Abstract

Cervical cancer (CC) is a preventable disease and treatable cancer. Most of the new cases and deaths from CC occur in Low- and Middle-Income Countries (LMICs) due to cultural and systematic barriers leading to low CC screening uptake. In recent years, self-sampling has been proposed as a method to increase CC screening uptake and is slowly being implemented into screening programmes worldwide. Simultaneously, DNA methylation has been proposed as a novel biomarker that could be used for the triage of self-collected samples that test positive for high-risk types of Human Papillomavirus (HPV). In this paper, we conducted a literature review of studies assessing the efficacy of DNA methylation markers to detect Cervical Intraepithelial Neoplasia (CIN) in self-collected cervicovaginal swabs or urine (2019-2024). Our review showed that, of the available data, DNA methylation together with self-sampling could perform as well as cytology in the detection of CIN as well as improve uptake of CC screening and reduce loss to follow up, especially in LMICs. However, more data is still needed to understand which methylation tests are most efficacious. Future studies should assess the full potential of DNA methylation and self-sampling in large, diverse screening cohorts.

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.
