#4528 Serum visfatin concentration in metastatic pancreatic and midgut NETs: An exploratory study

Introduction: Neuroendocrine tumours (NETs) are commonly diagnosed at advanced stages due to their diverse and often asymptomatic clinical presentation. Visfatin, an adipocytokine involved in regulating cellular energy homeostasis, inflammation, and tumorigenesis, has been investigated as a potential biomarker in several neoplasms. However, its role in NETs remains unexplored.

#4220 Risk of bowel ischemia in patients with mesenteric neuroendocrine tumors after treatment with 177Lutetium-DOTATATE

Introduction: 177Lutetium (Lu)-DOTATATE is an effective treatment for metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs). However, radiation can cause transient inflammation/swelling of tumors which can result in toxicity. Treatment-related small bowel obstruction associated with mesenteric or peritoneal disease has been described.

#4059 Evaluation of Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR) and Systemic Immune–Inflammation Index (SII) as potential biomarkers in patients with sporadic pancreatic neuroendocrine tumors (pNET)

Introduction: Pancreatic neuroendocrine tumors (pNETs) are rare neoplasm in which the investigation of new biomarkers is essential. An elevated Neutrophile to Lymphocyte Ratio (NLR), Platelet to Lymphocyte Ratio (PLR) and Systemic Immune-Inflammation Index (SII) has been proposed as a negative prognostic factor in several neoplasms, but their role in pNET is unclear.

#3726 Inflammation based index and tumor heterogeneity on pretherapeutic 68Ga DOTATOC PET/CT predict outcome in midgut neuroendocrine tumor patients treated with 177Lu-oxodotreotide

Introduction: Peptide receptor radionuclide therapy with 177Lu oxodotreotide (LuPRRT) is a standard treatment for the management of patients with inoperable metastatic well-differentiated neuroendocrine tumors of the midgut (iNET). As LuPRRT becomes widely used for a heterogeneous population of NET patients, practical predictive biomarkers are needed. Inflammation based index (IBI) derived from serum C reactive protein and albumin is associated with progression free survival (PFS) and overall survival (OS) in patients with PRRT for NETs. Ga-68 DOTATOC PET/CT (DOTAPET) assessment of lesion heterogeneity was predictive for response to PRRT.
