Abstract
Objectives: The present study evaluates the prognostic value of metabolic parameters related to the primary tumor identified in preoperative fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) scans in patients with endometrial cancer (EC).
Material and methods: This study included 120 patients with EC who underwent PET/CT in the preoperative period. The patients’ age, maximum standardized uptake value (SUVmax), SUVmean, metabolic tumor volume (MTV) and the total lesion glycolysis (TLG) value of the primary tumor on PET/CT; as well as the stage, histological subtype, grade and size of the primary EC; the degree of myometrial invasion (MI) cervical invasion (CI), lymphovascular invasion (LVI), lymph node metastasis (LNM) and distant metastasis (DM) were all recorded. The relationship of these factors with progression-free survival (PFS) and overall survival (OS) was evaluated.
Results: The study included 120 patients with EC with a mean age of 62.3 ± 0.02 years. Of the total, 32 patients died around the time of the analysis and 38 patients showed disease progression. The mean OS was 32.7 ± 1.6 months and the mean PFS was 30.5 ± 2.8 months. No significant relationship was identified between the SUVmax, SUVmean, MTV, TLG values, patient age, tumor size, histology, grade and MI degree, and OS or PFS. Disease stage, LVI, CI, LNM and DM were identified as prognostic factors for OS and PFS.
Conclusions: The present study found no significant relationship between preoperative PET parameters in EC and OS and PFS, although prospective studies involving a larger number of patients are required.
