摘要 目的:探讨VEGF-D及Flt-4蛋白在胰腺癌组织中的表达与胰腺癌淋巴结转移之间的关系。方法:选用63例根治性手术切除的胰腺癌组织分为有淋巴结转移组与无淋巴结转移组,另选取13例正常胰腺组织做对照。采用免疫组织化学方法(Envision法)检测VEGF-D及Flt-4蛋白在胰腺癌的表达,并进行统计学分析。结果:VEGF-D阳性表达产物主要见于癌细胞胞浆,而Flt-4阳性表达产物主要位于癌周组织的微血管和淋巴管内皮细胞胞浆。有淋巴结转移组癌组织中VEGF-D的表达率92%(23/25)高于无淋巴结转移组44.7%(17/38)(P<0.05);有淋巴结转移组中Flt-4蛋白阳性表达率92%(23/25)显著高于无淋巴结转移组中的47.4%(18/38)(P<0.05);VEGF-D、Flt-4的表达均与淋巴结转移呈明显正相关(P<0.05)。结论:胰腺癌中VEGF-D与Flt-4表达增高,具有促进胰腺癌的淋巴管增生,促进胰腺癌淋巴道转移的作用,可作为检测胰腺癌有无淋巴结转移的重要指标,选择性阻断VEGF-C或Flt-4的作用,对控制胰腺癌的淋巴道转移可能是一个有效的方法。
