Abstract:
[Abstract] Objective To determine the expression of carboxylic acid-terminal truncated hepatitis B virus X protein (Ct-HBx) in hepatocellular carcinoma (HCC) tissues and corresponding adjacent non-tumor tissues, and to explore its effect on postoperative prognosis of HCC patients. Methods Immunohistochemistry was performed to measure the expression levels of Ct-HBx in 462 HCC tissues, 263 matched adjacent tissues and 25 matched tumor thrombus tissues. The relationships between Ct-HBx expression and clinicopathological data and postoperative prognosis of HCC patients was analyzed. Results The positive rates of Ct-HBx in 263 HCC and paired adjacent tissues were 43.73% (115/263) and 11.79% (31/263), respectively. Multivariate Cox regression analysis showed that age, portal vein cancer thrombus (PVTT), preoperative aspartate aminotransferase (AST), preoperative α-fetoprotein (AFP), small daughter nodule, preoperative Barcelona Clinic Liver Cancer (BCLC) stage and postoperative antiviral treatment were independent risk factors of postoperative recurrence of HCC patients (all P0.05), and the PVTT, preoperative AFP, tumor encapsulation, preoperative BCLC stage and Ct-HBx.
