Comparison of cervical cancer screening by self-sampling papillomavirus test versus pap-smear in underprivileged women in France

BACKGROUND

The purpose of this study was to compare cervical cancer screening by pap smear (PS) versus preliminary HPV testing based on self-collected samples (SC-HPV).

METHODS

Interventional study among underprivileged women from 25 to 65 years old in four French cities. The control group (CG) was referred for a PS. The experimental group (EG) conducted a SC-HPV test followed by a PS in case of positivity. Differences on screening completion and cytological abnormalities were analysed by logistic and Cox regression.

RESULTS

383 women were assigned to the EG and 304 to the CG. The screening completion proportion was 39.5% in the CG compared to 71.3% in the EG (HR = 2.48 (CI 95% [1.99-3.08]; p < 0.001). The proportion of cytological abnormalities was 2.0% in the CG and 2.3% in the EG (OR = 1.20 (CI 95% [0.42-3.40]; p = 0.7). The proportion of participants lost to follow-up was 60.5% in the CG and 63.2% in the EG HPV positive (p = 0.18).

CONCLUSION

Providing an SC-HPV-test increased the participation of underprivileged women in CCS. Nevertheless, the significant number of lost to follow-up in both groups can undermine the initial benefits of the strategy for HPV positive women. Registration: Clinicaltrials.gov: NCT03118258.
