The possible implication of SUVmax to distinguish between different histological types of lung cancer (squamous cell carcinoma or adenocarcinoma) has not yet been properly studied, though pulmonary squamous cell carcinoma displays a higher glucose transporter type 1 (GLUT-1) expression and F-FDG uptake than adenocarcinoma [11]. The gene discussed is SLC2A1; the disease is lung cancer.
