Linear array genotyping and hybrid capture II assay in detecting human papillomavirus genotypes in women referred for colposcopy due to abnormal Papanicolaou smear.

The main objective of this study was to assess the feasibility of human papillomavirus (HPV) genotyping in women referred for colposcopy due to abnormal Papanicolaou (Pap) smear. A series of 248 women referred for colposcopy due to an abnormal Pap smear were analysed with the Roche Linear Array HPV genotyping test detecting 37 most frequent HPV types, and compared with hybrid capture II (HCII) assay for oncogenic (high-risk [HR] HPV) types as well as for p16INK4a expression using immunocytochemistry. All tests were performed in cervical samples collected in PreservCyt liquid media for liquid-based cytology (ThinPrep), and colposcopic biopsy and/or loop electro excision procedure cone biopsy was used as the gold standard.

Detection of human papillomavirus genotypes among high-risk women: a comparison of hybrid capture and linear array tests.

Objectives: To assess the concordance and performance of 2 different assays in detection of human papillomavirus (HPV) genotypes among women with abnormal Pap smear.

Study Design: A series of 575 women referred for colposcopy due to an abnormal Pap smear were analyzed with the Linear Array HPV Genotyping test detecting 37 HPV types and compared with Hybrid Capture II (HCII) assay for detection of carcinogenic HPV. Histologic outcomes of cervical intraepithelial neoplasia grade 2 (CIN2) or worse (CIN2+) and CIN3+ were the primary endpoints.

P16(INK4a) immunocytochemistry in liquid-based cytology samples in equivocal Pap smears: added value in management of women with equivocal Pap smear.

Objective: To test whether p1l6(INK4a) immunocytochemistry (ICC) in liquid-based cytology (LBC) is useful with colposcopy in abnormal Pap smears.

Study Design: A series of 248 women with abnormal Pap smear were analyzed for oncogenic (HR) human papillomavirus (HPV) types using the Hybrid Capture II assay and for p16(INK4a) expression using ICC on cervical samples in PreservCyt liquid media. Colposcopic and loop electrosurgical excision procedure (LEEP) cone biopsy were the gold standard.

Performance of the Roche AMPLICOR human papillomavirus (HPV) test in prediction of cervical intraepithelial neoplasia (CIN) in women with abnormal PAP smear.

Objectives: To assess the performance of a novel PCR-based assay (Roche AMPLICOR HPV test) in detection of cervical pathology as a part of management for abnormal PAP smear (MAPS) and in women participating in cervical cancer screening.

Study Design: Altogether, 504 women comprising 270 patients referred for colposcopy due to an abnormal Pap smear and another 234 women participating in cervical cancer screening (tested for comparison) were analyzed for oncogenic (HR) Human papillomavirus (HPV) types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68 using the Roche AMPLICOR HPV test in cervical samples collected in PreservCyt liquid media. Colposcopic biopsy and/or LEEP cone biopsy was used as the gold standard in the triage group, while liquid-based cytology (LBC) was the reference test in the screening group.
