The FISH-positive frequency in IHC 0-1+ cases is 0.3% to 7.5% (Table 2). 5 With FISH testing, the results are quantitative instead of qualitative; tumors are interpreted as HER2 "negative" or "positive" by enumerating the HER2/neu gene copy number. 3 What does it mean if a patient is weakly positive by IHC? Patients whose tumors are weakly positive by IHC have weak or moderate intensity staining (see IHC 2+ slide Per determinare se il cancro al seno è HER2-positivo, il medico ordinerà test che vengono effettuati su un campione di tessuto. Due tipi di test sono approvati per HER2 diagnosi: immunoistochimica (IHC) e ibridazione in situ (ISH o FISH). Immunoistochimica (IHC) Test Concordance between FISH HER2 analysis and real‐time PCR from microdissected tissue was 78.1%, with 25 samples showing similar results in both FISH and real‐time PCR, including the two FISH positive samples. 2016-08-29 · We re-evaluated HER2 status of all samples for the current study by using FISH according to the new ASCO-CAP guidelines, which separates in situ hybridization (ISH) into five groups (Fig 2).

FISH-positive rates among IHC 2+ tumors vary (~13%-62%). 10,12,15,17,23,28,33 Esophagogastric tumors with a HER2/CEP17 ratio of 2 or greater are generally considered HER2-amplified. If the IHC result is 0 or 1+, it is controversial as to whether FISH should be ordered. The FISH-positive frequency in IHC 0-1+ cases is 0.3% to 7.5% (Table 2). 5 With FISH testing, the results are quantitative instead of qualitative; tumors are interpreted as HER2 "negative" or "positive" by enumerating the HER2/neu gene copy number.

Her2/CEN-17 ratio ≥2 . HER2 IQFISH pharmDx. TM • Pros – Less subjective than immunohistochemistry; an absolute quantitative score is generated – Her2 amplification by FISH correlates well with overexpression by IHC in breast cancer – Direct genetic evaluation of Immunohistochemistry (IHC) and triple FISH. IHC protocols for the ER, PgR, HER2 and Ki67 data used in this study have previously been described .Briefly, HER2 was scored in a 4-scale from 0–3, with intense membrane staining in >30% invasive tumor cells classified as positive (3+ staining) .Cut-offs were set for ER and PgR at 1% positive nuclei , and for Ki67 at 14% .

17 Feb 2010 Module 3: Interpretation of results of ICH and FISH AssaysProfessor Viale, from the European Institute of Oncology, interprets the results of ICH

2020-01-21 · The FISH test results will tell you that the cancer is either “positive” or “negative” (a result sometimes reported as “zero”) for HER2. Generally, the FISH test is not as widely available as another method of HER2 testing, called ImmunoHistoChemistry, or IHC. However, FISH is considered more accurate.

This image shows the appearance of the dual-colored FISH assay (DAKO HER2 FISH pharmDXTM, x1000 original magnification).

The special labels have chemicals added to them so they change color and glow in the dark when they attach to the HER2 proteins.
