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 2017-06-01 HER2 (Other) with Gastric scoring uses the 2016 CAP/ASCP/ASCO consensus guidelines for gastric/gastroesophageal adenocarcinoma for HER2 evaluation. 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 case was reflexed to FISH [fluorescence ISH] due to “histopathologic discordance” and reported as equivocal. The HER2/D17Z1 (chromosome 17 centromere) FISH ratio was 1.4 (negative) “to be interpreted with caution” due to the average copy number signals per cell of HER2 … 2019-03-01 HER2 amplification is associated with accelerated disease progression and poor prognosis in malignancies afflicting women, e.g., in breast cancer and endometrial carcinoma 3-5.

Amplification of the HER2/neu gene has been identified in 15–30% of breast cancer and endometrial cancer 6-8. 2016-07-27 2018-07-12 FISH is performed using PathVysion (Abbott Molecular, Inc) probes to the HER2 locus (17q11.2-q12) and the chromosome 17 centromere (D17Z1).

Equivocal HER2 amplification: FISH ratio of 1.8-2.2 or HER2 gene copy of 4.0-6.0. Negative HER2 amplification: FISH ratio is less than 1.8 or HER2 gene copy of less than 4.0. Read More

Shaded fields must be completed LEGIBLY (patient demographics may be addressographed instead). Please send the block of tissue to be tested and a HER2 Neu immunostained slide (or 3 unstained slides on “PLUS” slides, a H&E stained slide and a HER2 Neu immunostained slide). HER2/neu status in breast cancer specimens: Comparison of immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) methods. Int. J. Morphol., 33(2):737-742, 2015.

Breast tissue results of FISH group 2, 3, or 4 will be reflexed to ERBB2 (HER2/neu) (HercepTest) with Interpretation by Immunohistochemistry, Tissue (ARUP test code 0049174). Additional charges apply.

Fisktest för bröstcancer. Bestämning av HER2-tumörstatus med FISH Det skapas av en speciell gen som kallas HER-2 / neu-genen. HER-2 är en receptor för Vid 0 finns ingen amplifiering (ackumulering) av HER2-genen. Med indikatorerna 1+ och 2+ rekommenderas en FISH-studie för att klargöra 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. 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 FISH and IHC tests To determine if your breast cancer is HER2-positive, your doctor will order testing that’s conducted on a tissue sample.

A FISH test that detects amplification of the HER-2/neu gene in human breast cancer tissue specimens. HER2-positive and HER2-negative refer to two different types of breast cancer. In recent years, there have been significant developments in the treatment of HER2-positive breast cancer. Learn more HER2 overexpression (by IHC or FISH) identifies patients who might derive benefit from HER2 targeted therapy Trastuzumab based chemotherapy in patients with HER2 overexpression results in prolongation in median survival, progression free survival, overall response rate, clinical benefit rate and duration of response (Lancet 2010;376:687) 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 HER2/neu遺伝子とは HER2/neu遺伝子はがん遺伝子のひとつであり、1986年にその配列が決定されました(1)。この遺伝子のコードする産物（HER2/neu タンパク）はチロシンキナーゼ活性をもつ分子量185kDaの細胞膜を貫通する受容体型タンパクであり、乳癌や卵巣がん・胃癌において高頻度に増幅または Wann ist eine HER-2/neu-FISH-Analyse nötig ?

H&ES slides were used for diagnosis and for selecting paraffin blocks for HER2/neu IHC and FISH analyses. 2004-06-01 ER/PR/HER2 with Reflex to HER2 FISH, Paraffin Block - Estrogen and progesterone receptor assays are routinely performed on breast carcinomas to assess responsiveness to endocrine therapy and prognosis. HER-2 is associated with cellular proliferation activity. Over-expression is observed in 20-25% of women with breast cancer.
