#4515 Prognostic factors for survival in patients with metastatic small intestinal neuroendocrine tumours undergoing primary tumour resection

Introduction: Although guidelines recommend primary tumour resection in metastatic small intestinal neuroendocrine tumours (SI-NETs) to manage symptoms and complications, the survival benefit and optimal surgical approach remain unclear.

#4430 Long-term prognosis of parenchyma-sparing vs. oncologic resections for distal pancreatic non-functional neuroendocrine tumours ≤ 3cm: A real-world data study (CSPAC-NEN-5)

Introduction: Studies show that parenchyma-sparing resections (PSR) for small, non-functional pancreatic neuroendocrine tumours (NF-pNETs) provide long-term outcomes similar to oncologic resections (OR). However, these studies have not fully considered location-based differences in surgical approach and lymphatic drainage.

#4394 Application of somatostatin receptor PET/CT in assisting preoperative lymph node evaluation and surgical decision-making for duodenal and pancreatic neuroendocrine neoplasms

Introduction: Preoperative precise staging of lymph nodes is crucial for determining surgical approach and extent for duodenal and pancreatic neuroendocrine neoplasms (DP-NENs), especially for small (≤2cm) DP-NENs.

#4129 Validation of a radiomics model to predict symptoms complications from small intestinal NET mesenteric metastases – Preliminary report

Introduction: The development of mesenteric metastases and associated mesenteric fibrosis in small intestinal neuroendocrine tumors (SI-NET) can cause significant complications and have implications in patients’ survival. CT is suboptimal for accurate assessment of the degree of fibrosis and prediction of complications. A better model is needed, therefore, in order to select patients who may benefit from a prophylactic surgical approach in the mesentery. Recently the promising role of a radiomics model was shown as a predictive tool for development of complications of mesenteric metastases/fibrosis in 68 patients.

#4040 Surgery of small bowel neuroendocrine tumors: 10 years’ experience at a tertiary centre

Introduction: Small bowel neuroendocrine tumors are often found when they have already spread. These tumors are hard to treat, and there are many different treatments.
