Background:
Human papillomavirus (HPV) testing may be feasible for primary cervical cancer screening in low-resource countries.
Objective:
To compare self-sampling by women with clinician-performed sampling for HPV testing in Africa.
Search Strategy:
MEDLINE, Google scholar, EMBASE, and several journals were searched from 2000 until 2015 using relevant terms.
Selection Criteria:
Selected studies compared self-sampled and clinician-sampled HPV tests.
Data Collection And Analysis:
Data extraction forms included description of the type of HPV screening, description of any additional intervention components, study design, sample size, follow-up periods, analytic approach, reported numerical outcomes, results, and limitations.
Results:
Twenty-five studies were identified. Women of a wide age range were successful at self-sampling in many African countries. More than 95% of self-samples yielded HPV DNA results. The concordance in test results between self-collected samples and clinician-collected samples was reasonably high in most studies. In all studies, the quality of cytology from self-sampling matched that of clinician-sampling. Women were generally positive about self-collection, but noted some concerns.
Conclusion:
Self-sampling for HPV DNA testing seems to represent a feasible alternative to the Pap test. Further research is needed to provide a solid evidence base to inform using of self-sampling for HPV DNA testing for primary cervical cancer screening.
