Cancer Control 2001;8:415-418 Se hela listan på academic.oup.com 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. 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. VENTANA HER2 Dual ISH helps identify breast and gastric cancer patients eligible for treatment with HER2-targeted personalized therapies.

2018-07-02 · Answer: This example shows a dual-probe FISH slide where the tumor cells have an average of 5.2 red signals per cell for HER2 and an average of 4.3 green signals per cell for the centromere. The ratio of HER2 to centromere signals is 1.2, making the ratio “negative.” HER2 FISH S13-16145-1A 4.7:1 Hypodiploid Maximum HER2 Signal: 21.0 Positive/Amplified HER2/neu FISH results are best interpreted by analyzing the ratio with respect to the HER2/neu copy number. An H & E slide was reviewed and demonstrates lesional tissue. Analysis of HER2/neu gene amplification status was performed using an automated HER2 is a transmembranous protein closely related to EGFR and, like EGFR, has tyrosine kinase activity.

J Clin Oncol 34: 3518-3528, 2016 Link, Google Scholar: 10. A FISH test that detects amplification of the HER-2/neu gene in human breast cancer tissue specimens. Answer: Shown in this example is a dual-probe fluorescence in situ hybridization (FISH) slide where the tumor cells have an average of 3.2 red signals per cell indicating the average HER2 copy number and an average of 1.3 green signals per cell for the centromere, indicating copy number loss of chromosome 17. The ratio of HER2 to centromere

Negative HER2 A FISH test that detects amplification of the HER-2/neu gene in human breast cancer tissue specimens. 2020-01-21 · FISH testing is done on breast cancer tissue removed during biopsy to see if the cells have extra copies of the HER2 gene. The more copies of the HER2 gene that are present, the more HER2 receptors the cells have. These HER2 receptors receive signals that stimulate the growth of breast cancer cells. Appendix A: HER2 CISH test interpretation guide HER2 gene amplification Amplification High amplification: >10 dots, or large clusters, or a mixture of multiple dots and large clusters of the HER2 gene present per nucleus in >50% cancer cells. See Figures A, B, and C. A large cluster is an irregularly shaped group of signals, which FISH testing usually returns one of two results: positive or negative.

In situ hybridization (ISH or FISH) tests An in situ hybridization (ISH) test FISH testing measures the HER2/neugene copy number against a standard internal chromosomal control (CEP 17). Results are expressed as a ratio of the number of HER2 gene copies (orange) per number of chromosome 17 copies (green). 3 A normal ratio is less than 2 (FISH-). 3 A ratio greater than or equal to 2 HER2/neugene copies per chromosome 17 is gene- Leica HER2 FISH System for BONDTM - Interpretation Guide for Breast Cancer Tissue Count as 2 orange signals and 1 green signal Do not count. Nuclei with no signals or with signals of only 1 colour should not be scored. Only score those nuclei with 1 or more FISH signals of each colour Count as 1 orange signal and 2 green signals in situ hybridization (FISH) assay designed to quantitatively determine HER2 gene amplification in formalin-fixed, paraffin-embedded (FFPE) breast cancer tissue specimens and FFPE specimens from patients with adenocarcinoma of the stomach, including gastroesophageal junction.
