#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.

#3047 Functional Consequence of β-Arrestin 1 Gene Knock-Out in Pancreatic Neuroendocrine Tumor Cell Line BON-1

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.

#3033 First-in-Korea Clinical Trial of Lu-177-DOTATATE in Patients with Inoperable, Progressive Somatostatin Receptor-Positive, Metastatic or Locally Advanced Neuroendocrine Tumor (SNU-KB-01)

Introduction: Peptide receptor radionuclide therapy (PRRT) based on Lu-177 DOTATATE is currently used worldwide as a treatment option for neuroendocrine tumor patients. But until now, no PRRT has been approved by the Korea Food and Drug Administration (KFDA). Thus, neuroendocrine tumor patients in Korea have severely limited access to the treatment. To provide treatment opportunities, we have planned a First-in-Korea phase I clinical trial of SNU-KB-01, no-carrier added Lu-177 labeled DOTATATE.
