Objective: To investigate the prognostic value of metabolic tumor volume (MTV) and totallesion glycolysis (TLG), measured by preoperative 18F-fluorodeoxyglucose positron emissiontomography/computed tomography (18F-FDG PET/CT), in risk stratification of patients withendometrial carcinoma (EC). Methods: The patients with pathological diagnosis of EC who underwent preoperative18F-FDG PET/CT imaging were retrospectively selected for analysis of the prognostic valuesof PET parameters in risk classification and lymph node metastases (LNMs). Receiveroperating-characteristic analysis was used to analyze the correlation of PET parameters cutoffvalues with deep myometrial invasion (MI), lymphovascular space involvement and LNM forprognostic values in risk stratification. Results: The sensitivity, specificity, positive predictive value, negative predictive value andaccuracy for detection of LNM are 83.3%, 99.7%, 90.9%, 99.5% and 99.2%, respectively. TheMTV and TLG of primary lesion of EC in the patients with LNM are notably higher than thosein patients without LNM, p<0.010. The MTV and TLG of the EC primary lesions in high-riskpatients are significantly higher than those in low-risk patients (p<0.010), but the maximumstandardized uptake value (SUVmax) is not. The MTV and TLG of primary lesions weresuperior to SUVmax for predicting of deep MI, LNM and high-risk of EC (p<0.005). Conclusion: MTV and TLG of primary lesions are more valuable in predicting riskstratification of EC patients. Preoperative 18F-FDG PET/CT imaging is useful in predictingthe LNM of EC and may help guide pelvic lymphadenectomy to avoid unnecessary pelviclymphadenectomy in EC patients with low-risk stratification.
