Abstract

18F-Fluorodeoxyglucose positron emission tomo-graphy and computed tomography (18F-FDG PET/CT) has limited value in well-differentiated neuroendocrine tumors. The value of 18F-FDG PET/CT in non-functioning pancreatic neuroendocrine tumors, which are often poorly differentiated, malignant, and present at an advanced stage, was also thought to be limited. This study was performed to evaluate the clinical value of 18F-FDG PET/CT in assessing non-functioning pancreatic neuroendocrine tumors. From January 2010 to February 2014, a comparable large cohort of patients (31 cases) with non-functioning pancreatic neuroendocrine tumors from Shanghai Cancer Center underwent 18F-FDG PET/CT scans. Demographics and clinical characteristics were retrospectively collected and analyzed for all the patients. Twenty-eight of 31 (90.3%) patients with non-functioning endocrine pancreatic tumors had an elevated 18F-FDG uptake (SUVmax ≥2.5). In addition, 18F-FDG PET/CT visualized 38 of 42 (90.5%) distant metastatic lesions. The 18F-FDG uptake had significant association with tumor size (P=0.012) and TNM stage (P=0.004). The application of 18F-FDG PET/CT has changed the management of 8 cases (8/31, 25.8%). In conclusion, 18F‑FDG PET/CT plays an important role in detecting and staging non-functioning pancreatic neuroendocrine tumors.
