Fluorodeoxyglucose (FDG) detected by positron emission tomography (PET) can be used to measure the glycolytic activity of tumor cells. Though the prognosis of patients with pancreatic adenocarcinoma is usually poor, a subset of patients with good prognoses may be discovered by determining the degree of FDG integration into tumors.


Fourteen patients with histologically proven pancreatic adenocarcinoma underwent 18F-FDG PET. The standardized uptake value (SUV) of 18F-FDG was calculated, and the patients were divided into high (> or = 3.0) and low (< 3.0) SUV groups.


The two groups were not significantly different in terms of age, tumor location and size, staging, and treatment. However, analysis by the Kaplan-Meier method revealed that the groups had different prognoses (log rank test, P < 0.05). The mean survival of patients with high SUV was 5 months, whereas that of patients with low SUV was 14 months. There were not strong correlations between the SUVs and tumor size (0.56), serum carbohydrate antigen 19-9 (0.39), or carcinoembryonic antigen (0.52).


SUV calculated with 18F-FDG can be utilized as a prognostic factor for patients with pancreatic adenocarcinoma.
