摘要
目的研究iNOS、NQO1在不同分子分型乳腺癌中的差异及临床参数间相关性,为乳腺癌临床治疗进行探讨。方法回顾性收集接受改良根治术的乳腺癌患者100例,免疫组织化学检测癌组织iNOS和NQO1表达情况。计数资料采用χ~2检验或Fisher确切概率法,Spearman相关分析分析临床分子病理特征之间的相关性。结果 NQO1表达与乳腺癌TNM分期和淋巴结转移具有相关性(χ~2=6.603、4.938,P<0.05),HER-2过表达型中NQO1表达率高于luminal A型(χ~2=8.341,P<0.008)。iNOS表达与Ki-67表达、TNM分期及淋巴结转移情况相关(χ~2=5.243、8.157、5.929,P<0.05),luminal A型中iNOS表达率显著低于luminal B型(χ~2=7.990,P<0.008)。结论 NQO1和iNOS表达可能与乳腺癌的氧化应激过程有关,对促进乳腺癌进展有重要作用;不同分子分型乳腺癌之间的氧化应激水平可能不同,其具体分子机制需进一步设计实验研究。
Objective To investigate the difference of iNOS and NQO1 in breast cancer with different mo-lecular subtypes and the correlation between clinical parameters,and to explore the clinical treatment of breast can-cer. Methods The data on 100 patients with breast cancer who had undergone modified radical mastectomy was retrospectively reviewed.Expressions of iNOS and NQO1 were detected by immunohistochemistry.Numeration data was processed using χ2test or Fisher′s exact test.Spearman correlation was applied to analyze different clinical mo-lecular pathological features.Results NQO1 expression was correlated with TNM staging and lymph node metasta-sis（χ2=6.603,4.938,P〈0.05）,and the expression rate of NQO1 in overexpressing of HER-2 was higher than that in type luminal A（χ2=8.341,P 〈 0.008）. Expression of iNOS was related to expression of Ki-67,stage of TNM and lymph node metastasis（χ2=5.243,8.157,and 5.929,P〈0.05）,the expression rate of iNOS in lumi-nal A was significantly lower than that in type luminal B（χ2=7.990,P〈0.008）.Conclusions The expression of NQO1 and iNOS may be involved the process of oxidative stress associated with breast cancer,and it plays an im-portant role in the development of breast cancer. Different molecular level of oxidative stress between the types of breast cancer may be different,whose molecular mechanism needs to be further studied.
