1、重庆医科大学硕士学位论文肝内胆管癌组织中PlGF的表达与MVD的关系姓名:傅翔申请学位级别:硕士专业:外科学指导教师:王济明201205肝内胆管癌组织中PIGF的表达与MVD的关系摘要背景肝内胆管癌(intrahepaticcholangiocarcinoma,Icc)是原发性肝癌中第二常见的病理类型,近年来它的发病率和死亡率在全球范围内均呈上升趋势。因为肝内胆管癌有较强的侵袭性,大多数病人在诊断时病情都已经发生了进展。在根治性切除后5年生存率也只有22—36%。部分研究揭示了肝内胆管癌内若干病理和生
2、理性的预测因子,但它具有较强侵袭性的准确原因仍然还不清楚。目的研究肝内胆管癌组织中PlGF的表达的意义及其与微血管密度(microvesseldens时,㈣)之间的关系。方法通过免疫组织化学的方法检测50例肝内胆管癌细胞及8例非肿瘤死亡后立即尸解的正常肝组织胆管上皮细胞P1GF的表达,并通过CD34测定肝内胆管癌组织微血管密度和正常肝组织门管区的微血管密度。结果肝内胆管癌组织PlGF阳性表达率、强阳性表达率分别为54%、28‰正常肝组织胆管上皮细胞P1GF阳性表达率、强阳性表达率分别为25%、0%,肝
