Purpose.
To determine the relationship between fructose 1,6-bisphosphatase 1 (FBP1) expression and fluorine 18 (18F) fluorodeoxyglucose (FDG) uptake in patients with clear cell renal cell carcinoma (ccRCC), and to investigate how 18F-FDG uptake and FBP1 expression are related to tumor metabolism and tumor differentiation grade.
Materials and Methods.
A total of 54 patients with ccRCC underwent 18F-FDG combined positron emission tomography and computed tomography (PET/CT) before tumor resection.
The maximum standardized uptake value (SUVmax) for the primary tumor was calculated from the 18F-FDG uptake.
The relationship between SUVmax of primary tumor and the expression of FBP1, hexokinase 2 (HK2), and glucose transporter 1 (GLUT1) was analyzed via immunohistochemical analysis.
Results.
We identified an inverse relationship between FBP1 expression and SUVmax (P=0.031).
SUVmax was higher in patients with high-grade ccRCC (mean, 11.6 ± 5.0) than in those with low-grade ccRCC (mean, 3.8 ± 1.6, P<0.001).
FBP1 expression was significantly lower in patients with high-grade ccRCC (mean, 0.23 ± 0.1) than in those with low-grade ccRCC (mean, 0.57 ± 0.08; P=0.018).
FBP1 status could be predicted with an accuracy of 66.7% when a SUVmax cutoff value of 3.55 was used.
GLUT1 expression in ccRCC was positively correlated with 18F-FDG uptake and FBP1 status, whereas HK2 expression was not.
Conclusion.
SUVmax in patients with ccRCC is inversely associated with the expression of FBP1, and FBP1 may inhibit 18F-FDG uptake via regulating GLUT1.
SUVmax is higher in patients with high-grade ccRCC than in those with low-grade ccRCC, which could be the result of lower FBP1 expression in patients with high-grade ccRCC.
