摘要: 目的:研究Livin和Caspase-3这两种蛋白在喉鳞癌组织中表达的意义及相关性分析。方法:免疫组化SP法检测Livin和Caspase-3蛋白在30例声带息肉和62例喉鳞癌中的表达情况。结果:Livin在喉鳞癌组织中表达显著高于声带息肉组织(P<0.01),而Caspase-3在声带息肉组织中的表达显著高于喉鳞癌组织(P<0.05);Livin和Caspase-3的表达与喉鳞癌的淋巴结转移、临床分期、组织分化程度均显著相关 (P<0.05),而与喉鳞癌的临床分型、吸烟史、年龄、性别无关(P>0.05);Livin与Caspase-3在喉癌组织中表达呈显著负相关(r=-0.448, P<0.05)。结论:Livin和Caspase-3关系密切,二者异常表达可能在喉鳞癌的发生发展及转移中发挥重要作用。

Abstract: PURPOSE: TO investigate the expression and their significance in laryngeal squamous cell carcinoma and the correlation between livin and Caspase-3. METHODS: Immunohistochemistry was used to detect the expression of livin and caspase-3 in 30 cases of polyp of vocal cord and 62 cases of laryngeal squamous cell carcinoma. RESULTS: The expression of livin laryngeal squamous cell carcinoma was significantly higher than that in polyp of vocal cord(P<0.01), however the expression of Caspase-3 was significantly higher in polyp of vocal cord than that in laryngeal squamous cell carcinoma (P<0.01). In laryngeal carcinoma,the expression of livin and Caspase-3 were associated with patients′Lymph node metastasis, Clinical stage and Differentiation (P<0.05), but independent of Clinical classification ,smoking history,patients′age and sex(P>0.05). A signifcantly negative relation was found between livin and Caspase-3 (P<0.05). CONCLUSION: Livin was positively related to Caspase-3,which might play an important role in the carcinogenesis and development of laryngeal carcinoma by synergic effect.
