#2731 177Lu-DOTATATE Plus 166Ho-Radioembolization in Patients with Neuroendocrine Tumours; A Single Center, Prospective, Interventional, Non-Comparative, Open Label, Phase II Study (HEPAR PLuS Study)
Introduction: The liver is the most commonly affected organ in metastatic neuroendocrine disease and is the most incriminating factor for patient survival. Additional treatment of liver disease with radioembolization may improve outcome in NET patients with bulky residual liver disease after PRRT.

#2847 Surgical and Survival Outcomes of Early Peptide Receptor Radionuclide Therapy for Downstaging Locally Advanced or Oligometastatic Pancreatic Neuroendocrine Neoplasms
Introduction: Pancreatic neuroendocrine neoplasm (pNEN) patients often present with locally advanced or metastatic disease. The objective response rate of peptide receptor radionuclide therapy (PRRT) in pNENs is 55%. Therefore, PRRT may be a possibility for patients who are not eligible for upfront curative surgery.

#2738 Patient-Derived Organoid Models of Human Neuroendocrine Carcinoma
Introduction: Gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC) is a poorly understood disease with limited treatment options. Due to its low incidence and wide tissue distribution few representative preclinical models are available

#2976 Incidence of Appendiceal NEN and Adherence to Pathological Classification Rules and Treatment Guidelines: Results of the Population Based Cancer Registry in Belgium
Introduction: Classification of appendiceal neuroendocrine neoplasms (aNEN) changed significantly over the years and treatment algorithm remains a matter of debate.

#2772 Vitamin Supplementation and a Personalized Diet in Patients with Neuroendocrine Tumors: The DIVIT Study
Introduction: Patients with neuroendocrine tumors (NETs) are at risk for vitamin deficiencies and poor nutritional status due to excessive serotonin production, diarrhea, previous gastrointestinal surgery, and/or treatment with somatostatin analogues (SSA). Little knowledge exists about vitamin deficiency and how patients should be supported for the deficiencies they develop during their long-lasting disease.

#2875 Immunotherapy as Second-line Treatment in Grade 3 Neuroendocrine Carcinomas: A Prospective Case Series from an ENETS Center of Excellence
Introduction: Metastatic WHO grade 3 extra-pulmonary neuroendocrine carcinomas (EP-NEC) have a poor prognosis and optimal treatment after first-line platinum-etoposide chemotherapy remains unclear. A recent, small phase II study combining ipilimumab and nivolumab showed promising results

#2902 DNA Methylation Analysis of the PDX1 Gene Can Be Used for PNET Subtyping and Has a Possible Prognostic Value
Introduction: Estimating prognosis of pancreatic neuroendocrine tumor (PNET) patients remains challenging. Mutation status of DAXX/ATRX/MEN1, histone modification patterns and immunohistochemistry for relevant transcription factors, including PDX1, were recently used to perform subtyping and distinguished two main types, A and B. These subtypes are linked to cell-of-origin and associated with clinical outcome.

#2905 DNA Methyltransferase Inhibitor Hydralazine Induces Upregulation of Somatostatin Type 2 Receptors in Human Neuroendocrine Tumor Cells
Introduction: Epidrugs like DNA methyltransferase inhibitors (DNMTi) can increase somatostatin receptor type 2 (SST2) expression in neuroendocrine tumor (NET) cells in vitro and in vivo. This effect could be used for NET patients with low SST2 expression who are currently ineligible for somatostatin analogue (SSA) treatment. However, the DNMTi known to stimulate SST2 have either a high toxicity profile or are not yet approved.

#2988 Epigenetic Treatment with Histone Deacetylase Inhibitor Enhances Uptake of [111In]In-DOTA-TATE by Increased SST2 Expression on Neuroendocrine Tumor Cells
Introduction: The somatostatin-2 receptor (SST2) is a target for peptide receptor radionuclide therapy (PRRT) in neuroendocrine tumors (NETs). By using epigenetic drugs, which can regulate gene transcription, PRRT efficacy may be further improved due to enhanced SST2 expression.
