#3048 Somatostatin Analogs or Active Surveillance in Sporadic Non-Functioning Pancreatic Neuroendocrine Tumors

Introduction: Non-functioning (NF), sporadic pancreatic neuroendocrine tumors (pNETs) have usually an indolent behavior, but sometimes show an unpredictable aggressiveness. Surgery is the first-choice for localized tumors >2 cm. Unresectable or metastatic lesions expressing somatostatin receptors (SSTRs) are treated with Somatostatin analogs (SSAs). No evidence of SSAs efficacy exists in tumors ≤2 cm, for which active surveillance has been proposed.

#2984 AGTR1 Is Overexpressed in Neuroendocrine Neoplasms, Regulates Secretion and May Serve as a Target for Molecular Imaging and Therapy

Introduction: Peptide receptor targeting has proven to be a pivotal tool for diagnostic imaging and radioligand therapy of neuroendocrine neoplasms (NENs), which frequently express somatostatin receptors (SSTRs) on their cell surface. However, up to 30 % of NEN patients do not benefit from SSTR-based approaches, others develop a resistance.

#2294 Identification and Validation of the Angiotensin II Receptor Type 1 as a Possible Anti-Cancer Target in Neuroendocrine Tumors

Introduction: Neuroendocrine tumours (NETs) have been found to overexpress somatostatin receptors (SSTRs), which led to the development of somatostatin analogs utilized for diagnostics and therapeutics. However, around 30% of all NETs do not respond to somatostatin based approaches, leading to an interest to find and characterize alternative cell surface targets.

#2048 The Correlation between 68Ga-DOTATATE PET/CT Results and Tumor Proliferation in Patients with Gastroenteropancreatic Neuroendocrine Neoplasms (GEP-NENs)

Introduction: GEP-NENs are heterogeneous neoplasms characterized by overexpression of somatostatin receptors (SSTRs). PET/CT with 68Ga-DOTATATE has shown excellent results for imaging of NENs and has been used more and more widely.
