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.


OBJECTIVE
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.


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


CONCLUSIONS
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.
