Alternatives to surveillance for persistent human papillomavirus after a positive cervical screen: A systematic review and meta-analysis

Objectives

In 2021, the World Health Organisation (WHO) updated its guidelines for cervical screening from cytology testing to primary high-risk human papillomavirus (HR-HPV) testing. This change in testing has effectively led to a ‘new disease’ as women are now aware of having a virus that induces changes that can cause cancer, which they would have been unaware of previously. While current management involves a ‘watch and wait’ approach and no active treatment, the anxiety associated with having HR-HPV may prompt some women to seek ‘treatments’ outside the screening programme.

● to identify potential treatment options available for women with persistent HR-HPV and/or low-grade cervical intraepithelial neoplasia (CIN), i.e. ≤CIN 1.

● to determine the clinical effectiveness of these treatments, namely by:

 ◦ HR-HPV clearance rate, and/or:

 ◦ CIN regression.

Methods

We searched MEDLINE, PubMed, EMBASE, Web of Science and the Cochrane Library. We included cohort studies and randomised controlled trials (RCTs) only. Records (n = 2135) were screened in Rayyan by two independent reviewers. Quality assessment was conducted using the ROBINS-I tool and the ROB-2 tool.

Results

12 studies (four cohort studies and eight RCTs) were included: six oral medications, two topical medications, one vaccination, and three non-surgical device treatments. Meta-analysis revealed that some therapeutic interventions, including vaginal gels, photodynamic therapy, and some oral medications, may lead to earlier resolution of persistent HR-HPV and regression of low-grade CIN when compared with natural clearance.

Conclusion

This review can better inform discussions with HR-HPV+ women and answer their questions about alternatives to surveillance.
