Worldwide use of HPV self-sampling for cervical cancer screening

An increasing body of evidence supports the validity of self-sampling as an alternative to clinician collection for primary Human Papillomavirus (HPV) screening. Self-sampling effectively reaches underscreened women and can be a powerful strategy in low-and high-resource settings for all target ages. This work aims to summarize the current use of HPV self-sampling worldwide. It is part of a larger project that describes cervical cancer screening programmes and produces standardized coverage estimates worldwide. A systematic review of the literature and official documents supplemented with a formal World Health Organisation country consultation was conducted. Findings show that the global use of HPV self-sampling is still limited. Only 17 (12%) of countries with identified screening programs recommend its use, nine as the primary collection method, and eight to reach underscreened populations. We identified 10 pilots evaluating the switch to self-sampling in well-established screening programs. The global use of self-sampling is likely to increase in the coming years. COVID-19's pandemic has prompted efforts to accelerate HPV self-sampling introduction globally, and it is now considered a key element in scaling up screening coverage. The information generated by the early experiences can be beneficial for decision making in both new and existing programs.

Automated summary

Self-sampling for HPV screening is increasingly recognized as a valid alternative to clinician collection, reaching underscreened women effectively. The global use of HPV self-sampling is currently limited, but efforts are being made to increase its adoption in the coming years. The COVID-19 pandemic has accelerated the introduction of HPV self-sampling as a key element in expanding screening coverage.
