EGFR and hepatocellular carcinoma: First, our immunohistochemistry study showed that the rate of EGFR positive expression was 34.2 % in HCC tissues, 27.9 % in para-cancerous tissues, and only 13.0% in normal liver tissues, indicating higher EGFR expression in HCC tissues than in para-cancerous and normal liver tissues (Figure 3A, 3B).
