Dual-color silver-enhanced in situ hybridization (SISH) is a well-established method for determining the HER2 gene amplification status in invasive breast cancers with equivocal “2+” HER2 protein expression. Dual-color SISH applies 2 different probes on a single tissue slide: a probe for the HER2 gene and a centromere 17 (CEP17) probe. [...]
