| Abstract | BACKGROUND: The Hybrid Capture II high-risk human papillomavirus (hrHPV) DNA test is a US Food and Drug Administration-approved nucleic acid hybridization assay using chemiluminescence for the semiquantitative detection of hrHPV in cervical samples. Patient samples and controls are used to calculate results as negative for hrHPV if <1.0, positive for hrHPV if >2.5, and 'equivocal' if between 1.0 and 2.5. METHODS: The authors reported on the cervical histologic results of 209 patients demonstrating 'equivocal' results for hrHPV from SurePath (204 patients) or ThinPrep (5 patients) vials, and compared patients in this cohort with atypical squamous cells of undetermined significance (ASC-US) cytology on the index cervical Papanicolaou (Pap) test (Group 1; n = 148 patients) with a patient cohort demonstrating unequivocal positive hrHPV test results (Group 2; n = 148 patients). The chemiluminescence intensity of hrHPV tests from patients in Group 2 were correlated with the presence and severity of dysplasia on subsequent histologic results, and patients were thereby stratified for their subsequent risk of cervical intraepithelial neoplasia (CIN) types II/III. RESULTS: Approximately 97% of hrHPV tests demonstrating 'equivocal' results were found to be positive at the time of retesting, and 15% of biopsied cases demonstrated CIN II or III. Results of follow-up histology after an ASC-US diagnosis, expressed as a percentage of the biopsied cohort, were: CIN II/III: 16.5% in Group 1 and 22.4% in Group 2; CIN I: 27% in Group 1 and 23.5% in Group 2; and negative: 56.5% in Group 1 and 54.1% in Group 2. Chemiluminescence intensity did not appear to be correlated with the severity of dysplasia. CONCLUSIONS: The percentage of high-grade CIN in the 'equivocal' hrHPV cohort is highly significant and therefore the management of these patients should be similar to the unequivocally positive population. After an unequivocal positive hrHPV test, the hrHPV chemiluminescence intensity does not appear to further predict the rate of high-grade CIN. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
