Correlations of Hormone Receptors (ER and PR), Her2/neu and p53 Expression in Breast Ductal Carcinoma Among Yemeni Women

Abstract

Aims: The purpose of this study was to determine if any relationship exists between Estrogen Receptor (ER),Progesterone Receptor (PR), Her2/neu, P53, and clinicopathological factors in female breast ductal carcinoma. Materials and Methods: One hundred and thirty seven (IDC=124, NIDC=13) ductal carcinomas were clinicopathologically and immunohistochemically analyzed and compared with 20 control cases of benign breast lesions in which assessment of Her-2/neu, ER, PR, and P53 has been performed, prospectively. Chi-square analysis was then used to correlate the above observations. Results: The overall immunoexpression of ER, PR, Her2/neu and P53 were 43.8%, 27%, 30.6% and 48.9%, respectively, of the 137 ductal carcinomas. A significant Positive association between ER or PR expression with lymph node involvement was found ( p= 0.004, p= 0.022 respectively), while p53 was found to be negatively associated with lymph nodes involvement (p= 0.03, 0.02, respectively). P53 also associated negatively to lymph node status (P=0.03) and positively with borderline tumor grade (p= 0.03). Conclusion: There are high rates of positive expression of ER, PR, Her2/neu and P53 among Yamani women with breast ductal carcinoma.
