Evaluation of the Impact of Human Papillomavirus DNA Self-sampling on the Uptake of Cervical Cancer Screening.

Background: The rate of uptake of the Papanicolaou (Pap) smear is generally low. Its causal relationship with human papillomavirus (HPV) DNA allows HPV DNA self-sampling to be used as an alternative screening tool for cervical cancer.

Objectives: This study explored the acceptability of HPV DNA self-sampling and its impact on the rate of compliance with cervical cancer screening.

Methods: A crossover randomized clinical trial was conducted in community-based clinics. Participants were allocated to 1 of the following 2 arms: arm 1: self-sampling before a Pap smear; and arm 2: a Pap smear before self-sampling. After completing the 2 screening methods, participants in each arm took part in face-to-face interviews using standardized, structured questionnaire.

Results: The participants accepted both self-sampling (7.7/10) and a Pap smear (7.8/10) for cervical cancer screening. However, participants without previous experience of Pap smears or who had more than 2 sexual partners preferred self-sampling (P < .05). The participants expressed overall positive feelings toward self-sampling, and there was good agreement in HPV detection between the 2 screening methods (κ = 0.65). We estimate that the introduction of HPV DNA self-sampling could increase the future rate of uptake of cervical cancer screening by 6.5% and would entail lower costs.

Conclusion: Human papillomavirus DNA self-sampling could be an alternative screening method to increase the coverage of cervical cancer screening.

Implications For Practice: Human papillomavirus DNA self-sampling could overcome the barriers raised by Pap smears and enhance the coverage of cervical cancer screening. Promotional publicity and education are essential.
