HER2-CISH, Breast Cancer The Human Epidermal Growth Factor Receptor 2 (HER2) is a central biomarker in invasive breast cancer, and the HER2 status has both important prognostic implications, and is predictive for the patient’s response to HER2-targeted treatment.

This paper examined the concordance of human epidermal growth factor receptor 2 (HER2) status in core needle biopsy (CNB) specimens as determined by immunohistochemistry (IHC) or silver in situ hybridization (SISH), fluorescent in situ hybridization (FISH), or chromogenic in situ hybridization (CISH) with HER2 status of matched surgical resection specimens as determined by FISH as well as the

Seven cases with IHC score 0 were amplified at CISH. FISH analysis revealed an amplification in 5/42 cases (12%). The HER2 genetic testing was performed using 5 assays: HER2 CISH pharmDx Kit-SK109, HER2 FISH pharmDx Kit-K5331, HER2 IQ-FISH pharmDx-K5731 (Dako, Denmark), ZytoDot 2C SPEC HER2/CEN17 Probe Kit-C-3022-40 and SPEC HER2/CEN17 Dual Colour Probe Kit-Z-2020 (ZytoVision, Germany). CISH staining according to the “Dako Duo CISH” method for the “HER2 CISH pharmDxTM” probe kit Slides bearing TMA sections were deparaffinized and rehy-drated prior to incubation in “Pre-Treatment Solution” at 95–99 C inawaterbathfor10min.Subsequently,thesamples were subjected to enzymatic digestion in pepsin at 37 C in a hybridizer 2010-01-08 for HER2 overexpression or gene amplification.
