¹⁸ F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography as an Effective Diagnostic Workup in Cervical Metastasis of Carcinoma from an Unknown Primary Tumor

Abstract

Although our study was inconclusive due to the small sample size, our results suggest that FDG PET/CT may be an effective diagnostic workup in the cervical metastasis of carcinoma from an unknown primary tumor (UPT). In the present study, SUV(max) of PET/CT in the cervical lymph node may serve as a prognostic factor of cervical metastasis of carcinoma from a UPT based on the limited number of patients. Further studies are needed to confirm these findings.
