Abstract
BACKGROUND: Treatment of hepatocellular carcinoma (HCC) with transcatheter arterial chemoembolization (TACE) is known to induce vascular endothelial growth factor (VEGF) expression. A recent study has shown that doxorubicin can repress hypoxic induction of VEGF expression in human cancer cells.
OBJECTIVE: To evaluate the combination effects of doxorubicin and TACE on the change of serum VEGF after TACE.
MATERIAL AND METHOD: Thirty patients with unresectable HCC were assigned into two groups, the experiment group (n = 15) received TACE with doxorubicin (25-50 mg) plus mitomycin C (5-10 mg), and the control group (n = 15) received TACE with mitomycin C (5-10 mg). Serum VEGF before and after TACE (24 hour) was measured by quantitative sandwich enzyme-linked immunosorbent assay.
RESULTS: Baseline serum VEGF was correlated with the size of tumor (r2 = 0.85; p = 0.03). In addition, serum VEGF was significantly elevated after TACE (p = 0.014). However; the change of serum VEGF after TACE is not statistically different in both groups (p = 0.72). At 2-years, the overall survival was 38% and 40% in the experiment and control group, respectively (p = 0.48).
CONCLUSION: The present study suggests that doxorubicin improves neither the level of serum VEGF nor the survival in HCC patients treated with TACE.
