Objective To study the association of ERβ expression with the expression of hormonal receptor and prognostic biomarkers. Methods The expressions of ERβ
ERα
PR
Ki-67
HER-2/neu and p53 were detected in tissue samples from 109 breast cancer patients by immunohistochemistry on tissue microarray slides. The histologic grade
tumor size and lymph node metastasis status of 109 cases of breast cancer were recorded and served as comparison indexes. Results ERβ was expressed in benign epithelium and stroma cells
and breast cancer cells in 59% breast cancer tissues of different histologic types. ERβ was coexpressed with ERα in 45% breast cancer tissues. ERβ expression was found a statistically significant association with HER-2/neu (P0.05) and p53 (P0.05). No statistically significant association was seen between ERβ expression and histologic grade
tumor size and lymph node metastasis. Conclusion ERβ may be an important prognostic marker and therapeutic target in breast cancer.
