Detection of human epidermal growth factor receptor 2 gene in invasive breast cancer by fluorescence in situ hybridization and research of its association with tumor characteristics
Objective:To investigate the concordance of detecting human epidermal growth factor receptor 2(HER-2) status of patients with invasive breast cancer by fluorescence in situ hybridization(FISH) for gene amplification and immunohistochemistry(IHC) for protein overexpression and to evaluate the association between tumour characteristics and HER-2 gene amplification.Methods: The HER-2 status was evaluated in 41 invasive ductal breast carcinomas by both FISH and IHC.The associations between HER-2 gene amplificat...
