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.

Introduction: An important limiting factor influencing treatment efficacy of neuroendocrine tumors (NETs) with somatostatin analogs (SSA) is the availability of somatostatin receptors (SSTR) on NETs. While downregulation or altered pattern of SSTR expression are important considerations, receptor internalization/desensitization by β-arrestins may be a crucial contributing factor. Interestingly, our previous study showed a preferential higher expression of β-arrestin 1 (ARRB1), in gastroenteropancreatic NETS (GEP-NETs) compared to pituitary adenomas.

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.
