Early and long-term effects of prophylactic and post-excision human papillomavirus vaccination on recurrent high-grade cervical intraepithelial neoplasia relative to margin status: a retrospective cohort study in the Czech Republic.

ABSTRACT:

Background

The effect of human papillomavirus (HPV) vaccination on cervical intraepithelial neoplasia grade 2 or worse (CIN2+) recurrence with respect to cone margin positivity is unknown. Most studies assessed this effect beyond two months post-conisation. We aimed to determine both the duration and early onset of effect in women who had been prophylactically vaccinated or vaccinated after conisation, considering cone margin status.

Methods

This cohort study used data from one of the central laboratories in the Czech Republic, covering approximately 33% of women undergoing national cervical cancer screening. It included women treated for CIN2+ between 2010 and 2024 who had received either prophylactic HPV vaccination (available through the national immunisation program sinc
