Abstract
Background Cervical cancer is a leading cause of cancer-related deaths among women. However, in developing countries, the primary focus for cervical cancer prevention and control remains on the timely detection and treatment of precancerous lesions. This study aims to evaluate the accuracy of colposcopic diagnosis of cervical intraepithelial lesions and analyze the factors influencing its accuracy. Methods This study collected data from 512 eligible patients who visited the gynecology outpatient clinic of the Second Hospital of Jilin University from January 2022 to August 2023. The final diagnosis was based on the highest grade observed in both biopsy pathology and postoperative pathology. A self-controlled, retrospective analysis was conducted to evaluate the accuracy of colposcopic diagnosis. Univariate analysis was used to assess the impact of factors such as menopausal status, duration of menopause, high-risk human papillomavirus (HR-HPV) genotypes, and transformation zone (TZ) types on the accuracy of colposcopic diagnosis of cervical lesions. Result The overall colposcopy diagnostic concordance rate was 78.71%. The concordance rates between the premenopausal and postmenopausal groups differed significantly (χ 2 = 75.450, p < 0.05). The HPV16/18 positive group and the non 16/18 HR-HPV positive group also showed a significant difference in concordance rates (χ 2 = 5.890, p < 0.05). There were significant differences in concordance rates between TZ2 and TZ3 (χ 2 = 10.585, p < 0.05), as well as between TZ1 and TZ3 (χ 2 = 14.607, p < 0.05). Conclusion Factors such as menopausal status, duration of menopause, HR-HPV genotypes, and TZ types influence the accuracy of colposcopic diagnosis. Therefore, a comprehensive evaluation incorporating these factors should be performed in clinical practice to enhance diagnostic accuracy.

Abstract
Since the patients suffering from female lower genital tract diseases are getting younger and younger and the human papilloma virus (HPV) infection is becoming more widespread, the novel non-invasive precise modalities of diagnosis and therapy are required to remain structures of the organ and tissue, and fertility as well, by which the less damage to normal tissue and fewer adverse effects are able to be achieved. In all nucleated mammalian cells, 5-Aminolevulinic acid (5-ALA) is an amino acid that occurs spontaneously, which further synthesizes in the heme biosynthetic pathway into protoporphyrin IX (PpIX) as a porphyrin precursor and photosensitizing agent. Exogenous 5-ALA avoids the rate-limiting step in the process, causing PpIX buildup in tumor tissues. This tumor-selective PpIX distribution after 5-ALA application has been used successfully for tumor photodynamic diagnosis (PDD) and photodynamic therapy (PDT). Several ALA-based drugs have been used for ALA-PDD and ALA-PDT in treating many (pre)cancerous diseases, including the female lower genital tract diseases, yet the ALA-induced fluorescent theranostics is needed to be explored further. In this paper, we are going to review the studies of the mechanisms and applications mainly on ALA-mediated photodynamic reactions and its effectiveness in treating female lower genital tract diseases.

Extended Genotyping to Stratify the Risk of CIN2+ in Women with Persistent HPV Infection, Negative Cytology and Type 3 Transformation Zone. Cancers (Basel) 2024; 16:1816. [PMID: 38791895 PMCID: PMC11119326 DOI: 10.3390/cancers16101816] [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: 04/23/2024] [Revised: 05/05/2024] [Accepted: 05/08/2024] [Indexed: 05/26/2024] Open
Abstract
Persistent human papillomavirus (HPV) infection is recognized as a major risk factor for cervical cancer. Women with persistent HPV and negative cytology are at greater risk of CIN2+ than women with negative infection. The diagnosis becomes more complicated when the woman has a type 3 transformation zone at colposcopy. The aim of this study was to determine the prevalence of CIN2+ in women with persistent HPV, negative cytology and TZ3; how to stratify the risk of CIN2+; and what the best diagnostic strategy is, given TZ3. METHODS In a multicenter retrospective cohort study, we enrolled women with negative cytology and TZ3 among the 213 women referred for colposcopy for persistent HPV. The average age of the women was 53 years; in particular, 83% were postmenopausal women. In the presence of a TZ3, the entire transformation zone cannot be explored, making colposcopy and targeted biopsy useless and inadequate, with great risks of underdiagnosis or missed diagnosis. Women with TZ3 underwent diagnostic LEEP to ensure correct diagnoses. RESULTS The study highlighted 19% (16/84) of CIN2+ lesions, a higher frequency of non-HPV 16/18 genotypes (76.2%), and 50% of CIN2+ lesions being due to non-HPV 16/18 genotypes. Furthermore, more than half of the women (80.9%) had normal histopathological results in the LEEP sample. CONCLUSION Women with viral persistence, negative cytology, and TZ3 have a 19% risk of CIN2+; genotyping helps stratify risk, but extensive genotyping is necessary instead of partial genotyping (16/18), referring to a population of women over 50 years old in which the prevalence of genotypes 16,18 decreases and the prevalence of other genotypes increases; diagnostic LEEP is excessive (only 16 cases of CIN2+ out of 48 cases treated), even though 83% of women had viral clearance after LEEP; p16/Ki67 double staining could be a potential risk marker, which would only highlight women at risk of CIN2+ to undergo LEEP. To individualize the diagnostic workup and treatment and minimize the risk of under diagnosis and overtreatment, future studies should explore the use of extended genotyping and new biomarkers for individual risk stratification.

Abstract
OBJECTIVES The aims of this retrospective study were to evaluate the clinical applicability of the latest International Society for the Study of Vulvovaginal Disease (ISSVD) and International Federation for Cervical Pathology and Colposcopy (IFCPC) terminology for vulvar diseases, and to explore a new evaluation flow to optimize decision-making on diagnosis. METHODS A total of 1,068 patients with 5,340 qualified vulvar images were evaluated by observers using 2011 ISSVD and 2011 IFCPC terminology systems. The sensitivity, specificity, positive predictive value, negative predictive value, Youden Index and Overall Diagnostic Value (ODV) were calculated for each finding in the two systems. Then the disease diagnosis order and a diagnosis flow draft (DFD) were obtained. RESULTS A total of 15 kinds of vulvar diseases were diagnosed. The proportion of patients accompanied with cervical or vaginal intraepithelial neoplasia was highest (83.3 %) in vulvar Paget's disease group (p<0.001). Total area of lesions was larger in vulvar Paget's disease, lichen simplex chronicus and lichen sclerosus group (p<0.001). Among the top five findings of ODV, some findings inferred several (≥6) kinds of diseases, while some findings only exist in a certain disease. When the DFD was used, the agreement between the initial impression and histopathology diagnosis was 68.8 %, higher than those when ISSVD an IFCPC terminology systems used (p=0.028), and it didn't change with the experience of the observer (p=0.178). CONCLUSIONS Based on the findings in ISSVD and IFCPC terminology systems, we explored a DFD for observers with different experience on the detection of vulvar disease.

Abstract
OBJECTIVE Our aim was to evaluate the performance of different follow-up strategies after treatment for cervical intraepithelial neoplasia (CIN) 2 or 3, including human papillomavirus (HPV) detection, cytology, or colposcopy, as well as their combinations. Additionally, we compared the influence of the persistence of HPV 16/18 versus that of other high-risk HPV genotypes (HR-HPV) in the recurrence risk. METHODS Retrospective register-based study, including women who had an excision of the transformation zone for CIN2 or CIN3 at our institution, between January 2011 and December 2022. The outcome assessed was histopathological recurrence/persistence of CIN2 or worse. RESULTS Of the 721 women included, 6.8% (49/721) had recurrence/persistence. The sensitivity, specificity, and positive and negative predictive values of the HPV test were 97.4%, 80%, 22.3%, and 99.8%, respectively, whereas for cotesting (HR-HPV and cytology), 86.8%, 90.1%, 34.4%, and 99.1%, respectively. The referral rates for colposcopy were 24.3% and 14.2%, respectively. The sensitivity of colposcopy was low (40.0%).Women who were initially positive for non-16/18 genotypes at baseline who became HPV16/18 positive during follow-up, had a statistically significant increased risk of CIN2 or worse, compared with those who tested positive only for other HR-HPV genotypes during both stages (hazard ratio = 4.98; 95% CI = 1.66-14.91). CONCLUSIONS Human papillomavirus testing is the best strategy for follow-up after treatment of cervical HSIL. The addition of cytology triage decreases by more than 40% the referrals for colposcopy, without significantly missing cases of recurrence/persistence. Human papillomavirus 16/18 in the follow-up, regardless of being previously positive, is associated with higher risk of recurrence/persistence of HSIL.

Abstract
Simple Summary The spectrum of vulvar disorders is wide and varies from infections, dermatoses, manifestations of hormonal and systemic conditions to vulvar intraepithelial neoplasia (VIN) and invasive cancer. It is not always possible to distinguish vulvar lesions on the basis of macroscopical aspects and the distribution of changes. For definite diagnosis of a vulvar lesion, a biopsy is needed. However, in practice, the decision to perform a biopsy is often delayed due to a lack of specificity of symptoms at the early stages of the neoplastic disease. The aim of this article is to provide clinicians, both gynecologists and dermatologists, with the main features of vulvar precancerous lesions, in order to recognize and treat them on time, thus preventing vulvar cancer. Clinical appearance of VIN is variable with significant variations present in color, surface, and topography. Evaluation of all VIN lesions should be conducted very carefully, because an underlying early invasive squamous cancer appears to be present in a significant percentage of patients. Abstract The spectrum of vulvar lesions ranges from infective and benign dermatologic conditions to vulvar precancer and invasive cancer. Distinction based on the characteristics of vulvar lesions is often not indicative of histology. Vulvoscopy is a useful tool in the examination of vulvar pathology. It is more complex than just colposcopic examination and presumes naked eye examination accompanied by magnification, when needed. Magnification can be achieved using a magnifying glass or a colposcope and may aid the evaluation when a premalignant or malignant lesion is suspected. It is a useful tool to establish the best location for biopsies, to plan excision, and to evaluate the entire lower genital system. Combining features of vulvar lesions can help prediction of its histological nature. Clinically, there are two distinct premalignant types of vulvar intraepithelial neoplasia: HPV-related VIN, more common in young women, multifocal and multicentric; VIN associated with vulvar dermatoses, more common in older women and usually unicentric. For definite diagnosis, a biopsy is required. In practice, the decision to perform a biopsy is often delayed due to a lack of symptoms at the early stages of the neoplastic disease. Clinical evaluation of all VIN lesions should be conducted very carefully, because an underlying early invasive squamous cancer may be present.

Abstract
Recent evidence suggests that a cytology–histology correlation (CHC) with discrepancy detection can both evaluate errors and improve the sensitivity and specificity of the cytologic method. We aimed to analyze the errors in cytologic–histologic discrepancies according to the CHC protocol guideline of the American Society of Cytopathology (2017). This retrospective study included 273 patients seen at the National Medical Research Center of Obstetrics, Gynecology and Perinatology (Moscow, Russia) between January 2019 and September 2021. The patients’ mean age was 34 ± 8.1 years. The cytology–histology agreement was noted in 158 cases (57.9%). Major discrepancies were found in 21 cases (7.6%), while minor discrepancies were noted in 93 cases (34.1%). The reason for 13 (4.8%) discrepancies was a colposcopy sampling error and, in 46 (16.8%) cases, the reason was a Papanicolaou (PAP) test sampling error. The discrepancy between primary and reviewed cytology was due interpretive errors in 13 (4.8%) cases and screening errors in 42 (15.4%) cases. We demonstrated that the ASC guidelines facilitate cervical CHC. A uniform application of these guidelines would standardize cervical CHCs internationally, provide a scope for the inter-laboratory comparison of data, and enhance self-learning and peer learning.

Abstract
PURPOSE Colposcopy-guided punch biopsy is a cornerstone method for diagnosing vulvar diseases. The aim of this study was to evaluate the concordance rate of clinical findings in vulvar diseases during examinations, in comparison with colposcopy-directed punch biopsy. We also developed a new classification to simplify the categorization of vulvoscopic findings. METHODS The concordance rate of the clinical findings was compared with the final histology results from punch biopsies. The data were collected between January 2014 and May 2017 at the Erlangen University Hospital. RESULTS A total of 482 colposcopy-directed punch biopsies of the vulva were obtained in 420 women. The overall concordance rate of the clinical findings in comparison with the histological vulvar punch-biopsy findings was 53.9% for all entities - benign lesions, lichen, low- and high-grade squamous intraepithelial lesions (LSIL/HSILs), and vulvar carcinoma. The concordance rate for detecting LSILs was 64.3% (45/70). The concordance rate for detecting HSILs was 62.3% and for Vulvar carcinoma 65.2%. CONCLUSIONS Punch biopsy of suspicious lesions continues to be a cornerstone in diagnosing HSILs and carcinoma of the vulva. Careful work-up of the vulva is recommended when patients have symptoms such as pruritus or pain. The new classification is more specific for diagnosing lesions in the vulva.

Abstract
Background: Squamous intraepithelial lesions/cervical intraepithelial neoplasias (SIL/CIN) are high-risk human papilloma virus (hrHPV)-related lesions which are considered as high grade (HSIL/CIN2-3) or low grade (LSIL/CIN1) lesions according to their risk of progression to cervical cancer (CC). Most HSIL/CIN2-3 are considered as transforming hrHPV infections, so truly CC precursors, although some clear spontaneously. hrHPV testing has a high sensitivity for the detection of HSIL/CIN2-3 but a relatively low specificity for identifying transforming lesions. We aimed to determine whether the combination of CADM1, MAL and miR124 promoter methylation status assessed in histological samples can be used as a biomarker in the identification of transforming HSIL/CIN lesions. Design: 131 cervical biopsies, including 8 cases with no lesion and a negative hrHPV test result (control group), 19 low-grade (L)SIL/CIN1, 30 HSIL/CIN2, 60 HSIL/CIN3, and 14 CC were prospectively collected. hrHPV was detected and genotyped using the polymerase chain reaction (PCR)-based technique SPF10 HPV LIPA. A multiplex quantitative methylation-specific PCR (qMSP) was used to identify the methylation status of the CADM1, MAL, and miR124 promoter genes. Results: Significantly higher methylation levels of CADM1, MAL and miR-124 were found in HSIL/CIN2-3 and CC compared with normal and LSIL lesions. DNA methylation of at least one gene was detected in 12.5% (1/8) of normal samples, 31.5% (6/19) of LSIL/CIN1, 83.3% (25/30) of HSIL/CIN2, 81.6% (49/60) of HSIL/CIN3 and 100% (14/14) of CC (p < 0.001). The sensitivity and specificity for HSIL/CIN2-3 and CC of having at least one methylated gene were 84.6% and 74.0%, respectively. The sensitivity and specificity of the combination of at least one methylated gene and a positive hrHPV test were 80.7% and 85.1% for HSIL/CIN2-3 and CC, respectively. Conclusions: The methylation rate of CADM1, MAL and miR124 increases with the severity of the lesion. Further research is warranted to evaluate the usefulness of these biomarkers for the identification of transforming HSIL/CIN.

Abstract
Supplemental digital content is available in the text. Objective The aim of the study was to investigate the value of cytology, high-risk human papillomavirus (hrHPV) status and colposcopy in the early diagnosis of vaginal cancer after hysterectomy. Materials and Methods A retrospective study was performed in the Obstetrics and Gynecology Hospital of Fudan University. Posthysterectomy patients who were diagnosed with vaginal high-grade intraepithelial lesion (HSIL) by colposcopy-directed biopsy with colposcopy impression of extensive HSIL or suspicion of cancer and underwent upper or total vaginectomy from January 2009 to December 2017 were included. Results Eighty-six posthysterectomy vaginal HSIL patients were included. Available abnormal cytology and positive hrHPV were observed in 90.7% (49/54) and 96.2% (51/53) of the patients, respectively. A total of 18.6% (16/86) of the patients were diagnosed with squamous cell cancer by vaginectomy, and the average interval between hysterectomy and vaginectomy was 3.5 years. Among them, 62.5% (10/16) cancers occurred after hysterectomy for cervical cancer, 31.2% (5/16) after hysterectomy for cervical precancer, and 6.3% (1/16) after hysterectomy for myoma. An indication for hysterectomy (cervical cancer vs HSIL, odds ratio = 7.2, 95% CI = 1.9–28.0, p = .004) and colposcopy impression of vaginal cancer (vaginal cancer vs HSIL, odds ratio = 5.9, 95% CI = 1.3–26.8, p = .021) were high-risk factors of cancer confirmed by vaginectomy in colposcopy-directed biopsy vaginal intraepithelial neoplasia 2/3 posthysterectomy in multiple logistic regression analysis. Conclusions Colposcopy is pivotal in the evaluation of abnormal cytology/hrHPV tests in follow-up of cervical cancer patients after hysterectomy and decision-making for vaginectomy in detecting early cancer.

Abstract
PURPOSE The aim of this study was to analyze the diagnostic performance of a newly established immunocytochemical dual-staining protocol for the simultaneous expression of SEC62 and Ki67 in vulvar liquid-based cytology specimens for the identification of vulvar intraepithelial neoplasia (VIN) and vulvar cancer. In addition, we investigated the p16/Ki67 dual stain, which has already been established in cervical cytology. MATERIALS AND METHODS For this pilot study, residual material from liquid-based cytology was collected retrospectively from 45 women. The presence of one or more double-immunoreactive cells was considered as a positive test result for Sec62/Ki67 and p16/Ki67 dual staining. The test results were correlated with the course of histology. RESULTS All cases of VIN and vulvar cancer were Sec62/Ki67 and p16/Ki67 dual-stain positive, and normal and low-grade squamous intraepithelial lesions were all negative. The sensitivity of cytology for VIN + cases was 100% (22/22), whereas punch biopsy classified one case of vulvar carcinoma as inflammation. All cases with high-intensity (grades 3 and 4) Sec62 staining in Sec62/Ki67-positive cases were carcinomas. CONCLUSIONS The results of this study demonstrate that Sec62/Ki67 and p16 Ki67 dual-staining cytology could be a promising adjunctive diagnostic tool for VIN and squamous cell carcinoma, in addition to standard histology.

Abstract
During pregnancy, the only diagnosis that may alter management is invasive cancer. Thus, the primary aim of the cytological screening and subsequent colposcopy performed during pregnancy should be the exclusion of invasive cancer, “Practice Bulletin No. 140: management of abnormal cervical cancer screening test results and cervical cancer precursors,” (American College of Obstetricians and Gynecologists, 2013) [1]. However, the impact of the delivery on the regression of the cervical lesions is still debated. This data article concerns the post-partum evaluation of colposcopic patterns, cytological and histopathology findings in women diagnosed with abnormal cervical cytology in pregnancy, included in the paper entitled “Reliability of colposcopy during pregnancy” (Ciavattini et al., 2018). Data about the rates of persistence, progression and regression of CIN after delivery are reported.

Abstract
HPV-based screening provides greater protection against cervical cancer (CC) than cytology-based strategies. Currently, several molecular diagnostic assays for the detection of human papillomavirus (HPV) are available. In this study, we analyzed 5 different HPV testing and genotyping techniques (Hybrid Capture 2 [HC2; Qiagen, Hilden, Germany], AnyplexTMII HPV28 [Anyplex; Seegene, Seoul, Korea], Linear Array [Roche, Branchburg, NJ, USA], GP5+/6+ PCR-EIA-RH [Labo Bio-medical Products, Rijswijk, The Netherlands] and CLART2 [Genomica, Madrid, Spain]) in 295 women referred to the hospital Colposcopy Clinic from 2007 to 2008 due to positive HPV test results or an abnormal Pap test. DNA extraction for HPV genotyping was performed in cervical sample specimens after Pap test and HPV detection by HC2. The inclusion criteria were: (1) adequate cervical sampling with sufficient material for the Pap test and HPV detection and genotyping, and (2) colposcopically-directed biopsy and/or endocervical curettage. HC2 showed the highest sensitivity for high-grade squamous intraepithelial lesion and CC (HSIL+) detection (96.1%), but all the HPV genotyping tests showed a higher specificity. (Anyplex 86.8%; Linear Array 86.0%; GP5+/6+ 78.8%; CLART2 76.5%). The agreement between HC2 results and the other techniques was similar: 82.4%, kappa=0.650 for Anyplex; 83.4%, kappa=0.670 for Linear Array, 79.93%, kappa=0.609 for GP5+/6+ and 82.4%, kappa=0.654 for CLART2. HPV 16 and/or 18 infection was a risk factor for underlying HSIL+ in the univariate analysis. Anyplex showed the highest risk of underlying HSIL+ after positive HPV 16 and/or 18 tests (OR 31.1; 95% CI 12.1-80.0).

Abstract
Human papillomaviruses (HPVs) are the necessary cause of most cervical cancers, a large proportion of other anogenital cancers, and a subset of oropharyngeal cancers. The knowledge about HPV has led to development of novel HPV-based prevention strategies with important impact on clinical and public health practice. Two complementary reviews have been prepared following the 2015 Eurogin Conference to evaluate how knowledge about HPV is changing practice in HPV infection and disease control through vaccination and screening. This review focuses on screening for cervical and anal cancers in increasingly vaccinated populations. The introduction of HPV vaccines a decade ago has led to reductions in HPV infections and early cancer precursors in countries with wide vaccination coverage. Despite the high efficacy of HPV vaccines, cervical cancer screening will remain important for many decades. Many healthcare systems are considering switching to primary HPV screening, which has higher sensitivity for cervical precancers and allows extending screening intervals. We describe different approaches to implementing HPV-based screening efforts in different healthcare systems with a focus in high-income countries. While the population prevalence for other anogenital cancers is too low for population-based screening, anal cancer incidence is very high in HIV-infected men who have sex with men, warranting consideration of early detection approaches. We summarize the current evidence on HPV-based prevention of anal cancers and highlight important evidence gaps.

Abstract
AIM To analyse the regression rate and the risk of persistence or progression of the lesions in women with a histopathological diagnosis of cervical low-grade squamous intraepithelial lesion (LSIL). MATERIALS AND METHODS Retrospective cohort study of women with biopsy diagnosis of cervical LSIL, from January 2010 to December 2013. After the initial diagnosis of LSIL, all the women underwent scheduled follow-up examinations with cytology every 6 months for 2 years and an HPV test after 1 year. RESULTS At the 24 -month follow-up, the regression of cervical LSIL was observed in 88.5% of the women. 10.8% of the women had a persistent lesion, while a progression towards cervical HSIL was reported in 0.7% of the women. The risk of persistence or progression of histological LSIL was higher in women with ASC-H or HSIL on the referral cytology and in tobacco users. CONCLUSION In women with biopsy diagnosis of cervical LSIL, preceded by ASCUS or LSIL on cytology, a high rate of regression was observed and, in most of the cases, the regression occurred in the first year of follow-up. In women with cervical LSIL, preceded by ASC-H or HSIL on cytology, and in tobacco users, a higher risk of persistence and progression was observed. Thus, in these cases, repeated follow-up examinations, even with the HR-HPV test, are advisable.

Abstract
Infections with human papillomavirus (HPV) are common and transmitted by direct contact. Although the great majority of infections resolve within 2 years, 13 phylogenetically related, sexually transmitted HPV genotypes, notably HPV16, cause - if not controlled immunologically or by screening - virtually all cervical cancers worldwide, a large fraction of other anogenital cancers and an increasing proportion of oropharyngeal cancers. The carcinogenicity of these HPV types results primarily from the activity of the oncoproteins E6 and E7, which impair growth regulatory pathways. Persistent high-risk HPVs can transition from a productive (virion-producing) to an abortive or transforming infection, after which cancer can result after typically slow accumulation of host genetic mutations. However, which precancerous lesions progress and which do not is unclear; the majority of screening-detected precancers are treated, leading to overtreatment. The discovery of HPV as a carcinogen led to the development of effective preventive vaccines and sensitive HPV DNA and RNA tests. Together, vaccination programmes (the ultimate long-term preventive strategy) and screening using HPV tests could dramatically alter the landscape of HPV-related cancers. HPV testing will probably replace cytology-based cervical screening owing to greater reassurance when the test is negative. However, the effective implementation of HPV vaccination and screening globally remains a challenge.

Abstract
BACKGROUND Persistent infections with human papillomaviruses are a necessary cause of cervical carcinomas. The development of HPV-based prevention tools, HPV vaccination and HPV testing, is leading to major changes in cervical cancer prevention programs worldwide. A decade after introduction of HPV vaccination in many countries reductions of HPV infections and cancer precursors have been observed in young women. The focus is now on the integration of new approaches for screening of increasingly vaccinated populations. RESULTS AND CONCLUSIONS A successful cervical cancer prevention program includes primary screening, triage of screen-positives, and colposcopy-biopsy to identify women with cancer precursors who require treatment. The role of primary screening is to identify a small subset of women with increased risk of cervical precancer, while the majority of women can be reassured that their risk is very low. Depending on the primary screening test, additional triage testing is required to decide who should be referred to colposcopy. Currently, there are three major approaches to cervical cancer screening: Cervical cytology, HPV testing, and HPV-cytology co-testing. Several triage tests for HPV-positive women are currently being evaluated, including cytology, HPV genotyping, p16/Ki-67 cytology and various methylation tests. Due to the increasing number of options for cervical cancer screening, it is challenging to keep screening guidelines current and comprehensible. The increasing complexity can lead to confusion among providers and women who participate in screening programs about the best approaches. Precision prevention is a novel approach to cervical cancer screening that integrates individual medical history with test results for unified, risk-based management decisions.

Abstract
OBJECTIVE High-resolution anoscopy (HRA) is a useful screening tool for anal intraepithelial neoplasia (AIN), although reputedly challenging for interpretation of suspected lesions. MATERIALS AND METHODS All consecutive patients who underwent biopsies for at least 1 lesion suspicious for AIN during HRA from November 2010 to March 2012 were prospectively included. The characteristics (borders, staining with acetic acid and Lugol iodine solution, and patterns of epithelium and vascularization) of the lesions detected during HRA were compared with histology. RESULTS A total of 168 suspicious anal lesions were biopsied and analyzed in 103 patients (68% men, mean age ± standard deviation = 49.8 ± 9 y, 57% positive status on human immunodeficiency virus infection). According to histology, 41.7% of the lesions were high grade, 34.5% were low grade, and 23.8% were nondysplastic. Lesions with irregular epithelial pattern (or irregular vascularization) were twice as likely to be high grade compared with lesions with regular epithelial pattern (or regular vascularization). The incidences of acetic acid-induced whitening were 91.4%, 94.8%, and 70% among the high-grade AIN, low-grade AIN, and nondysplastic samples, respectively. Among the high-grade AIN, 62.9% were not stained by Lugol solution (vs 31% of the low-grade AIN). The positive predictive value of a combination of these simple morphological criteria was 68.6%. CONCLUSIONS Several simple morphological criteria are significantly associated with high-grade AIN and are found less often in low-grade AIN. A combination of these morphological criteria provides sufficient positive predictive value to guide biopsy placement during HRA.

Abstract
For this tribute to Mario Sideri, we reviewed some of the current issues in colposcopy, many of which we were researching with him. The review concentrates on the impact of HPV testing on cervical screening, specifically on the practice of colposcopy as the major diagnostic procedure in cervical screening programmes. Topics include the changing population of women referred to colposcopy, evolving views of the colposcopic impression, differing approaches to directed and random biopsy, issues in teaching colposcopy using static images, and the development of colposcopy aids, and simplified visual assessment techniques.

Abstract
Pruritus of the vulva is a common symptom among patients attending to outpatient clinics. In the present study, we aimed to assess pathologies causing vulval pruritus in the reliability of biopsy in a tertiary referral centre. A total of 137 patients undergoing vulval colposcopy because of vulval pruritus were reviewed from the hospital records retrospectively. The mean age of the patients was 47.61 ± 11.88 years and 36.5% of the patients were postmenopausal. In 101 (73.7%) of the patients, macroscopic lesions were present. In 88 (64.2%) of the patients, tolidine-positive stained areas were determined under colposcopy. In total, 68 (49.6%) of the lesions were plain, whereas 51 (37.2%) of them were depigmented. Lichen simplex chronicus, lichen sclerosis and chronic inflammation were the major pathologies associated with vulval pruritus (25.5%, n = 35; 20.4%, n = 28; 14.6%, n = 20). In conclusion, several pathologies out of vulvovaginal candidiasis may lead to vulval pruritus and clinicians should be aware of the importance of biopsy in determining the underlying pathology.

Abstract
This article describes the current nomenclature of colposcopic findings in the lower genital tract as defined by the International Federation for Cervical Pathology and Colposcopy (IFCPC) and agreed at their Triennial General Meeting in July 2012 in Rio de Janeiro. It builds on previous nomenclature published by the IFCPC over the last two decades and introduces for the first time the concept of transformation zone excision types. Vulval and vaginal colposcopic terminology is described.

Abstract
In July 2012 a revised terminology on colposcopic examinations of the cervix uteri was adopted by IFCPC. Central aspect is a description of characteristics that should aid in the definition of the disease entity cervix uteri. The nomenclature is built up in such a way that the examiner can evaluate colposcopic criteria according to a specific scheme. Firstly it is assessed whether the colposcopy is representative. Then it should be clarified whether or not the findings are normal. If the findings are not normal but rather abnormal the severity of the lesion is classified according to the so-called grade 1 (minor change) and grade 2 findings (major change). Specific abnormal findings such as leukoplakia, erosion and Lugol's finding are also not defined at this point. Characteristics suspicious for an invasion are described separately, in particular, atypical vessel patterns are mentioned here. As already held in the previous revised nomenclature (Barcelona), various findings are described in a last group: congenital transformation zones (CTZ), congenital anomalies, condylomas (papillomas), endometriosis, polyps (ectocervical, endocervical), inflammation, stenosis, postoperative changes (scarred portio, vaginal stump).
