HER2 IQFISH pharmDx
In a fraction of patients (15-20%) with breast cancer, the HER2 gene is amplified as a part of the process of malignant transformation and tumor progression. HER2 gene amplification leads to overexpression of the HER2 protein on the surface of breast cancer cells.
HER2 gene amplification and receptor prevalence correlates with poor breast cancer prognosis, including relapse-free and overall survival.
