摘要 目的研究舌癌与p16基因启动子区域的Cp G岛甲基化的潜在关系,并了解p16基因甲基化与临床病理的关系。方法观察组舌癌标本及对照组正常舌组织标本所提取的DNA,经亚硫酸氢钠处理改变甲基化碱基,设计相应引物(p16-M、p16-U)Q-MSP扩增,检测样本中的甲基化比例。结果观察组甲基化阳性率为64.58%(31/48),对照组阳性率仅2.08%(1/48),差异有统计学意义(P<0.05);舌癌个体中pl6基因甲基化比例与病理分期、发生淋巴转移、组织学分化程度相关,与年龄、性别无关。结论 p16基因启动子Cp G岛甲基化现象与舌鳞癌的发生发展关系密切;癌症发展越晚期、肿瘤浸润更深、发生转移、更低分化者p16基因启动子Cp G岛甲基化的频率更高,但与患者年龄、性别等因素无关。
