Introduction: This study evaluated the role of F-18-fluorodeoxyglucose (FDG) positron emission tomography/CT (PET/CT) in the detection of lymph node metastases and the association between uterine maximum standardized uptake values (SUVmax) and the histopathological features in endometrial cancer patients. Materials and Methods: Patients with endometrioid endometrial cancer underwent preoperative F-18-FDG PET/CT imaging and were staged surgically. (18)trial invasion, grade and cervical stromal involvement. Conclusions: (18) F-FDG PET/CT has limited sensitivity and accuracy in detecting lymph node metastasis. Therefore, as of now, it is not accepted as a modality that can replace lymphadenectomy. SUVmax values can predict high-risk factors. (C) 2016 S. Karger AG, BaselF-FDG PET/CT findings were compared with final pathology reports. Grade 3 histology or grade 2 histology with myometrial invasion >= 50% was established as a high risk feature. Results: One hundred and eleven patients were analysed. Sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of F-18-FDG PET/CT in the detection of lymph node metastasis in all patients (n = 111) were 67, 96, 93, 60 and 97%, respectively. In the highrisk group, sensitivity, specificity, accuracy, PPV and NPV of 18 F-FDG PET/CT were 75, 92, 91, 60 and 96%, respectively. Uterine SUVmax was found to be associated with myome-trial invasion, grade and cervical stromal involvement. Conclusions: 18 F-FDG PET/CT has limited sensitivity and accuracy in detecting lymph node metastasis. Therefore, as of now, it is not accepted as a modality that can replace lymphadenectomy. SUVmax values can predict high-risk factors. (C) 2016 S.Karger AG, Basel
