Objective.—In this current study, we implemented the guidelines and addressed our institution's preanalytic, analytic, postanalytic variables relating to HER2 improve clinical outcomes. Design.—We evaluated core biopsies performed on breast lesions 2006 through 2007. Prognostic/predictive markers obtained by IHC were correlated with fluorescence in situ hybridization (FISH). Preanalytic biopsy variation studied collecting data number that needed repeat because inconclusive FISH results. Results.—In year preceding implementation guidelines, concordance was 98%. In an additional 10.8% cases, results inconclusive. When material became available re...
