Abstract
Background: Androgen receptor (AR) expression is frequently observed in breast cancer, but its association with estrogen receptor (ER) expression of breast cancer remains unclear. Methods: In this study, we analyzed the clinicopathological and molecular features associated AR loss in ER-positive and ER-negative breast cancer respectively, trying to elucidate the molecular correlation between AR and ER. Results: Our results showed that AR loss was associated with different clinicopathological characteristics in ER-positive and ER-negative breast cancer. Moreover, the expression of AR was correlated with different molecular features in ER-positive and ER-negative breast cancer.Conclusions: These results suggest that the role of AR in ER-positive breast cancer is distinctive from that in ER-negative breast cancer.
