摘要 目的:探讨肿瘤转移抑制基因nm23-H1和转移相关基因CD44V6在喉鳞状细胞癌(LSCC)的表达与颈淋巴结转移的关系。方法:采用免疫组织化学S-P法,检测82例LSCC,14例喉黏膜不典型增生,14例声带息肉,10例喉正常黏膜组织中的nm23-H1和CD44V6的表达情况。结果:①nm23-H1在LSCC组中阳性表达率为51.2%,明显低于声带息肉组和喉正常黏膜组(P<0.05),有颈部淋巴结转移组nm23-H1的阳性率(34.4%),明显低于无转移组(62.0%),(P<0.05),其蛋白表达与颈淋巴结转移呈负相关。②CD44V6在LSCC组的表达阳性率75.6%,明显高于3个对照组(均P<0.01),有颈淋巴结转移组CD44V6的阳性率(87.5)%,明显高于无转移组(68.0%),(P<0.05),其蛋白表达与颈淋巴结转移呈正相关。③LSCC中nm23-H1和CD44V6表达呈显著负相关(P<0.01)。结论:nm23-H1和CD44V6的表达与LSCC的颈淋巴结转移密切相关,nm23-H1和CD44V6的表达在颈淋巴结转移中起协同作用。两者的表达失衡可能与LSCC发生颈淋巴结转移密切相关。因此,检测nm23-H1和CD44V6可作为预测LSCC颈淋巴结转移潜能有价值的参考指标。
