摘要: 摘 要 目的:探讨抑癌基因FHIT和凋亡抑制蛋白Survivin在鼻腔鼻窦内翻性乳头状瘤中的表达与意义及其相关性。方法:采用免疫组织化学技术检测50例鼻腔鼻窦内翻性乳头状瘤和20例鼻腔鼻窦鳞癌以及20例正常鼻腔黏膜中FHIT蛋白和Survivin蛋白的表达,并结合临床分期,是否复发进行分析。 结果:(1)FHIT基因在鼻腔鼻窦内翻性乳头状瘤中组织中的阳性表达率为30%,与正常粘膜的差别有统计学意义(P<0.01),与鼻腔鼻窦鳞癌的差别无统计学意义(P>0.05),与鼻腔鼻窦内翻性乳头状瘤中临床分期,患者年龄无关。(2)Survivin蛋白在鼻腔鼻窦内翻性乳头状瘤中组织中的阳性表达率为80%,与正常粘膜的差别有统计学意义(P<0.01),与鼻腔鼻窦鳞癌的差别无统计学意义(P>0.05),并随鼻腔鼻窦内翻性乳头状瘤的临床分期递增,而且与患者年龄有关。(3)FHIT基因的失活和Survivin蛋白的诱导在鼻腔鼻窦内翻性乳头状瘤组织中的表达呈显著性关联(P<0.01)。结论:FHIT基因的失活和Survivin蛋白的诱导在鼻腔鼻窦内翻性乳头状瘤的发生发展中起重要作用,可能为鼻腔鼻窦内翻性乳头状瘤的诊疗提供新的靶点.

Abstract: Abstract Objective:To investigate the expression and significance of FHIT and it’s relationship with Survivin in sinonasal inverted papilloma (SNIP) . Method:Immunohistochemical method was used to determine the expression of FHITand Survivin in 50 cases of SNIP,20 cases of sinonasal squamous cell carcinoma (SCC) and 20 cases of normal sinonasal tissues,to analyse the result depending on clinical stages and recurrence . Results:(1)FHIT was expressed in 15 of 50 (30%) cases of SNIP,the diffences with normal sinonasal tissues have statistic significance(P <0.01) , the diffences with SCC have not statistic significance(P>0.05), and the expression is not relative to the clinical stages and the age. (2) Survivin was expressed in 40 of 50(80%) cases of SNIP, the diffences with normal sinonasal tissues have statistic significance(P<0.01) , he diffences with SCC have not statistic significance(P>0.05) ,and the expression are increasing with the clinical stages and the age. (3) The inactivation of FHIT and the activation of Survivin in SNIP are distinct correlation(P<0.01). Conclusion:The inactivation of FHIT and the activation of Survivin may play an important role in the pathway of progression of SNIP and SCC. They may be identified as a new therapeutic target .
