Working with our dedicated and highly trained Surgical Pathology Team at UR Medicine Labs means that you will receive quicker turnaround for … The FISH test uses fluorescent pieces of DNA that stick to the HER2 gene in cells, which can then be counted under a microscope. UpToDate. Breastcancer.org: "HER2 Status," "How Triple-Negative 2016-08-03 The indiscriminate use of alternative control probes to calculate HER2 FISH ratios in HER2-equivocal breast cancers may lead to false-positive interpretations of HER2 status resulting from unrecognized heterozygous deletions in 1 or more of these alternative control genomic sites and incorrect HER2 … Her2 Neu Positive By Fish.

Interpretation HER2 gene amplification is reported as either amplified, not amplified, or equivocal.

FISH and HER2/ neu equivocal immunohistochemistry in breast carcinoma IHC is a good screening tool for negative and positive results. Any patient targeted for trastuzumab therapy should undergo confirmation of HER2/neu equivocal status by FISH analysis.

If the IHC test results are borderline, it’s likely that a FISH test will be done on a sample of the cancer tissue to determine if the cancer is HER2-positive. FISH test (F luorescence I n S itu H ybridization): The FISH test uses special labels that attach to the HER2 proteins.

(C) Should be considered HER2 positive by IHC. Tumors with this staining pattern show a good concordance with HER2 gene amplification by FISH in the majority of cases and will be the most likely to benefit from HER2 targeted therapy. A score of 3+ is considered HER2-positive.
