The aim of this study is to investigate difference of antiangiogenesis ablility and interaction about bevacizumab and endostatin in vivo in lung cancer animal model.


First, we construct a Balb/c mice model with A549 lung adenocarcinoma cell. Then, we divide the mice into four groups randomly. Every group has six mice.


mice injected with normal saline every day aroud the tumor. Endostatin group: mice injected with endostatin (Recombinant endostatin) injection (3 mg/kg) every day Peritumoral. Bevacizumab group: mice injected with bevacizumab twice a week (biw/5 mg/kg) Peritumoral. Combing group: mice were injected with endostatin and bevacizumab (dose just like single drug group). After 16 days, we executed mice and got the tumor tissue for next analysis.


Based on this experiment, we found bevacizumab and endostatin expressed the ability for inhibiting tumor growth in vivo. Bevacizumab was more powerful (52.36% vs 38.68%). Combining bevacizumab with endostatin could get better results (64.15%) than single drug did. Bevacizumab played the role by inhibiting VEGF-A expression (60.8%). Endostatin took effect by inhibiting VEGF-A/C (14.6%, 30.3%). Combining group present better antitumor efficacy than any single drug group did. (79.7%, 44.2%).


Both bevacizumab and endostatin present the antiangiogenesis ability in vivo of lung cancer animal model. In our test, bevacizumab show better ability in inhibiting tumor growth than endostatin does. Additional, combing bevacizumab with endostatin reveal better potential to inhibit tumor growth than single drug does.
