Abstract:
The expression of glucose transporter protein 1 (GLUT1) in malignant tumors is increased due to the higher metabolic needs of the proliferating cell populations. Aberrant GLUT1 expression is exhibited in a wide spectrum of epithelial malignancies and their precursors, which occur with low frequency and intensity; aberrant GLUT1 expression does not occur in normal epithelial cells. The expression of GLUT1 in tumors of the ampulla of Vater was evaluated on immunohistochemistry, and the relationships of GLUT1 expression to histological parameters and p53 expression were analyzed. Twenty‐one (58.3%) of 36 adenocarcinomas and three (17.6%) of 17 adenomas had GLUT1 immunoreactivity. None of the regenerating or normal epithelia had any immunoreactivity. No significant relationships were found between GLUT1 expression and histological parameters or p53 expression. It was found that histological subtypes originated from different epithelium were strongly related to different macroscopic types. In the ampulla of Vater, GLUT1 expression was associated with malignant change, and might be a useful marker of malignancy.
