Role of Combined 68Ga-DOTATOC and 18F-FDG PET-CT in the Diagnostic Workup of Well Differentiated Pancreas Neuroendocrine Tumors (PanNETs): A Surgical Series

#1198

Introduction: PanNETs have a broad spectrum of aggressiveness. Somatostatin-receptor based functional imaging, [68Ga]DOTATOC-PET/CT (GP), is recommended in the diagnostic workup of PanNETs; preliminary evidences show that [18F]FDG-PET/CT (FP) can provide prognostic information.

Aim(s): To assess the role of combined GP and FP in the evaluation of G1-2 PanNETs and to test the correlation between FP positivity and tumor grade.

Materials and methods: Preoperative GP and FP of 35 patients with surgically resected G1-2 PanNETs were evaluated. Correlation between FP positivity (SUV max > 3.5) and tumor grade was assessed.
