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 کاملAnalysis of HER2 gene amplification using Differential PCR in breast cancer patients of Isfahan Province
Background: Amplification of HER2 is seen in 20-30% of breast cancer cases. Measurement of HER2 gene amplification appears to be of vital importance in planning the treatment schedule for patients with breast carcinoma. The aim of our study was to evaluate HER2 amplification status in malignant and benign breast tumors by differential PCR (dPCR). Materials and Methods: The genomic DNA was ex...
متن کاملDetermination of HER2 Gene Amplification using Chromogenic in Situ Hybridization (CISH) in Iraqi Patients with Breast Carcinoma
Background: Breast cancer is the most common malignancy among women worldwide.The human epidermal growth factor receptor (HER) is a transmembrane receptor in the epidermal growth factor (EGF) receptor family located at the long arm of human chromosome 17 (17q12). Diagnostic assays for HER2 in breast cancer provide important prognostic information and independently help guide management by ident...
متن کاملActivating HER2 mutations in HER2 gene amplification negative breast cancer.
UNLABELLED Data from 8 breast cancer genome-sequencing projects identified 25 patients with HER2 somatic mutations in cancers lacking HER2 gene amplification. To determine the phenotype of these mutations, we functionally characterized 13 HER2 mutations using in vitro kinase assays, protein structure analysis, cell culture, and xenograft experiments. Seven of these mutations are activating muta...
متن کاملEvaluation of MYC Gene Amplification in Prostate Cancer Using a Dual Color Chromogenic In Situ Hybridization (Dual CISH) Assay
Methods: MYC gene amplification by FISH and DAKO dual-color CISH Results: The study showed that the dual-color CISH assay can convert Texas red and fluorescein isothiocyanate (FITC) signals into chromogenic signals. The dual –color CISH assay was performed on 40 cases of prostate cancer. Amplification was identified in 12 of 40 (30%) tumors. No amplification was seen in 28 of 40 (70%) tumors. F...
