PURPOSE To examine the androgen receptor (AR) levels in breast cancer and to assess the impact of AR expression on patient outcomes. EXPERIMENTAL DESIGN Reverse-phase protein arrays were used to measure AR levels and a mass spectroscopy-based approach was used to detect PIK3CA mutations. Means and SDs were generated for AR levels. Linear regression models were used to determine if AR levels differed by tumor subtype and PIK3CA mutation status. Two-sample t tests were used to identify pair… CONTINUE READING
