#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.

#2243 Somatostatin Analogs (SSAs) as Effective Treatment of Resectable, non Metastatic, non Functioning Pancreatic Neuroendocrine Tumors (NF-pNETs) in Patients Unfit for Surgery. A Case Series.

Introduction: SSAs are used to treat symptomatic functioning pNETs and to prolong progression free survival in metastatic, G1/G2, somatostatin receptor-positive pNETs. Pancreatic surgery is burdened with important morbidity and mortality, especially in patients with increased anaesthesiological risk.

#2228 Prognostic Value of Lymph Node Status and Extent of Lymphadenectomy in Non Functioning Pancreatic Neuroendocrine Tumors: Outcome Analysis from 378 Consecutive Resections in a High-Volume Institution

Introduction: The optimal management of regional lymph nodes during resections of Pancreatic Neuroendocrine Tumors (pNETs) remains controversial. Conflicting data exist on predictors of LN metastases (LNM) and their impact on survival

#2219 24 Hour Urinary 5-Hydroxyindoleacetic Acid Levels in Patients with Non-Functioning Pancreatic Neuroendocrine Tumors

Introduction: The secretion of urinary 5-Hydroxyindoleacetic Acid (u5-HIAA) by non-functioning PNETs (NF-PNET) has rarely been reported, and the data on the association between u5-HIAA levels and disease burden is scant.

#2185 Nonfunctional Pancreatic Neuroendocrine Tumor (NF PNET) Imaging and Evaluation Using 18F-FDG and 68Ga- DOTANOC-PET/CT: Initial Data of a Prospective Study

Introduction: Predicting aggressive behavior of NF PNET still remains controversial. It is known that lymph node metastases are rare but possible also on small (1-2 cm) NF-PNET. Positive 18F-FDG-PET/CT avidity is associated with poor prognosis in NETs.
