#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.

#3030 Targeting CXCR4 and Thioredoxin Reductase in Theranostics of Atypical Carcinoid and Neuroendocrine Carcinoma

Introduction: Atypical carcinoid and small cell lung cancer (SCLC) are currently incurable. There is thus a critical need for new diagnostic and therapeutic strategies for lung neuroendocrine neoplasms (LNEN). Chemokine receptor 4 (CXCR4), a G protein coupled receptor and theranostic target, plays a crucial role in metastases of LNEN. We hypothesize combination of thioredoxin reductase (TR) inhibitor represents a metabolic strategy to enhance cytotoxicity in peptide-receptor radionuclide therapy (PRRT) of LNEN.

#3019 Incomplete Peptide Receptor Radionuclide Therapy Courses - Are We Selecting Our Patients Appropriately?

Introduction: As per recommendations, a Peptide Receptor Radionuclide Therapy (PRRT) with Lu-177 DOTATATE course usually consists of 4 cycles. Patients may discontinue a PRRT course early, either due to progression or toxicity. Limited data are available about predictive factors for PRRT early discontinuation.

#3001 Early Response Assessment for Prediction of Overall Survival after Peptide Receptor Radionuclide Therapy

Introduction: PRRT response assessment is performed using RECIST, yet functional assessment using 68Ga-DOTATATE PET/CT and plasma CgA might give additional information about prediction of overall survival (OS).

#3000 Patients with Somatostatin Receptor Type 2-Negative Neuroendocrine Tumors Have Sustained Inferior Survival Rates in a Propensity Score-Matched Analysis

Introduction: Sufficient expression of somatostatin receptor type 2 (SST2) in neuroendocrine tumors (NETs) is crucial for treatment with unlabelled somatostatin analogues (SSAs), or peptide receptor radionuclide therapy (PRRT) using radio-labelled SSAs. Impaired prognosis has been described for SST2-negative NET patients, however studies comparing matched SST2-positive and -negative subjects are missing.
