AIM: To investigate the role of vascular endothelial growth factor (VEGF) and CD44v6 in the recurrence and metastasis of hepatocellular carcinoma (HCC) after transcatheter hepatic arterial chemoembolization (TACE).
METHODS: The expression of CD44v6 and VEGF in 29 HCC samples obtained from the patients underwent secondary hepatectomy after TACE was examined by immunohistochemical staining and morphometric analysis. HCC samples (n = 30) obtained from the patients without TACE were used as the control group.
RESULTS: The value of VEGF absorbance in the TACE group was 0.149 ± 0.021, significantly higher than that in the controls (0.134 ± 0.018, P < 0.05). The positive rate of CD44v6 expression was 82.8% and 66.7% in the TACE group and control group, respectively, without significant difference between them (P > 0.05). The numbers of CD44v6 positive cells were also not markedly different between the two groups (112.4 ± 22.3 vs 102.4 ± 21.2, P > 0.05).
CONCLUSION: VEGF may take part in the recurrence and metastasis of HCC after TACE, while CD44v6 may not.
