Different glucose uptake and glycolytic mechanisms between hepatocellular carcinoma and intrahepatic mass-forming cholangiocarcinoma with increased (18)F-FDG uptake.

Abstract

HCCs have different glucose-regulating mechanisms from those of cholangiocarcinomas, even though both tumors showed increased (18)F-FDG uptake on PET scans. Further studies are required with regard to energy metabolism and (18)F-FDG uptake patterns in association with various oncogenic alterations regulating multiple steps of the glycolytic pathways.
