Evaluation of dual immunohistochemistry and chromogenic in situ hybridization for HER2 on a single section.
The evaluation of HER2 status in invasive breast carcinoma can be performed by multiple methods. We assessed the feasibility of performing 2 of these, chromogenic in situ hybridization (CISH) and immunohistochemical staining, on single tissue sections of breast carcinoma. During assay development, sequential performance of immunohistochemical staining after CISH resulted in weaker HER2 expressi...

شبکه خود سازمانده پرکاربردترین شبکه عصبی برای انجام خوشه بندی و کوانتیزه نمودن برداری است. از زمان معرفی این شبکه تاکنون، از این روش در مسائل مختلف در حوزه های گوناگون استفاده و توسعه ها و بهبودهای متعددی برای آن ارائه شده است. شبکه خودسازمانده از تعدادی سلول برای تخمین تابع توزیع الگوهای ورودی در فضای چندبعدی استفاده می کند. احتمال وجود سلول مرده مشکلی اساسی در الگوریتم شبکه خودسازمانده به حسا...
Predicting Effects of Clinicopathological Variables on Her2 Gene Amplification by Chromogenic in situ Hybridization (CISH) in IHC Her2 (2+) Breast Cancer Patients; A Study from Iran
Background & Objective: The her2 amplification plays an important role in breast cancer management. Therefore, there is a need for using supplementary molecular methods in IHC equivocal cases. Present study has been conducted to determine the effects of clinicopathological variables on her2 gene amplification by chromogenic in situ hybridization (CISH) in IHC ...
متن کاملInterlaboratory 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 کاملMonosomy 3 by chromogenic in situ hybridization (CISH) in Iranian patients with uveal melanoma.
PURPOSE The aim of this study was to investigate the rate of monosomy 3 by CISH technique in Iranian patients with uveal melanoma (UM) and its correlation with clinical and histopathological features. METHOD Archival formalin fixed, paraffin-embedded material from 50 patients who had undergone enucleation for large uveal melanomas was obtained. Monosomy of chromosome 3 alteration by chromogen...
