Infection and Cancer: The Case of Hepatitis B REVIEW ARTICLES

This article is divided into four parts: In the first part, an overview is given on the epidemiologic data and risk factors of HCC development in patients with chronic hepatitis B. In the second part, recent progress on the anti-HBV strategies for preventing HCC is updated. In the third part, approaches to improve the outcomes of established HBV-related HCC are covered. These methods include surveillance strategies to identify asymptomatic HCC among patients with chronic HBV infection, and use of antiviral treatment to avoid HBV reactivation during treatment for HCC and reduce the recurrence of HCC after curative treatment. Finally, the status of the development of targeted drugs specifically for HBV-related HCC is discussed in the section on future development.

AbstractBackgroundHost genome integration of HBV sequence is considered to be significant in HBV antigen expression and the development of hepatocellular carcinoma (HCC).MethodWe developed a probe-based capture strategy to enrich integrated HBV DNA for deep-sequencing analysis of integration sites in paired patient samples derived from tumor, liver tissue adjacent to tumor, saliva and plasma, as a platform for exploring the correlation, significance and utility of detecting integrations in these sample types.ResultsMost significantly, alpha fetoprotein levels significantly correlated to the amounts of integrations detected...

Abstract PURPOSE: Hepatocellular carcinoma (HCC) is the seventh most commonly diagnosed cancer and the fourth-leading cause of cancer-related death worldwide. Chronic hepatitis B virus (HBV) is the leading cause of HCC in China. Emerging evidence suggests that long noncoding (lnc)-RNAs are deregulated and are involved in the development of HCC. Our previous study found that HBV X protein can promote HCC by altering lncRNA expression profiles. The purpose of this study was to investigate the expression of the lncRNA semaphorin 6A-antisense RNA 1 (SEMA6A-AS1) and its prognostic value in HBV-related HCC. METHODS...

ConclusionsMVI status definitely helps select treatment options in HBV+ rHCC patients. For MVI( −) patients, RR/RFA provided better survival than TACE while for MVI(+) patients, TACE shared similar survival outcomes.Key Points• This study aimed at the determination of the optimal treatment options (ablation /resection vs TACE) in case of recurrent HBV-related HCC.• It showed that MVI status, established at primary resection of HCC, was a powerful marker for selecting the best treatment option in these patients.• In MVI(−) patients, RR/RFA achieved a better survival than TACE. In MVI(+) patients, ...

n Lee Chen Tyan Hepatocellular carcinoma (HCC) is among the ten most commonly diagnosed cancers and the fourth leading cause of cancer-related death. Patients with hepatitis B virus (HBV) infection are prone to developing chronic liver diseases (i.e., fibrosis and cirrhosis), and the HBV X antigen plays an important role in the development of HCC. The difficulty in detecting HCC at the early stages is one of the main reasons that the death rate approximates the incidence rate. The regulators controlling the downstream liver protein expression from HBV infection are unclear. Mass spectrometric techniques and cu...

Hepatitis B Virus (HBV), a prototype of hepadnaviral family, is a highly oncogenic virus and its integration to human hepatocyte genome is considered to be a decisive driver of liver carcinogenesis culminating in the onset of primary liver cancer, hepatocellular carcinoma (HCC) [1]. Mechanisms of HBV integration are not well defined and those enabling the earliest (initial) virus-host DNA fusions are essentially unknown. This impedes our understanding of the initiation and molecular dynamic of progression of HBV-associated oncogenesis.

The characteristics and associated biological functions of highly mutated genes, in which the mutation frequencies are at least 5% in HCC patients with HBV infection, are evaluated in the study, and these results could enrich our understanding of highly mutated genes and their relationships with HBV ‐related HCC. AbstractGene mutation is responsible for the development of hepatocellular carcinoma (HCC) with hepatitis B virus (HBV) infection; however, the characteristics and associated biological functions of highly mutated genes, in which the mutation frequencies are at least 5% in HCC patients with HBV infection, are no...

ConclusionA substantial further reduction in cases of HCC requires a wider application of universal HBV vaccination and effective treatment of HBV- and HCV-related chronic hepatitis and cirrhosis, more effective campaigns to favor correct dietary habits and reduce alcohol consumption and the intensification of studies on HCC pathogenesis for future optimized prevention strategies.

n Patel The hepatitis B virus (HBV) chronically infects over 250 million people worldwide and is one of the leading causes of liver cancer and hepatocellular carcinoma. HBV persistence is due in part to the highly stable HBV minichromosome or HBV covalently closed circular DNA (cccDNA) that resides in the nucleus. As HBV replication requires the help of host transcription factors to replicate, focusing on host protein–HBV genome interactions may reveal insights into new drug targets against cccDNA. The structural details on such complexes, however, remain poorly defined. In this review, the current literat...
