Certain types of the human papilloma virus (HPV) are well established as the primary cause of cervical cancer. Several studies have shown that HPV testing can improve the detection rate of high-grade cervical intraepithelial neoplasia (CIN), but these have been carried out primarily in younger women. In this study we evaluated the role of HPV testing as an(More)
BACKGROUND Certain types of human papillomavirus (HPV) are the primary cause of almost all cervical cancers. HPV testing of cervical smears is more sensitive but less specific than cytology for detecting high-grade cervical intraepithelial neoplasia (CIN2+). HPV testing as a primary screening approach requires efficient management of HPV-positive women with(More)
Women referred for colposcopy with mild and moderate dyskaryosis and found to have only minor cervical abnormalities were screened for oncogenic human papilloma virus (HPV) types. The natural development of these abnormalities in 42 HPV-positive women was assessed by cytology and colposcopy at 6-month intervals for up to 2 years. As is the case with cancers(More)
Cervical scrapes from 116 British women referred with cervical cancer were tested for the presence of high oncogenic risk human papillomavirus (HPV) genotypes (HPV(hr)). Ninety-four per cent of the scrapes had one or more of these virus types and 66% were HPV16-positive. HPV18 was more frequent in adenocarcinoma. No evidence was found for an increased(More)
BACKGROUND The detection of high-risk human papillomavirus (HPV) DNA provides higher sensitivity but lower specificity than cytology for the identification of high-grade cervical intraepithelial neoplasia (CIN). This study compared the sensitivity and specificity of several adjunctive tests for the detection of high-grade CIN in a population referred to(More)
High-risk human papillomavirus (HPV) DNA/RNA testing provides higher sensitivity but lower specificity than cytology for the identification of high-grade cervical intraepithelial neoplasia (CIN). Several new HPV tests are now available for this purpose, and a direct comparison of their properties is needed. Seven tests were evaluated with samples in liquid(More)
BACKGROUND Several new assays have been developed for high-risk HPV testing of cervical samples; we compare six HPV tests in a screening population. METHODS Residual material from liquid-based PreservCyt samples was assayed. Four tests (Hybrid Capture 2, Cobas, Abbott and Becton-Dickinson (BD)) measured HPV DNA while two used RNA (APTIMA and NorChip). (More)
Several studies have shown that HPV testing is substantially more sensitive than cytology for primary cervical screening. However, less data exist concerning the duration of protection afforded by a negative HPV test compared to a normal cytological outcome. Here we report the long-term findings from the Hammersmith study in women aged 35 or more. HPV(More)
AIM To compare triage strategies using different human papillomavirus (HPV) consensus and genotyping tests and a p16(INK4a) test. METHODS 1228 women referred with a borderline or single mildly dyskaryotic smear. Samples were taken at colposcopy using PreservCyt. Tests included Hybrid Capture 2, Abbott RealTime PCR, BD HPV, Cobas 4800, PreTect HPV-Proofer,(More)
HPV DNA testing is known to be much more sensitive than cytology, but less specific. A range of HPV and related tests in 858 women referred for colposcopy because of an abnormal smear were evaluated to compare the performances of these tests. This article compared the Abbott test to other tests which had been previously evaluated. This test was a real true(More)
