#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.

#2866 Extrahepatic 68Ga-DOTATATE-Avid Tumor Volume and Serum Chromogranin A Predict Short-Term Outcome of 177Lu-DOTATATE in Late-Stage Metastatic Gastroenteropancreatic Neuroendocrine Tumors

Introduction: 177Lu-DOTATATE is an effective therapy for somatostatin receptor-positive neuroendocrine tumors (NETs). Often enough 177Lu-DOTATATE is used as the last treatment resort in advanced NET.

#2855 Whole Exome Sequencing Reveals the Monoclonal Origin of Gastric Mixed Adenoneuroendocrine Carcinomas

Introduction: Gastric mixed adenoneuroendocrine carcinomas (g-MANECs) are rare neoplasms consisting of adenocarcinoma and neuroendocrine neoplastic components. G-MANECs show more malignant characteristics than gastric adenocarcinomas, while molecular mechanisms underlying the co-existence of the two components remains unknown.

#2838 Accidental Injection of Unlabeled Lu-177 Caused Catastrophic Consequences in Patients with Neuroendocrine Tumor

Introduction: Since Lu-177 DOTATATE treatment is not approved in South Korea, patients with neuroendocrine tumors were sent to Germany and Malaysia for the treatment.
