to select treatment as in the case of the RADIANT 3 trial.
