ABSTRACT
Objective:To retrospectively evaluate whole body ~(18)F-FDG PET/CT in depicting the primary tomors in cervical metastatic adenocarcinoma of unknown primary site.Methods:Seventeen patients were included and underwent whole body PET/CT imaging.The primary tumors and metastases were detected by visual evaluation and measurements of standardized uptake values.The PET/CT impression was verified by histopathology and(or)follow-up.Results:In 17 patienis,primary tumors of 13 patients were confirmed by pathological or clinical follow-up.Among them,8 were in the lung,1 in breast,1 in renal,2 in colon and 1 in cervix.Among the other 4 cases,3 cases were correctly diagnosed as malignant lymphoma finally by PET/CT instead of metastatic adenoearcinoma previously.The sensitivity,specificity and accuracy of PET/CT in were 92.3%,75.0% and 88.2%,identifying primary tumors respectively.After PET/CT examination,10 patients(58.8%)were detected additional metastatic lesions which were missed previously.Conclusion:Whole body ~(18)F-FDG PET/CT may be of relatively higher value in identifying the primary tumor of cervical metastatic adenocarcinoma from unknown primary site.It also may display tumor involvement extent.
