Purpose: To evaluate whether tumor androgen receptor (AR) expression was prognostic
and/or predictive for endocrine treatment alone or in combination with estrogen receptor …

Purpose The increase in clinical trials with androgen receptor (AR)-targeting drugs
emphasizes the need of clarifying the role of AR expression in different breast cancer …

Background Androgen receptor (AR) is widely expressed in breast cancer (BC) but its role in
estrogen receptor (ER)-positive tumors is still controversial. The AR/ER ratio has been …

Purpose: Androgen receptor (AR) is commonly expressed in breast cancers. However, the
association between tumor AR status and breast cancer survival is uncertain. Hence, we …

Purpose The androgen receptor (AR) is intensively discussed as a prognostic and/or
predictive marker in breast cancer patients. Methods We evaluated the value of AR mRNA …

The significance of androgen receptor (AR) in breast cancer (BC) management is not fully
defined, and it is still ambiguous how the level of AR expression influences oestrogen …

Background The androgen receptor (AR) is an emerging prognostic marker and therapeutic
target in breast cancer. AR is expressed in 60–80% of breast cancers, with higher …

Background The objective of the study was to evaluate the implications of androgen receptor
(AR) in breast cancers. Patients and methods We investigated immunohistochemical AR …

Differential prognostic roles of Androgen Receptor (AR) have been proposed in breast
cancer (BC) depending on tumour oestrogen receptor (ER) status. This study aimed to …

The aim was to investigate the implications of androgen receptor (AR) expression levels on
outcomes for estrogen receptor (ER)-positive tumors. Immunohistochemically AR levels …
