A score of 3+ is considered HER2-positive. 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.

Specimen Requirements Pathology Report: For global HER2 FISH cases we require a copy of the HER2 IHC pathology report (if it is not available to us in NeoLINK™). The second part involved reassessment of HER2 status in breast cancers from women accrued to BCIRG-005 (ClinicalTrials.gov Identifier NCT00312208) whose cancers had HER2-to-CEP17 FISH ratios of less than 2.0 and an average of 4.0 to 5.99 HER2 genes per tumor cell (ISH-equivocal) or cancers with FISH ratios of less than 2.0 and average HER2 gene copies less than 4.0 per tumor cell (ISH-negative 2015-04-06 · HER2 assessment is routinely used to select patients with invasive breast cancer that might benefit from HER2-targeted therapy. The aim of this study was to validate a fully automated in situ hybridization (ISH) procedure that combines the automated Leica HER2 fluorescent ISH system for Bond with supervised automated analysis with the Visia imaging D-Sight digital imaging platform.

If the IHC result is 2+, the HER2 status of the tumor is not clear and is called "equivocal." This means that the HER2 status needs to be tested with FISH to clarify the result. Triple-negative breast tumors don’t have too much HER2 and also don’t have estrogen or progesterone receptors. They are HER2-, ER-, and PR-negative.

The FISH (fluorescence in situ hybridization) test checks the DNA of your cancer cells for extra copies of the HER2/neu gene. This gene makes proteins called HER2 (human epidermal growth factor

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. Purpose ASCO and the College of American Pathologists (ASCO-CAP) recently recommended further changes to the evaluation of human epidermal growth factor receptor 2 gene (HER2) amplification by fluorescent in situ hybridization (FISH). FISH is performed using PathVysion (Abbott Molecular, Inc) probes to the HER2 locus (17q11.2-q12) and the chromosome 17 centromere (D17Z1). Results are reported as a HER2:D17Z1 copy number ratio and interpreted according to ASCO/CAP guideline recommendations. analysis of breast carcinoma by interphase fluorescence in situ hybridization (FISH) assay of paraffin-embedded tumor sections. Performance and interpretation of the assay are done in accordance with ASCO/CAP guidelines for HER2 testing (reference below).

つまり、「FISH陰性でもHER2 score 0/1になる」ことは無いし、逆に「FISH陽性でもHER2 score 3+になる」事も無いのです。 ♯免疫染色とFISH法は全く異なる検査なので、それぞれは独立した所見です。最終的に「FISHが正解」と考えてもらって結構です。
