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.

Human papillomavirus negative high grade cervical lesions and cancers: Suggested guidance for HPV testing quality assurance. J Clin Virol 2024; 171:105657. [PMID: 38401369 DOI: 10.1016/j.jcv.2024.105657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 02/12/2024] [Accepted: 02/19/2024] [Indexed: 02/26/2024]
Abstract
BACKGROUND Some high-grade cervical lesions and cervical cancers (HSIL+) test negative for human papillomavirus (HPV). The HPV-negative fraction varies between 0.03 % and 15 % between different laboratories. Monitoring and extended re-analysis of HPV-negative HSIL+ could thus be helpful to monitor performance of HPV testing services. We aimed to a) provide a real-life example of a quality assurance (QA) program based on re-analysis of HPV-negative HSIL+ and b) develop international guidance for QA of HPV testing services based on standardized identification of apparently HPV-negative HSIL+ and extended re-analysis, either by the primary laboratory or by a national HPV reference laboratory (NRL). METHODS There were 116 initially HPV-negative cervical specimens (31 histopathology specimens and 85 liquid-based cytology samples) sent to the Swedish HPV Reference Laboratory for re-testing. Based on the results, an international QA guidance was developed through an iterative consensus process. RESULT Standard PCR testing detected HPV in 55.2 % (64/116) of initially "HPV-negative" samples. Whole genome sequencing of PCR-negative samples identified HPV in an additional 7 samples (overall 61.2 % HPV positivity). Reasons for failure to detect HPV in an HSIL+ lesion are listed and guidance to identify cases for extended re-testing, including which information should be included when referring samples to an NRL are presented. CONCLUSION Monitoring the proportion of and reasons for failure to detect HPV in HSIL+ will help support high performance and quality improvement of HPV testing services. We encourage implementation of QA strategies based on re-analysis of "HPV negative" HSIL+ samples.

Enhancing Cervical Cancer Prevention in South African Women: Primary HPV mRNA Screening with Different Genotype Combinations. Cancers (Basel) 2023; 15:5453. [PMID: 38001713 PMCID: PMC10670851 DOI: 10.3390/cancers15225453] [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: 10/26/2023] [Revised: 11/13/2023] [Accepted: 11/14/2023] [Indexed: 11/26/2023] Open
Abstract
BACKGROUND Cervical cancer prevention in regions with limited access to screening and HPV vaccination necessitates innovative approaches. This study explored the potential of a test-and-treat strategy using mRNA HPV tests to impact cervical cancer prevention in a high-prevalence HIV population. METHODS A cervical screening study was conducted at three South African hospitals involving 710 under-screened, non-pregnant women (25 to 65 years) without known cervical diseases. Cytology, HPV testing, colposcopy, and biopsies were performed concurrently. Histopathologists determined final histological diagnoses based on biopsy and LLETZ histology. mRNA-HPV-genotyping for 3 (16, 18, 45) to 8 (16, 18, 31, 33, 35, 45, 52, 58) high-risk types was performed on leftover liquid-based cytology material. The preventive potential of the test-and-treat approach was estimated based on published data, reporting the causative HPV types in cervical cancer tissue from South African women. Treatment was provided as needed. RESULTS The HPV positivity rate more than doubled from 3-type (15.2%; 95% CI: 12.6-17.8) to 8-type mRNA (31.5%; 95% CI: 28.8-34.9) combinations, significantly higher among HIV-positive women. CIN3+ prevalence among HIV-positive women (26.4%) was double that of HIV-negative women (12.9%) (p < 0.01). The 6-type combination showed the best balance of sensitivity, specificity and treatment group size, and effectiveness to prevent cervical cancer. A 4-type combination (16, 18, 35, 45) could potentially prevent 77.6% (95% CI: 71.2-84.0) of cervical cancer burden by treating 20% and detecting 41.1% of CIN3 cases in the study group. Similarly, a 6-type combination (16, 18, 31, 33, 35, 45), treating 25% and including 62% of CIN3 cases, might prevent 85% of cervical cancer cases (95% CI: 79.6-90.6) among HIV-positive and negative women. CONCLUSION Employing mRNA HPV tests within a test-and-treat approach holds huge promise for targeted cervical cancer prevention in under-screened populations. Testing for mRNA of the 6 highest-risk HPV types in this population and treating them all is projected to effectively prevent progression from CIN3 to invasive cervical cancer while reducing overtreatment in resource-constrained settings.

Overexpression of E6/E7 mRNA HPV Is a Prognostic Biomarker for Residual Disease Progression in Women Undergoing LEEP for Cervical Intraepithelial Neoplasia 3. Cancers (Basel) 2023; 15:4203. [PMID: 37686479 PMCID: PMC10487243 DOI: 10.3390/cancers15174203] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 08/11/2023] [Accepted: 08/18/2023] [Indexed: 09/10/2023] Open
Abstract
The risk of overtreatment or not treating an occult carcinoma exists in women at risk of residual disease after a LEEP excision for CIN3. Our goal was to discover an efficient method to select patients requiring a second LEEP from those requiring a FU only through an mRNA-detection test. In a population of 686 women undergoing a LEEP excision for CIN 3, we selected 285 women at risk of residual disease and subjected them to a search for E6/E7 mRNA HPV. The women with negative mRNA were subjected to a follow up, while the women with positive mRNA were subjected to a second LEEP. The histological examination of the second cone revealed 120 (85.7%) cases of residual disease in the mRNA-positive women: 40 cases of CIN2, 51 cases of CIN3, 11 cases of squamous microinvasive carcinoma, 7 cases of squamous carcinoma, 9 cases of AIS (adenocarcinoma in situ) and 2 cases of adenocarcinoma. Among the mRNA-negative women undergoing a follow up, there were only five cases of residual disease. During the follow-up period of about 6 years, we witnessed the regression of the residual disease and the elimination of the virus, just as predicted by the negative result of the mRNA test. Testing patients for E6/E7 mRNA allowed us to identify women with residual disease (CIN2+) and treat them appropriately.

Abstract
BACKGROUND The study's purpose was to evaluate the performance of a five-type HPV mRNA test to predict cervical intraepithelial neoplasia grade 3 or worse (CIN3+) during up to 12 years of follow-up. METHODS Overall, 19,153 women were recruited by gynecologists and general practitioners in different parts of Norway between 2003 and 2004. The study population comprised 9582 women of these women, aged 25-69 years with normal cytology and a valid five-type HPV mRNA test at baseline. Follow-up for CIN3+ through 2015 was conducted in the Norwegian Cervical Cancer Screening Programme. RESULTS The cumulative incidence of CIN3+ by baseline status for HPV mRNA-positive and mRNA-negative women were 20.8% and 1.1%, respectively (p < 0.001). Age did not affect the long-term ability of the HPV mRNA test to predict CIN3+ during follow-up. CONCLUSION The low long-term risk of CIN3+ among HPV mRNA-negative women and the high long-term risk among HPV mRNA-positive women strengthen the evidence that the five-type HPV mRNA test is an appropriate screening test for women of all ages. Our findings suggest that women with a negative result may extend the screening interval up to 10 years.

Abstract
Background: A plethora of data supports HPV-based screening to be the preferred strategy for cervical cancer prevention. The shift to a more sensitive first-line test brings the need of effective triage up for discussion. Currently, most algorithms apply cytology as a triage of HPV-DNA positive women. This study compared the performance of a 7-type HPV-mRNA test to cytology. Methods: From 1 January 2019 until 31 December 2021, cervical samples from 58,029 women were examined at the University Hospital of North Norway. A total of 30.5% (17,684/58,029) fulfilled the criteria for HPV-DNA primary screening. All positive samples were triaged by cytology and followed-up according to national guidelines through 2022. Additionally, a 7-type HPV-mRNA test was applied. The study endpoint was a histologically confirmed high-grade lesion (CIN2+). Results: A total of 5.6% (990/17,684) had positive HPV-DNA test, 97.2% (962/990) with valid HPV-mRNA results. A total of 55.5% (534/962) had abnormal cytology (ASC-US+), and 35.1% (338/962) had a positive HPV-mRNA test. A total of 13.9% (134/962) had CIN2+. The sensitivity (CIN2+) of cytology versus the HPV-mRNA test was 76.1% (102/134) versus 73.1% (98/134), p = 0.67. The specificity was 47.8% (396/828) versus 71.0% (588/624), p < 0.001. PPV was 19.1% (102/534) and 29.0% (98/338), p < 0.001, respectively. The number of colposcopies per CIN2+ detected by cytology and HPV-mRNA test was 5.2 and 3.1. Conclusion: The 7-type HPV mRNA test was significantly more specific than cervical cytology in a triage of HPV-DNA positive women. Using this biomarker as the threshold for colposcopy may better balance the benefits and harms of screening.

Abstract
BACKGROUND A specific, cost-effective triage test for minor cytological abnormalities is essential for cervical cancer screening among younger women to reduce overmanagement and unnecessary healthcare utilization. We compared the triage performance of one 13-type human papillomavirus (HPV) DNA test and one 5-type HPV mRNA test. METHODS We included 4115 women aged 25-33 years with a screening result of atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSIL) recorded in the Norwegian Cancer Registry during 2005-2010. According to Norwegian guidelines, these women went to triage (HPV testing and repeat cytology: 2556 were tested with the Hybrid Capture 2 HPV DNA test, which detects the HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68; and 1559 were tested with the PreTect HPV-Proofer HPV mRNA test, which detects HPV types 16, 18, 31, 33, and 45). Women were followed through December 2013. RESULTS HPV positivity rates at triage were 52.8% and 23.3% among DNA- and mRNA-tested women (p < 0.001), respectively. Referral rates for colposcopy and biopsy and repeat testing (HPV + cytology) after triage were significantly higher among DNA-tested (24.9% and 27.9%) compared to mRNA-tested women (18.3% and 5.1%), as were cervical intraepithelial neoplasia grade 3 or worse (CIN3+) detection rates (13.1% vs. 8.3%; p < 0.001). Ten cancer cases were diagnosed during follow-up; eight were in DNA-tested women. CONCLUSION We observed significantly higher referral rates and CIN3+ detection rates in young women with ASC-US/LSIL when the HPV DNA test was used at triage. The mRNA test was as functional in cancer prevention, with considerably less healthcare utilization.

Abstract
BACKGROUND Despite a well-established cervical cancer (CC) screening program in Norway, the incidence of CC in young women is increasing, peaking at 35 years of age. 25 percent of all women diagnosed with CC had normal cytology within 3 years prior to cancer diagnosis, addressing the need to improve the screening programme to further reduce cancer incidences missed by cytology. OBJECTIVE We wanted to investigate the detection rate of CIN3+ in women 25-39 years with normal cytology by using a 3-type HPV mRNA test as a targeted quality assurance measure. The control group is women with normal cytology. METHODS During 2014-2017, samples from 13,021 women 25-39 years of age attending cervical cancer screening were analysed at Nordlandssykehuset, Bodø, Norway, including 1,896 women with normal cytology and HPV mRNA test (intervention group), and 11,125 women with cytology only (control group). The HPV mRNA testing was performed using a 3-type HPV E6/E7 mRNA test (PreTect SEE; direct genotyping 16, 18 and 45). The women were followed-up according to national guidelines throughout December 2021. RESULTS Of the 13,021 women, 429 women (3.3%) had CIN3+ confirmed by biopsy in the follow-up, including 13 cases of invasive cervical cancer. Of the 1,896 women with normal cytology and HPV mRNA test (intervention group), 49 women (2.6%) had a positive test. The risks of CIN3+ among women with either a positive or negative HPV mRNA test were 28.6% (14/49) and 0.8% (14/1847). None of the women in the intervention group developed cervical cancer during follow-up. Of the 11,125 women with cytology only (control group), 712 women (6.4%) had abnormal cytology (ASC-US+). The risks of CIN3+ among women with abnormal and normal cytology were 17.7% (126/712) and 2.6% (275/10,413). CONCLUSION By testing women 25-39 years of age with a normal cytology result using a specific 3-type HPV mRNA test, an increase in screening programme sensitivity can be achieved without an excessive additional workload. Women with normal cytology and a negative HPV mRNA test have a very low risk of cervical cancer.

Abstract
OBJECTIVES To evaluate the incidence of HPV infection, and the frequency of the various genotypes, using mRNA and DNA testing; to assess their relationship with the cervical lesions and women's age in the Polish patients. STUDY DESIGN A group of 1840 women, most of whom had abnormal cytology, from the Franciszek Łukaszczyk Oncology Centre in Bydgoszcz, Poland were screened for presence of at least one of 13 high risk HPV. Following that, 545 HPV DNA positive women were tested for HPV infection using HPV mRNA with the Nucleic Acid Sequence-Based Amplification Assay (NASBA) method. RESULTS In our study group, 70.1% had DNA HPV positive results. Only 4% of the women had normal cytology. Among 545 HPV DNA positive patients, 36.3% had HPV mRNA positive tests. Moreover, 48% of the HPV mRNA positive patients were infected with HPV 16, followed by 18 (12.6%), 31 (10.1%), 33 (8.6%%), 45 (4.5%), and 16.2% of HPV mRNA positive women were infected with more than one HPV genotype. Furthermore, we found that in women under 30, HPV DNA positivity was higher than HPV mRNA positivity, supporting the hypothesis that younger women's infections are mostly temporary. CONCLUSIONS The differences in HPV prevalence and genotype distribution observed in our study may have an impact on the efficacy of HPV vaccinations for cervical cancer and the development of screening programs, which should be examined further in future studies.

Self-collected versus clinician-collected cervical samples for the detection of HPV infections by 14-type DNA and 7-type mRNA tests. BMC Infect Dis 2021; 21:504. [PMID: 34058992 PMCID: PMC8165795 DOI: 10.1186/s12879-021-06189-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 05/16/2021] [Indexed: 11/17/2022] Open
Abstract
Background HPV self-sampling has been widely supported by the scientific community following a strong body of literature on the subject. Self-sampling is important in cervical cancer screening as it has been shown to improve participation. It is well documented that HPV-testing has proven superior to cytology with regards to sensitivity in detection of CIN and cancer. The value of self-collected samples is reliant on the quality of the molecular testing performed, as well as the patients’ preference in sampling procedure and compliance to follow up on positive test results. Due to the incompatibility of self-samples and cytology, triage of HPV-DNA positives by testing for molecular biomarkers is highly warranted. Methods Our objective was to compare the detection rate of genital Human Papillomavirus (HPV) infection in self- and clinician-collected samples by a 14-type HPV-DNA test and a 7-type mRNA E6/E7 test. Results Five hundred five women were recruited. Each study participant had two sample collection procedures performed upon the same visit, alternating order in execution of the self-collection or the clinician-taken procedure first or second, 1010 samples in total. HPV-DNA prevalence was 22.8% in self-collected versus 19.2% in clinician-collected samples (P = 0.19). Overexpression of mRNA E6/E7 from 7 HPV types was 7.1 and 6.3%, respectively (P = 0.71). The difference between HPV-DNA and HPV-mRNA positivity rates were statistically significant in both self-collected (22.8% versus 7.1%, P < 0.001) and clinician-collected samples (19.2% versus 6.3%, P < 0.001). Overall agreement between the two collection methods was fair, with a concordance rate of 78.2% (390/505), k = 0.34 (95% CI: 0.25–0.44), P < 0.001, for the HPV-DNA test and 92.5% (467/505), k = 0.40 (95% CI, 0.25–0.56), P < 0.001, for the mRNA test, respectively. 96.8% of the participants reported they felt confident carrying out the self-collection themselves, and 88.8% reported no discomfort at all performing the procedure. Conclusions This comparative study of two sampling methods reports fair agreement of HPV positivity rates between the self-collected and clinician-collected specimens using Abbott hrHPV and PreTect HPV-Proofer’7 tests. Only one third of HPV-DNA positive women had overexpression of mRNA E6/E7. Trial registration ISRCTN77337300.

Abstract
OBJECTIVE Cytology findings of atypical squamous cells of unknown significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL) are common among women under 30, but evidence on best management strategy is insufficient. We therefore investigated how different management strategies used in Denmark influenced biopsy rates and detection of cervical intraepithelial neoplasia (CIN). METHODS Register-based cohort study including Danish women aged less than 30 years and born 1980-95, with ASCUS/LSIL as their first abnormal cervical cytology in 2008-16. Rates and relative risks (RR) of biopsy and detection of CIN3+, CIN2 and < CIN2 during two years follow-up were compared between women referred directly to colposcopy after ASCUS/LSIL or undergoing additional testing, including mRNA or DNA test for high risk HPV or repeat cytology. RESULTS 19,946 women with ASCUS and 19,825 with LSIL were included in the study of whom 92% had adequate information about follow-up. Among women referred directly to biopsy, CIN3+ was detected among 21%, CIN2 in 17%, while 62% had < CIN2. Repeating cytology after 6 months reduced the biopsy rate to 44% of which 53% had < CIN2. Biopsy rates with HPV test were 67% for DNA test, 77% with 14-type mRNA test and 58% with 5-type mRNA test. The detection of CIN3+ was somewhat higher, between 13% and 14% for the three HPV tests vs. 11% with repeat cytology. However, the detection of < CIN2 (not indicating treatment) also increased with RR 2.11 (95% CI 2.01-2.21) for 14-type mRNA test, 1.35 (95% CI 1.29-1.41) for 5-type mRNA test, and 1.86 (95% CI 1.76-1.97) with HPV DNA test. CONCLUSIONS The choice of management strategy influences both the detection rate for severe lesions (CIN3+) and the proportion of women followed up for potentially insignificant findings.

Abstract
Background Clinical management of HPV positive women is difficult since many of the infections, including high-risk oncogene genotypes (hr-HPV), are transient. Therefore only a limited number of patients have a high-grade lesion and sending all HPV positive women for colposcopy would only increase costs and unnecessary treatment, with serious psychological consequences for patients. The need has emerged to identify other HPV related markers able to correctly detect women with a high-risk of developing high-grade lesions. Genotyping and the search for E6/E7 mRNA are among the possible candidates. Methods The study was carried out by means of an observational analysis of the data relative to 674 HR-HPV positive women who we had observed from January 2013 to June 2015; the data had been gathered in a database at the HPV Center of the University Hospital of Catania, Italy. Women were considered eligible for this study if the following data was present in the database: Pap TEST, histologic evaluation, HPV TEST and E6/E7 mRNA detection. We calculated the Odds Ratio (OR) of woman who were mRNA positive, with CIN2+ lesions, and Odds Ratio of HPV16 positive women. Results Transcripts were detected in 23.6% (69/292) of the women with CIN1 and in 97.2% (210/220) of those with CIN2 + . Regarding genotyping, the 81,8% (180/220) of the women with CIN2+ had genotype 16, while only 18.1% (40/220) had genotype 18, 31, 33, 45. We calculated the OR in the group of HPV16 women with CIN2+ (OR = 4.62; 95% CI = 3.13 to 6.82), this value increased (OR = 106.12; 95% CI = 53.71 to 209.69) in women with CIN2+ and positive mRNA. Discussion The presence of the HPV16 genotype in our study was associated with a risk 5 times greater of developing a high-grade lesion (CIN2+) (OR = 4.62 95% CI:3.13–6.82); this supports the hypothesis that it would be opportune to have targeted protocols for the management of HPV 16 positive women. The results showed that there was an association between E6/E7 mRNA expression and histology (OR = 106.12; 95% CI = 53.71 to 209.69). The E6/E7 mRNA test showed a higher prevalence of E6 and E7 transcripts in patients with higher-grade lesions. Conclusion The results of this study suggest that the HPV genotype determination and E6/E7 mRNA detection would find an important application for management of HPV positive women.

Abstract
BACKGROUND The aims of this study were to detect HPV E6/E7 mRNA expression in women with high-risk genotypes (HPV-16, -18, -31, -33 and -45) analysing its relationship with tissue pathology and 2) 2-year follow-up of E6/E7 mRNA tested group. METHODS Our samples were genotyped and classified by pathologists according to Bethesda system. After RNA extraction, E6/E7 oncogene mRNA detection was performed by NucliSens® EasyQ® HPV v1 Test (bioMérieux). RESULTS The results of the present study showed that E6/E7 mRNA positivity rate was 68.29 % in women tested once and 69.56 % in women tested twice. According to tissue pathology, all samples with high-grade lesions were positive for mRNA. Among women with low-grade lesions varied over the years from 89.28 to 84 % in women tested once and from 77.77 to 70 % in tested twice. Among women without lesion, positivity rate maintained in women tested once (from 50 to 41.38 %) and decreased in tested twice, from 63.63 to 44.44 %. Regarding lesion evolution, mRNA positivity was higher in women with lesion progression (53.13 %) and in women with positive results in two tested samples (83.33 %). CONCLUSION HPV E6/E7 mRNA detection may be an effective screening test and biomarker for cervical cancer in women infected with these five genotypes. Nonetheless, further studies are needed to standardize as routine triage test.

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
AIMS AND OBJECTIVES To study the colposcopic findings and prevalence of lower genital tract infections in HIV-positive women on anti-retroviral therapy. To find correlation between colposcopic finding, m RNA HPV and cytology of lower genital tract infections in HIV-positive women on anti-retroviral therapy. MATERIALS AND METHODS The present prospective observational study was conducted in the Department of Obstetrics and Gynaecology, Netaji Subhash Chandra Bose Medical College, Jabalpur, from 1 June 2013 to 31 October 2014. The data of the present study was recorded into computer and after proper validation, error checking, coding and decoding, the data was compiled and analysed using the SPSS Windows. Appropriate univariate and bivariate analysis were carried out using the Student's t test and two-tailed Fisher exact test or Chi-square test for categorical variables. RESULTS AND CONCLUSION The present study concludes that the prevalence of lower genital tract infections is 25.3 % in HIV-positive women on anti-retroviral therapy. It revealed that 35 HIV-positive women on anti-retroviral therapy who were screened for m HPV RNA test, one came out to be positive (i.e. 2.8 %); thus, it can be said that there is an increased clearance of oncogenic HPV types in HIV-positive women on anti-retroviral therapy.

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
Cancer imposes a heavy societal burden worldwide, in terms of both epidemiology and costs. The introduction of more sophisticated imaging and diagnostic techniques and advanced drugs that specifically target tumor cells is leading to increasingly expensive treatments, which may be affordable only for few patients. Prevention, and particularly primary prevention, is an effective way of addressing the challenging issue of cancer, since between a third and a half of cancers could be prevented on the basis of our current knowledge of risk factors. Moreover, prevention is cost-effective, its effects are not limited to high-risk subjects but extend to the entire population, and it is not dependent on socioeconomic status. Regulatory measures can have a broad impact, even on future generations; by empowering and educating subjects, promoting healthy behaviours and teaching self-care, they can trigger a virtuous cycle. In recent decades, oncology has shifted from being merely reactive to being proactive; this shift has led to the development of so-called "P4 medicine", where the 4 Ps stand for "preventive", "predictive", "personalized" and "participatory". Prevention programs are an important part of the effort to control cancer, as they are able to reduce both the incidence of cancer and mortality. For instance, screening for colorectal, breast and cervical cancer is reducing the burden of these common tumors. Anti-cancer vaccines, both prophylactic and therapeutic, constitute another important preventive tool. Although progress has been made in these areas, much remains to be done. With regard to screening programs, coverage could be increased by introducing new, more acceptable, less invasive tests, stratifying screening through correlation with anamnestic, clinical, radiological and genomic data (so-called "populationbased personalized cancer screening"), and exploiting new information and communication technologies, such as smartphone applications or personalized text messages (so-called "screening 2.0"). Advocacy and recommendations by physicians can also play a role, in that eligible subjects need to be able to discuss their doubts and their perceived psycho-social barriers. However, new screening initiatives should be implemented only after a careful health technology assessment has been performed within the framework of evidence-based medicine, organized screening programs have been strengthened and opportunistic or spontaneous programs have been limited.

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.

Abstract
High risk types of human papillomaviruses E6/E7 oncogenes and their association with tumor suppressor genes products are the key factors of cervical carcinogenesis. This study proposed them as specific markers for cervical dysplasia screening. The aim of the study is to compare the clinical and prognostic significance of HPV E6/E7 mRNA as an early biomarker versus HPV DNA detection and cytology in triage of woman for cervical cancer. The study group consists of 413 women: 258 NILM, 26 ASC-US, 81 LSIL, 41 HSIL, and 7 unsatisfactory cytology. HPV4AACE screening, real-time multiplex PCR and MY09/11 consensus PCR primers methods were used for the HPV DNA detection. The real-time multiplex nucleic acid sequence-based assay (NucliSENS EasyQ HPV assay) was used for HPV E6/E7 mRNA detection of the five most common high risk HPV types in cervical cancer (16, 18, 31, 33, and 45). The results show that HPV E6/E7 mRNA testing had a higher specificity 50% (95% CI 32-67) and positive predictive value (PPV) 62% (95% CI 46-76) for CIN2+ compared to HPV DNA testing that had specificity of 18% (95% CI 7-37) and PPV 52% (95% CI 39-76) respectively. The higher specificity and PPV of HPV E6/E7 mRNA testing are valuable in predicting insignificant HPV DNA infection among cases with borderline cytological finding. It can help in avoiding aggressive procedures (biopsies and over-referral of transient HPV infections) as well as lowering patient's anxiety and follow up period.
