Hepatocellular carcinoma (HCC) is a deadly and emerging disease leading to death in Asian countries. High hepatitis B virus (HBV) load and chronic hepatitis B (CHB) infection increase the risk of developing HCC. HBV is a DNA virus that can integrate DNA into host genome thereby increase the yield of transactivator protein HBxAg that may deregulate many pathways involving in metabolism of cells. Several monogenic and polygenic risk factors are also involved in HCC development. This review summarizes the mechanism involved in HCC development and discusses some promising therapies to make HCC curative.

Introduction:Hepatocellular carcinoma (HCC) is one of the most prevalent primary malignant tumors and accounts for about 90% of all primary liver cancers. Its distribution varies greatly according to geographic location and it is more common in middle and low- income countries than in developed ones especially in Eastern Asia and Sub Saharan Africa (70% of all new HCCs worldwide), with incidence rates of over 20 per 100,000 individuals.Explanation:The most important risk factors for HCC are Hepatitis B Virus (HBV) infection, Hepatitis C Virus (HCV) infection, excessive consumption of alcohol and exposition to aflatoxin B1. Its geographic variability and heterogeneity have been widely associated with the different distribution of HBV and HCV infections worldwide.Chronic HBV infection is one of the leading risk factors for HCC globally accounting for at least 50% cases of primary liver tumors worldwide. Generally, while HBV is the main causative agent in the high incidence HCC areas, HCV is the major etiological factor in low incidence HCC areas, like Western Europe and North America.Conclusion:HBV-induced HCC is a complex, stepwise process that includes integration of HBV DNA into host DNA at multiple or single sites. On the contrary, the cancerogenesis mechanism of HCV is not completely known and it still remains controversial as to whether HCV itself plays a direct role in the development of tumorigenic progression.

Abstract Backgrounds: The ratio of gamma-glutamyl transferase (GGT) to alanine aminotransferase (ALT) is a predictive biomarker for hepatitis and hepatocellular carcinoma (HCC). In this study, the relationship between GGT/ALT ratio and vascular invasion was explored in hepatitis B virus (HBV)-related HCC and tumor prognosis. Methods: Totally 558 patients were involved in this study. Univariate and multivariate logistic analysis were used to evaluate GGT/ALT as the risk factor of vascular invasion. Prognostic value of GGT/ALT was investigated by univariate and multivariate Cox analysis combined with Kaplan Meier curves. In order to reduce confounding bias, subgroup analysis and propensity score matching (PSM) were performed. Results: Patients were divided into high and low GGT/ALT groups with an optimal cut-off value of 2.95 in predicting vascular invasion. In univariate and multivariate logistic regression, high GGT/ALT group was listed as the independent risk factors for vascular invasion(P=0.03), the other risk factors included age (P=0.001), α-fetoprotein (AFP) (P=0.026), tumor size (P<0.001), tumor capsule (P=0.018), pathological differentiation (P<0.001) and Barcelona Clinic Liver Cancer (BCLC) classification (P<0.001). In survival analysis, high GGT/ALT ratio was associated with decreased overall survival (OS) (HR: 1.38; 95% CI: 1.03, 1.87; P<0.0001) and disease-free survival (DFS) rates (HR: 1.32; 95% CI: 1.03, 1.87; P<0.0001). In sensitivity analysis, comparable results were furtherly confirmed by subgroup analysis. In PSM analysis, GGT/ALT was still associated with vascular invasion independently (OR, 186; 95% CI, 1.23, 3.33). Conclusion: Preoperative GGT/ALT has good predictive value for vascular invasion, tumor severity and outcome in HBV-related HCC patients.
