-Molecular genetics is playing an increasingly important role in patient care and pathology practice. Immunohistochemistry (IHC) is a valuable and practical tool employed by most pathologists on a regular basis.
-To highlight select examples of how IHC may be used in the realm of molecular diagnostics.
-Select sources on IHC relating to tumor subtyping, hereditary cancer screening, and treatment-response prediction are reviewed. These represent some of the areas in which IHC can be employed by anatomic pathologists to optimize patient care and further inform molecular testing.
-In the emerging era of personalized medicine, IHC continues to serve a valuable function, complementing and enhancing other molecular techniques.
