FISH also may be useful as a confirmatory reflex assay for breast carcinoma cases for which an equivocal score has been identified previously by immunohistochemistry. Interpretation HER2 gene amplification is reported as either amplified, not amplified, or equivocal. The HER2 gene copy number is specified, and the HER2/chromosome 17 ratio is

The reflex code for Immunohistochemistry is currently available. Subsequent to publication of the CAP/ASCO guidelines for HER-2/neu testing for breast cancer, clients have requested that Quest Diagnostics make this testing scenario available to meet the new guidelines set for implementation by December FISH Analysis – HER2. FISH Analysis for HER2 amplification for breast and gastric cancers.

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 It is suggested that interpretation of HER2 IHC staining should be based on membrane staining intensity, but not the completeness of the membrane staining in IMPC. It is suggested to determine the HER2 gene amplification status by using FISH when IHC staining shows moderate or strong intensity. The new VENTANA HER2 Dual ISH DNA Probe Cocktail assay is a fully automated, ready-to-use brightfield solution for determining HER2 gene status.

If the ratio is <2, HER2 gene ampliﬁ cation was not observed. The result is negative. If the ratio is ≥2, HER2 gene ampliﬁ cation was observed. The result is positive. A ratio at or near the cut-off (1.80 - 2.20) should be interpreted with caution. Leica HER2 FISH - Interpretation of Breast Specimens Cell Line Leica BondTM Oracle

47 GOLDFISH demonstrated good correlation with FISH and excellent interobserver interpretive reproducibility. 46,47 The GOLDFISH assay was configured for simplified, rapid manual interpretation without the need for enumeration of individual signals Multiple guidelines, including NCCN and CAP/ASCO 6,7, recommend the evaluation of human epidermal growth factor receptor 2 (HER2) protein expression by immunohistochemistry (IHC) assay for breast cancer specimens.Depending on the IHC result, a reflex test should be performed-using in situ hybridization (ISH)..
