抑癌基因 PTEN在结肠癌中的表达及其临床意义(2)
展有关。本实验研究结果表明 , 无淋巴结转移的 PTEN表达率明显高于有淋巴结转移的 PTEN的阳性表达率 , 两者间差异有统计学意义 ( P<0.05);随着浸润深度的加深 , 它的阳性
表达率逐渐降低 , 差异具有统计学意义 ( P<0.05), 与文献报道一致 , 肿瘤的发生是一件极其复杂的过程 , 人们对它与肿瘤发生及发展的关系仍然存在着许多争议和未知因素 , 转录前及转录后结肠癌发生、发展的调节机制尚需进一步探讨。
总之 , 本研究表明 , 结肠癌的发生、发展与 PTEN表达有关 , 它可为结肠癌的早期诊断、判断预后和指导治疗提供新的科学理论依据。
