Summary
Hepatitis C virus (HCV) is linked to B-cell non-Hodgkin lymphoma, particularly diffuse large B-cell lymphoma. Antiviral therapy response suggests a causative role, though mechanisms require further study.
Area of Science:
- Hepatology
- Oncology
- Virology
Background:
- Hepatitis C virus (HCV) is a known cause of viral hepatitis.
- Emerging evidence links HCV infection to B-cell non-Hodgkin lymphoma (NHL).
- This association is supported by epidemiological, biological, and clinical data.
Purpose of the Study:
- To review the evidence linking HCV infection to B-cell NHL.
- To discuss the potential pathophysiological mechanisms involved.
- To examine the role of antiviral therapy in HCV-associated lymphomas.
Main Methods:
- Review of epidemiological studies.
- Analysis of biological and in vitro/in vivo studies.
- Evaluation of clinical data on antiviral therapy outcomes.
Main Results:
- HCV is associated with specific B-cell NHL subtypes, including diffuse large B-cell lymphoma, small lymphocytic lymphoma/chronic lymphocytic leukemia, and marginal zone lymphoma.
- Antiviral therapy shows positive responses in some HCV-positive lymphoma patients.
- Evidence suggests both direct viral infection and indirect mechanisms (sustained antigenic stimulation) may contribute to lymphomagenesis.
Conclusions:
- HCV infection is strongly associated with B-cell NHL.
- While direct viral infection is possible, indirect mechanisms involving chronic inflammation and immune dysregulation are likely key.
- Further research is needed to fully elucidate the complex relationship and optimize treatment strategies.

01:25Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
01:51Mechanisms of Retrovirus-induced Cancers
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
