1、摘要目的:研究p53基因codon72多态性与乳腺癌患者的年龄、病理分期、淋巴结转移、雌激素受体(ER)、孕激素受体(PR)、c—erbB一2、P53蛋白表达情况的相关性。方法:TaqMan探针方法检测277例乳腺癌患者血液标本的p53基因codon72多态性。免疫组化SP法检测匹配肿瘤纽织中ER、PR、c~erbB一2和P53蛋白的表达情况。SPSS16.0软件行统计学分析,p53基因多态性与病理学特征关系用x检验,非条件Logistic回归分析基因多态性与ER、PR、c—erbB一2、P53蛋白表达的相关性
2、,计算0R值及其95%-~3-4~区间(95%CI)。P0.05)。肿瘤组织P53蛋白表达与ER、PR、c—erbB一2蛋白表达密切相关(X2=13.492,P=0.000;X2=3.970,P=0.046;
3、~2=17.956,P=0.000)。结论:p53基因eodon72多态性与P53蛋白表达及病理学特征无相关性,P53蛋白表达与ER、PR、c—erbB一2蛋白表达关系密切。p53基因codon72基因型与患者发病年龄的关系有待扩大样本量进一步研究。关键词p53codon72乳腺癌免疫组化doi:10.3969/j.issn.1000—8I79.2010.09.005Studyonp53Codon72Polymorphismin277PatientswithBreastCancerZHOUXiaoying,ZH
