Objective To investigate the role of metronomic chemotherapy of S-1 on angiogenesis of hepatocellular carcinoma in animal model.Method S-1 was dissolved in a 0.5%(w/v)HPMC solution.(D).28 days after the treatment with 0.5%(w/v)HPMC solution,tumors in LCI-D20 mice were moved out.Tumor mass was measured and microvessel density(MVD)was used to evaluate angiogenesis in tumor.The cellular apoptosis was determined using flow cytometry.The expression of VEGE bFGF and TSP-1 was measured by RT-PCR.Results The mean tumor mass was 2.01,0.38,1.12,1.38,2.27 g in O,A,B,C,D group,respectively. The mean MVD was 39.57,19.90,5.93,17.10,29.53 in O,A,B,C,D respectively. The mean tumor cellular apoptosis rate was 4.08%,44.37%,31.73%,19.83%,and 8.25% in O,A,B,C,D respectively. The expression of VEGF and bFGF in O group was highest,and A was slightly low,and C and D raked the third place,and B was the lowst;The expression of TSP-1 in B was highest,and C and D were slightly low,and A raked the third place,and O was the Iowst. Conclusion Metronomic chemotherapy of S-1 destabilizes pre-existing tumor vasculature and inhibits ongoing angiogenesis.
