#3693 Gallium-68 DOTANOC PET/CT in locally advanced/metastatic WHO grade 2 gastroenteropancreatic neuroendocrine tumors – Clinical and prognostic impact in assessing progression free survival

Introduction: Ga-68 DOTANOC PET/CT based prognostic factors can help in risk-stratification of patients with locally advanced/metastatic GEP-NETs.

#3417 SARS-CoV-2 vaccination site as possible pitfall on somatostatin receptor imaging

Introduction: SARS-CoV-2 (COVID19) vaccinations have shown high efficacy. Therefore, increased chances exist that patients undergoing Peptide Receptor Radionuclide Therapy (PRRT) or radionuclide imaging for Neuroendocrine Tumors (NETs) may have being recently vaccinated.

#2935 Prior Surgical Resection and Ga-68-DOTANOC PET/CT Imaging-Based Parameters: Do These Impact Outcomes in Grade II Gastroentero-Pancreatic Neuroendocrine Tumors (GEP-NETs)

Introduction: Grade 2 GEP-NETs have inherent tumor heterogeneity seen with positive expression of somatostatin (SSTR) and glucose (GLUT) receptors. Prior surgical resection and imaging parameters on Ga-68 DOTANOC PET/C are well-established variable impacting prognosis in well-differentiated grade 1 NETs. Since the degree of differentiation is variable in Grade 2 NETs, these parameters have not been studied.

#517 Initial Experience of Biological Stability and Image Timing of Ga-68 DOTANOC in Somatostatin Receptor (sstr) Expressing Organ and Tumor

Introduction: Since Ga68 DOTATATE has a high affinity to only sstr2 but no affinity to sstr3 and sstr5, Ga68 DOTANOC has been suggested to be a better radioligand with higher affinity to sstr3 and sstr5 and high affinity to sstr2, as well.

#26 Molecular imaging of gastroenteropancreatic neuroendocrine tumours with Ga-68 DOTANOC PET/CT and correlation with an immunhistochemical quantification of somatostatin receptors using novel monoclonal and polyclonal antibodies

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).
