Immunohistochemical microphotograph of primary HBV-HCC. Two identical slides of tissue were sectioned from each tumor sample and then prepared for IHC study as described. The left column probed for CK19 and right column probed for CDH17. The expression of CK19 seemed to coincide with that of CDH17 in these HBV-HCC. The vast majority of the CK19(+) tumor cells in these HCC also had strong CDH17 expression. The Spearman's correlation coefficient between CK19 and CDH17 was 0.414, P<0.001. Magnifications, ×100. HBV, hepatitis B virus; HCC, hepatocellular carcinoma; IHC, immunohistochemistry; CK19, cytokeratin 19; CDH17, cadherin 17.
