Detection Limitation of Occult NET Using Gallium-68 Dotatoc Scan Plus FDG PET Abstract #887

Introduction: The modalities detection of gastroenteropancreatic neuroendocrine tumors (GEP-NET) includes sonogram, abdominal CT and MRI, but the detection rate is limited. Iodium-111 Octreotide scan is another choice. Ga-68 Dotatoc scan is very rapid and more sensitive than Octreoscan. The Ga-68 Dotatoc scan plus FDG-PET is useful for detecting active NETs.
Aim(s): The detection rate and affect factors of Ga-68 Dotatoc scan plus FDG-PET were studied.
Materials and methods: Twelve cases with elevated chromogranin A and failure to detect NET after the classic image examinations were included in this study. Ga-68 Octreotate scans plus FDG-PET and MRI were performed. The exclusive criteria were lactating or pregnancy, fasting sugar higher than 200 mg%, and GFR less than 30 ml/min. Their clinical data were recorded for comparison.

#390 An Increasing Incidence of GEP-NETs in Chengdu City with a Population of 14 Million in China
Introduction: The annual incidence of GEP-NETs in China is still unclear. All histopathology and cytopathology reports have yet to be collected in a national archive. No national or regional survey on GEP-NETs has been approved. West China Hospital (WCH), a university hospital located in Chengdu City with a population of 14 million, has established a series of databases in recent years.

Introduction: Receptor PET/CT with somatostatin analogues marked with Gallium-68 (SMS-R-PET/CT) is currently the golden standard in diagnosing gastroenteropancreatic neuroendocrine tumors (GEP-NET), which are known for an overexpression of somatostatin receptors (SSTRs).
