Core Tip

Core tip: Malignant cancers are preferential to metabolize glucose by glycolysis, even in the presence of oxygen, so-called Warburg effect. This elevated glucose metabolism is responsible for 18F-fluorodeoxyglucose (FDG) accumulation into cancer cells, which results in the positive signals in FDG-positron emission tomography scans. In spite of its clinical utility, the cellular and molecular mechanisms of 18F-FDG accumulation have not yet been elucidated. Here we review the current literature published with respect to the mechanisms of 18F-FDG accumulation into colorectal cancer tissues.
