#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.

#2197 Tumor Necrosis of Primary Malignancy Affects Survival and Outcome in Patients with Liver Metastases from Neuroendocrine Tumors

Introduction: Reliable biomarkers represent a crucial unmet need in the management of neuroendocrine tumors. Tumor necrosis has been suggested to have a prognostic value in selected solid tumors but is not included in established WHO NET Grading Systems. However, little is known regarding the influence of tumor necrosis on tumor progression and prognosis in patients with liver metastasis from neuroendocrine tumors.

#1677 A New Scoring System to Predict Recurrent Disease in Grade 1 and 2 Non-Functional Pancreatic Neuroendocrine Tumors.

Introduction: Surgical resection is the preferred treatment for NF-pNET, however recurrence still occurs frequently after curative surgery, worsening prognosis of patients.

#1633 The Preoperative Blood Lymphocyte-To-Monocyte Ratio Acts As a Superior Prognostic Factor and Predicts Tumor Metastasis in Gastric Neuroendocrine Neoplasms after Surgery

Introduction: A low lymphocyte-to-monocyte ratio (LMR) has been reported to be a predictor of poor survival in patients with various cancers but has not been examined in patients with gastric neuroendocrine neoplasms (g-NENs).
