EPCAM and hepatocellular carcinoma: Table 2 shows the EpCAM expression grades in the resected HCCs. No significant difference was recognized in each etiology according to the grade. Grade 0 was EpCAM negative, and Grades 1 to 3 were EpCAM positive. In 78% of the HBV patients (14/18), EpCAM expression was found in the resected HCC. Such expression was significantly higher than in those with other etiologies (HCV, 47%; NBNC, 41%) (Figure 2).
