摘要
In order to investigate the changes of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) expression in residual hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE), the expression levels of VEGF and bFGF expression in specimens surgically removed from 48 HCC patients were detected by immunohistochemical methods, and staining intensity of VEGF and bFGF was assessed by a computer-assisted image-analyzer Among the 48 patients, 25 underwent partial hepatectomy alone (single operating group), and 23 were subjected to second stage surgical resection after TACE (TACE group) The results showed that the average absorbance value (A) of VEGF was higher in TACE group than that in single operating group (0 152±0 021 vs 0 131±0 012, P< 0 01) The Average A of bFGF in TACE group was 0 127±0 023, higher than in single operating group (0 111±0 016, P <0 05) These results suggested that TACE of HCC can up-regulate the expression of VEGF and bFGF in HCC tissues possibly due to anoxia and ischemia
