Since only a total of 60 Her2/neu-positive patients were identified in the patient cohort, had only a reflex strategy been performed, 10% of the Her2/neu-positive patients would have been missed. (B) Shows FISH equivocal breast cancer were the average HER2 copy number is increased (> 4 but < 6) with a calculated HER2/CEP17 ratio of < 2. An equivocal FISH result requires additional testing (HER2 IHC, testing another block from the patients tumor, repeat FISH with an alternative chromosome 17 reference probe) to try and resolve the HER2 status for clinical decisions on adjuvant treatment.
