HER2 , som även kallas HER2 / neu och HER-2, är akronym för human epidermal HER2-positiv bröstcancer diagnostiseras av IHC- eller FISH-testet.

Ten cases were reported as equivocal even on FISH (ASCO/CAP 2013 guidelines). Polysomy 17 was noted in 55 cases (41%), of which 26 patients were≤50 years and 29 patients were >50 years of age. 2020-06-03 Remaining cases showed no amplification of HER2/neu gene, combined with aneuploidy of chromosome 17. All cases described by IHC as 0/1+ were also HER2-negative by FISH.

El HER2/neu, conocido también como ErbB2 y designado como cúmulo de diferenciación CD340 y p185, es un protooncogén localizado en el brazo grande del cromosoma 17, concretamente en la región 17q21.1. Su código es HGNC ERBB2. In this study, six patients were identified who were Her2/neu positive by FISH after a negative result by IHC, affecting their clinical course. Since only a total of 60 Her2/neu-positive patients were identified in the patient cohort, had only a reflex strategy been performed, 10% of the Her2/neu-positive patients would have been missed. (B) Shows FISH equivocal breast cancer were the average HER2 copy number is increased (> 4 but < 6) with a calculated HER2/CEP17 ratio of < 2. An equivocal FISH result requires additional testing (HER2 IHC, testing another block from the patients tumor, repeat FISH with an alternative chromosome 17 reference probe) to try and resolve the HER2 status for clinical decisions on adjuvant treatment.

Better testing. Better patient outcomes.

HER2 NEU =+3 and our doctor insist for FISH test, unfortunately they are very poor people we cant manage the chemotherapy cost further than FISH test cost . you may know the situation in Yemen right now , is there is a chance to do this FISH test free in Mumbai , or what can you advise us.

HER2-positiva tumörer identifieras, som randomiserades till behandling med HER-2/neu-amplifiering.

In mammoplasty samples, HER-2/neu interphase analysis showed 98.42% + 2.07 (range 95.00 - 100.00%) of the cells with orange to green ratio of less than 2, thus indicating no amplification, while 1.58% + 2.07 (range 0.00 - 5.00%) of the cells showed orange to green ratio of equal to or more than 2 thus indicating HER-2/neu amplification . HER2/neu is the human epidermal growth factor receptor 2, also called ERBB2 (Erb-B2 receptor tyrosine kinase 2) Perform HER2 FISH on the breast core Fluorescence in situ hybridization (FISH) is a test that “maps” the genetic material in a person’s cells. This test can be used to visualize specific genes or portions of genes.

Over-expression is observed in 20-25% of women with breast cancer. These patients are potential candidates for monoclonal therapy. HER2/neu amplification by FISH was noted in 72 (54%) cases, whereas it was non-amplified in 52 (39%) cases. Ten cases were reported as equivocal even on FISH (ASCO/CAP 2013 guidelines). Polysomy 17 was noted in 55 cases (41%), of which 26 patients were≤50 years and 29 patients were >50 years of age. FISH testing usually returns one of two results: positive or negative.
