Tissue microarray for routine clinical breast biomarker analysis. The British Columbia Cancer Agency 2008 experience.

ABSTRACT

Clinical use of tissue microarrays for immunohistochemical analysis of breast biomarkers, namely estrogen receptor, progesterone receptor, and HER2, was instituted in our laboratory in 2008. The method has proved reliable and cost-effective. We report the results of the initial year of testing with this method.
