Description
Summary:To evaluate the usefulness of metabolic parameters obtained by ^sup 18^F-FDG PET/CT for preoperative stratification of high-risk and low-risk endometrial carcinomas. Preoperative ^sup 18^F-FDG PET/CT was performed in 56 women with endometrial cancer. Maximum standardized uptake values (SUVmax), metabolic tumour volume (MTV) and total lesion glycolysis (TLG) of primary tumours were compared with clinicopathological features of surgical specimens. Diagnostic performance in terms of differentiation of low-risk disease (endometrioid histology, histological grade 1 or 2, invasion of less than half of the myometrium, and FIGO stage I) from high-risk disease was assessed. MTV and TLG were significantly higher in patients with higher histological grade (p=0.0026 and p=0.034), larger tumour size (p=0.002 and p=0.0017), lymphovascular space involvement (LVSI; p=0.012 and p=0.0051), myometrial invasion (p=0.027 and p=0.031), cervical stromal invasion (p=0.023 and p=0.014), ovarian metastasis (p=0.00022 and p=0.00034), lymph node metastasis (p
