Chronic hepatitis B virus (HBV) infection leads to a risk of developing cirrhosis and hepatocellular carcinoma. In France, where the prevalence of HBV is low, mother-to-child transmission is the cause of chronic infection in more than one-third of cases. After exposure, the risk of chronic infection is the highest for newborns (90 %). The World Health Organization implemented a global immunization program in 1991, applied in France in 1994. A significant number of children are infected each year, however, and failure of postexposure prophylaxis is reported in 4-10 % of newborns...

AIMS: Glypican-3(GPC3) expression is correlated with poor prognosis and progression in hepatocellular carcinoma (HCC). HCC progression can be associated with the differentiation status of tumor cell before malignant transformation. Our aim was to investigate the dynamic expression of GPC3 during tumor cells differentiation and to explore the role and theoretical significance of GPC3 in malignant essence of HCC. METHODS: The expressions of tissue GPC3 and alpha-fetoprotein (AFP) were detected by immunohistochemical staining...

BACKGROUND: Despite new treatment options for hepatocellular carcinomas (HCC) recently, 5-year survival remains poor, ranging from 50 to 70%, which may attribute to the lack of early diagnostic biomarkers. Thus, developing new biomarkers for early diagnosis of HCC, is extremely urgent, aiming to decrease HCC-related deaths. METHODS: In the study, we conducted a comprehensive characterization of gene expression data of HCC based on a bioinformatics method. The results were confirmed by real time polymerase chain reaction (RT-PCR) and TCGA database to prove the credibility of this integrated analysis...

Local ablation therapy is considered as a conventional treatment option for patients with early stage hepatocellular carcinoma (HCC). Although radiofrequency (RF) ablation is widely used for HCC, the use of cryoablation has been increasing as newer and safer cryoablation systems have developed. The thermodynamic mechanism of freezing and thawing used in cryoablation is the Joule-Thomson effect. Cryoablation destroys tissue via direct tissue destruction and vascular-related injury. A few recent comparative studies have shown that percutaneous cryoablation for HCCs is comparable to percutaneous RF ablation in terms of long term therapeutic outcomes and complications...

BACKGROUND: Variation in survival in hepatocellular carcinoma (HCC) has been attributed to different aetiologies or disease stages at presentation. While international guidelines recommend surveillance of high-risk groups to permit early diagnosis and curative treatment, the evidence that surveillance decreases disease-specific mortality is weak. METHODS: We compared HCC survival figures from Japan (n=1174) and Hong Kong (n=1675) over similar time periods (Japan 2000-2013, Hong Kong, China 2003-2014)...

HCC represents the sixth most common cancer worldwide and the second leading cause of cancer-related death. Despite the high incidence, treatment options for advanced HCC remain limited and unsuccessful, resulting in a poor prognosis. Despite the major advances achieved in the diagnostic management of HCC, only one third of the newly diagnosed patients are presently eligible for curative treatments. Advances in technology and an increased understanding of HCC biology have led to the discovery of novel biomarkers...

Due to the features of strong heterogeneity, difficult early diagnosis, poor prognosis, and high fatality rate, hepatocellular carcinoma (HCC) has become an important disease which threatens the health of the Chinese population. Accurate early diagnosis is crucial to improving the success rate of liver cancer resection and reducing postoperative recurrence and metastasis, and its core is the screening and validation of biomarkers for early diagnosis. Isobaric tags for relative and absolute quantitation (iTRAQ) and stable isotope labeling with amino acids in cell culture are important parts of proteomics technology, and iTRAQ has become the most important technique in quantitative proteomics technology due to its advantages of high throughput, high quantitative accuracy, and no limitation by sample source...

OBJECTIVE: Hepatocellular carcinoma (HCC) is still one of the most common death-related malignancies worldwide. Because the way onset and progression are hidden most, HCC diagnoses are made at an advanced stage, when they are unsuitable for surgical resection. MicroRNAs are a class of small non-coding RNAs, participating in many aspects of cancers. In this study, we tried to establish the role of microRNA-718 (miR-718) in the malignant phenotype of HCC cells and its possible role in HCC diagnosis...

While intratumor heterogeneity contributes to disease progression, metastasis, and resistance to chemotherapy, it also provides a route to understanding the evolution and drivers of disease. Defects in epigenetic landscapes are intimately linked to pathogenesis of a variety of human diseases, with epigenetic deregulation promoting tumorigenesis. Understanding epigenetic heterogeneity is crucial in hepatocellular carcinoma (HCC), where epigenetic alterations are frequent, early, and pathogenic events. We determined genome-wide DNA methylation and copy number variation leveraging the Infinium 450 K in a series of regenerative nodules from within single patient livers...
