目的研究SU5416對大鼠胰腺癌微血管密度(MVD)的影響,判定其在腫瘤生長和轉(zhuǎn)移中的抑制作用。方法采用二甲基苯丙蒽直接置入大鼠胰腺,建立臨床類似胰腺癌的大鼠模型。將60只SD大鼠胰腺癌模型隨機分為4組,分別自腹腔注射生理鹽水(對照組)、5-氟尿嘧啶(5-FU組)、SU5416制劑 (SU5416組) 和5FU+SU5416聯(lián)合用藥 (聯(lián)合組),隔日1次,連續(xù)12周,于13周后處死大鼠,剖腹測量其腫瘤的MVD。 結(jié)果對照組、5-FU組、SU5416組和聯(lián)合組腫瘤MVD分別為(12.3±3.2)%、(11.4±3.8)%、(2.1±1.5)%和(1.8±1.1)%; 聯(lián)合組及SU5416組腫瘤MVD明顯低于5FU組和對照組(P<0.05),但5FU組與對照組比較差異無顯著性意義(P gt;0.05)。結(jié)論SU5416能有效降低大鼠胰腺癌模型中的腫瘤MVD,且與化療藥物聯(lián)合應用具有協(xié)同作用。
