Impact of HPV Vaccination on Cervical High Grade Lesions in France

The objective is to estimate the prevalence of the different genotypes of human papillomaviruses (HPV) in histologically proven high-grade lesions of the cervix in patients born between 1972 and 1993. It is plan to determine if the prevalence of HPV16 and HPV18 is lower in the population born between 1983 and 1993 and potentially exposed to HPV vaccination compared to those born between 1972 and 1982 who were not exposed to vaccination. Thus the investigators should be able to determine whether the introduction of HPV vaccination in France in 2007 has had an impact on the development of high-grade lesions associated with HPV16 and HPV18.
