Expression of the Androgen Receptor, pAkt, and pPTEN in Breast Cancer and Their Potential in Prognostication.

Although survival analyses showed no significant OS difference among the four groups ( P = .214), women with AR + /ER + tumors showed a trend for a better OS (mean OS = 5.0 ± 0.257 years) compared to the AR − /ER + (mean OS = 4.4 ± 0.573 years) subgroup.

However, despite displaying a positive trend of AR expression with survival, a significant association could not be ascribed in AR/ER subgroup analysis, and we would cautiously attribute this to the small sample size and low number of deaths.
