摘要
目的 检测SOX2蛋白、SOX7蛋白、β-连环蛋白(β-catenin)及细胞周期素(CyclinD1)蛋白在喉癌及癌旁正常上皮组织中的表达,并初步探讨其在喉癌发生中的临床意义。方法 将收集到的65例喉癌组织和其中40例对应癌旁正常上皮组织的石蜡切片进行免疫组化染色,检测SOX2、SOX7、β-catenin及CyclinD1蛋白的表达。结果 SOX2、β-catenin及CyclinD1蛋白在喉癌组织中的阳性表达率高于癌旁正常上皮组织(P<0.05),SOX7蛋白在喉癌组织中的阳性表达率低于癌旁正常上皮组织(P<0.05);喉癌组织中SOX2、SOX7、β-catenin及CyclinD1蛋白的阳性表达率与淋巴结转移及T分期相关(P<0.05),与吸烟、饮酒、年龄、性别、分化程度、临床分型等均无相关性(P>0.05);在喉癌组织中β-catenin和cyclinD1与SOX2蛋白的表达呈正相关(φ=0.732,P<0.001;φ=0.844,P<0.001),与SOX7蛋白的表达呈负相关(φ_(SOX7与β-catenin)=-0.213,P<0.001;φ_(SOX7与cyclinD1)=-0.455,P<0.001),且β-catenin与cyclinD1的表达呈正相关(φ=0.661,P<0.001),SOX2与SOX7的表达呈负相关(φ=-0.388,P=0.002)。结论 SOX2、β-catenin及CyclinD1蛋白在喉癌组织中高表达,SOX7蛋白在喉癌组织中低表达,推测SOX2、SOX7蛋白可能对喉癌的进展有一定影响。
