Prognostic prediction of PTEN and Her-2 expression in breast cancer / 中国病理生理杂志

ABSTRACT

AIM: To study the prognositic value of PTEN and Her-2 expression in primary breast cancer.METHODS: 81 breast cancer specimens with 15 years follow-up were obtained from 1989 to 2004.Immunohistochemical methods were used to detect the expression of PTEN and Her-2 in 81 paraffin-embedded specimens.The correlation between expression of PTEN and clinipathological factors was discussed with the Chi-square test.The survival rate analysis results were calculated with Kaplan-meier method.Long-rank test and Cox model by SPSS 10.0 software.RESULTS:(1) PTEN expression significantly affects 5-year and 10-year survival rate of breast cancer(P
