摘要 目的:探讨PTEN在直肠癌中的表达及其病理特征的关系。方法:应用免疫组化MaxVison法检测60例直肠癌、30例腺瘤组织和正常直肠黏膜组织10例标本中PTEN的表达情况,并对其表达水平与直肠癌临床病理特征之间的关系进行相关性分析。结果:PTEN蛋白在直肠癌、直肠腺瘤与直肠正常黏膜组织的阳性率分别是43.3%(26/60)、93.3%(28/30)、100%(10/10),与正常直肠黏膜相比,直肠癌组织中PTEN表达明显降低,且随分化程度降低和临床分期增高呈递减趋势,有淋巴结转移和远处转移组明显低于无淋巴结转移和远处转移组。结论:PTEN在直肠癌组织中的表达下调,与其病理因素有关,PTEN检测可为直肠癌生物学行为判定和进一步的研究和治疗提供有效的病理学依据。
