Lung adenocarcinoma (LUAD) represents the major subtype of lung cancer, characterized by hypoxic-induced high glucose uptake and high glucose transporter type 1 (GLUT1) expression, making the measurement of 2-deoxy-2-[fluorine-18] fluoro-D-glucose (18 F-FDG) a promising diagnostic tool [2]. This evidence concerns the gene SLC2A1 and lung adenocarcinoma.
