Evaluation of the Cobas® 4800 HPV Test for the Detection of High-grade Cervical Disease in Women Undergoing Routine Cervical Cancer Screening

This study provided data on the performance of the Cobas® 4800 HPV Test for identifying histologically confirmed high-grade cervical disease. The baseline, cross-sectional phase was conducted in approximately 45,000 women undergoing routine cervical cancer screening, of whom approximately 7,400 were selected to undergo colposcopy and biopsy/endocervical curettage (ECC) at baseline. These subjects included women with cytology that is 'not normal' and a selection of those with 'normal' cytology who entered a follow-up phase and underwent cytological evaluation annually for 3 years. In this follow-up phase, colposcopy and biopsy/ECC were performed only in women with cervical cytology considered 'not normal' at any of the annual follow-up visits.

The cobas 4800 human papillomavirus (HPV) Test combines in a single assay the identification of pooled high-risk oncogenic HPV types (31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68), as well as genotypes 16 and 18 individually.

A diagnosis of ≥ CIN2 (cervical intraepithelial neoplasia) included histology results of CIN2, CIN3, adenocarcinoma in situ, squamous cell carcinoma, or adenocarcinoma. The diagnosis was based on central pathology review.

A diagnosis of ≥ CIN3 (cervical intraepithelial neoplasia) included histology results of CIN3, adenocarcinoma in situ, squamous cell carcinoma, or adenocarcinoma. The diagnosis was based on central pathology review.
