[摘要] 目的 探讨组织型激肽释放酶6(Klk6)、Her-2蛋白及Ki-67在子宫内膜癌中表达的意义。 方法 应用免疫組化检测正常增生期内膜、单纯性增生性内膜、复杂性不典型增生性内膜各19例和子宫内膜样腺癌38例中Klk6、Her-2蛋白、Ki-67的表达情况。利用统计学软件SPSS 17.0和Graphpad Prism 5进行统计学分析检测并探讨其意义。 结果 Klk6、Her-2蛋白、Ki-67在癌组织中表达高于其他病变(P<0.05),Klk6在不同肿瘤临床分期中表达有明显统计学差异(P<0.05);而Klk6、Her-2蛋白在子宫内膜癌分级及淋巴结有无转移表达无统计学差异(P>0.05)。 结论 Klk6、Her-2蛋白、Ki-67在子宫内膜癌中的表达与肿瘤发生有一定的相关性,特别是Klk6与子宫内膜癌分期相关,对临床诊断、治疗及评估预后具有一定的价值。

[Abstract] Objective To investigate the significance of expression of tissue-specific kallikrein 6 (Klk6), Her-2 protein and Ki-67 in endometrial carcinoma. Methods Immunohistochemistry was used to detect the expression of Klk6, Her-2 protein and Ki-67 in normal proliferative endometrium(n=19), simple proliferative endometrium(n=19), complex atypical hyperplastic endometrium (n=19) and endometrioid adenocarcinoma(n=38). Statistical software SPSS 17.0 and Graphpad Prism 5 were used to detect and explore its significance. Results The expression of Klk6, Her-2 protein and Ki-67 in cancer tissues was higher than that in other lesions(P<0.05). There was statistically significant difference in the Klk6 expression among different clinical stages(P<0.05). There was no significant difference in the expression of Klk6 and Her-2 protein among different grades of endometrial carcinoma or in endometrial carcinoma with or without lymph node metastasis(P>0.05). Conclusion The expression of Klk6, Her-2 protein and Ki-67 has some correlation with the occurrence of endometrial carcinoma, and has certain value for clinical diagnosis, treatment and prognosis evaluation, of which especially Klk6 is associated with staging of endometrial cancer.

组织激肽释放酶基因家族(kallikreins,Klks)是广泛存在于人体各组织中编码丝氨酸蛋白酶的一组同源基因。现已发现Klks基因家族所编码的组织激肽释放酶共15种[1,2],参与细胞到组织发生、发展的许多正常生理过程,如牙齿及神经、生殖系统的发育[3-5]等,此外,还与肿瘤的转移有关。大量研究表明Klks在许多肿瘤及非肿瘤疾病中有一定的表达差异,从而应用于临床诊断中,如Klk3即前列腺特异性抗原(PSA)已被广泛应用于前列腺腺癌的筛查,是诊断、预后、监测最重要的标记物之一[5,6];也有研究表明Klk6在卵巢癌的发生发展、浸润转移等方面有一定作用[7],但在子宫内膜相关病变中研究较少。Her-2基因是某些肿瘤分子靶向治疗检测基因之一,现临床对Her-2基因阳性的肿瘤分子靶向治疗具有良好的效果,如胃癌、乳腺癌等[8-11]。Ki-67是细胞增殖指数,对肿瘤预后的评估有一定作用。本实验通过检测正常增生期、良性增生及子宫内膜癌中的Klk6、Her-2蛋白的表达及Ki-67增殖指数,分析与临床病理参数的相关性,以探讨在子宫内膜癌发生发展中的作用,为子宫内膜癌的诊断、治疗、预后提供参考数据。
