Abstract
Cervical cancer seriously affects the health of women worldwide. Persistent infection of high-risk HPV (Human Papilloma Virus) can lead to cervical cancer. There is a great need for timely and efficient screening methods for cervical cancer. The current screening methods for cervical cancer are mainly based on cervical cytology and HPV testing. Cervical cytology is made of Pap smear and liquid-based cytology, while HPV testing is based on immunological and nucleic acid level detection methods. This review introduces cervical cancer screening methods based on cytology and human papillomavirus testing in detail. The advantages and limitations of the screening methods are also summarized and compared.

Enhancing Cervical Cancer Screening with 7-Type HPV mRNA E6/E7 Testing on Self-Collected Samples: Multicentric Insights from Mexico. Cancers (Basel) 2024; 16:2485. [PMID: 39001547 PMCID: PMC11240307 DOI: 10.3390/cancers16132485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2024] [Revised: 07/01/2024] [Accepted: 07/05/2024] [Indexed: 07/16/2024] Open
Abstract
Cervical cancer remains a significant public health issue, particularly in regions with low screening uptake. This study evaluates the effectiveness of self-sampling and the 7-type HPV mRNA E6/E7 test in improving cervical cancer screening outcomes among a referral population in Mexico. A cohort of 418 Mexican women aged 25 to 65, referred for colposcopy and biopsy due to abnormal cytology results (ASC-US+), participated in this study. Self-samples were analyzed using both the 14-type HPV DNA test and the 7-type HPV mRNA E6/E7 test. The study assessed the sensitivity, specificity, positive predictive value (PPV), and the necessity of colposcopies to detect CIN3+ lesions. Participant acceptability of self-sampling was also evaluated through a questionnaire. The 7-type HPV mRNA E6/E7 test demonstrated equivalent sensitivity but significantly higher specificity (77.0%) and PPV for CIN3+ detection compared to the 14-type HPV DNA test (specificity: 45.8%, p < 0.001). The use of the HPV mRNA test as a triage tool reduced the number of colposcopies needed per CIN3+ case detected from 16.6 to 7.6 (p < 0.001). Self-sampling was highly accepted among participants, with the majority reporting confidence in performing the procedure, minimal discomfort, and willingness to undertake self-sampling at home. Self-sampling combined with the 7-type HPV mRNA E6/E7 testing offers a promising strategy to enhance cervical cancer screening by improving accessibility and ensuring precise diagnostics. Implementing these app roaches could lead to a significant reduction in cervical cancer morbidity and mortality, especially in underserved populations. Future research should focus on the long-term impact of integrating these methods into national screening programs and explore the cost-effectiveness of widespread implementation.

Abstract
Human papillomavirus (HPV) is a virtually necessary cause of cervical cancer, and HPV genotypes are categorized either as high-risk or low-risk based on their potential to cause malignancy of the cervix. HPV-DNA detection is used widely for screening women at risk. However, its clinical significance is not proven sufficiently in pregnancy. The aim of this review was to summarize published data referring to the integration of the HPV-DNA test in cervical cancer screening during pregnancy. PubMed and Scopus were searched for articles investigating the HPV-DNA test during pregnancy as a primary association; greater interest was placed on studies published after 2000. Retrieved articles reported similarities or discrepancies in the HPV-DNA test in pregnant women compared to those who are not pregnant, its accuracy, and its integration in cervical cancer screening. The HPV-DNA test may constitute a helpful tool utilized for monitoring, risk stratification, and triage of cases that require colposcopy. If combined with the HPV-mRNA test, this might improve its specificity. However, when compared to HPV-DNA detection rates in non-pregnant women, the results were ambiguous, without giving the opportunity to draw safe conclusions. Both those findings and the high cost hold it back from wide use. Hence, the Papanicolaou smear (Pap smear) is still the first-line diagnostic tool and colposcopy-guided cervical biopsy is the "gold standard" method for the management of cervical intraepithelial neoplasia (CIN) treatment during pregnancy.

Abstract
PURPOSE Cervical cancer (CC) is caused by a persistent high-risk human papillomavirus (hrHPV) infection. The cervico-vaginal microbiome may influence the development of (pre)cancer lesions. Aim of the study was (i) to evaluate the new CC screening program in Germany for the detection of high-grade CC precursor lesions, and (ii) to elucidate the role of the cervico-vaginal microbiome and its potential impact on cervical dysplasia. METHODS The microbiome of 310 patients referred to colposcopy was determined by amplicon sequencing and correlated with clinicopathological parameters. RESULTS Most patients were referred for colposcopy due to a positive hrHPV result in two consecutive years combined with a normal PAP smear. In 2.1% of these cases, a CIN III lesion was detected. There was a significant positive association between the PAP stage and Lactobacillus vaginalis colonization and between the severity of CC precursor lesions and Ureaplasma parvum. CONCLUSION In our cohort, the new cervical cancer screening program resulted in a low rate of additional CIN III detected. It is questionable whether these cases were only identified earlier with additional HPV testing before the appearance of cytological abnormalities, or the new screening program will truly increase the detection rate of CIN III in the long run. Colonization with U. parvum was associated with histological dysplastic lesions. Whether targeted therapy of this pathogen or optimization of the microbiome prevents dysplasia remains speculative.

Cancer Manag Res 2021; 13:6869-6877. [PMID: 34512026 PMCID: PMC8421554 DOI: 10.2147/cmar.s328279] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Accepted: 08/30/2021] [Indexed: 01/16/2023] Open
Abstract
Purpose To investigate the prevalence of precancers [high-grade squamous intraepithelial lesion (HSIL) and adenocarcinoma in situ (AIS)] and cancers [squamous cell carcinoma (SCC) and adenocarcinoma (ADC)] in various high-risk human papillomavirus (hrHPV) genotypes or age groups among women with negative for intraepithelial lesion or malignancy (NILM) and hrHPV-positive pap results. Materials and Methods In total, 26,228 women with NILM/hrHPV+ were included in the study. Among them, 5893 had immediate follow-up biopsy results available and were selected for further prevalence analysis. Results About 7.6% and 0.7% women with NILM/hrHPV+ had HSIL and AIS, respectively. The prevalence of HSIL+ squamous lesions is significantly higher in HPV-16+ group than that in other genotype groups (p < 0.0001). The prevalence of AIS+ glandular lesions is significantly higher in HPV-18/45+ groups than women in other genotype groups (p < 0.0001). In addition, the prevalence of HSIL+ lesions was significantly higher in age 25-39 years group than that in age 40-65 years group and >65 years group (p < 0.0001). Overall, the prevalence of HSIL+ in younger women was significantly higher than that in older women when using a cutoff age of 40 years (9.3% vs 5.9%, p < 0.0001) or 50 years (8.6% vs 4.9%, p < 0.0001). No significant difference in AIS+ prevalence was found among different age groups (p = 0.611). Interestingly, the prevalence of SCC and ADC in older women (≥40 years, 0.3% and 0.3%, respectively) was significantly higher than that in younger women (<40 years, 0% and 0.07%) (p = 0.001 for SCC; p = 0.02 for ADC). Conclusion The significant risk of cervical precancers and cancers still exists in women with NILM/hrHPV+, notably the older patient group had a lower risk of cervical precancer, but higher risk of cancer. Therefore, HPV genotyping can be an effective supplemental tool to cytology, and patient age also needs to be considered in the clinical management of patient.

Abstract
Human papilloma virus (HPV) is the primary causative agent of cervical, vaginal, and vulvar cancers. HPV E6/E7 mRNA detection has been proven to improve the specificity and positive predictive value compared with HPV DNA testing in screening, whereby, it may possess higher diagnostic potential. Herein, to establish the ultrasensitive and specific detection of HPV E6/E7 mRNA, we developed a novel triple signal amplification strategy, combined with gold nanoparticles (AuNPs), reverse transcription loop-mediated isothermal amplification (RT-LAMP) and high affinity biotin-avidin system. This novel proposed signal amplification strategy exhibits the desired detection limit of 0.08 fM (approximately 100 copies) and a wide linear range from 0.1 pmol/mL to 100 nmol/mL for HPV16 E6/E7 mRNA detection. Importantly, the present novel biosensor is 10-100 times more sensitive than conventional RT-PCR in detecting HPV16 E6/E7 mRNA positive clinical samples. Conclusively, this biosensor shows good stability, selectivity, and reproducibility, which demonstrates its potential in future clinical diagnosis with desirable sensitivity and specificity.

Abstract
INTRODUCTION Cervical cancer affects half a million women worldwide annually. Given the association between high-risk human papillomavirus (hrHPV) infection and carcinogenesis, hrHPV DNA testing became an essential diagnostic tool. However, hrHPV alone does not cause the disease, and, most importantly, many cervical lesions regress to normal in a year because of the host immune system. Hence, the low specificity of hrHPV DNA tests and their inability to predict the outcome of infections have triggered a further search for biomarkers. AREAS COVERED We evaluated the latest viral and cellular biomarkers validated for clinical use as primary screening or triage for cervical cancer and assessed their promise for prevention as well as potential use in the future. The literature search focused on effective biomarkers for different stages of the disease, aiming to determine their significance in predicting the outcome of hrHPV infections. EXPERT OPINION Biomarkers such as p16/Ki-67, hrHPV genotyping, hrHPV transcriptional status, and methylation patterns have demonstrated promising results. Their eventual implementation in the screening programs may support the prompt diagnosis of hrHPV infection and its progression to cancer. These biomarkers will help in making clinical management decisions on time, thus, saving the lives of hrHPV-infected women, particularly in developing countries.

Abstract
OBJECTIVE The Onco E6™ Cervical Test, based on detection of the E6 oncoprotein of HPV 16 and 18 genotypes is evaluated as a screen for the early detection cervical neoplasia in resource-limited countries. METHODS This prospective study from June 2018 to June 2019 evaluated 235 women aged 21-65 years, who came to Gynaecological Oncology Outpatient Department by VIA, cytology, E6 oncoprotein test and by colposcopy. Screen-positive women by any of the tests or women with suspicious findings were further evaluated by biopsy at colposcopy. The McNemar test was used to compare the performance of E6 oncoprotein test with other screening tests. RESULTS The E6 oncoprotein positivity rate was 6.8% (n = 16) with 81.25% HPV 16 positive and 18.75% HPV 18 positive. Among VIA positive cases (n = 100), E6 oncoprotein was positive in 9% (p < .001). In histopathology confirmed chronic cervicitis, CIN I, CIN II, CIN III and invasive cervical cancer, E6 test was positive for 2.8%, 4.7%, 25%, 50% and 100% respectively. E6 oncoprotein test had the highest specificity and Positive Predictive Value (PPV; 97% and 75%) compared to VIA (42% and 18%), cytology (95% and 46%) and colposcopy (94% and 59%). Sensitivity of the E6 oncoprotein test for detection of CIN3+ was significantly higher than that of cytology (52% VS 25%) but lower than that of VIA (52% VS 74%). CONCLUSIONS The HPV E6 oncoprotein test is highly specific and is an effective triage test to reduce colposcopy referrals for the large number of false positive test outcomes seen with VIA.

Abstract
Cervical cancer is a growing and serious problem world-wide in women, but more acute in developing countries especially in Indian subcontinent. The main causative agent for the disease is Human Papilloma Virus (HPV). The history of the cervical cancer goes back to eighteenth century as the HPV infection is reported since 1800s. Presently, the genetic structure of HPV is well defined. Several screening tests including cytology and visual based screening and high risk HPV testing are available. Also available are various clinical and commercial diagnostic tests. However due to the lack of awareness and population-based screening programs, the morbidity and mortality rate is alarmingly high. There are new emerging biomarkers including E6/E7 mRNA, p16ink4a, markers of aberrant S-phase induction, chromosomal abnormalities and miRNAs along with advanced genotyping methods. These markers have clinical significance and are helpful in disease prevention and management. Further, recent advancement in the field of metagenomics has increased the prospects of identifying newer microbes, viruses hitherto reported thus far in the context of HPV infection. Analysis of HPV cases using modern tools including genotyping using more powerful biomarkers is envisaged to enhance the prospects of early diagnosis, better prognosis, more reliable treatment and eventual management of the disease.

Abstract
Background Genital infection with certain types of Human papillomavirus (HPV) is a major cause of cervical cancer globally. For early detection of premalignant dysplasia, evidences are coming out on the usefulness of HPV E6/E7 mRNA test as a potential tool compared with cytology and HPV DNA testing. Taking into account shortage of compiled data on this field, the aim of this systematic review was to describe the latest diagnostic performance of HPV E6/E7 mRNA testing to detect high grade cervical lesions (CIN2+) where by histology was taken as a gold standard. Methods Articles published in English were systematically searched using key words from PubMed/Medline and SCOPUS. In addition, Google Scholar and the Google database were searched manually for grey literature. Two reviewers independently assessed study eligibility, risk of bias and extracted the data. We performed a descriptive presentation of the performance of E6/E7 mRNA test (in terms of sensitivity, specificity, negative and positive predictive values) for the detection of CIN2 + . Results Out of 231 applicable citations, we have included 29 articles that included a total of 23,576 study participants (age range, 15–84 years) who had different cervical pathologies. Among the participants who had cervical histology, the proportion of CIN2+ was between 10.6 and 90.6%. Using histology as a gold standard, 11 studies evaluated the PreTect HPV Proofer, 7 studies evaluated the APTIMA HPV assay (Gen-Probe) and 6 studies evaluated the Quantivirus® HPV assay. The diagnostic performance of these three most common mRNA testing tools to detect CIN2+ was; 1) PreTect Proofer; median sensitivity 83%, specificity 73%, PPV 70 and NPV 88.9%. 2) APTIMA assay; median sensitivity 91.4%, specificity 46.2%, PPV 34.3% and NPV 96.3%. 3) Quantivirus®: median sensitivity 86.1%, specificity 54.6%, PPV 54.3% and NPV was at 89.3%. Further, the area under the receiver operating characteristics (AU-ROC) curve varied between 63.8 and 90.9%. Conclusions The reported diagnostic accuracy implies that HPV mRNA based tests possess diagnostic relevance to detect CIN2+ and could potentially be considered in areas where there is no histology facility. Further studies including its cost should be considered.

Ren C, Zhu Y, Yang L, Zhang X, Liu L, Wang Z, Jiang D. Prognostic and diagnostic validity of p16/Ki-67, HPV E6/E7 mRNA, and HPV DNA in women with ASCUS: a follow-up study. Virol J 2019; 16:143. [PMID: 31752941 PMCID: PMC6873508 DOI: 10.1186/s12985-019-1251-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Accepted: 11/11/2019] [Indexed: 12/15/2022] Open
Abstract
Background We evaluated the prognostic and diagnostic ability of p16/Ki-67 immunocytochemistry, HPV E6/E7 mRNA testing and HPV DNA assay in triaging ASCUS to find a way to manage cervical lesions more effectively. Methods We conducted a prospective study through follow-up. The detection methods of the three factors: p16/Ki-67 immunocytochemistry conducted by using the CINtec® Plus Kit, E6/E7 mRNA testing by QuantiVirus®HPV E6/E7 mRNA assay and DNA by Hybrid Capture 2 assay. Results One hundred three women with ASCUS satisfied requirements and completed the entire follow-up process. All CIN2+ occurred in women who were mRNA positive at baseline, none in mRNA negative. 100% (6/6) patients with CIN2+ were HPV DNA assay positive, 100% (6/6) were HPV E6/E7 mRNA testing positive and 50.0% (3/6) were p16/Ki-67 immunocytochemistry positive. The risk ratio of E6/E7 mRNA test was 57.306 (95% CI 0.077–42,400.545). For endpoint of CIN2+, the sensitivity between HPV DNA assay and HPV E6/E7 mRNA testing is no statistical difference, but statistical difference exists between HPV E6/E7 mRNA testing vs. p16/Ki-67 immunocytochemistry (χ2 = 5.718, P = 0.023) and HPV DNA assay vs. p16/Ki-67 immunocytochemistry (χ2 = 5.718, P = 0.023). The specificity of E6/E7 mRNA testing, p16/Ki-67 and DNA assay in triaging ASCUS was 44.33, 75.26 and 11.34% respectively and is all statistical difference (χ2 = 26.277, P < 0.001(HPV DNA assay vs. HPV E6/E7 mRNA testing), χ2 = 19.297, P < 0.001(HPV E6/E7 mRNA testing vs. p16/Ki-67 immunocytochemistry), χ2 = 80.707, P < 0.001(HPV DNA assay vs. p16/Ki-67 immunocytochemistry). The expression level of 2097.09 copies/ml was the optimal cut-off value for HPV E6/E7 mRNA testing to diagnose CIN2+, the sensitivity and specificity was 61.1 and 68.2%. Conclusions High expression of HPV E6/E7 mRNA could be a good candidate as a diagnostic biomarker to triage ASCUS superseding HPV DNA. p16/Ki-67 immunocytochemistry is suggested to be a good tool to triage ASCUS, but it reduced the sensitivity of diagnosis when improves the diagnostic specificity.

Abstract
OBJECTIVE This systematic review evaluates the accuracy of the mRNA HPV biomarker in cervical smears to identify cervical intraepithelial neoplasia (CIN) 2 or 3 and cervical cancer. DATA SOURCE Eligible studies were identified by performing a search of electronic databases on Medline via Pubmed, Lilacs, Cochrane Library, Embase, and Grey literature for papers published between January 1990 and June 2018. STUDY ELIGIBILITY CRITERIA As no randomized studies were identified, this review focuses on observational studies in which the mRNA HPV diagnostic test was compared to a histopathology reference standard. We analyzed studies that included women screened for cervical cancer using mRNA HPV. STUDY APPRAISAL AND SYNTHESIS METHODS After screening, 61 studies including 29,674 patients met the inclusion criteria and were analyzed. Dichotomization was performed by defining CIN2 or worse (CIN2+) versus CIN1, HPV infection, and normal (CIN 1-). The analysis was discriminated by the following tests: Aptima, PreTect HPV Profeer, NucliSens EasyQ HPV, OncoTect, and Quantivirus. RESULTS Analyzing by technique, Aptima, with 28 studies, exhibited superior performance, showing for the outcomes CIN2+ and CIN3+ an AUC of 0.88 (0.82-0.95) and 0.91 (0.84-0.99), a pooled sensitivity of 92.8% (95%CI 91.9-93.7) and 95.6% (95%CI 94.5-96.5), and a pooled specificity of 60.5% (95%CI 59.8-61.3) and 61.9% (95%CI 61.1-62.7), respectively. CONCLUSION This study supports the current hypothesis that the mRNA HPV assay is an adequate tool for secondary cervical cancer screening.

Abstract
OBJECTIVES The main objective of this systematic review and meta-analysis is to specify the accuracy of messenger RNA human papillomavirus (HPV) tests among women with previous minor cervical lesion cytology to detect high-grade squamous intraepithelial lesions (CIN2+ and CIN3+) compared with a histopathological reference standard. The secondary objective is to compare messenger RNA HPV test accuracies and the DNA high-risk HPV test among these women. METHODS Eligible studies were identified by searching the electronic databases with medical subject headings. MAIN RESULTS Among the 2052 studies identified, 20 primary studies were included. Two tests were mainly identified: Aptima and PreTect HPV-Proofer. Aptima, with 10 studies, had better performance, considering atypical squamous cells of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion together, with a pooled sensitivity of 90.5% (95% confidence interval [CI], 88.1-92.6) and specificity of 55.1% (95% CI, 53.5-56.8) for CIN2+. For the ASC-US sample, Aptima had a pooled sensitivity of 90.1% (95% CI, 87.1-92.7) and specificity of 59.3% (95% CI, 57.5-61.1). CONCLUSIONS Messenger RNA HPV tests, mainly Aptima assay, can be recommended to triage women with ASC-US and low-grade squamous intraepithelial lesion because it has higher specificity with a small loss of sensitivity than Hybrid Capture 2 assay; this finding is promising as a means to reduce the overmanagement of minor cytological abnormalities.

Clinical performance of Anyplex II HPV28 by human papillomavirus type and viral load in a referral population. PLoS One 2019; 14:e0210997. [PMID: 30673759 PMCID: PMC6343909 DOI: 10.1371/journal.pone.0210997] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Accepted: 01/04/2019] [Indexed: 11/28/2022] Open
Abstract
Anyplex II HPV28 (`Anyplex`) is a semi-quantitative DNA PCR assay divided into set A, comprising 14 high risk (hr)HPV types; and set B, comprising 5 possibly hrHPV types and 9 low risk (lr)HPV types. We compared the ability of Anyplex to that of Hybrid Capture 2 (HC2) and PreTect HPV-Proofer (`Proofer`) to detect cervical intraepithelial neoplasia grade two or worse (CIN2+) by HPV types and viral load. This cross-sectional study included 296 women referred to colposcopy with abnormal cervical cytology and/or persistent HPV infection. CIN2+ was identified in 175/296 women. Liquid based cytology samples were used to perform HPV testing. The sensitivity of Anyplex to detect CIN2+ was 98.9% (95% CI 95.9–99.9) and specificity 43.0% (95% CI 34.0–52.3). Restricting to medium and high viral loads in Anyplex set A, sensitivity and specificity were 97.1% (95% CI 93.5–99.1) and 59.5% (95% CI 50.2–68.3) with positive (PPV) and negative predictive value (NPV) 77.6% and 93.5%, respectively, comparable to HC2. Restricting Anyplex to the hrHPV types in Proofer, HPV16, 18, 31, 33 and 45, sensitivity and specificity for CIN2+ were 85.1% (95% CI 79.0–90.1) and 71.1% (95% CI 62.1–79.0), comparable to Proofer`s. When adding HPV52 and 58, the sensitivity for CIN2+ was 92.6% (95% CI 87.6–96.0) and CIN3+ 96.5% (95% CI 92.0–98.8). No value of Anyplex set B was found in detecting CIN2+. In conclusion, the clinical performance of medium and high viral loads in Anyplex set A was comparable to HC2. Restricting the test to the 7 hrHPV types included in the 9-valent HPV-vaccine, HPV16, 18, 31, 33, 45, 52 and 58, satisfies the international criteria for cervical cancer screening with relative sensitivity compared to HC2 for CIN2+ and CIN3+ of 0.98 and 1.01, respectively. Detecting all 28 Anyplex HPV types adds no benefit in a referral population.

Abstract
Recent studies have demonstrated low specificity (false positive) of human papillomavirus (HPV) DNA testing for the screening and diagnosis of cervical samples. Therefore, we evaluated the performance of the HPV OncoCheck assay, which is an HPV E6/E7 mRNA-based assay, for the detection of 16 high-risk (HR)-HPVs including HPV 16 and HPV 18 genotypes in cervical samples using multiplex reverse transcriptase-quantitative PCR. In the present study, the analytical performance of the assay was evaluated using 16 HPV single strand DNAs. Clinical evaluation was performed using 319 Thinprep® liquid-based cytology samples obtained from women with cervical diseases, and the HPV OncoCheck assay results were compared with those of cytological diagnosis and sequence analysis. All 16 types of HPVs were detected with a minimum detection sensitivity of 100 copies per reaction and high specificity was observed. The sensitivity and specificity of the HPV OncoCheck assay for detecting high-grade lesions were 94.1% (95% confidence interval (CI), 0.875-0.975; p < .0001) and 95.4% (95% CI, 0.868-0.989; p < .0001), and sequence analysis were 99.4% (95% CI, 0.965-0.999; p < .0001), and 98% (95% CI, 0.939-0.996; p < .0001), respectively. Moreover, the agreement between the HPV OncoCheck assay and sequence analysis for the detection of HR-HPV was 98.8% (κ = 0.98, 95% CI 0.967-0.996; p < .0001). The results of this study showed high agreement and specificity with cytological diagnoses and sequence analysis. Future studies with histological follow- up are needed to determine whether use of the HPV OncoCheck assay in cervical screening may aid detection of the most significant cervical disease while reducing false-positive results.

Abstract
This chapter is the first one to introduce the detection of viral RNA splicing as a new tool for clinical diagnosis of virus infections. These include various infections caused by influenza viruses, human immunodeficiency viruses (HIV), human T-cell leukemia viruses (HTLV), Torque teno viruses (TTV), parvoviruses, adenoviruses, hepatitis B virus, polyomaviruses, herpesviruses, and papillomaviruses. Detection of viral RNA splicing for active viral gene expression in a clinical sample is a nucleic acid-based detection. The interpretation of the detected viral RNA splicing results is straightforward without concern for carry-over DNA contamination, because the spliced RNA is smaller than its corresponding DNA template. Although many methods can be used, a simple method to detect viral RNA splicing is reverse transcription-polymerase chain reaction (RT-PCR). In principle, the detection of spliced RNA transcripts by RT-PCR depends on amplicon selection and primer design. The most common approach is the amplification over the intron regions by a set of primers in flanking exons. A larger product than the predicted size of smaller, spliced RNA is in general an unspliced RNA or contaminating viral genomic DNA. A spliced mRNA always gives a smaller RT-PCR product than its unspliced RNA due to removal of intron sequences by RNA splicing. The contaminating viral DNA can be determined by a minus RT amplification (PCR). Alternatively, specific amplification of a spliced RNA can be obtained by using an exon-exon junction primer because the sequence at exon-exon junction is not present in the unspliced RNA nor in viral genomic DNA.

Abstract
OBJECTIVE Human papillomavirus (HPV) tests and genotyping (GT) have been used in clinical risk assessment. The purpose of this study was to analyze the performance of 2 common HPV testing platforms in risk evaluation for high-grade cervical lesions. MATERIALS AND METHODS Between January 1, 2015, and December 31, 2016, a total of 4,562 Pap tests with follow-up biopsies in our laboratory database were analyzed along with HPV tests performed on Cobas (CHPV, n = 3,959) or Aptima (AHPV, n = 603) platforms. RESULTS The sensitivity for biopsy-confirmed HSIL or worse lesions was 97% for both CHPV and AHPV (p = .75). AHPV showed significantly lower positive rates than CHPV in benign (56% vs 86%) or LSIL (66% vs 90%) biopsies, resulting in significantly higher specificity for HSIL or worse than CHPV (38% vs 12%, p < .001). AHPV demonstrated significantly higher positive predictive value for HSIL or worse (24% vs 16%, p < .001) and overall accuracy (48% vs 24%, p < .001) than CHPV. AHPV GT also had significantly higher specificity for biopsy-confirmed HSIL or worse than CHPV (88% vs 72%, p < .001) with comparable sensitivity (50% vs 51%, p = .75). Women with HPV 16 on AHPV were significantly more likely to have HSIL or worse on biopsies than those with HPV 16 on CHPV (likelihood ratio = 4.3 vs 2.0, p = .004). CONCLUSIONS Although both AHPV and CHPV were highly sensitive for biopsy-confirmed HSIL or worse lesions, AHPV and GT demonstrated significantly higher specificity and positive predictive value than CHPV. The difference is probably related to E6/E7 overexpression after viral DNA integration in high-grade lesions. The significantly higher specificity and overall accuracy of AHPV and GT for HSIL or worse lesions may be useful in clinical risk management.

Abstract
A few studies previously suggested that human papillomavirus (HPV) E6 messenger RNA (mRNA) may exist uniformly in all grades of cervical intraepithelial neoplasia (CIN), whereas the detection rate of E7 mRNA may increase with disease progression from low-grade CIN to invasive carcinoma. The aim of this study was to clarify the different roles of E6 and E7 mRNAs in cervical carcinogenesis. The presence of each E6 and E7 mRNA was analyzed in 171 patients with pathologically-diagnosed CIN or cervical carcinoma. We utilized a RT-PCR assay based on consensus primers which could detect E6 mRNA (full-length E6/E7 transcript) and E7 mRNAs (spliced E6*/E7 transcripts) separately for various HPV types. E7 mRNAs were detected in 6% of CIN1, 12% of CIN2, 24% of CIN3, and 54% of cervical carcinoma. The presence of E7 mRNAs was significantly associated with progression from low-grade CIN to invasive carcinoma in contrast with E6 mRNA or high-risk HPV (HR-HPV) DNA (p = 0.00011, 0.80 and 0.54). The presence of both E6 and E7 mRNAs was significantly associated with HPV16/18 DNA but not with HR-HPV DNA (p = 0.0079 and 0.21), while the presence of E6 mRNA was significantly associated with HR-HPV DNA but not with HPV16/18 DNA (p = 0.036 and 0.089). The presence of both E6 and E7 mRNAs showed high specificity and low sensitivity (100% and 19%) for detecting CIN2+ by contrast with the positivity for HR-HPV DNA showing low specificity and high sensitivity (19% and 89%). The positive predictive value for detecting CIN2+ was even higher by the presence of both E6 and E7 mRNAs than by the positivity for HR-HPV DNA (100% vs. 91%). In 31 patients followed up for CIN1-2, the presence of both E6 and E7 mRNAs showed significant association with the occurrence of upgraded abnormal cytology in contrast with E6 mRNA, HR-HPV DNA, or HPV16/18 DNA (p = 0.034, 0.73, 0.53, and 0.72). Our findings support previous studies according to which E7 mRNA is more closely involved in cervical carcinogenesis than E6 mRNA. Moreover, the separate analysis of E6 and E7 mRNAs may be more useful than HR-HPV DNA test for detecting CIN2+ precisely and predicting disease progression. Further accumulation of evidence is warranted to validate our findings.

Oncol Lett 2017; 14:6251-6258. [PMID: 29113275 DOI: 10.3892/ol.2017.6932] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2015] [Accepted: 03/14/2017] [Indexed: 12/14/2022] Open
Abstract
The present prospective study aimed to evaluate the effects of E6/E7 protein detection by western blotting on cervical cancer (CC) early screening compared with detection by Hybrid Capture 2 (HC2) test and ThinPrep cytological test (TCT) in a Chinese population. A total of 450 cases of cervical intraepithelial neoplasia (CIN) suspected samples (positive in ≥1 indicator of TCT and HC2 test) were recruited from women who were treated at the International Peace Maternity and Child Health Hospital (Shanghai, China) from March 2014 to February 2015. Each sample was analyzed by cytological test. In addition, human papillomavirus (HPV) DNA examination by Hybrid Capture Tube test and E6/E7 protein expression detection by western blotting were performed in all samples, as well as histologic diagnosis to determine the stage of CIN. The results revealed that, for the diagnosis of CIN2+, although the sensitivity of E6/E7 protein detection was lower than that of HC2 test (71.3 vs. 96.6%, respectively), the specificity was markedly improved (67.6 vs. 5.9%, respectively). Compared with that of TCT, the sensitivity of E6/E7 protein detection was much higher (36.2 vs. 71.3%, respectively), but the specificity was lower (88.2 vs. 67.6%, respectively). In the present study, HPV E6/E7 protein expression was evaluated as a potential new biomarker for CC, with satisfactory diagnostic values for HPV types 16 and 18. The relative diagnostic value may be further improved by combination of E6/E7 messenger RNA detection.

Abstract
Cervical cancer screening using Papanicolaou's smear test has been highly effective in reducing death from this disease. However, this test is unaffordable in low- and middle-income countries, and its complexity has limited wide-scale uptake. Alternative tests, such as visual inspection with acetic acid or Lugol's iodine and human papillomavirus DNA, are sub-optimal in terms of specificity and sensitivity, thus sensitive and affordable tests with high specificity for on-site reporting are needed. Using proteomics and bioinformatics, we have identified valosin-containing protein (VCP) as differentially expressed between normal specimens and those with cervical intra-epithelial neoplasia grade 2/3 (CIN2/CIN3+) or worse. VCP-specific immunohistochemical staining (validated by a point-of-care technology) provided sensitive (93%) and specific (88%) identification of CIN2/CIN3+ and may serve as a critical biomarker for cervical-cancer screening. Future efforts will focus on further refinements to enhance analytic sensitivity and specificity of our proposed test, as well as on prototype development.

Abstract
OBJECTIVE To compare E6/E7 mRNA and HPV DNA assays for evaluating women with atypical cells of undetermined significance (ASCUS). METHODS The present prospective study enrolled patients with ASCUS undergoing HPV testing at Third Affiliated Hospital of Zhengzhou University, China, between September 1, 2013, and January 31, 2016. Patients with positive HPV DNA test results underwent screening by E6/E7 mRNA assay, and the accuracy of HPV DNA and E6/E7 mRNA testing were compared, with histology used for definitive diagnoses. RESULTS In total, 591 patients with ASCUS underwent HPV DNA screening, with 455 and 136 having positive and negative results, respectively; 252 patients with positive results and 66 with negative results underwent biopsy and histology testing and were included in the study. The sensitivity of the E6/E7 mRNA assay was similar to that of HPV DNA testing (88.2%, 95% confidence interval [CI] 77.6-94.4 vs 90.7%, 95%CI 81.2-95.9; P=0.636) for the detection of cervical intraepithelial neoplasia grade 2+, and the specificity was higher (36.4%, 95%CI 29.6-43.9 vs 24.3%, 95%CI 19.1-30.3; P=0.006). The area under the receiver operating characteristic curve was greater for E6/E7 mRNA testing compared with HPV DNA testing (0.658 vs 0.588). CONCLUSION The higher specificity of the E6/E7 mRNA assay means it could be a promising technique in the management of women with ASCUS.

Human papillomavirus mRNA and DNA testing in women with atypical squamous cells of undetermined significance: A prospective cohort study. Int J Cancer 2016; 139:1839-50.

Abstract
In this prospective cohort study, we compared the performance of human papillomavirus (HPV) mRNA and DNA testing of women with atypical squamous cells of undetermined significance (ASC-US) during cervical cancer screening. Using a nationwide Danish pathology register, we identified women aged 30-65 years with ASC-US during 2005-2011 who were tested for HPV16/18/31/33/45 mRNA using PreTect HPV-Proofer (n = 3,226) or for high-risk HPV (hrHPV) DNA using Hybrid Capture 2 (HC2) (n = 9,405) or Linear Array HPV-Genotyping test (LA) (n = 1,533). Women with ≥1 subsequent examination in the register (n = 13,729) were followed for up to 9.5 years for high-grade cervical intraepithelial neoplasia (CIN) or cancer. After 3 years' follow-up, mRNA testing had higher specificity for CIN3 or worse (CIN3+) than HC2 testing (88.1% [95% confidence interval (CI): 86.8-89.6%] versus 59.3% [95% CI: 58.1-60.4%]) and higher positive predictive value (PPV) (38.2% [95% CI: 33.8%-43.1%] versus 19.5% [95% CI: 17.8-20.9%]). However, the sensitivity of mRNA testing was lower than that of HC2 testing (66.7% [95% CI: 59.3-74.5%] versus 97.0% [95% CI: 95.5-98.4%]), and women testing mRNA negative had higher 3-year risk for CIN3+ than those testing HC2 negative (3.2% [95% CI: 2.2-4.2%] versus 0.5% [95% CI: 0.3-0.7%]). Patterns were similar after 18 months and 5 years'; follow-up; for CIN2+ and cancer as outcomes; across all age groups; and when comparing mRNA testing to hrHPV DNA testing using LA. In conclusion, the HPV16/18/31/33/45 mRNA test is not optimal for ASC-US triage due to its low sensitivity and the substantial risk for precancer following a negative test.

Abstract
OBJECTIVES To assess the performance of a 5-type human papillomavirus (HPV) messenger RNA (mRNA) test in primary screening within the framework of the Norwegian population-based screening programme. DESIGN Nationwide register-based cohort study. SETTING In 2003-2004, general practitioners and gynaecologists recruited 18 852 women for participation in a primary screening study with a 5-type HPV mRNA test. PARTICIPANTS After excluding women with a history of abnormal smears and with cervical intraepithelial neoplasia grade 2 (CIN2+) before or until 3 months after screening, 11 220 women aged 25-69 years were eligible for study participation. The Norwegian Cancer Registry completed follow-up of CIN2+ through 31 December 2009. INTERVENTIONS Follow-up according to the algorithm for cytology outcomes in the population-based Norwegian Cervical Cancer Screening Programme. MAIN OUTCOME MEASURES We estimated cumulative incidence of CIN grade 3 or worse (CIN3+) 72 months after the 5-type HPV mRNA test. RESULTS 3.6% of the women were HPV mRNA-positive at baseline. The overall cumulative rate of CIN3+ was 1.3% (95% CI 1.1% to 1.5%) through 72 months of follow-up, 2.3% for women aged 25-33 years (n=3277) and 0.9% for women aged 34-69 years (n=7943). Cumulative CIN3+ rates by baseline status for HPV mRNA-positive and mRNA-negative women aged 25-33 years were 22.2% (95% CI 14.5% to 29.8%) and 0.9% (95% CI 0.4% to 1.4%), respectively, and 16.6% (95% CI 10.7% to 22.5%) and 0.5% (95% CI 0.4% to 0.7%), respectively, in women aged 34-69 years. CONCLUSIONS The present cumulative incidence of CIN3+ is similar to rates reported in screening studies via HPV DNA tests. Owing to differences in biological rationale and test characteristics, there is a trade-off between sensitivity and specificity that must be balanced when decisions on HPV tests in primary screening are taken. HPV mRNA testing may be used as primary screening for women aged 25-33 years and 34-69 years.

Abstract
Background Repeat cytology and HPV testing is used in triage of women with minor cytological lesions. The objective of this study was to evaluate 14-type HPV DNA and 5-type HPV mRNA testing in delayed triage of women with ASC-US/LSIL. Methods We compared a DNA test (Roche Cobas 4800) and an 5-type mRNA test (PreTect HPV-Proofer). In total 564 women were included in the study. Results The sensitivity among solved cases for CIN3+ were 100 % (15/15) for both tests. The sensitivity for CIN2+ of the HPV DNA test was 100 % (38/38) relative to 79 % (30/38) for the 5-type HPV mRNA test. The corresponding estimates of specificity for CIN2+ among solved cases were 84 % (393/466; 95 % CI: 81–88) and 91 % (451/498; 95 % CI: 88–93). The positive predictive values for CIN3+ were 13.5 % (15/111) for DNA+ and 19.5 % (15/77) for 5-type mRNA+. Significantly more women screened with 5-type mRNA than DNA returned to screening (81 % vs 71 %, p < 0.01). Subsequently, significantly fewer women were referred for colposcopy/biopsies/treatment (19 % (105/564) vs 29 % (165/564), p < 0.01). Conclusions 5-type HPV mRNA is more specific than 14-type HPV DNA in delayed triage of women with ASC-US/LSIL. The referral rate for colposcopy was 57 % higher for DNA+ relative to mRNA+ cases (165 vs 105), with the same detection rate of CIN3+, but the 5-type mRNA test had lower sensitivity for CIN2+. It is important to consider the trade-off between sensitivity and specificity of the diagnostic test when designing screening algorithms.

Abstract
The sensitivity of E6/E7 mRNA-based Aptima HPV test (AHPV; Hologic, Inc.) for detection of cervical cancer has been reported based on only a small number of cases. We determined the sensitivity of AHPV in comparison with the DNA-based Hybrid Capture 2 HPV test (HC2; Qiagen) for the detection of oncogenic HPV in a large number of cervical cancers at the time of diagnosis using cervical samples obtained in ThinPrep (Hologic). Samples yielding discordant results were genotyped using Linear Array assay (LA; Roche). Of 396 cases tested, AHPV detected 377 (sensitivity, 95.2%; 95%CI: 93.1-97.3), and HC2 376 (sensitivity, 94.9%; 95%CI: 92.7-97.1) with an agreement of 97.2% (kappa 0.7; 95%CI: 0.54-0.87). Among six AHPV+/HC2- cases, LA identified oncogenic HPV types in four including a type 73 and was negative in two. Among five AHPV-/HC2+ cases, LA detected oncogenic HPV types in two including a type 73 and was negative in three. Of 14 AHPV-/HC2- cases, 13 were genotyped. LA detected oncogenic HPV types in six, non-oncogenic types in three, and was negative in four. This is the largest study to demonstrate the sensitivity of AHPV for the detection of invasive cervical cancer and this assay showed equal sensitivity to HC2.

Abstract
This comprehensive review compiles published data from 62 original articles comparing different HPV tests and one meta-analysis on the clinical performance of the Aptima HR HPV (AHPV) assay in either screening or referral populations as well as for the purpose of test of cure. A number of publications with technical issues were also considered. Besides a brief introduction in the development of E6/E7 mRNA testing, the review summarizes data on analytical sensitivies and specificities, as well as on clinical sensitivity, specificity, NPV and PPV with histological endpoints CIN2+ and CIN3+, where available. Although most studies were of cross-sectional design, five studies with a longitudinal prospective design or component were identified. In addition to the study design, sample size, age and CIN2/3+ prevalence of the respective cohort are listed. This allows direct comparison of the published data in the respective groups. One major outcome of this review is the remarkably stable similar sensitivities of AHPV and HC2 independent from study design for detection of CIN2/3+ combined with a higher specificity of the AHPV. The second outcome was the longitudinal predictive value derived from registry linkage and other prospective studies that would support the applicability of the AHPV test in primary screening with at least a three year screening interval.

Abstract
HPV-16 L1 methylation and E6/E7 mRNA have suggested that they had close relationship with cervical neoplastic progression. This study aimed to evaluate the clinical performance of the HPV-16 L1 methylation assay and E6/E7 mRNA test for detecting high-grade cervical lesions (CIN2+). A total of 81 women with liquid-based cytology (LBC) samples, histological results, and positive HPV-DNA test for HPV type 16 only were included in this study. HPV-16 L1 methylation and E6/E7 mRNA levels were measured using methylation-sensitive high resolution melting (MS-HRM) analysis and Quantivirus®HPV E6/E7 RNA 3.0 assay (bDNA), respectively, in the same residue of LBC samples. The current date showed a positive correlation between the HPV-16 L1 methylation and the E6/E7 mRNA levels. The L1 methylation and mRNA levels both increased with disease severity. The mRNA test method showed higher sensitivity and NPV (98.0 and 91.7% vs. 89.8 and 80.8%), while lower specificity and PPV (34.4 and 69.6% vs. 65.6 and 80.0%), than the L1 methylation assay for detecting histology-confirmed CIN2+. When using the detection method of mRNA test combined with L1 methylation assay, we obtained a sensitivity of 89.8% and a specificity of 71.9%. These findings suggest that assessment of HPV-16 L1 methylation testing combined with E6/E7 mRNA testing may be a promising method for the triage of women with HPV type 16 only.

Abstract
Since the introduction of biomolecular testing for the identification of high-risk human papillomavirus DNA (hrHPV-DNA) in cervical cancer preventive strategies, many interesting aspects have emerged in this field; firstly, HPV-DNA testing has been demonstrated to have better sensitivity than conventional cytology in several settings: screening, triage of ASC-US and in follow-up after treatment. Despite this, some limitations of these new technologies have also been underlined: the major issue is the low specificity of the tests, which cannot discriminate between regressive and progressive infections. Thus, recent research has moved the attention towards novel markers of progression that could more precisely detect cases at real risk of cancer development. In view of the fact that progression to cancer is dependable of the E6/E7 proteins integration and transforming action, the overexpression of E6/E7 transcripts has been seen as a valuable marker of this risk. This review aims to summarise the literature data on this topic and to provide a clear view of the emerging perspectives.

HPV mRNA is more specific than HPV DNA in triage of women with minor cervical lesions. PLoS One 2014; 9:e112934.

Abstract
Background In Norway, repeat cytology and HPV testing comprise delayed triage of women with minor cytological lesions. The objective of this study was to evaluate HPV DNA and HPV mRNA testing in triage of women with an ASC-US/LSIL diagnosis. Materials and Methods We used repeat cytology, HPV DNA testing (Cobas 4800) and HPV mRNA testing (PreTect HPV-Proofer) to follow up 311 women aged 25–69 years with ASC-US/LSIL index cytology. Results Of 311 women scheduled for secondary screening, 30 women (9.6%) had ASC-H/HSIL cytology at triage and 281 women (90.4%) had ASC-US/LSIL or normal cytology. The HPV DNA test was positive in 92 (32.7%) of 281 instances, and 37 (13.2%) were mRNA positive. Of the 132 women with repeated ASC-US/LSIL, we received biopsies from 97.0% (65/67) of the DNA-positive and 92.9% (26/28) of the mRNA-positive cases. The positive predictive values for CIN2+ were 21.5% (14/65) for DNA positive and 34.6% (9/26) for mRNA positive (ns). The odds ratio for being referred to colposcopy in DNA-positive cases were 2.8 times (95% CI: 1.8–4.6) higher that of mRNA-positive cases. Compared to the mRNA test, the DNA test detected four more cases of CIN2 and one case of CIN3. Conclusions The higher positivity rate of the DNA test in triage leads to higher referral rate for colposcopy and biopsy, and subsequent additional follow-up of negative biopsies. By following mRNA-negative women who had ASC-US/LSIL at triage with cytology, the additional cases of CIN2+ gained in DNA screening can be discovered. Our study indicates that in triage of repeated ASC-US/LSIL, HPV mRNA testing is more specific and is more relevant in clinical use than an HPV DNA test.

Abstract
The complex interplay between HIV and human papillomavirus and its link to cervical dysplasia is poorly understood. This is the first study to assess the prevalence of oncogenic human papillomavirus mRNA in HIV-positive women, its relationship to HIV and its potential use in the triage of cervical cancer screening in HIV-positive women. In this cross-sectional study, we included 321 HIV-positive women. In all, 28.7% had abnormal cervical cytology, 51.1% were human papillomavirus DNA-positive and 21.8% tested positive for human papillomavirus mRNA. Women with a CD4 count of <200 × 10(6)/L were more likely to test positive for human papillomavirus DNA and mRNA. Virally suppressed women were less likely to be human papillomavirus DNA-positive; however, the same did not hold true for human papillomavirus mRNA. We found the human papillomavirus mRNA screening to be more specific when screening for low-grade squamous intraepithelial lesion and high-grade squamous intraepithelial lesion than human papillomavirus DNA at 84.53% compared to 57.36%. However, the sensitivity was less at 51.59% versus 91.07% for human papillomavirus DNA. It may be possible in the future to use human papillomavirus mRNA/DNA testing within a triage algorithm for the screening and management of cervical cancer in the HIV-positive patient.

Abstract
This study aims to evaluate the clinical performance of the NucliSENS EasyQ assay and compare it with HPV DNA genotyping for the detection of high-grade squamous intraepithelial lesions (HSIL) and cancer in a Korean population. In 188 total thin prep samples, the remaining fluid after cytology slide preparation was tested with Goodgene HPV DNA chips and the NucliSENS EasyQ HPV E6/E7 messenger RNA (mRNA) assay. The sensitivity and specificity of each test were calculated with HSIL and squamous cell carcinoma (SCC) as the disease endpoint. Out of the 188 samples, 139 (74%) were positive for DNA of 14 HPV types, while 57 (30%) cases were positive for E6/E7 mRNA. The DNA test was positive in cytology cases of SCC, HSIL, and atypical squamous cell. The mRNA test yielded results of 75%, 74%, 60%, 56%, and 29% positivity in abnormal cytology cases of SCC, HSIL, atypical squamous cells - cannot exclude HSIL, atypical squamous cells of undetermined significance, and low-grade squamous intraepithelial lesion, respectively. In normal cytology cases, the positivity rates were 9% and 53% for the mRNA and DNA tests, respectively. For detection of HSIL and SCC, the sensitivity of the mRNA test was 74.36% and that of the DNA test was 100%, while the specificities of the tests were 85% and 40.83%, respectively. These findings suggest that the HPV E6/E7 mRNA assay can overcome the shortcoming of low specificity of DNA assays for clinical detection of high-grade cervical lesions and malignancies.

Abstract
Persistent infection by high-risk human papillomavirus is a necessary cause for cervical cancer. DNA-based human papillomavirus (HPV) assays show high sensitivity but poor specificity in detecting high-grade cervical lesions. Assays detecting mRNA of the oncoproteins E6 and E7 show higher specificity but lack either detection of all high-risk genotypes or the ability to specify the detected genotypes. The aim of this study was to evaluate the clinical performance of the NucliSENS EasyQ HPV assay in comparison with the Hybrid Capture 2 test (HC2) and the CLART Human Papillomavirus 2 assay (CLART), using a clinical cut-off of cervical intraepithelial neoplasia grade 2 or worse. In the 554 studied women, the lowest HPV positivity rate was detected for NucliSENS EasyQ HPV assay (55.1%), while HC2 and CLART showed similar results (HC2: 77.4%; CLART: 78.0%). In comparison with the other tests, the NucliSENS EasyQ HPV assay showed a lower clinical sensitivity (79.3% vs. 96.4% for HC2 and 95.9% for CLART) but a higher clinical specificity (72.6% vs. 42.8% for HC2 and 42.5% for CLART). Detection of E6/E7 mRNA transcripts may provide a higher specificity for cervical intraepithelial neoplasia grade 2 lesions or worse, since the oncogenic potential of HPV infection depends on the over-expression of these two oncoproteins.

Abstract
The objective of the study was to evaluate prospectively the added value of E6/E7 mRNA detection in a stepwise protocol. A total of 1,422 samples were collected over a period of 17 months. The samples were referred for human papillomavirus (HPV) genotyping if they showed cytological evidence of atypical squamous cells of undetermined significance, low- or high-grade squamous intraepithelial lesion. If one or more of HPV types 16, 18, 31, 33, or 45 were present, mRNA was analyzed by the NucliSENS EasyQ HPV assay. The genotypical distribution of high-risk HPV was very heterogeneous; HPV 16, 18, 31, 33, and 45 represented 20.2%, 3.4%, 10.8%, 3.4%, and 3.8% of HPV-positive samples, respectively. Follow-up data were available for 35 patients. Although over the half (51.4%) of follow-up samples showing HPV DNA/mRNA consensus evolved to cervical intraepithelial neoplastic lesions, 25.7% showed no progression to neoplasia despite mRNA positivity. However, the major concern was the group (14.3%) that showed progression to cervical intraepithelial neoplasia despite mRNA negativity: all but one of these cases had a high-risk HPV genotype other than the five included in the NucliSENS EasyQ HPV assay. Markedly, 66.7% of the discordant samples between colposcopy and histology that underestimated the degree of cervical dysplasia were found in this group. Close monitoring of high-risk HPV DNA-positive/mRNA-negative cases remains necessary, which leads to questions about the added value of the evaluated protocol.

Abstract
Testing for high-risk types of alpha human papillomaviruses (HPV) is an invaluable part of clinical guidelines for cervical carcinoma screening, management and treatment. In this comprehensive inventory of commercial tests for detection of alpha-HPV, we identified at least 125 distinct HPV tests and at least 84 variants of the original tests. However, only a small subset of HPV tests has documented clinical performance for any of the standard HPV testing indications. For more than 75% of HPV tests currently on the market, no single publication in peer-reviewed literature can be identified. HPV tests that have not been validated and lack proof of reliability, reproducibility and accuracy should not be used in clinical management. Once incorporated in the lab, it is essential that the whole procedure of HPV testing is subject to continuous and rigorous quality assurance to avoid sub-optimal, potentially harmful practices. Manufacturers of HPV tests are urged to put more effort into evaluating their current and future products analytically, using international standards, and for clinical applications, using clinically validated endpoints. To assist with analytical validation, the World Health Organization is developing international standards for HPV types other than HPV16 and HPV18 and is planning development of external quality control panels specifically designed to be used for performance evaluation of current and future HPV tests. There is a need for more competitively priced HPV tests, especially for resource-poor countries, and uniform test validation criteria based on international standards should enable issuing more competitive and fair tender notices for purchasing. Automation systems allowing large-scale testing, as well as further increases in clinical performance, are the main needs in the further improvement of HPV tests. This article forms part of a special supplement entitled "Comprehensive Control of HPV Infections and Related Diseases" Vaccine Volume 30, Supplement 5, 2012.

Abstract
Current cervical cancer screening programs are changing due to the development of tests that detect the presence of human papillomavirus (HPV), the cause of cervical cancer. These tests are more sensitive than cytology-based methods for detecting cervical precancer and a negative test offers long-term assurance that cervical cancer will not develop and therefore longer screening intervals can be achieved. In screening programs, HPV-based tests have been approved to triage women with equivocal cytology results and as a primary testing method in conjunction with cytology. HPV-based tests also have a role in determining risk of recurrence after treatment for cervical precancer as well as in surveillance for vaccine-related changes in HPV genotype prevalence.

Abstract
Pap test, and especially HPV DNA test, identify a large group of women who do not have any clinically relevant lesions, i.e., CIN2+ (Cervical Intraepithelial Neoplasia grade 2 or worse), but who are at greater risk of getting lesions in the future. The follow up of these women needs new biomarkers with prognostic value. The objective of this study is to evaluate the prognostic value of E6/E7 mRNA over-expression assay (PreTect HPV-Proofer, Norchip) for 5 HR-HPV types (16, 18, 31, 33, and 45) for progression to CIN2+ after a negative colposcopy. This prospective study, conducted at four Italian centres, enrolled 673 women with either a negative colposcopy or a negative or CIN1 histology. The clinical end-point was histological confirmation of CIN2+. Women were classified at baseline according to mRNA results and managed according to local colposcopy protocols. At least one conclusive follow-up test was obtained for 347 women (25 months average lapse since recruitment, range 5–74). Only seven CIN2+ were detected during follow up, three among the 82 women positive for mRNA at baseline, two among the 250 negative (Fisher exact test, p = 0.02), and two among the 12 with an invalid test. Absolute CIN2+ risk was 6.7/1,000 person/years in the whole cohort. The absolute CIN2+ risk was 18.4/1,000 person/years and 3.6/1,000 person/years in mRNA-positive and mRNA-negative women, respectively. In conclusion, E6/E7 mRNA over-expression appears to be a good candidate as a prognostic biomarker to manage HR-HPV DNA-positive women with negative colposcopy or histology, particularly in order to decrease follow-up intensity in those who are negative.

Abstract
High-risk human papillomavirus (HR-HPV) genotype viral load and E6/E7 mRNA detection are proposed as surrogate markers of malignant cervical lesion progression. Currently, the use of commercially available DNA-based or mRNA-based tests is under investigation. In this study, the viral DNA load and E6/E7 mRNA detection of the five most common HR-HPV types detected in cervical cancer worldwide were compared in 308 cervical samples by using in-house type-specific quantitative real-time PCR assays and PreTect HPV-Proofer test, respectively. Sensitivity and negative predictive values were higher for the HPV-DNA assays combined (95.0% and 96.0%, respectively) than the RNA assays (77.0% and 88.0%, respectively); conversely, the mRNA test showed a higher specificity and higher positive predictive value (81.7% and 66.9%, respectively) than the DNA test (58.6% and 52.5%, respectively) for detecting histology-confirmed high-grade cervical intraepithelial neoplasia. A significantly higher association between viral DNA load and severity of disease was observed for HPV 16 and 31 (γ = 0.62 and γ = 0.40, respectively) than for the other HPV types screened. A good degree of association between the two assays was found for detection of HPV 16 (k = 0.83), HPV 18 (k = 0.72), HPV 33 (k = 0.66), and HPV 45 (k = 0.60) but not for HPV 31 (k = 0.24). Sequence analysis in L1 and E6-LCR regions of HPV 31 genotypes showed a high level of intra-type variation. HR-HPV viral DNA load was significantly higher in E6/E7 mRNA positive than negative samples (P < 0.001), except for HPV 31. These findings suggest that transcriptional and replicative activities can coexist within the same sample.

Abstract
Human papillomavirus (HPV) infection is associated with a wide spectrum of disease that ranges from self-limited skin warts to life-threatening cancers. Since HPV plays a necessary etiological role in cervical cancer, it is logical to use HPV as a marker for early detection of cervical cancer and precancer. Recent advances in technology enable the development of high-throughput HPV assays of different formats, including DNA-based, mRNA-based, high-risk group-specific and type-specific methods. The ultimate goal of these assays is to improve the accuracy and cost-effectiveness of cervical screening programs. HPV testing has several potential advantages compared to cytology-based screening. However, since the cancer to transient infection ratio is always low in the general population, HPV test results are bound to have a low positive predictive value that may subject women to unnecessary follow-up investigations. The wide-spread administration of prophylactic HPV vaccine will substantially decrease the incidence of cancer and precancer. This poses a number of challenges to cytology-based screening, and the role of HPV testing is expected to increase. Finally, apart from technical and cost-effectiveness considerations, one should also keep in mind the psycho-social impact of using sexually-transmitted agents as a marker for cancer screening.

Abstract
Recent technical advances have begun to realize the potential of molecular beacons to test for diverse infections in clinical diagnostic laboratories. These include the ability to test for, and quantify, multiple pathogens in the same clinical sample, and to detect antibiotic resistant strains within hours. The design principles of molecular beacons have also spawned a variety of allied technologies.

High-risk human papillomavirus (hrHPV) E6/E7 mRNA testing by PreTect HPV-Proofer for detection of cervical high-grade intraepithelial neoplasia and cancer among hrHPV DNA-positive women with normal cytology.

Abstract
Our aim was to investigate whether high-risk HPV (hrHPV) mRNA detection by PreTect HPV-Proofer can be used to stratify hrHPV DNA-positive women of different cytology classes for risk of high-grade cervical intraepithelial neoplasia or worse (cervical precancer or cancer, i.e., cervical intraepithelial neoplasia grade 2 or higher [≥ CIN2]). A total of 375 women participating in population-based screening, with a GP5+/6+-PCR hrHPV DNA-positive cervical scrape with normal cytology (n = 202), borderline or mild dyskaryosis (BMD) (n = 88), or moderate dyskaryosis or worse (>BMD) (n = 85), were enrolled. Cervical scrapes were additionally subjected to HPV16/18/31/33/45 E6/E7 mRNA analysis by PreTect HPV-Proofer (mRNA test). Referral and follow-up policies were based on cytology, hrHPV DNA, and mRNA testing. The primary study endpoint was the number of ≥CIN2 detected within 3 years of follow-up. The mRNA positivity increased with the severity of cytological abnormality, ranging from 32% (64/202) in hrHPV DNA-positive women with normal cytology to 47% (41/88) in BMD and 68% (58/85) in >BMD groups (P < 0.01). Women with ≥ CIN2 were more likely to test positive by mRNA test (63%) than women without evidence of ≥ CIN2 (32%; P < 0.01). A positive mRNA test result conferred an increased ≥ CIN2 risk in hrHPV DNA-positive women with normal cytology, i.e., 0.55 (95% confidence interval [95% CI], 0.34 to 0.76) in mRNA-positive versus 0.20 (95% CI, 0.07 to 0.33) in mRNA-negative women. In hrHPV DNA-positive women with BMD or >BMD, the result of the mRNA test did not influence the ≥ CIN2 risk. In conclusion, mRNA testing by PreTect HPV-Proofer might be of value to select hrHPV DNA-positive women with normal cytology in need of immediate referral for colposcopy.

Abstract
Infection with high-risk (HR) human papillomavirus (HPV) genotypes is an important risk factor for cervical cancers. We evaluated the clinical performances of two new real-time PCR assays for detecting HR HPVs compared to that of the Hybrid Capture 2 test (HC2). A total of 356 cervical swab specimens, which had been examined for cervical cytology, were assayed by Abbott RealTime HR and Roche Cobas HPV as well as HC2. Sensitivities and specificities of these assays were determined based on the criteria that concordant results among the three assays were regarded as true-positive or -negative and that the results of genotyping and sequencing were considered true findings when the HPV assays presented discrepant results. The overall concordance rate among the results for the three assays was 82.6%, and RealTime HR and Cobas HPV assays agreed with HC2 in 86.1% and 89.9% of cases, respectively. The two real-time PCR assays agreed with each other for 89.6% of the samples, and the concordance rate between them was equal to or greater than 98.0% for detecting HPV type 16 or 18. HC2 demonstrated a sensitivity of 96.6% with a specificity of 89.1% for detecting HR HPVs, while RealTime HR presented a sensitivity of 78.3% with a specificity of 99.2%. The sensitivity and specificity of Cobas HPV for detecting HR HPVs were 91.7% and 97.0%. The new real-time PCR assays exhibited lower sensitivities for detecting HR HPVs than that of HC2. Nevertheless, the newly introduced assays have an advantage of simultaneously identifying HPV types 16 and 18 from clinical samples.
