Abstract
Background
18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is used in the differential diagnosis and staging of extrahepatic bile duct cancer (EBDC), but its prognostic value has not been fully elucidated. In this study, we investigated the prognostic value of FDG-PET in EBDC patients.
Methods
The study included 73 consecutive patients with EBDC, of whom 48 underwent surgical resection for EBDC. The effects of clinicopathological factors including the standardized uptake value (SUV) of the primary lesion and lymph node metastasis detected by FDG-PET (PET-N) on overall survival were evaluated.
Results
In all 73 patients, multivariate analysis showed that surgical resection (risk ratio 2.5, 95% confidence interval [CI] 1.17–5.35, P = 0.018) and the SUV (2.0, 1.07–3.91, P = 0.030) were independent predictors of survival. In the 48 patients who underwent surgical resection, multivariate analysis revealed that perineural invasion (risk ratio 3.2, 95% CI 1.28–7.93, P = 0.012), pathologic lymph node metastasis (3.4, 1.27–9.17, P = 0.015), and PET-N (4.0, 1.10–15.25, P = 0.036) were independent predictors of overall survival. In the 25 patients without surgical resection, the SUV showed a significant relationship with overall survival (P = 0.014).
Conclusion
Our data suggest that the SUV of the primary lesion is a useful prognostic factor in patients with EBDC, and the prognosis for patients with PET-N remains very poor despite surgical resection.
