摘要
目的探讨脊柱脊索瘤中E-cadherin和P120ctn的表达及其与肿瘤临床病理特征、肿瘤局部复发之间的关系。方法应用免疫组化方法检测40例脊柱脊索瘤标本和5例胎儿脊索组织标本中E-cadherin和P120ctn的表达情况。结果脊索瘤标本中E-cadherin和P120ctn的胞膜表达减低率分别为75.0%(30例)和67.5%(21例)。E-cad-herin的表达与肿瘤侵犯的椎节数目之间存在相关性(P<0.05),P120ctn的表达与肿瘤的病理学分级存在相关性(P<0.01)。二者均与肿瘤的平均复发时间之间存在相关性(P<0.05和P<0.01)。另外,E-cadherin和P120ctn的表达下调之间存在相关性(P<0.05)。COX回归模型分析证实P120ctn和肿瘤病理分级是脊柱脊索瘤术后局部复发的独立预测因素。结论脊柱脊索瘤中常发生E-cadherin和P120ctn的胞膜表达下调,且与脊柱脊索瘤的发生、发展有关。二者均是肿瘤侵袭和局部复发的有价值的生物学预测指标,P120ctn是脊柱脊索瘤局部复发的独立预测因素。
