RT Journal Article SR Electronic T1 Immunohistochemistry in the era of personalised medicine JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 58 OP 61 DO 10.1136/jclinpath-2012-201140 VO 66 IS 1 A1 Clare Margaret McCourt A1 David Boyle A1 Jacqueline James A1 Manuel Salto-Tellez YR 2013 UL http://jcp.bmj.com/content/66/1/58.abstract AB Background Immunohistochemistry (IHC) plays a central role in the histopathological classification of diseases, including cancer. More recently, the importance of immunohistochemical staining is increasing. IHC usage in diagnostics is invaluable; however, the genetic and therapeutic significance of biomarker immunostaining has become equally relevant. Content In this article, we would like to analyse the three distinct roles of IHC and review their individual impacts on modern diagnostic pathology: (1) diagnostic IHC; (2) genetic IHC and (3) therapeutic IHC. Summary Thus, we will characterise the different analytical processes that are required in the three approaches to IHC usage stated above, as well as the clinical significance and overall importance in patient management. This will allow us to hypothesise on the most appropriate laboratory environment and detection methods for the future.
