Interlaboratory comparison of HER-2 oncogene amplification as detected by chromogenic and fluorescence in situ hybridization.
PURPOSE Chromogenic in situ hybridization (CISH) is a new modification of the fluorescence in situ hybridization (FISH) technique for detection of oncogene amplification in archival tumor samples. In CISH, the oncogene probe is detected using a peroxidase reaction, allowing use of transmitted light microscopy. We compared detection of HER-2/neu amplification by CISH with a Food and Drug Adminis...
متن کاملHER-2/neu amplification detected by fluorescence in situ hybridization in fine needle aspirates from primary breast cancer.
BACKGROUND The HER-2/neu gene is amplified in 20-30% of human breast cancers and has been shown to have prognostic and predictive value for treatment with chemotherapy, hormone therapy and antibodies against the HER-2/neu domain (trastuzumab). The aim of our study was to evaluate the reliability of HER-2/neu determination by fluorescence in situ hybridization (FISH) on fine-needle aspirates (FN...
متن کاملHER-2/neu Oncogene Amplification by Chromogenic in situ Hybridization in 130 Breast Cancers Using Tissue Microarray and Clinical Follow-up Studies
Determining of HER-2/neu oncogene amplification has become clinically important for managing breast cancer. Fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC) are currently regarded as the standard methods. Chromogenic in situ hybridization (CISH) was investigated as a new modification with an accurate, sensitive technique. From 1998 to 2002, using CISH and IHC, the amplifi...
متن کاملAnatomic Pathology / HER-2/NEU FLUORESCENCE IN SITU HYBRIDIZATION
We correlated quantitative results obtained in 40 invasive breast cancer cases for HER-2 gene amplification by fluorescence in situ hybridization with protein expression by immunohistochemical studies with computer-assisted image analysis. Fluorescence in situ hybridization (FISH) results were quantified as the mean number of fluorescent signals per nucleus, and immunohistochemical slides were ...
متن کاملComparison of Chromogenic In Situ Hybridisation with Fluorescence In Situ Hybridisation and Immunohistochemistry for the Assessment of Her-2/neu Oncogene in Archival Material of Breast Carcinoma
The successful treatment of breast cancer is dependent upon a number of complex factors. Her-2/neu gene amplification is known to be one of the most common genetic alterations associated with breast cancer and its accurate determination has become necessary for the selection of patients for trastuzumab therapy. The aim of this study was to prove the consistency of chromogenic in situ hybridisat...
