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.
Aim(s): The purpose of this study is to contribute to the validation of a recent study by Cansu G. et al reported tumor grade, positive lymph-nodes, and perineural invasion to be indipendent predictors for recurrence in patients with grade 1 or 2 nonfunctioning pancreatic neuroendocrine tumors (NF-pNET) after curative resection.
Materials and methods: Retrospectively, patients with NF-pNET of our institution were included. Patients with distant metastases, hereditary syndromes, or grade 3 tumors were excluded. Local or distant tumor recurrence was scored. Independent predictors for survival and recurrence were identified using Cox-regression analysis. The recurrence score was developed to predict recurrence within 5 years after curative resection of grade 1 to 2 NF-pNET.
