摘要: 为进一步探讨浸润性乳腺癌中c-myc蛋白的表达及其临床意义,为乳腺癌患者的预后和治疗提供某种程度的指导,应用免疫组化SP法对116例原发浸润性乳腺癌标本进行c-myc蛋白表达测定。结果提示,c-myc蛋白在胞核和胞质中均有表达,核染色阳性者13例(11.2%),与乳腺癌患者预后明显相关;细胞质着色者108例(93.1%),中、强阳性表达病例与乳腺癌ER状况呈正相关性。提示c-myc蛋白核表达可作为判定乳腺癌预后的重要指标,对乳腺癌标本进行c-myc表达产物检测可能对治疗有一定的指导意义。

Abstract: To investigate the clinical significance of c-myc protein expression in breast cancer, the expression of c-myc protein in 116 breast cancer tissues was examined using immunohistochemical methods(SP). Nuclear expression of c-myc protein was detected in 11.2% of tumors, and it was related to prognosis. Cytoplasmic expression of c-myc protein was present in 93.1% of the carcinomas. Moderate to strong c-myc protein expression in cytoplasmic was associated with the positive status of ER. The result shows that nuclear expression of c-myc protein appears to be an important prognostic factor. To investigate the expression of c-myc protein in breast cancer may to some extent act as guidance to the therapy of breast carcinomas.
