Abstract
A recent review by Aguayo appearing in Infectious Agents and Cancer gave a timely overview of viruses that have been associated with human breast cancer. In this Matters Arising article, we discuss some critical additional points and concerns that are pertinent for this important and contentious research focus, in particular as it pertains to the involvement of the retrovirus mouse mammary tumor virus and its closely related human betaretrovirus form. This includes additional evidence for zoonotic as well as horizontal transfer of the virus and also odds ratio data on the likelihood of an involvement of the viruses proposed to be involved in human breast cancer. In our opinion, this information redresses the balance of the Aguayo review article and make a much more compelling case for this retrovirus being one of the causes of human breast cancer.Clinical trial number Not applicable.
期刊介绍:
Infectious Agents and Cancer is an open access, peer-reviewed online journal that encompasses all aspects of basic, clinical, epidemiological and translational research providing an insight into the association between chronic infections and cancer.
The journal welcomes submissions in the pathogen-related cancer areas and other related topics, in particular:
• HPV and anogenital cancers, as well as head and neck cancers;
• EBV and Burkitt lymphoma;
• HCV/HBV and hepatocellular carcinoma as well as lymphoproliferative diseases;
• HHV8 and Kaposi sarcoma;
• HTLV and leukemia;
• Cancers in Low- and Middle-income countries.
The link between infection and cancer has become well established over the past 50 years, and infection-associated cancer contribute up to 16% of cancers in developed countries and 33% in less developed countries.
Preventive vaccines have been developed for only two cancer-causing viruses, highlighting both the opportunity to prevent infection-associated cancers by vaccination and the gaps that remain before vaccines can be developed for other cancer-causing agents. These gaps are due to incomplete understanding of the basic biology, natural history, epidemiology of many of the pathogens that cause cancer, the mechanisms they exploit to cause cancer, and how to interrupt progression to cancer in human populations. Early diagnosis or identification of lesions at high risk of progression represent the current most critical research area of the field supported by recent advances in genomics and proteomics technologies.
