Fas、FasL蛋白与乳腺癌相关性的临床研究

摘要

Objective:To investigate the clinical significance of the expression of Fas and FasL in breast cancer tissue and their relationship with the prognosis of breast cancer.Methods:Immunohistochemical technique was used to detect protein expression proportion and the level of Fas and FasL in 60 cases of breast cancer and 10 cases of benign breast tumor tissues.the experimental data were analyzed using semi-quantitative count and SPSS22.Results:The positive rate of Fas,FasL in breast cancer and benign breast tumor tissues were 78.33％ (47/60),80％ (8/10) and 95％ (57/60),70％(7/10),the positive rate of Fas protein in breast cancer tissues was higher than that of benign breast tumors,the positive rate of FasL protein in breast cancer was lower than that in benign breast tumor tissue.Fas、FasL protein expression were no significantly correlated with that of breast cancer staging,age,molecular typing,HER-2 and axillary lymph node status.but The strong expression of Fas,FasL protein were significantly correlated with that of the axillary lymph node status and the expression of ki-67.Conclusion:The strong expression of Fas,FasL protein may be associated with breast cancer metastasis and progress,and they could be as indicators of the evaluation of prognosis of breast cancer.%目的:探讨Fas、FasL在乳腺癌组织中表达的临床意义及其与乳腺癌预后的关系.方法:应用免疫组织化学方法检测Fas、FasL蛋白在60例乳腺癌及10例乳腺良性肿瘤组织中的表达情况.结果:Fas、FasL在乳腺癌及乳腺良性肿瘤组织中的阳性率分别为78.33％ (47/60)、80％ (8/1 0)及95％ (57/60)、70％ (7/1 0),Fas蛋白在乳腺癌组织中的阳性率低于乳腺良性肿瘤,FasL蛋白在乳腺癌组织中的阳性率高于乳腺良性肿瘤组织.Fas、FasL蛋白的表达与乳腺癌患者的年龄、分期、分子分型、HER-2状况及腋窝淋巴结转移情况无关,但Fas、FasL蛋白的强阳性率与乳腺癌腋窝淋巴结转移及Ki-67的表达明显相关.结论:Fas、FasL蛋白强阳性与乳腺癌的转移、进展相关,可能作为乳腺癌预后的一个评估指标.
