We investigated the correlation between GLUT-1 expression and signal transduction pathway related with pancreas cancer progression, and correlation between 18F-flurodeoxygluocose (FDG) uptake and these signal transduction pathway. We found that glucose transportwer-1 (GLUT-1) expression is associated with epidermal growth factor (EGFR), P70, mammalian target of rapamycin (mTOR), P-riboprotein, and riboproten on cell line. Immunohistochemical staining for these signal transfer factors was performed to 44 resected specimen of pancreas cancer. Maximum standardized uptake value (SUV max) was performed to evaluate the FDG uptake in pancreas cancer. SUV max of primary pancreas cancer correlated with GLUT-1, GLUT-3, P70 and EGFR expressions significantly. Our data suggest that FDG uptake mechanism of pancreas cancer is associated with GLUT-1, mTOR related signal transduction pathway and EGFR.
