Abstract

|
|
Background/Aims: Malignant cells exhibit increased glycolytic metabolism, and in many cases increased glucose transporter gene expression. We studied the expression of the glucose transporters in hepatocellular carcinoma(HCC) and intrahepatic cholangiocarcinoma(CC). also, examined the usefulness of Glut-1 glucose transporter in the discrimination of HCC from CC.
Methods and Results: 23 HCC, 15 CC and 8 normal liver tissues were investigated immunohistochemically with Glut-1 glucose transporter. Immunostaning was regarded as positive when more than 5% of cells were stained. Among 38 liver tumor cases, Glut-1 was stained in 15(40%). in 2(9%) of 23 HCC and in 13(87%) of 15 CC were positive.(P=0.001) In HCC, underlying cirrhosis, 18(78%) were negative.(P=0.04) Other prognostic factors: histologic type, lymph node metastasis, distant metastasis did not show any significant correlation.
Conclusion: Differential diagnosis between HCC and CC could be made by Glut-1 glucose transporter expression
