Objective To investigate the characteristic of the expression of facilitative glucose transporter 1 （Glut1） in bronchial aveolar carcinoma （BAC） and the relationship between expression of Glutl and fluorine-18 fluorodeoxyglucose （18F-FDG） uptake. Methods Twenty patients with BAC were imaged with 18F-FDG positron emission tomography （PET） before surgery. Maximum standard uptake value （SUVmax） and mean standard uptake value （SUVmean ） of tumor and standard uptake value of normal lung （SUVIung） were measured. The expression of Glutl was studied in paraffin sections by streptavidin peroxidase （SP） immunohistochemistry. Results All tumors of the patients could be detected by ^18F-FDG-PET. 18F-FDG uptake of tumor was higher than that of normal lung （SUV SUV and SUVlong were 3.09± 1.35, 2.37±1.03 and 0.39±0.09 respectively）. The expression of Glutl were positive in all tumors （73. 8%± 14. 8% of positive cell rate, 2. 8 ± 0. 9 grade of staining intensity）. Predominantly cytoplasm positive with weak staining intensity were observed in many tumors. Glutl negtive were observed in normal bronchial and lung parenchyma. Positive correlations were found among 18F-FDG uptake, Glut1 expression and tumor size （P〈0. 01）. Conclusion Glutl expression with peculiarity in BAC is correlate with 18F-FDG uptake.
