#3010 International Validation of a Nomogram to Predict Recurrence after Resection of Grade 1 and 2 Pancreatic Neuroendocrine Tumors

Introduction: A prediction model to predict recurrence within 5 years after surgery for nonfunctional pancreatic neuroendocrine tumors (PanNets) was recently published. This model includes WHO tumor grade, lymph node status and perineural invasion as predictors.

#2965 Molecular Signature of Rectal Neuroendocrine Neoplasia

Introduction: Rectal neuroendocrine tumors are rare neuroendocrine neoplasias (NEN). Little is known about prevalence and type of somatostatin receptor subtypes (sstr) expression and somatic mutations in relation to long-term clinical outcome.

#2961 Our Experience Using a New Scoring System to Detect Disease Recurrence after Curative Surgical Resection of Well-Differentiated Pancreatic Neuroendocrine Tumors

Introduction: For patients with nonfunctioning pNET  ≥20 mm in size without distant metastasis, complete surgical resection is recommended as the primary curative strategy. Effective follow‐up programs are designed to detect recurrence at an early stage, given that treatment of limited disease has the most favorable outcome. However, data on post‐curative surgical recurrence remains limited, making it challenging to determine the best follow‐up strategy and to detect the best treatment options as an adjuvant therapy for selected patients.

#2848 Correlation between Clinicopathological Features and Distant Metastases in Pancreatic Neuroendocrine Neoplasm: A National Multicenter 10-Year Retrospective Study

Introduction: The incidence of pancreatic neuroendocrine neoplasm (PNEN) is increasing, and the prognosis of patients with PNEN is quite different.So, it is of great significance to study the effect of different pathological features on the prognosis of patients with PNEN.

#2805 Small Bowel Neuroendocrine Tumor Metastases: Comparison of Contrast-Enhanced Computed Tomography and 68Ga-DOTATATE PET/CT

Introduction: Most gastrointestinal neuroendocrine tumors (GI-NETs) involve the small intestine (38%) and about 50% of patients present with regional or distant metastases at time of diagnosis [2]. 68Ga-DOTATATE PET/CT provides improved sensitivity and specificity compared to traditional nuclear medicine techniques [4]. However, there is relatively less data comparing performance of 68Ga-DOTATATE PET/CT with contrast-enhanced CT (CECT).
