Prognostic Value of FDG-PET/CT Total Lesion Glycolysis for Patients with Resectable Distal Bile Duct Adenocarcinoma

Anticancer Res. 2015 Dec;35(12):6985-91.

Abstract

Aim: We investigated the prognostic value of clinicopathological factors in patients with a distal bile duct adenocarcinoma after curative resection.

Patients and methods: This retrospective study included 25 patients who underwent (18)F-fluorodeoxyglucose positron-emission tomography/computed tomography (FDG-PET/CT) before surgery. The maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were measured using FDG-PET/CT. FDG-PET/CT parameters and other clinicopathological factors were assessed to evaluate survival.

Results: Univariate survival analysis showed that high TLG, high MTV, and high SUVmax were significant prognostic predictors for poor overall survival. For progression-free survival, high TLG and large tumor size were significant predictors for a poor prognosis. After multivariate survival analysis, only high TLG was an independent prognostic predictor for poor overall survival (p=0.025).

Conclusion: Preoperative assessment of TLG by FDG-PET/CT might be a useful prognostic predictor in patients with a distal bile duct adenocarcinoma after curative resection.
