Abstract:

目的检测喉癌组织中Dickkopf-1的表达,分析其表达与喉癌临床病理因素之间的关系及探讨与喉癌发生、发展的关系及临床的潜在价值。方法采用免疫组化SP法检测56例喉癌组织和20例喉部正常黏膜组织中的Dickkopf-1的表达情况。结果Dickkopf-1蛋白在喉癌组织中的阳性表达率为44.64%,明显低于喉部正常黏膜组织的90.00%。Dickkopf-1表达在有淋巴结转移组为15.79%,明显低于无淋巴结转移组的64.86%。在临床Ⅲ~Ⅳ期组阳性表达率为27.03%,明显低于临床Ⅰ~Ⅱ期组的84.21%,低分化组为15.38%低于高分化的63.16%及中分化组的58.33%,差异均有统计学意义(P均P>0.05)。结论Dickkopf-1在喉癌组织中的阳性表达率明显低于喉部正常黏膜组织,提示Dickkopf-1表达可能与淋巴结转移、临床分期和病理分级有关。
