Human epidermal growth factor receptor expression in colorectal cancer and its relationship with clinicopathological characteristics

ABSTRACT

Background: Some recent studies reported human epidermal growth factor receptor [HER-2/neu] as a marker that can be used in immunological studies of colorectal carcinoma for predicting the prognosis and the treatment. Therefore, we aimed to investigate the frequency of HER-2 expression in patients with colorectal cancer, and explore the relationship between clinicopathological prognostic factors and its expression based on immunohistochemical analysis:
