| 摘 要： | 目的研究抑癌基因PTEN在乳腺癌中的表达及其临床意义。方法采用免疫组化技术（S-P）检测72例乳腺癌中PTEN的表达情况。结果PTEN总的表达缺失率为62.5%（45/72）。PTEN表达缺失率与乳腺癌的组织学分级,TNM临床分期,腋窝淋巴结转移和生存时间有关（P〈0.05）,而与肿瘤的大小和ER、PR状况无关。结论检测乳腺癌PTEN在蛋白水平的表达缺失状况可能有助于对其预后的判断。 |

| Abstract: | Objective To study the expression and clinical significance of tumor suppressor gene PTEN in breast cancer. Methods Immunohistochemieal staining（S-P） was used to detect the expression of PTEN in 72 cases of breast cancer samples. Results Among these 72 samples,the rates of total expressing depletion of PTEN were 62.5% （45/72）. The rates of total expressing depletion of PTEN was significantly correlated with histological grade, TNM staging,axillary lymph nodes status and survival time （ P 〈 0.05 ）, but not with tumor size, estrogen and progesterone receptors. Conclusions The depletion of the expression of PTEN at protein level may contribute to prognostic criterion for breast cancer |
