摘要: 目的检测乳腺浸润性导管癌组织中Ki-67和p53的表达, 并探讨其表达在乳腺浸润性导管癌中的临床意义。方法 免疫组化S-P法检测乳腺浸润性导管癌组织及乳腺良性病变组织中Ki-67和p53的表达, 统计学分析Ki-67和p53表达与乳腺浸润性导管癌患者临床病理特征及预后的关系。结果 Ki-67和p53蛋白在乳腺浸润性导管癌中均呈高表达, 42例组织中Ki-67阳性表达率78.6%, p53为38.1%, 乳腺良性病变中Ki-67无表达, 2例p53阳性表达, 两组存在显著性差异;Ki-67与p53的表达率随浸润性导管癌TNM分期的增高而上升, 另外Ki-67表达与浸润性导管癌的大小密切相关。结论 Ki-67和p53蛋白与浸润性导管癌TNM分期密切相关, 对其进行联合检测可有助于浸润性导管癌的预后判断。

Abstract: Objective To investigate the expression and clinical significance of Ki-67 and p53 in breast invasive ductal carcinoma(IDC).Methods Immunohisto chemical SP method was applied to detect the expression of Ki-67 and p53 protein in 42 cases with IDC and 18 cases with benign breast lesions, statistical analysis was performed to correlate the expression of Ki-67 and p53 with their clinical parameters.Results The positive expression percentage of Ki-67 and p53 was significantly higher in IDC cases than that in benign lesions cases(78.6% VS 0, 38.1 VS 5.6%).There was significant association between Ki-67, p53 expression and TNM staging, Ki-67 and p53 increasing correlated with higher TNM staging.There was another significant association between Ki-67 expression and tumor size.Conclusion The findings suggest that the positive expression of Ki-67 and p53in IDC make a closed correlation with TNM staging, Co-determining the expression of Ki-67 and p53in IDC case may play an important role in prediction of the IDC prognosis.
