High Risk Hpv

Most uterine cervical cancers are caused by the persistent infection of the high-risk human papillomavirus (hrHPV). Thus, the hrHPV-DNA test, which examines specimens from the cervix, is the standard screening method as well as cytology in western countries. Urine sampling for the hrHPV-DNA test would be easier and help improving screening rates. This study prospectively investigated the concordance between urine and cervical hrHPV tests for patients with atypical squamous cells of undetermined significance (ASC-US) in cervical cytology. We recruited 338 women with the cytologic diagnosis of ASC-US and performed hrHPV-DNA tests to both samples from the uterine cervix and first void urine, using the Cobas 4800 system. In all hrHPV genotypes, the simple concordance rate was 90.8% (307/338) and the Kappa statistic value was 0.765, which shows substantial concordance. The positive concordance rate was 70.5% (74/105), which was the rate excluding women who had negative results in both tests. When limited to types 16 and 18, the simple concordance rate was 98.8% (334/338), and the Kappa statistical value was calculated to be 0.840, which showed almost perfect concordance. The positive concordance rate resulted in 81.8% (18/22). We conclude that the urine hrHPV-DNA test could substitute the cervical test in women with ASC-US.

Abstract Objective.—To determine whether human papillomavirus (HPV) testing is useful in the evaluation of patients diagnosed with atypical squamous cells of undetermined significance (ASCUS)/low-grade squamous intraepithelial lesion (LSIL) and whether the HPV test is appropriate as an alternative screening method. Design.—The results of Papanicolaou (Pap) tests and subsequent hybrid capture tube (HCT) II tests for high-risk–type HPV were analyzed for 457 patients. Among these tests, 208 histologic diagnoses were made and correlated with the results of Pap and HPV tests. The sensitivity and specificity of the Pap test, HPV test, and the combined method of Pap and HPV tests to detect cervical intraepithelial neoplasia (CIN) 2/3 and all CIN were also measured. Results.—Sixty (63.8%) of 94 women with LSIL and 31 (26.3%) of 118 women with ASCUS tested positive for high-risk HPV. The sensitivity values for Pap tests in detecting all cases of CIN and CIN 2/3 were 91.4% and 92.9%, respectively. The sensitivity values of HCT II tests using the high-risk probe for detecting all cases of CIN and CIN 2/3 were 62.6% and 88.1%, respectively. Biopsies confirmed that 10 (22.7%) of 44 LSIL patients with high-risk HPV had CIN 2/3, but only 1 (4.5%) of 22 LSIL patients without high-risk HPV had CIN 2/3. Conclusion.—Testing for high-risk HPV with the HCT II test is useful in the detection of CIN 2/3 in LSIL groups and in the selection of patients for colposcopy in ASCUS groups, but it is not suitable for cervical cancer screening tests.

Aim:To evaluate the role of p16INK4a immunoexpression and human papillomavirus (HPV) DNA test for the detection of dyskaryotic cells in high-risk women.Materials and Methods:This work was a retrospective diagnostic study conducted in the University Hospital of Thessaloniki from January to December 2008. The subjects were women with current or previous HPV infection and current or previous cervical intraepithelial lesion (with or without treatment) or clinical warts. All liquid-based cytological samples were tested for P16INKa and HPV DNA test. The accuracy parameters used for the outcome included sensitivity, specificity, and positive predictive value.Results:A total of 226 women were included; the mean age was 29 years. Expression of p16INK4a was detected in the cytological samples of 13% of the negative cases, 44% of the cases of atypical squamous cells of undetermined significance, 46% of the cases of low-grade squamous intraepithelial lesion, and 78% of the cases of high-grade squamous intraepithelial lesion. A total of 91 women tested positive for high-risk HPV infection, and 54 of those had p16INK4a-positive staining reaction cells. The concordance between the 2 tests, HPV DNA and p16, was 59% regarding infection-positive cases. Diffuse strong parabasal p16INK4a immunostaining (nuclear score >2) was observed in 17 cases of the abnormal cytological findings (atypical squamous cells of undetermined significance, 2 cases; low-grade squamous intraepithelial lesion, 8 cases; high-grade squamous intraepithelial lesion, 7 cases). Colposcopy-directed biopsies were used as the criterion standard for the detection of cervical intraepithelial neoplasia in 91 women. The sensitivity of p16INK4a was 95% and the specificity was 92%, whereas the sensitivity of high-risk HPV was 100% and the specificity was 78%. The positive predictive value of p16INK4a was 71%, whereas that of HPV DNA was 44%.Conclusion:The findings suggest that p16INK4a immunostaining can improve the accuracy of cytological examination and HPV DNA test and may be particularly useful in the triage of low-grade lesions.

Objective: Persistence of high-risk HPV infection is known to be the major cause of cervical cancer. It is important to differentiate the genotype of HPV infection, whether it is high, intermediate or low risk. The aim of this study was to assess the prevalence of high-risk HPV types among Indonesian women with negative VIA. Method: We analyzed cervical swabs from 1,214 patients with negative VIA. By using INNO-Lipa HPV DNA test, we detected the HPV DNA and its genotype. Result: From the 1,214 women with negative VIA, 48 (3.95%) samples were confirmed to have positive HPV DNA by using PCR and electrophoresis. However, hybridization test were not able to detect HPV genotypes in 9 samples. These 9 samples were tested again with PCR and electrophoresis and resulted in negative HPV DNA. Among the remaining 39 samples (3.21%), we detected 19 types of HPV, consisting of 13 types of high-risk HPV, 5 types of low-risk HPV, and 1 type of unknown HPV (type X). Conclusion: Among patients with negative VIA, 3.21% was found to be positive for HPV DNA. From this percentage, the prevalence of high-risk HPV is higher than the low-risk and unknown HPV. Therefore we cannot ignore results of negative VIA, particularly in highrisk group, because there is a slight possibility that presence of HPV can be identified, especially the high risk ones which have a tendency to be persistent. We support the importance of HPV DNA test as cervical cancer screening method. [Indones J Obstet Gynecol 2014; 3: 153-156] Keywords: cervical cancer, high-risk HPV, negative VIA

PURPOSE Cervical cancer screening is one of the strategies to prevent the disease among women at risk. Human papillomavirus (HPV) DNA testing is increasingly used as the cervical cancer screening method because of its high sensitivity. Self-collection of cervical specimens has the potential to improve participation. However, there is only limited information on comparison between self-collected and provider-collected samples with regard to detection of high-risk HPV using the careHPV method. The study aimed to compare HPV detection by careHPV in self-collected and provider-collected cervical samples and to assess the acceptability of self-collection techniques. MATERIAL AND METHODS Women attending cervical cancer screening clinics at Ocean Road Cancer Institute, Kilimanjaro Christian Medical Centre or Mawenzi Hospital in Tanzania were included in the study. They underwent a face-to-face interview, HIV testing, and collected a self-sample using Evalyn Brush. Subsequently, they had a cervical sample taken by a health provider. Both samples were tested for high-risk HPV DNA using careHPV. RESULTS Overall, 464 women participated in the study. The high-risk HPV prevalence was 19.0% (95% CI, 15.6 to 22.9) in the health provider samples, but lower (13.8%; 95% CI, 10.9 to 17.3) in the self-collected samples. There was a good overall agreement 90.5% (95% CI, 87.5 to 93.0) and concordance (κ = 0.66; 95% CI, 0.56 to 0.75) between the two sets of samples. Sensitivity and specificity were 61.4% (95% CI, 50.4 to 71.6) and 97.3% (95% CI, 95.2 to 98.7), respectively, varying with age. Most women preferred self-collection (79.8%). CONCLUSION Overall, self-sampling seems to be a reliable alternative to health-provider collection and is acceptable to the majority of women. However, instructions on proper procedures for sample collection to the women are important.
