Correlation of AR, EGFR, and HER2 Expression Levels in Prostate Cancer: Immunohistochemical Analysis and Chromogenic In Situ Hybridization

Abstract

This study was limited by small number of subjects, but it can still be inferred that the expression levels of the AR and EGFR proteins are inversely correlated in prostate cancer patients. The potential utility of EGFR and HER2 as prognostic factors or therapeutic targets warrants further study.
