FISH testing. FISH stands for fluorescence in situ hybridisation. It is a test that looks for gene changes in cells. Genes are made of DNA. They control everything the cell does, including when it grows and reproduces. FISH tests look for specific genes or parts of genes. Changes in genes can make the cancer cell: produce particular proteins
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.

FISH testing can tell your doctor whether you have this type of cancer, called HER2 -positive breast cancer, or a HER2-negative cancer with normal levels of the protein. Why Get a FISH Test At the
Accurate - optimized to precisely separate 1+ and 2+ cases gives you excellent FISH concordance, reducing avoidable FISH requests. To determine whether a tumor is positive for particular HER2 (ERBB2) mutations, which helps to guide treatment and predict the course of the disease (prognosis); sometimes to monitor treatment and for cancer recurrence When To Get Tested?

There was a 64% (156/244) concordance between FISH and DISH by anomaly (κ = 0.58, 95% confidence interval, 0.51-0.65; P < .0001) and an 83% (203/244) concordance by amplification status (κ = 0.58; 95% confidence interval, 0.47-0.69; P < .0001). 2020-06-06 2015-04-06 2020-09-21 2016-08-29 2018-06-19 HER2. amplified upon alternative testing, clinical studies to determine benefit of anti-HER2 therapy in these patients is urgently needed.

-For urothelial tumors, order H2UR / HER2 Amplification Associated with Urothelial Carcinoma, FISH, Jul 31, 2020 Most often, IHC (testing for the HER2 protein) is done first, followed by FISH ( testing for extra copies of the gene). IHC testing is less expensive Test Code. FP HER2 GA. Associations. Gastric and gastroesophageal junction ( GEJC) cancer;. Herceptin. Methodology. Fluorescence in situ Hybridization Mar 22, 2018 While HER2 testing is well established in directing appropriate treatment for breast cancer, a small percentage of cases show equivocal results We developed a quality assurance scheme by performing HER2 FISH on 724 patients randomly selected out of 1996 patients with breast cancer presenting at HER2 testing is usually done by immunohistochemical assessment of HER2 protein or by fluorescence in situ hybridization (FISH) analysis of the HER2 gene FISH.
A new HER2 test may (no longer should) be ordered on the excision specimen on the basis of some criteria (such as tumor grade 3). 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. The section currently offers prognostic IHC and FISH HER2 testing for breast and gastric cancers and diagnostic/prognostic FISH testing of lymphomas.
