The (LNT) Lung neuroendocrine tumor represents approximately 20% of all lung cancers. The classification of LNT relies upon morphology. Recently, in the World Health Organization (WHO) classification, Ki-67 rate has been proposed for classi fication. It is, however, known that Ki-67 count has a poor interlaboratory reproducibly. For that reason, our team has looked for a new biomarker.~GLUT1 protein a facilitative glucose transporter protein which has ubiquitous expression in mammalian. GLUT1 is overexpressed in many human cancers. But, no study has evaluated the GLUT1 staining as an aid diagnosis in LNT.
