Background: The aim of this multicentric study was to identify human papillomavirus (HPV) type distribution in invasive cervical cancer and high-grade cervical intraepithelial neoplasia 2/3 (CIN2/3) in Italy.
Methods: Cases were sampled through the electronic databases at the pathology units of eight centers in six regions from central and southern Italy. HPV types were detected from paraffin-embedded tissue samples and cervical specimens through amplification of HPV DNA with GP5+/GP6+ primers, followed by genotyping with reverse line blot (RLB). Untyped HPV-positive samples were sequenced. HPV-negative samples underwent nested PCR, followed by either RLB or sequencing. Finally, the remaining HPV-negative samples were amplified with primers targeting the virus E6 to E7 regions.
