RESUMEN

OBJECTIVES: This study is reporting the CO2 laser treatment efficiency on urethral lesions caused by human papillomavirus (HPV) and the correlation between the type of lesion high-grade and low-grade on the histology and the HPV genotype(s). METHODS: Sixty-nine patients (59 men and 10 women) with urethral lesions were screened for HPV genotype(s) by in situ hybridisation and PCR. HPV lesions were biopsied and p16INK4a expression was tested to confirm urethral high-grade squamous intraepithelial lesions (U HSIL) on the histology prior to CO2 laser treatment under colposcopy. The patients were followed up for 12 months. RESULTS: We observed urethral low-grade squamous intraepithelial lesions (U LSIL) in 54/69 cases (78.3%) and U HSIL in 7/69 cases (10%) confirmed by p16INK4a staining. Then we looked at the HPV genotype present in each lesion. We observed the following: 31/69 (45%) patients have a unique HPV genotype, with 12/31 (38.7%) of high risk; 21/54 (38.8%) of U LSIL and 1/7 (14%) of U HSIL have HPV low-risk and high-risk coinfections. Efficient treatment with CO2 laser under colposcopy was done using a meatal spreader to help visualisation of 20 mm in the distal urethra. We cured 64/69 (92.7%) patients at 3 months with 4/69 (5.7%) meatotomy and persistent 1/67 (1.4%) urethral stricture at 12 months. CONCLUSIONS: HSIL was present in the urethra without being able to define specific clinical criteria. Treatment with a CO2 laser under colposcopy with a meatus spreader is a simple surgical procedure with high efficiency and few complications that could prevent the risk of HPV-induced carcinoma.

RESUMEN

The french society of pathology (SFP) organized in 2020 its first data challenge with the help of Health Data Hub (HDH). The organisation of this event first consisted in recruiting almost 5000 slides of uterus cervical biopsies obtained in 20 pathology centers. After having made sure that patients did not refuse to include their slides in the project, the slides were anonymised, digitized and annotated by expert pathologists, and were finally uploaded on a data challenge platform for competitors all around the world. Competitors teams had to develop algorithms that could distinguish among four diagnostic classes in epithelial lesions of uterine cervix. Among many submissions by competitors, the best algorithms obtained an overall score close to 95%. The best 3 teams shared 25k€ prizes during a special session organised during the national congress of the SFP. The final part of the competition lasted only 6 weeks and the goal of SFP and HDH is now to allow for the collection to be published in open access. This final step will allow data scientists and pathologists to further develop artificial intelligence algorithms in this medical area.

RESUMEN

The age-standardised incidence of cervical cancer in Europe varies widely by country (between 3 and 25/100000 women-years) in 2018. Human papillomavirus (HPV) vaccine coverage is low in countries with the highest incidence and screening performance is heterogeneous among European countries. A broad group of delegates of scientific professional societies and cancer organisations endorse the principles of the WHO call to eliminate cervical cancer as a public health problem, also in Europe. All European nations should, by 2030, reach at least 90% HPV vaccine coverage among girls by the age of 15 years and also boys, if cost-effective; they should introduce organised population-based HPV-based screening and achieve 70% of screening coverage in the target age group, providing also HPV testing on self-samples for nonscreened or underscreened women; and to manage 90% of screen-positive women. To guide member states, a group of scientific professional societies and cancer organisations engage to assist in the rollout of a series of concerted evidence-based actions. European health authorities are requested to mandate a group of experts to develop the third edition of European Guidelines for Quality Assurance of Cervical Cancer prevention based on integrated HPV vaccination and screening and to monitor the progress towards the elimination goal. The occurrence of the COVID-19 pandemic, having interrupted prevention activities temporarily, should not deviate stakeholders from this ambition. In the immediate postepidemic phase, health professionals should focus on high-risk women and adhere to cost-effective policies including self-sampling.

RESUMEN

BACKGROUND: The purpose of this study was to compare cervical cancer screening by pap smear (PS) versus preliminary HPV testing based on self-collected samples (SC-HPV). METHODS: Interventional study among underprivileged women from 25 to 65 years old in four French cities. The control group (CG) was referred for a PS. The experimental group (EG) conducted a SC-HPV test followed by a PS in case of positivity. Differences on screening completion and cytological abnormalities were analysed by logistic and Cox regression. RESULTS: 383 women were assigned to the EG and 304 to the CG. The screening completion proportion was 39.5% in the CG compared to 71.3% in the EG (HR = 2.48 (CI 95% [1.99-3.08]; p < 0.001). The proportion of cytological abnormalities was 2.0% in the CG and 2.3% in the EG (OR = 1.20 (CI 95% [0.42-3.40]; p = 0.7). The proportion of participants lost to follow-up was 60.5% in the CG and 63.2% in the EG HPV positive (p = 0.18). CONCLUSION: Providing an SC-HPV-test increased the participation of underprivileged women in CCS. Nevertheless, the significant number of lost to follow-up in both groups can undermine the initial benefits of the strategy for HPV positive women. Registration: Clinicaltrials.gov: NCT03118258.

RESUMEN

This paper summarises the position of ESGO and EFC on cervical screening based on existing guidelines and opinions of a team of lead experts. HPV test is replacing cytology as this offers greater protection against cervical cancer and allows longer screening intervals. Only a dozen of HPV tests are considered as clinically validated for screening. The lower specificity of HPV test dictates the use of triage tests that can select women for colposcopy. Reflex cytology is currently the only well validated triage test; HPV genotyping and p16 immunostaining may be used in the future, although methylation assays and viral load also look promising. A summary of quality assurance benchmarks is provided, and the importance to audit the screening histories of women who developed cancer is noted as a key objective. HPV-based screening is more cost-effective than cytology or cotesting. HPV-based screening should continue in the post-vaccination era. Only a fraction of the female population is vaccinated, and this varies across countries. A major challenge will be to personalise screening frequency according to vaccination status. Still the most important factor for successful prevention by screening is high population coverage and organised screening. Screening with self-sampling to reach under-screened women is promising.

RESUMEN

RESEARCH QUESTION: What are the effects of ulipristal acetate (UPA) on the expression of endometrial proliferation and maturation markers? DESIGN: A total of 45 endometrium-containing blocks of hysterectomy samples from non-menopausal women with a diagnosis of moderate to severe symptoms of uterine fibroids: 14 women operated on at the end of a 3-month course of UPA; four women who had discontinued UPA treatment 1-12 months before surgery; 27 control unexposed samples (14 in the proliferative and 13 in the secretory phase). Immunohistochemical staining of Ki67, vascular endothelial growth factor-receptor 2 (VEGFR2), oestradiol receptor, progesterone receptor, interleukin-15 (IL-15), indoleamin-2,3-dioxygenase (IDO) and C-C motif chemokine ligand-2 (CCL2) markers were analysed in both endometrial compartments and layers. RESULTS: Under UPA, oestradiol receptor and progesterone receptor expression is similar to the proliferative phase in both layers, although with a decrease in cell proliferation. IL-15, IDO and CCL2 expressions are similar to the proliferative phase, suggesting a progesterone-antagonist effect of UPA. VEGFR2 staining suggests a trend to a mixed agonist-antagonist effect. No significant difference is observed in the post-UPA proliferative phase group compared with the control group in both layers of the endometrium. CONCLUSION: The effect of 3-month UPA treatment is mostly progesterone receptor antagonist-like. After treatment is discontinued, there are no signs of any long-term effects of this molecule on endometrial proliferation and maturation. Therefore, UPA may be administered to women willing to conceive in the short term without consequences for further implantation.

RESUMEN

Ulipristal acetate (UPA) is used to treat leiomyomas, and its effect on the endometrium has been studied in biopsy material. Reversible histologic modifications were found, named progesterone receptor modulators-associated endometrial changes (PAEC). However, hysterectomies from patients treated with UPA have not been analyzed. For the first time, we examined surgical specimens from 100 leiomyoma-treated patients for UPA-related endometrial changes. We analyzed the distribution of lesions, involution after treatment, and the relationship between type and extent of lesions and dosage. Clinically, 72 patients were treated with 1 cycle of UPA; 23 patients with 2 cycles, and 5 with 3 cycles. A total of 66 patients underwent surgery in the first 4 wk after treatment, 24 were operated between 5 and 12 wk after discontinuation of UPA, and 10 after more than 12 wk after the last cycle, up to a maximum of 32 wk. Histologically normal endometria were found in 41 cases and PAEC in 59 cases. PAEC consisted of irregular, cystic glands showing a flattened secretory-like epithelium with vacuolation, coexisting mitoses and apoptosis, and were found focally within cyclic endometria in 51 cases. Only in 8 cases did diffuse PAEC involve the whole endometrium, transforming it into a thick spongy cushion. PAEC also occurred in adenomyosis. There was no relationship between dosage and type and extent of lesions. Diffuse PAEC, which usually presents differential diagnoses with hyperplasia, occurred in only 8 cases, being only present during the first 4 wk after discontinuation of treatment and was independent of the number of cycles administered.

RESUMEN

BACKGROUND: Incomplete excision of cervical precancer is associated with therapeutic failure and is therefore considered as a quality indicator of clinical practice. Conversely, the risk of preterm birth is reported to correlate with size of cervical excision and therefore balancing the risk of adequate treatment with iatrogenic harm is challenging. We reviewed the literature with an aim to reveal whether incomplete excision, reflected by presence of precancerous tissue at the section margins, or post-treatment HPV testing are accurate predictors of treatment failure. METHODS: We did a systematic review and meta-analysis to assess the risk of therapeutic failure associated with the histological status of the margins of the tissue excised to treat cervical precancer. We estimated the accuracy of the margin status to predict occurrence of residual or recurrent high-grade cervical intraepithelial neoplasia of grade two or worse (CIN2+) and compared it with post-treatment high-risk human papillomavirus (HPV) testing. We searched for published systematic reviews and new references from PubMed-MEDLINE, Embase, and CENTRAL and did also a new search spanning the period Jan 1, 1975, until Feb 1, 2016. Studies were eligible if women underwent treatment by excision of a histologically confirmed CIN2+ lesion, with verification of presence or absence of CIN at the resection margins; were tested by cytology or HPV assay between 3 months and 9 months after treatment; and had subsequent follow-up of at least 18 months post-treatment including histological confirmation of the occurrence of CIN2+. Primary endpoints were the proportion of positive section margins and the occurrence of treatment failure associated with the marginal status, in which treatment failure was defined as occurrence of residual or recurrent CIN2+. Information about positive resection margins and subsequent treatment failure was pooled using procedures for meta-analysis of binomial data and analysed using random-effects models. FINDINGS: 97 studies were eligible for inclusion in the meta-analysis and included 44 446 women treated for cervical precancer. The proportion of positive margins was 23·1% (95% CI 20·4-25·9) overall and varied by treatment procedure (ranging from 17·8% [12·9-23·2] for laser conisation to 25·9% [22·3-29·6] for large loop excision of the transformation zone) and increased by the severity of the treated lesion. The overall risk of residual or recurrent CIN2+ was 6·6% (95% CI 4·9-8·4) and was increased with positive compared with negative resection margins (relative risk 4·8, 95% CI 3·2-7·2). The pooled sensitivity and specificity to predict residual or recurrent CIN2+ was 55·8% (95% CI 45·8-65·5) and 84·4% (79·5-88·4), respectively, for the margin status, and 91·0% (82·3-95·5) and 83·8% (77·7-88·7), respectively, for high-risk HPV testing. A negative high-risk HPV test post treatment was associated with a risk of CIN2+ of 0·8%, whereas this risk was 3·7% when margins were free. INTERPRETATION: The risk of residual or recurrent CIN2+ is significantly greater with involved margins on excisional treatment; however, high-risk HPV post-treatment predicts treatment failure more accurately than margin status.

RESUMEN

Quality assurance and research in colposcopy and cervical pathology require standardized terminologies and reporting. However, clinical and histologic definitions of the cervical transformation zone (TZ) and squamocolumnar junction (SCJ) vary considerably. We aimed to identify areas of agreement and areas where work is required to standardize the definitions of the TZ and the SCJ. We conducted a survey among the board members of the European Federation of Colposcopy member societies and members of the International Society of Gynecological Pathologists. Overall, 22 expert colposcopists and 34 gynecologic pathologists responded. There was broad agreement that the TZ is the area where squamous metaplasia has occurred. There was consensus that the original SCJ can appear colposcopically indistinct in cases of maturation of the metaplastic squamous epithelium but can be identified histologically by the presence of the so-called last cervical gland. It was agreed that the border between the metaplastic squamous epithelium and the columnar epithelium on the surface of the cervix is called the new SCJ. Areas where work is required include the questions as to whether the cervical crypts lined by columnar epithelium in the field of squamous metaplasia are an integral part of the TZ or not and whether the individual microscopic borders between the metaplastic squamous epithelium of glandular crypts and the residual columnar epithelium of glandular crypts should be considered as part of the new SCJ or not. This paper is a step in an attempt to standardize colposcopic and histologic definitions among colposcopists and pathologists.

RESUMEN

Cervical cancer screening test performance has been hampered by either lack of sensitivity of Pap cytology or lack of specificity of Human Papillomavirus (HPV) testing. This uncertainty can lead to unnecessary referral and treatment, which is disturbing for patients and increases costs for health care providers. The identification of p16(INK4a) as a marker for neoplastic transformation of cervical squamous epithelial cells by HPVs allows the identification of HPV-transformed cells in histopathology or cytopathology specimens. Diagnostic studies have demonstrated that the use of p16(INK4a) immunohistochemistry substantially improves the reproducibility and diagnostic accuracy of histopathologic diagnoses. p16(INK4a) cytology has substantially higher sensitivity for detection of cervical precancer in comparison to conventional Pap tests. Compared to HPV DNA tests, immunochemical detection of p16(INK4a) -stained cells demonstrates a significantly improved specificity with remarkably good sensitivity. About 15 years after the initial observation that p16(INK4a) is overexpressed in HPV-transformed cells we review the accumulated clinical evidence suggesting that p16(INK4a) can serve as a useful biomarker in the routine diagnostic work up of patients with HPV infections and associated lesions of the female anogenital tract.

RESUMEN

AIMS: To report an exceptional case of papillary ependymoma occurring in the endometrium. METHODS AND RESULTS: A clinicopathological study was performed regarding a case of papillary ependymoma occurring in the endometrial cavity of a 61-year-old patient who had presented with a solid-type, stage III anaplastic ependymoma of the ovary, treated with cytoreductive surgery that included total abdominal hysterectomy. The uterus was enlarged and showed a dilated cavity, with broadly implanted papillary excrescences without myometrial invasion that were covered by tall, cylindrical cells. These cells had glial fibrillary acidic protein-expressing cytoplasm that was also positive for cytokeratins 7, 8, 18, and 34ß-E12, epithelial membrane antigen, S100 protein, vimentin, and oestrogen and progesterone receptors. CONCLUSIONS: Pathogenetically, the presence of this uterine ependymoma could represent either an example of multicentricity or a phenomenon of transtubal implantation of the ovarian tumour. Exceptionally, papillary ependymoma can occur in the endometrium, and may prompt differential diagnoses with other papillary endometrial tumours. Pathologists should consider this rare possibility in the differential diagnosis of papillary ovarian and endometrial lesions.

RESUMEN

AIMS: To compare the reproducibility of the current (2003) World Health Organization (WHO), endometrial intraepithelial neoplasia (EIN) and European Working Group (EWG) classifications of endometrial endometrioid proliferations. METHODS AND RESULTS: Nine expert gynaecological pathologists from Europe and North America reviewed 198 endometrial biopsy/curettage specimens originally diagnosed as low-grade lesions. All observers were asked to classify the cases by using the categories described in each scheme: six for WHO, four for EIN, and three for EWG. The results were evaluated by kappa statistics for more than two observations. The analysis was repeated using only two major categories (benign versus atypical/carcinoma). Both the WHO and EIN classifications showed poor interobserver agreement (κ = 0.337 and κ = 0.419, respectively), whereas the EWG classification showed moderate agreement (κ = 0.530). Full agreement between pathologists occurred in only 28% for the WHO classification, 39% for the EIN classification, and 59% for the EWG classification. With only two diagnostic categories, kappa values increased in all classifications, but only the EWG classification reached a substantial level of agreement (κ = 0.621); similarly, full agreement among all pathologists increased to 70% for the WHO classification, 69% for the EIN classification, and 72% for the EWG classification. CONCLUSIONS: A two-tier classification of endometrial endometrioid proliferative lesions improves reproducibility, and should be considered for the diagnosis of endometrial biopsy/curettage specimens.

RESUMEN

Current cytology-based screening has a moderate sensitivity to detect cervical intraepithelial neoplasia grade 3 (CIN 3) and cervical cancer even in those states providing rigorous quality control of their cervical screening programs. The impact of vaccination against human papillomavirus (HPV) types 16 and 18 as well as the incorporation of HPV testing on the detection of CIN 3 and cancer is discussed. HPV testing used as a triage for atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions, test of cure after treatment, and HPV-based primary screening may improve current cervical screening programs.HPV testing as a triage test for ASCUS seems to offer an improved sensitivity, with a similar specificity as compared to repeat cytology for diagnosing high-grade CIN and has been recommended throughout most EU states. HPV testing as a triage test for low-grade squamous intraepithelial lesions has a low specificity and is not recommended in most member states. HPV test of cure offers an improved sensitivity compared to cytology for women with persistent cervical precancer after treatment. HPV-based cervical cancer screening is more effective than screening with cytology. The effects of HPV-based screening depend on the organization of the program and on adherence to algorithms for screening triage. Otherwise, it is likely that HPV-based screening will increase the referral rate to colposcopy including more women with no detectable cervical lesion. HPV vaccination will require many years to evaluate any beneficial effects on cervical cancer incidence and mortality.

RESUMEN

Improvements in the performance of cervical screening may be limited by the diagnostic performance of colposcopy. Nonetheless, colposcopy remains the best available tool to assess women considered at high risk for having or developing cervical cancer. The provision and role of colposcopy across Europe is variable. Introduction of vaccination against human papillomavirus (HPV) types 16 and 18 as well as the possible switch to HPV-based screening is likely to change the profiles of women presenting to colposcopy services and provide management difficulties for the colposcopist.The standard of colposcopy in Europe can be maintained or improved despite a variable availability of screening. The prevalence of cervical intraepithelial neoplasia grade 3 may decrease for women having had HPV vaccination. The incidence of cervical intraepithelial neoplasia grade 3 and cervical cancer in second and subsequent rounds of HPV-based screening are likely to decrease compared to cytology-based screening. In HPV-based screening, the numbers of women with no detectable or minor abnormalities at colposcopy and with screen-detected glandular disease are likely to increase. We have considered how these issues will affect states that have varying implementation of organized cervical screening programs and varying degrees of implementation of HPV testing or vaccination.The development of quality assurance across Europe accompanying these program changes is discussed.

RESUMEN

Ulipristal acetate (UPA) is a novel Progesterone Receptor Modulator (PRM) and registered for the pre-operative treatment of symptomatic uterine fibroids during 3months. In a study which assessed the potential toxicity of UPA in female cynomolgus monkeys following daily oral administration of 1, 5, or 25mg/kg for 39weeks, UPA was well tolerated with dose-dependent macroscopic and microscopic observations limited to the uterus and oviducts. These findings were considered to be related to the pharmacological action of UPA and showed evidence of partial reversibility. Findings in the endometrium were similar to PRM-associated-endometrial-changes (PAEC) described in PRM-treated women. No adverse effects were found that would raise concerns about potential pre-malignancy. Although the translation of these findings to human is limited by the small study size and species differences, these results from animals chronically exposed to up to 150times the clinical UPA exposure are considered significant and supportive to the chronic administration of UPA for more than 3months in women of reproductive age.

RESUMEN

Cervical cancer screening concerns women between the ages of 25 and 65. It consists of the collection of cervical cells with a spatula by rubbing the cervix. The material was initially spread out and fixed on a glass slide. It was subsequently fixed in a liquid preservative with an automated spread on a thin-layer slide after centrifugation or filtration, a process called liquid cytology. Microscopic reading was facilitated by field selection using an automated pre-reading system. In July 2019, the French High Authority for Health (HAS) recommended to position DNA research of high-risk human papillomavirus types by PCR (HPV HR test) in first position after the age of 30. This approach is more sensitive than cytology in diagnosing a histological high-grade squamous intraepithelial lesion, and more effective in preventing invasive cancers. The HPV HR test, if positive, is followed by a cytological examination on the same sample to select patients requiring examination of the cervix by colposcopy. Vaccination against the nine most common types of HPV in girls and boys aged 11 to 14 years is the other part of the prevention of invasive cancer.


Title: La prévention du cancer du col utérin. Abstract: Le dépistage du cancer du col de l'utérus concerne les femmes âgées de 25 à 65 ans. Il consiste à recueillir des cellules en frottant le col utérin avec une spatule. Le matériel biologique prélevé est ensuite déposé directement sur lame ou après l'avoir dilué dans un conservateur et cytocentrifugé (cytologie en milieu liquide). Il est ensuite analysé au microscope. En juillet 2019, la Haute autorité de santé a recommandé de rechercher l'ADN des types de papillomavirus humains (human papillomavirus, HPV) à haut risque ou potentiellement oncogènes, par PCR (test HPV HR), comme première étape du dépistage après l'âge de 30 ans. Ce test est plus sensible que la cytologie pour diagnostiquer une lésion histologique malpighienne intraépithéliale de haut grade, et plus efficace pour prévenir les cancers invasifs. Lorsque ce test est positif, une analyse cytologique sur le même prélèvement est réalisée afin de sélectionner les patientes nécessitant une colposcopie. Le deuxième volet de la prévention du cancer du col utérin repose sur la vaccination. Nous discutons, dans cette revue, l'importance de la détection des lésions du col utérin et le rôle des HPV.

RESUMEN

OBJECTIVES: The primary objective of our study is to investigate the rate of non-contributory biopsies between punch biopsy(PB) and cervical forceps biopsy(CFB) for a vulvar lesion seen in consultation. The secondary objective of our study is to evaluate the rate of underestimation of a more severe lesion for patients who have undergone vulvar excision. MATERIAL AND METHOD: This is a retrospective, descriptive, and comparative study conducted at three centers. The study population consisted of patients who underwent vulvar biopsy between 2017 and 2022 in a gynecological surgery consultation at two French hospitals, as well as a city office. The biopsy techniques used were punch or cervical forceps biopsy. Quantitative variables were analyzed using the Mann-Whitney test, while Pearson's or Fisher's Xi2 tests were used for qualitative variables. The significance level was set at 5%. RESULTS: We conducted a retrospective study of 179 vulvar biopsies, of which 100 were punch biopsies and 79 were cervical forceps biopsies, from a total of 107 patients. There was no significant difference in the rate of non-contributory biopsies between the PB and CB groups (p = 1). When analyzing the secondary endpoint of our study, which included 68 patients who underwent vulvectomy after vulvar biopsy, we found that 66 patients (97%) had a good correlation between the pathology of the vulvar biopsy and that of the vulvectomy specimen. CONCLUSION: Vulvar biopsy techniques using punch or cervical forceps appear to have similar diagnostic performance and are associated with comparable and low rates of underestimation of invasive lesions.

RESUMEN

High-risk human papillomavirus (HPV) DNA/RNA testing provides higher sensitivity but lower specificity than cytology for the identification of high-grade cervical intraepithelial neoplasia (CIN). Several new HPV tests are now available for this purpose, and a direct comparison of their properties is needed. Seven tests were evaluated with samples in liquid PreservCyt transport medium from 1,099 women referred for colposcopy: the Hybrid Capture 2 (Qiagen), Cobas (Roche), PreTect HPV-Proofer (NorChip), Aptima HPV (Gen-Probe), and Abbott RealTime assays, the BD HPV test, and CINtec p16(INK4a) cytology (mtm laboratories) immunocytochemistry. Sensitivity, specificity, and positive predictive value (PPV) were based on the worst histology found on either the biopsy or the treatment specimen after central review. Three hundred fifty-nine women (32.7%) had CIN grade 2+ (CIN2+), with 224 (20.4%) having CIN3+. For detection of CIN2+, Hybrid Capture 2 had 96.3% sensitivity, 19.5% specificity, and 37.4% PPV. Cobas had 95.2% sensitivity, 24.0% specificity, and 37.6% PPV. The BD HPV test had 95.0% sensitivity, 24.2% specificity, and 37.8% PPV. Abbott RealTime had 93.3% sensitivity, 27.3% specificity, and 38.2% PPV. Aptima had 95.3% sensitivity, 28.8% specificity, and 39.3% PPV. PreTect HPV-Proofer had 74.1% sensitivity, 70.8% specificity, and 55.4% PPV. CINtec p16(INK4a) cytology had 85.7% sensitivity, 54.7% specificity, and 49.1% PPV. Cytology of a specimen taken at colposcopy (mild dyskaryosis or worse) had 88.9% sensitivity, 58.1% specificity, and 50.7% PPV. Our study confirms that, in a referral setting, HPV testing by a number of different tests provides high sensitivity for high-grade disease. Further work is needed to confirm these findings in a routine screening setting.
