Role of Dual-Staining p16/Ki-67 in the Management of Patients under 30 Years with ASC-US/L-SIL. Diagnostics (Basel) 2022; 12:diagnostics12020403. [PMID: 35204494 PMCID: PMC8870853 DOI: 10.3390/diagnostics12020403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 01/25/2022] [Accepted: 02/02/2022] [Indexed: 12/10/2022] Open
Abstract
Patients diagnosed with low-grade squamous intraepithelial lesion ((L-SIL) or atypical squamous cells of undetermined significance (ASC-US) are subjected to additional investigations, such as colposcopy and biopsy, to rule out cervical intraepithelial neoplasia 2+ (CIN 2+). Especially in young patients, lesions tend to regress spontaneously, and many human papilloma virus (HPV) infections are transient. Dual-staining p16/Ki-67 has been proposed for the triage of patients with ASC-US or L-SIL, but no prospective study addressing only this subgroup of patients has been conducted so far. We performed a prospective study including all eligible patients referred for a loop electrosurgical excision procedure (LEEP) in the Department of Obstetrics and Gynecology of Timișoara University City Hospital. HPV genotyping and dual-staining for p16/Ki-67 were performed prior to LEEP, at 6 and 12 months after LEEP. A total of 60 patients were included in the study and completed the follow-up evaluation. We analyzed the sensitivity and specificity for biopsy-confirmed CIN2+ using the 95% confidence interval (CI) of high-risk human papilloma virus (HR-HPV), dual-staining p16/Ki-67, colposcopy, and combinations of the tests on all patients and separately for the ASC-US and L-SIL groups. Dual-staining p16/Ki-67 alone or in combination with HR-HPV and/or colposcopy showed a higher specificity that HR-HPV and/or colposcopy for the diagnosis of biopsy confirmed CIN2+ in patients under 30 years. Colposcopy + p16/Ki-67 and HR-HPV + colposcopy + p16/Ki-67 showed the highest specificity in our study.

Elimination of cervical cancer in Tanzania: Modelled analysis of elimination in the context of endemic HIV infection and active HIV control. Int J Cancer 2021; 149:297-306. [PMID: 33634857 DOI: 10.1002/ijc.33533] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Revised: 01/24/2021] [Accepted: 02/10/2021] [Indexed: 01/17/2023]
Abstract
The World Health Organisation (WHO) has launched a strategic initiative for cervical cancer (CC) elimination which involves scaling up three interventions: human papillomavirus (HPV) vaccination, twice-lifetime HPV-screening screening and pre-cancer/cancer treatment by 2030. CC is challenging to control in countries with endemic human immunodeficiency virus (HIV), as women living with HIV (WLHIV) are at elevated risk of HPV infection, persistence and progression. This analysis estimated the impact of the elimination interventions on CC incidence and mortality but additionally considered more intensive screening for WLHIV, using Tanzania as an example. A dynamic HIV/HPV model was used to simulate the elimination strategy for vaccination, screening and pre-cancer/cancer treatment, with 3-yearly HPV-screening in WLHIV starting at age 25 years, in the context of sustained HIV control in Tanzania from 2020 to 2119. Without vaccination or HPV screening, CC incidence rates per 100 000 women are predicted to fall from 58.0 in 2020 to 41.6 (range: 39.1-44.7) in 2119, due to existing HIV control. HPV vaccination and twice-lifetime HPV-screening for the general population and 3-yearly screening for WLHIV, would reduce CC incidence to 1.3 (range: 1.3-2.5) by 2119, with elimination (<4/100 000) in 2076 (range: 2076-2092). CC mortality rates per 100 000 women are predicted to reach 1.1 (range: 1.1-2.1) with further reductions contingent on increased CC treatment access. Vaccination and 3-yearly HPV-screening for WLHIV is predicted to achieve elimination in the subgroup of WLHIV potentially as early as 2061 (range: 2061-2078), with a 2119 CC incidence rate of 1.7 (range: 1.7-3.3). Scaling-up vaccination and HPV-screening will substantially reduce CC incidence in Tanzania, with elimination predicted within a century. Three-yearly HPV-screening and HPV vaccination, at high coverage rates, would facilitate CC elimination among WLHIV, and thus accelerate elimination in the overall population.

Abstract
Introduction: Cervical cancer is the most common female cancer in large areas of the developing world, and almost half of these cases (54%) arises in Asia, where cervical cancer is still threatening women's health and survival, which makes it a considerable public problem. Human papillomavirus (HPV) is one of the most powerful human carcinogens. Today, it has been proven that all cervical cancers and primary precancerous lesions are caused by carcinogenic types of HPV infections. HPV genotyping can therefore evaluate the screening programs. Methods: Five hundred fifty women referring to the gynecological centers were subjected to Pap smear cell samples. The cytopathological diagnosis of obtained cervical samples was based on the Bethesda system. HPV genotyping was carried out using the INNO-LiPA HPV Genotyping Extra II Amp assay. Results: In a total of 244 HPV positive cases, single‑type HPV infec-tion was observed in 49.6%, while multi‑type HPV infections (including ≥ 2 types) were found in 45.5% of cases. Among the 110 cases with abnormal cytology results, going-over analyses led to the identification of atypical squamous cell of unknown significance (ASCUS) in 73 cases, low‑grade squamous intraepithelial lesions (LSIL) in 24 cases, and high‑grade squamous intraepithelial lesion (HSIL) in 12 cases. In these groups, the infection rate of high-risk HPV (HR-HPV) was 89%, 82%, and 100%, respectively. Conclusion: In this study, the total population of women suffering from different cervical lesions and malignancy was found to be infected with various HPV genotypes. High prevalence of HPV- 53 and HPV- 16 detected among participants with normal cytology can be considered as a tip-off development of cervical cancer among Iranian women.

Abstract
Answer questions and earn CME/CNE In this report, a team of surgical pathologists has provided a review of intraepithelial neoplasia in a host of (but not all) anatomic sites of interest to colleagues in various medical specialties, namely, uterine cervix, ovary, breast, lung, head and neck, skin, prostate, bladder, pancreas, and esophagus. There is more experience with more readily accessible sites (such as the uterine cervix and skin) than with other anatomic sites, and the lack of uniform terminology, together with divergent biology in various sites, makes it difficult to paint a unifying, relevant portrait. The authors' aim was to provide a framework from which to move forward as we care for patients with such precancerous lesions. CA Cancer J Clin 2016;66:408-436. © 2016 American Cancer Society.

Distribution of Human Papillomavirus Genotypes in Iranian Women According to the Severity of the Cervical Lesion. IRANIAN RED CRESCENT MEDICAL JOURNAL 2016; 18:e24458. [PMID: 27257511 PMCID: PMC4888845 DOI: 10.5812/ircmj.24458] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/10/2014] [Revised: 10/28/2014] [Accepted: 11/23/2014] [Indexed: 11/16/2022]
Abstract
BACKGROUND Persistent infection with high-risk human papillomavirus (HPV) has been recognized as a major cause of cervical cancer. Distribution of HPV genotypes may differ according to the geographic region and the severity of the cervical lesion. Determining HPV genotypes' specific distribution is useful for HPV surveillance and control programs. However, little is known about the distribution of HPV genotypes in Iranian women. OBJECTIVES The aim of this study was to determine the distribution of HPV genotypes in Iranian women with different grades of cervical lesions. PATIENTS AND METHODS From 2011 to 2013, a total of 436 Iranian women with convenience sampling strategy were included in this cross-sectional study. In detail, 287 women negative for intraepithelial lesion or malignancy, 32 with atypical squamous cells of undetermined significance (ASCUS), 50 with low-grade squamous intraepithelial lesion (LSIL), 44 with high-grade squamous intraepithelial lesion (HSIL), and 23 with cervical cancer were evaluated in this investigation. HPV genotypes were determined by INNO-LiPA HPV Genotyping Extra assay. RESULTS In total, HPV infection was detected in 45.4% of the cases. The most common high-risk HPV (HR-HPV) genotype was HPV-16 (32.8%), followed by HPV-53 (9.1%). Within low-risk (LR-HPV) genotypes HPV-6 (22.2%) and HPV-44 (6.1%) were the most prevalent. HPV-16 was the predominant genotype in cases with cervical cancer (56.5%), ASCUS (34.4%), and HSIL (34.1%). HPV-6 was the most common genotype in normal cases (9.1%) and LSIL patients (18%). The prevalence of HPV positivity was significantly higher in cases with high-grade lesions (≥ HSIL) (64.2%) than in normal/LSIL (37.3%) (P = 0.033). The rate of HR-HPV infection was significantly higher in ≥ HSIL cases (61.2%) than normal/LSIL (27.9%) (P = 0.003). CONCLUSIONS This study describes robust information on the distribution of HPV genotypes among Iranian women with and without cervical lesions. The present data may be of importance for designing future public health strategies, including HPV vaccination programs.

Abstract
Cervical cancer prevention strategies in the United States have become complicated and even controversial, despite advanced understanding of carcinogenic human papillomavirus (HPV) infection as the necessary causal agent. Twenty years ago, etiologic and methodologic studies had already yielded 2 powerful preventive approaches. There are excellent vaccines to prevent the most carcinogenic types of HPV infection; reduced HPV endemicity will ultimately prevent a large fraction of cervical precancer and cancers. For prevention of cervical cancer in the interim, sensitive HPV tests that target women at risk of cancer, by detection of the DNA/RNA of approximately a dozen carcinogenic HPV types, permit early diagnosis and treatment of precancers.Although HPV vaccines and tests have continued to improve, implementation of these new HPV-based prevention methods has been relatively slow in the United States and in most places worldwide. Increasing vaccination rates is the clearest and most vital long-term priority. But, for decades to come, screening will also be important. To promote useful discussion, this commentary will raise some current critical issues in simplifying and speeding the rational introduction of HPV molecular methods into US cervical screening.

Abstract
OBJECTIVES Cervical screening guidelines now recommend repeat cotesting of patients aged 30 years and older having a human papillomavirus (HPV)-negative low-grade squamous intraepithelial lesion (LSIL) in 1 year as preferred management. Only limited follow-up data on patients with HPV-negative LSILs are available from routine US clinical practice settings. METHODS In total, 680 patients with Hybrid Capture 2 (Qiagen, Hinden, Germany) high-risk HPV-negative LSIL ThinPrep (Hologic, Marlborough, MA) results were identified. Patients' ages and histopathologic, cytologic, and HPV follow-up results were identified. RESULTS Among 680 patients with HPV-negative LSILs, 468 had follow-up within 1 year. During the study period, 14 (3.0%) of 468 had follow-up high-grade squamous intraepithelial lesion (HSIL) and 184 (39.3%) LSIL findings. No diagnoses of cervical carcinoma were documented. There were no significant follow-up differences between age groups. Of the 321 patients who had follow-up HPV testing, 271 (84.4%) had negative and 50 (15.6%) had positive HPV results. CONCLUSIONS This is the largest study documenting follow-up results for patients with HPV-negative LSIL results based on prevalent US FDA-approved co-testing methods from one collection vial. These data document that risk for follow-up HSILs in these patients is low and also that no cervical cancers were diagnosed. These findings support recent recommendations for repeat co-testing after 1 year as an appropriate option for patients with HPV-negative LSIL results.

Abstract
Persistent infection with high-risk human papillomavirus (HPV) causes cervical preneoplasic lesions and invasive cervical cancer. This study evaluated the prevalence and distribution of HPV genotypes in cervical exfoliated cells from Uruguayan women. Five hundred sixty-eight cervical specimens were examined by PCR using MY09/11 primer set, and were genotyped by restriction enzyme digestion (RFLP). Some of the samples which remained undetermined were reanalyzed by PGMY PCR combined with reverse line blot hybridization. Overall, about 42% of samples were positive for HPV; 96% in high-grade squamous intraepithelial lesion, 66% in low-grade squamous intraepithelial lesion, 15% in atypical squamous cells of undetermined significance, and 19% in samples negative for intraepithelial lesion or malignancy. HPV 16 was the most commonly found genotype, followed by HPV 68 and 58. Within low risk-HPV genotypes 6, 61, and 11 were the most frequent. This is the first cross-sectional study, accounting for prevalence and genotype distribution of HPV in Uruguayan women.

Abstract
BACKGROUND Atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intra-epithelial lesions (LSIL) are minor lesions of the cervical epithelium, detectable by cytological examination of cells collected from the surface of the cervix of a woman.Usually, women with ASCUS and LSIL do not have cervical (pre-) cancer, however a substantial proportion of them do have underlying high-grade cervical intra-epithelial neoplasia (CIN, grade 2 or 3) and so are at increased risk for developing cervical cancer. Therefore, accurate triage of women with ASCUS or LSIL is required to identify those who need further management.This review evaluates two ways to triage women with ASCUS or LSIL: repeating the cytological test, and DNA testing for high-risk types of the human papillomavirus (hrHPV) - the main causal factor of cervical cancer. OBJECTIVES Main objective To compare the accuracy of hrHPV testing with the Hybrid Capture 2 (HC2) assay against that of repeat cytology for detection of underlying cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) or grade 3 or worse (CIN3+) in women with ASCUS or LSIL. For the HC2 assay, a positive result was defined as proposed by the manufacturer. For repeat cytology, different cut-offs were used to define positivity: Atypical squamous cells of undetermined significance or worse (ASCUS+), low-grade squamous intra-epithelial lesions or worse (LSIL+) or high-grade squamous intra-epithelial lesions or worse (HSIL+).Secondary objective To assess the accuracy of the HC2 assay to detect CIN2+ or CIN3+ in women with ASCUS or LSIL in a larger group of reports of studies that applied hrHPV testing and the reference standard (coloscopy and biopsy), irrespective whether or not repeat cytology was done. SEARCH METHODS We made a comprehensive literature search that included the Cochrane Register of Diagnostic Test Accuracy Studies; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE (through PubMed), and EMBASE (last search 6 January 2011). Selected journals likely to contain relevant papers were handsearched from 1992 to 2010 (December). We also searched CERVIX, the bibliographic database of the Unit of Cancer Epidemiology at the Scientific Institute of Public Health (Brussels, Belgium) which contains more than 20,000 references on cervical cancer.More recent searches, up to December 2012, targeted reports on the accuracy of triage of ASCUS or LSIL with other HPV DNA assays, or HPV RNA assays and other molecular markers. These searches will be used for new Cochrane reviews as well as for updates of the current review. SELECTION CRITERIA Studies eligible for inclusion in the review had to include: women presenting with a cervical cytology result of ASCUS or LSIL, who had undergone both HC2 testing and repeat cytology, or HC2 testing alone, and were subsequently subjected to reference standard verification with colposcopy and colposcopy-directed biopsies for histologic verification. DATA COLLECTION AND ANALYSIS The review authors independently extracted data from the selected studies, and obtained additional data from report authors.Two groups of meta-analyses were performed: group I concerned triage of women with ASCUS, group II concerned women with LSIL. The bivariate model (METADAS-macro in SAS) was used to assess the absolute accuracy of the triage tests in both groups as well as the differences in accuracy between the triage tests. MAIN RESULTS The pooled sensitivity of HC2 was significantly higher than that of repeat cytology at cut-off ASCUS+ to detect CIN2+ in both triage of ASCUS and LSIL (relative sensitivity of 1.27 (95% CI 1.16 to 1.39; P value < 0.0001) and 1.23 (95% CI 1.06 to 1.4; P value 0.007), respectively. In ASCUS triage, the pooled specificity of the triage methods did not differ significantly from each other (relative specificity: 0.99 (95% CI 0.97 to 1.03; P value 0.98)). However, the specificity of HC2 was substantially, and significantly, lower than that of repeat cytology in the triage of LSIL (relative specificity: 0.66 (95% CI 0.58 to 0.75) P value < 0.0001). AUTHORS' CONCLUSIONS HPV-triage with HC2 can be recommended to triage women with ASCUS because it has higher accuracy (significantly higher sensitivity, and similar specificity) than repeat cytology. When triaging women with LSIL, an HC2 test yields a significantly higher sensitivity, but a significantly lower specificity, compared to a repeat cytology. Therefore, practice recommendations for management of women with LSIL should be balanced, taking local circumstances into account.

Abstract
Low-grade squamous intraepithelial lesion (LSIL) is a common cytologic finding in cervical screening, yet only about 10-20% have significant histologic abnormalities and these are almost always positive for high-risk human papillomavirus (hrHPV). This analysis aims to clarify the role of hrHPV DNA testing in the triage of women with LSIL cytology. In the ATHENA screening trial, we examined 1,084 cases of LSIL, of which 925 had an evaluable biopsy, to determine the extent to which hrHPV testing can identify those patients who have precursor lesions in need of immediate clinical referral and those who have changes more likely to regress spontaneously. Overall, 71.2% of LSIL cases were hrHPV positive, but the prevalence was age dependent, with only 56.1% in women ≥ 40 years. Among women with LSIL, 11.6% (107/925) had a cervical intraepithelial neoplasia grade 2 or worse (CIN2+) histologic diagnosis and, of these, only nine were hrHPV negative. For CIN3+, 91.7% (44/48) of women with LSIL were hrHPV positive. The negative predictive value of hrHPV testing for CIN3+ in LSIL was 100% for women aged ≥ 40 years. Women who were HPV16 positive had a higher positive predictive value for CIN2+ (25.4%) than those who were positive for 12 other pooled hrHPV types (11.5%). Testing for hrHPV in women with LSIL is effective in identifying high-grade cervical lesions, thereby avoiding unnecessary referrals to colposcopy and potential over-treatment of non-progressive lesions, especially for women aged ≥ 40 years.

Abstract
The best method for identifying women who have minor cervical lesions that require diagnostic workup remains unclear. The authors of this report performed a meta-analysis to assess the accuracy of cyclin-dependent kinase inhibitor 2A (p16(INK4a)) immunocytochemistry compared with high-risk human papillomavirus DNA testing with Hybrid Capture 2 (HC2) to detect grade 2 or greater cervical intraepithelial neoplasia (CIN2+) and CIN3+ among women who had cervical cytology indicating atypical squamous cells of undetermined significance (ASC-US) or low-grade cervical lesions (LSIL). A literature search was performed in 3 electronic databases to identify studies that were eligible for this meta-analysis. Seventeen studies were included in the meta-analysis. The pooled sensitivity of p16(INK4a) to detect CIN2+ was 83.2% (95% confidence interval [CI], 76.8%-88.2%) and 83.8% (95% CI, 73.5%-90.6%) in ASC-US and LSIL cervical cytology, respectively, and the pooled specificities were 71% (95% CI, 65%-76.4%) and 65.7% (95% CI, 54.2%-75.6%), respectively. Eight studies provided both HC2 and p16(INK4a) triage data. p16(INK4a) and HC2 had similar sensitivity, and p16(INK4a) has significantly higher specificity in the triage of women with ASC-US (relative sensitivity, 0.95 [95% CI, 0.89-1.01]; relative specificity, 1.82 [95% CI, 1.57-2.12]). In the triage of LSIL, p16(INK4a) had significantly lower sensitivity but higher specificity compared with HC2 (relative sensitivity, 0.87 [95% CI, 0.81-0.94]; relative specificity, 2.74 [95% CI, 1.99-3.76]). The published literature indicated the improved accuracy of p16(INK4a) compared with HC2 testing in the triage of women with ASC-US. In LSIL triage, p16(INK4a) was more specific but less sensitive.

Abstract
A wealth of evidence has led to the conclusion that virtually all cases of cervical cancer are attributable to persistent infection by a subset of human papillomavirus (HPV) types, especially HPV type 16 (HPV-16) and HPV-18. These HPV types also cause a proportion of other cancers, including vulvar, vaginal, anal, penile, and oropharyngeal cancers. Although cervical cancer screening, primarily with the Papanicolaou (Pap) smear, has reduced the incidence of this cancer in industrialized countries, cervical cancer remains the second most common cause of death from cancer in women worldwide, because the developing world has lacked the resources for widespread, high-quality screening. In addition to advances in Pap smear technology, the identification of HPV as the etiologic agent has produced 2 recent advances that may have a major impact on approaches to reduce the incidence of this disease. The first is the development of a preventive vaccine, the current versions of which appear to prevent close to 100% of persistent genital infection and disease caused by HPV-16 and HPV-18; future second-generation vaccines may be able to protect against oncogenic infections by a broader array of HPV types. The second is the incorporation of HPV testing into screening programs. In women aged >30 years, HPV testing can identify high-grade cervical intraepithelial neoplasia earlier than Pap smears with acceptable rates of specificity. These results, together with the high sensitivity of HPV testing, suggest that such testing could permit increased intervals for screening. An inexpensive HPV test in development, if successful, may be incorporated as part of an economically viable 'screen-and-treat' approach in the developing world. The manner in which vaccination and screening programs are integrated will need to be considered carefully so that they are efficient in reducing the overall incidence of cervical cancer.

Abstract
OBJECTIVE To provide updated management guidelines according to cervical cytology specimen adequacy and techniques to optimize adequacy based on literature review and expert opinion. MATERIALS AND METHODS Selected members of the American Society for Colposcopy and Cervical Pathology committee and invited experts conducted a literature review and discussed appropriate management and areas for future research emphasis. RESULTS The guidelines recommend a repeat Pap test in a short interval of 2 to 4 months for most women when the cytology result is unsatisfactory. The preferred follow-up for women with a negative cytology result lacking an endocervical/transformation zone component or showing other quality indicators is a repeat Pap test in 12 months. Indications for an early repeat Pap test in 6 months are provided, and the influence of human papillomavirus testing results on management is discussed. Techniques for optimizing specimen adequacy are provided in detail. CONCLUSION The specimen adequacy management guidelines will help promote uniform and optimal follow-up of patients receiving cervical cytology screening. The topics for future research emphasis will be helpful in promoting studies in needed areas.

Abstract
BACKGROUND Human papillomavirus (HPV) testing has become part of cervicovaginal diagnostics in many laboratories. False-negative HPV results, even if rare, are potentially relevant clinically, particularly when testing is used alone. In this study, the authors investigated the occurrence and causes of abnormal cervicovaginal cytologies with negative HPV testing. METHODS The study was performed on 4130 liquid-based cytology (LBC) specimens from 2918 women who had abnormal cervical cytology or colposcopy or a history of abnormal cervical smear. HPV testing with Hybrid Capture II was repeated in LBC specimens with obviously atypical cytology (squamous intraepithelial lesion or abnormal squamous cells, cannot exclude high-grade lesion) and initial negative test results. The results were compared with the follow-up results and with the cytologic features of the specimens. RESULTS Of 4130 LBC specimens, 94 (2.28%) showed obviously abnormal cells despite negative HPV results, and 50 of those 94 samples (53.19%) were HPV-positive on a repeated testing of the same specimen. Histologic follow-up showed high-grade intraepithelial lesion or carcinoma in 10 specimens that initially were negative for HPV. Eight of those samples were HPV-positive on testing repetition. Both specimens that had persistently negative results had poor-quality cytologic samples at revision. CONCLUSIONS High-grade lesions may be identified in the follow-up of HPV-negative specimens with abnormal cytology. Testing repetition in patients with discordant cytology may prevent most potentially clinically relevant false-negative HPV results.

Abstract
OBJECTIVE This study compared the performance of cervical cytology plus human papilloma virus testing (Pap + HPV) or cervical spectroscopy (Pap + CS) for identifying high-grade cervical neoplasia in a high-risk population of women referred for colposcopy. MATERIALS AND METHODS Each of 113 subjects underwent spectroscopy, thin-layer cytology, HPV testing, colposcopy, biopsy when indicated, and/or endocervical curettage. Evaluable data for analysis were collected for 102 of the subjects. Sensitivity and specificity were calculated for both strategies. RESULTS Pap + HPV and Pap + CS achieved equivalent sensitivities (95%) for high-grade lesions, with both detecting 17 of 18 histology confirmed cervical intraepithelial neoplasia (CIN) 2+ lesions. Pap + HPV had a specificity of only 27.4% compared with 65.5% for Pap + CS (p < .0001). CONCLUSIONS Spectroscopic interrogation of the cervix is equally sensitive and 2-fold more specific than HPV testing when combined with cervical cytology for identifying high-grade cervical neoplasia.

Abstract
BACKGROUND Low-grade squamous intraepithelial lesion (LSIL) subsumes the formerly delineated cytologic categories of human papillomavirus (HPV)-associated cell changes (koilocytotic atypia) and low-grade dysplasia/cervical intraepithelial neoplasia (CIN) Grade 1 (CIN1). In this study, the objective was to determine whether these 2 morphologic subcategories are characterized by differences in risk for CIN3 and/or HPV type distribution. METHODS Within the Atypical Squamous Cells of Undetermined Significance/Low-Grade Squamous Intraepithelial Lesion Triage Study, all cytologic interpretations of HPV cellular changes and CIN1 rendered by any of the pathology reviewers (community laboratory, clinical center, or Pathology Quality-Control Group) on referral Papanicolaou (Pap) tests or enrollment ThinPrep Pap tests were included for analysis. HPV testing was performed by Hybrid Capture 2 (HC2) and by polymerase chain reaction based reverse-line blot analysis for 27 HPV types. The absolute risks of cumulative detection of CIN3 or cancer (CIN3 +) and CIN2 or worse (CIN2 +) over 2 years of follow-up were calculated for the various cytologic interpretations. RESULTS For each review group and cytology preparation, most LSIL interpretations (from approximately 2 of 3 interpretations to 3 of 4 interpretations) were subcategorized as CIN1 rather than HPV cellular changes. HPV type 16 (HPV-16) was the most common HPV type and was identified in 21% to 24% of CIN1 and in 14% to 18% of HPV cellular changes. Nononcogenic types were identified alone in from 9% to 11% of CIN1 compared with 17% to 20% of HPV cellular change. The absolute risks of CIN1 and HPV cellular changes for cumulatively detected CIN3 + ranged from 12% to 16% for CIN1 and from 6% to 9% for HPV cellular changes. CONCLUSIONS Both cytologic subcategories of LSIL were associated predominantly with oncogenic HPV types; however, the proportion of nononcogenic HPV types was lower and the absolute risks for CIN3 + were higher for CIN1 compared with HPV cellular changes. The concordance in subcategorizing LSIL was low, and the authors concluded that the diagnostic distinction is of limited clinical utility for individual patient management.

Abstract
BACKGROUND More than ever, clinicians need regularly updated reviews given the continuously increasing amount of new information regarding innovative cervical cancer prevention methods. MATERIAL AND METHODS A summary is given from recently published meta-analyses on three possible clinical applications of human papillomavirus (HPV)-DNA testing: triage of women with equivocal or low-grade cytological abnormalities; prediction of the therapeutic outcome after treatment of cervical intraepithelial neoplasia (CIN) lesions, and last not but not least, primary screening for cervical cancer and pre-cancer. RESULTS Consistent evidence is available indicating that HPV-triage with the Hybrid Capture-2 assay (HC2) is more accurate (significantly higher sensitivity, similar specificity) than repeat cytology to triage women with equivocal Pap smear results. When triaging women with low-grade squamous intraepithelial lesions (LSIL), a reflex HC2 test does not show a significantly higher sensitivity, but a significantly lower specificity compared to a repeat Pap smear. After treatment of cervical lesions, HPV testing easily detects (with higher sensitivity and not lower specificity) residual or recurrent CIN than follow-up cytology. Primary screening with HC2 generally detects 23% (95% confidence interval, CI: 13-23%) more CIN-2, CIN-3, or cancer compared to cytology at cut-off atypical squamous cells of undetermined significance (ASCUS) or LSIL, but is 6% (95% CI: 4-8%) less specific. By combined HPV and cytology screening, a further 4% (95% CI: 3-5%) more CIN-3 lesions can be identified but at the expense of a 7% (95% CI: 5-9%) loss in specificity, in comparison with isolated HC2 screening. CONCLUSIONS Sufficient evidence exists to recommend HPV testing in triage of women with atypical cytology and in surveillance after treatment of CIN lesions. In the United States, recently reviewed knowledge has resulted in the approval of combined cytology and HC2 primary screening in women older than 30 years. However, in Europe, cytology-based screening still remains the standard screening method. The European screening policy will be reviewed based on the longitudinal results of randomised population trials which are currently underway.

Abstract
The objective of this study was to assess the utility of a second generation human papillomavirus (HPV) virus-like particle (VLP)-based ELISA as an adjunct to HPV DNA testing to identify women at risk for high-grade cervical intraepithelial neoplasia (CIN). Participants provided blood, cervical samples and interviewer-obtained questionnaire information. HPV VLPs for types 16, 18, 33, 45 and 52 were produced using a baculovirus expression system. These highly purified VLPs were used in a polymer-based ELISA test. Cases with biopsy-confirmed CIN (CIN I, n = 237; CIN II, n = 56; CIN III, n = 48) and controls (n = 351) with normal Pap smears were tested for HPV DNA by PCR and serologic response to multiple oncogenic HPV VLPs. 258/341 (76%) of cases and 230/351 (65.5%) of control patients had any type of HPV VLP antibody (OR = 1.63, 95% CI 1.16-2.30). More cases were seropositive than controls for each individual HPV type (p < 0.001 for HPV types 16, 18, 33 and 45; p = 0.06 for HPV 52). Reactivity to an increasing number of different HPV type-specific VLPs are associated with high-grade CIN independent of HPV DNA status. HPV VLP assays may be useful as an adjunct to HPV DNA testing in a subset of patients that needs to be defined by further studies.
