摘要 目的探讨胶原和钙结合EGF域1(Ccbe1)在直肠癌中的表达及其与直肠癌淋巴管生成及预后的相关性。方法应用免疫组化法和实时荧光定量PCR方法检测Ccbe1在45例直肠癌和20例直肠息肉组织中的表达,LYVE-1免疫组化染色计数淋巴管密度(LVD),并结合临床病理特征和生存资料进行相关分析。结果直肠癌组织中Ccbe1蛋白和mRNA的表达较声带息肉组显著增加(P<0.01),Ccbe1阳性表达与LVD、Ducks临床分期和淋巴结转移密切相关(P<0.05)。Ccbe1阳性表达与生存率负相关(P<0.05)。结论直肠癌组织中Ccbe1过表达能够促进直肠癌淋巴管生成,检测Ccbe1表达可成为判断直肠癌预后新的生物学指标。
