Abstract: Objective The aim of this study was to analyze the expression of hydrogen peroxide inducible clone-5 (Hic-5) and collagen type I alpha gene (COL1A1) in cancerous tissues and their predictive value for postoperative survival time of patients with hepatocellular carcinoma (HCC). Methods 97 patients with HCC underwent hepatectomy in our hospital during the period between September 2013 and July 2016, and all patients were followed-up for 36 months. The RT-PCR and immunohistochemistry were performed to detect Hic-5 and COL1A1 mRNA and their proteins in cancerous and non-cancerous tissues. Results The positive rate of Hic-5 protein in cancerous tissues was significantly higher than that in adjacent liver tissues (53.6% vs. 16.5, P<0.05), and the positive rate of Hic-5 mRNA was significantly higher than that in adjacent tissues (66.0% vs. 25.8%, P<0.05); the positive rate of COL1A1 protein in cancerous tissues was significantly higher than that in adjacent tissues (71.1% vs. 25.8%, P<0.05), and the positive rate of COL1A1 mRNA was significantly higher than that in adjacent tissues (78.4% vs. 30.9%, P<0.05); the positive rate of Hic-5 mRNA in patients with TNM stage I/II was significantly lower than that in with stage III/IV (56.4% vs. 78.6%, P<0.05), and the positive rate of COL1A1 mRNA was significantly lower than that in with stage III/IV (70.9% vs. 88.1%, P<0.05); the positive rate of Hic-5 in patients with portal vein thrombosis was significantly higher than that in without (82.5% vs. 54.4%, P<0.05), and the positive rate of COL1A1 mRNA was significantly higher than that in without (90.9% vs. 70.2%, P<0.05); the medium survival in 87 followed-up patients was 8.2 to 36.0 months[36.0(14.6,36.0) m; the 3-year cumulative survival in patients with positive Hic-5 expression was significantly shorter than that in with negative [26.3(16.1,36.0) m vs. 36.0(30.6,36.0) m, P<0.05], and the 3-year cumulative event-free survival was also significantly shorter than that in with negative [21.4(11.7,36.0) m vs. 36.0(24.2,36.0]m, P<0.05). Conclusion The positive Hic-5 expression in cancerous tissues in patients with HCC hint poor prognosis, which might be related to the advanced tumor stage and portal vein thrombosis.
