Abstract
BACKGROUND Cervical cancer is preventable through screening and vaccination against high-risk human papillomavirus (hr-HPV). For a screening program to be successful it is vital that the clinical management and follow-up regime of patients with abnormal screening results is well developed and that the attendance rate for follow-up is high. The aim of the study was to analyze how effective conization with recommended follow-up was in preventing subsequent cervical cancer, and to evaluate how clinical follow-up recommendations are obeyed in the region of Skåne, Sweden. METHODS All women (n = 8835) who had undergone conization in the region of Skåne, Sweden, between the years of 2015 and 2021 were identified. Individuals with confirmed cervical cancer in the conization material were referred for additional treatment (n = 114), leaving 8721 included in the follow-up. Adherence to follow-up and cytological, histopathological and HPV status at follow-up were collected at eight, 12 and 24 months post-conization. The total follow-up time was from January 1, 2015, to January 30, 2023. RESULTS Within 12 months post-conization, 90% of the patients conducted a cytological cervical sample. The rates of a negative test of cure (HPV negative and normal cytology) were 69.7%, 76.3% and 84.4% at eight, 12 and 24 months post-conization respectively. The clearance of HPV was 79.6%, 80.8% and 87.8% at eight, 12 and 24 months post-conization respectively. Out of 5613 patients with a negative test of cure within one year after conization, no cervical cancer was found during follow-up and 11 (0.2%) women developed high-grade intraepithelial lesions/adenocarcinoma in situ (HSIL/AIS) with an average time from conization to new diagnosis of 42 months. The mean follow-up time was 32.1 months. CONCLUSIONS The clearance rate of hr-HPV post cervical conization due to dysplasia appears to be high within eight months. With a negative test of cure post cervical conization, the risk of cervical cancer within the following three years seems to be extremely low and the risk of developing HSIL/AIS was lower than the incidence of HSIL/AIS in the general screening population.

Abstract
OBJECTIVE The aim of this study was to determine the number of patients undergoing large loop excision of the transformation zone (LLETZ), for biopsy-confirmed high-grade squamous intraepithelial lesions (HSIL), where the original cervical screening test (CST) reported oncogenic human papillomavirus (HPV) and negative liquid-based cytology (LBC). This reflects the number of patients where a LLETZ procedure would not have occurred under the previous guideline. METHODS Retrospective observational chart review of all patients (n = 477) who underwent LLETZ procedure in a single tertiary unit over a 36-month period. Prevalence of negative histopathology, positive margins, incidental cervical cancer, and accuracy of HSIL identification at colposcopy were measured. Diagnostic accuracy of HSIL diagnosis from initial colposcopic impression was calculated; factors influencing accuracy were evaluated using multivariable logistic regression analysis. There were no comparators. RESULTS Of 477 LLETZs, 5.9% (n = 28) were for oncogenic HPV and normal LBC on referral CST. Demographics between the "study" (oncogenic HPV and normal LBC on referral CST) and the "standard" group were similar, except the study group was less likely to be using contraception (25% vs 47%, p = .023). In the study group, initial colposcopic cervical biopsy confirmed HSIL in 91.6% (n = 27) and low-grade squamous intraepithelial lesions in 3.6% (n = 1). Histopathological analysis of LLETZ specimens confirmed HSIL in 20 patients (71.4%) and low-grade squamous intraepithelial lesions in 2 (7.1%). No microinvasion was detected. CONCLUSIONS The renewed National Cervical Screening Programme (NCSP), is detecting more "at risk" patients, predicted to lead to a further reduction in incidence of cervical cancer in adequately screened patients.

Evaluation of the clinical efficacy of vaginal treatment options for persistent high-risk human papillomavirus infection after excisional treatment of cervical high-grade squamous intraepithelial lesions: a systematic review and Bayesian network meta-analysis. Virol J 2023; 20:47. [PMID: 36935507 PMCID: PMC10026470 DOI: 10.1186/s12985-023-02001-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Accepted: 02/27/2023] [Indexed: 03/21/2023] Open
Abstract
BACKGROUND To evaluate the clinical efficacy of different vaginal administration on cervical persistent high-risk human papillomavirus (HR-HPV) infection after excisional treatment for high-grade squamous intraepithelial lesions (HSIL). METHODS Six databases (PubMed, EmBase, Cochrane Central, China Knowledge Network database, China Biomedical Literature Service, and WanFang database) were searched to collect randomized controlled trials (RCTs) of various types of vaginal administration compared to no treatment on persistent HR-HPV infection after HSIL excisional treatment, and comprehensive analysis of the clearance of different drugs on HR-HPV was performed using Bayesian reticulation meta-analysis. RESULTS The study analyzed the efficacy of eight interventions, including Interferon, Baofukang, Paiteling, Bletilla striata Sanhuang Powder, Lactobacilli vaginal capsules, Fuanning + Interferon, Interferon + Lactobacilli vaginal capsules, and Interferon + Baofukang, on the clearance of HR-HPV after excisional treatment through pooling and analyzing data from 52 RCTs. The results of the study demonstrated that Interferon + Lactobacilli vaginal capsules [OR 16.0 (95% CIs 8.1-32.0)], Interferon + Fuanning [OR 16.0 (95% CIs 1.1-52.0)], and Interferon + Baofukang [OR 14.0 (95% CIs 6.8-28.0)] were all found to significantly improve postoperative HR-HPV clearance rates when compared to no treatment. Furthermore, when studies with high-risk bias were excluded, Interferon + Lactobacilli vaginal capsules [OR 8.6 (95% CIs 4.7-19.0)] and Interferon + Baofukang [OR 22.0 (95% CIs 8.7-59.0)] were still found to be positively associated with increased postoperative HR-HPV clearance rate. Additionally, the study´s results also indicate that Interferon + Baofukang was effective in enhancing the postoperative HR-HPV clearance rates, mainly when the studies were restricted to a follow-up period of at least 12 months [OR 9.6 (95% CIs 2.9-34.0)]. However, it is important to note that the majority of the trials (29 out of 52, 51.6%) were rated as moderate to high risk of bias, and the certainty of the evidence was moderate to very low. CONCLUSION The application of various forms of vaginal administration, except for individual use of Lactobacilli vaginal capsules, is more efficacious than no treatment in patients with cervical persistent HR-HPV infection after excisional treatment. However, all of the estimates of the effect size for change in the efficiency of HR-HPV clearance are uncertain. Our confidence in effect estimates and ranking of treatments is low, which needs larger, more rigorous, and longer follow-up RCTs to resolve.

Abstract
The clinical performance evaluation of the novel MassARRAY human papillomavirus (MA-HPV) assay was performed using Danish SurePath cervical cancer screening samples under the fourth Validation of HPV Genotyping Tests (VALGENT) framework. The MA-HPV assay is a mass array-based assay that individually detects 14 oncogenic HPV genotypes and five nononcogenic types. The MA-HPV assay was validated using the VALGENT4 panel, which constitutes 997 consecutive samples from a screening population in addition to 297 disease-enriched samples with abnormal cytology findings. The clinical accuracy of the MA-HPV assay for sensitivity and specificity was assessed relative to that of the general primer 5+/6+ PCR enzyme immunoassay (GP-EIA), by a noninferiority test. The type-specific concordance of the MA-HPV assay was assessed as well. The relative sensitivity of the MA-HPV assay for cervical intraepithelial neoplasia ≥2 or ≥3 was 1.02 (95% CI, 0.98-1.05) and 1.01 (95% CI, 0.99-1.04), respectively. The sensitivity of the MA-HPV was noninferior to that of the GP-EIA (P = 0.0001), whereas the specificity of the MA-HPV was inferior (0.89; 95% CI, 0.85-0.91; P > 0.99). The MA-HPV assay is a clinical sensitive assay with a lower clinical specificity compared with the GP-EIA. The assay in its current form seems more suited to play a role where specificity is of lesser importance but where high sensitivity is paramount.

Abstract
OBJECTIVE To evaluate the efficacy and superiority of loop electrosurgical excision procedure (LEEP) in managing stage IA1 cervical microinvasive squamous cell carcinoma (MISCC) without lymph-vascular space invasion (LVSI). MATERIALS AND METHODS The oncological and reproductive outcomes of a series of patients affected by stage IA1 MISCC without LVSI, initially treated by LEEP between February 2006 and December 2017, were retrospectively reviewed. RESULTS Ultimately, 109 patients were included. The mean age at diagnosis was 35.4 years old, and 36 patients were nulliparous. Multifocal lesions were identified in 15 patients (13.8%). The mean cone depth was 17.4 mm. Resection margins were positive/unevaluable and negative in 26 (23.9%) and 83 (76.1%) cases, respectively. Among cases undergoing salvage treatments, the residual disease rate for patients with positive/unevaluable margins was significantly higher than those with negative margins (P = 0.003). During the follow-up period of 43.0 ± 28.9 months, no relapse was identified. Fifteen of 20 patients (75.0%) conceived successfully, with a full-term live birth rate of 93.3%. CONCLUSIONS For stage IA1 MISCC without LVSI unexpectedly found in a loop excision, initial LEEP with clear margin is efficient and adequate. For cases with multifocal MISCC, or for those young patients who wish to become pregnant in the future, LEEP is the optimal choice.

Abstract
OBJECTIVES The aims of the study were to investigate how many women after 1 or 2 follow-up examinations, based on combined cervical cytology and human papillomavirus (HPV) testing, could finish posttreatment follow-up and continue with the general screening program and to determine the 5-year risk of recurrence in this group. METHODS This is a prospective observational study that includes women, who underwent loop electrosurgical excision procedure (LEEP) in the North Denmark Region, from January 1, 2012, to May 31, 2014. All included women had histologically verified diagnosis of high-grade cervical intraepithelial neoplasia (CIN 2+) or adenocarcinoma in situ (AIS) before LEEP and posttreatment follow-up with cervical cytology and HPV combination testing. Study period was until October 2019. RESULTS Totally, 563 women were included in the study. After finishing the posttreatment follow-up, 439 (78%) could continue to the general screening program and 362 of them had a screening during the study period. Six women (1.7%) had either cervical dysplasia and/or HPV infection in the cervical screening, and of these, 3 (0.8%) had high-grade dysplasia corresponding to CIN 2. None was diagnosed with CIN 3, AIS, or invasive carcinoma. One hundred twenty-one women (36%) chose to be screened sooner than recommended in the national guidelines. CONCLUSIONS Human papillomavirus and cytology combination test after LEEP allows women, irrespective of margin status, safely to continue with the general screening program after a short posttreatment follow-up period. Improved information is mandatory to reduce "opportunistic" screening after finishing posttreatment follow-up.

Abstract
Women treated for high-grade cervical-intraepithelial-neoplasia (CIN) require long-term follow-up with high-risk human-papillomavirus (HPV) testing. Self-sampling for HPV is well-accepted among these patients, but its role in follow-up for this group requires investigation. The present study examined how well HPV findings from self-sampled vaginal (VSS) and urine specimens correctly identified women from this cohort with recurrent CIN2+ compared with samples collected by clinicians. At 1st post-conization follow-up, 531 patients (99.8% participation) gave urine samples, performed VSS, underwent colposcopy with punch biopsy of visible lesions and clinician-collected cervical sampling for HPV analysis and liquid-based cytology. A total of 113 patients with positive HPV and/or abnormal cytology at 1st follow-up underwent 2nd follow-up. At 1st follow-up, all patients with recurrent CIN3 had positive HPV results by all methods. Clinician sampling and VSS revealed HPV16 positivity in 50% of recurrent cases and urine sampling revealed HPV16 positivity in 25% of recurrent cases. At 2nd follow-up, all 7 newly-detected CIN2/3 recurrences were associated with HPV positivity on VSS and clinician-samples. Only clinician-collected samples detected HPV positivity for two adenocarcinoma-in-situ recurrences, and both were HPV18 positive. A total of 77 patients had abnormal cytology at 1st follow-up, for which HPV positivity via VSS yielded highest sensitivity. The HPV findings were positive from VSS in 12 patients with high-grade squamous-intraepithelial-lesions (HSIL), and 11 patients with HSIL had positive HPV findings in clinician-collected and urine samples. All methods for assessing HPV presence yielded significant age-adjusted odds ratios for predicting abnormal lesions at 1st follow-up. For overall HPV results, Cohen's kappa revealed substantial agreement between VSS and clinician sampling, and moderate agreement between urine and clinician sampling. Clinician sampling and VSS were highly concordant for HPV16. Insofar as the pathology was squamous (not glandular), VSS appeared as sensitive as clinician sampling for HPV in predicting outcome among the present cohort. Since VSS can be performed at home, this option can maximize participation in the required long-term follow-up for these women at high-risk.

Abstract
BACKGROUND Human papillomavirus (HPV) testing is recommended in primary cervical screening to improve cancer prevention. An advantage of HPV testing is that it can be performed on self-samples, which could increase population coverage and result in a more efficient strategy to identify women at risk of developing cervical cancer. Our objective was to assess whether repeated self-sampling for HPV testing is cost-effective in comparison with Pap smear cytology for detection of cervical intraepithelial neoplasia grade 2 or more (CIN2+) in increasing participation rate in primary cervical screening. METHODS A cost-effectiveness analysis (CEA) was performed on data from a previously published randomized clinical study including 36,390 women aged 30-49 years. Participants were randomized either to perform repeated self-sampling of vaginal fluid for HPV testing (n = 17,997, HPV self-sampling arm) or to midwife-collected Pap smears for cytological analysis (n = 18,393, Pap smear arm). RESULTS Self-sampling for HPV testing led to 1633 more screened women and 107 more histologically diagnosed CIN2+ at a lower cost vs. midwife-collected Pap smears (€ 229,446 vs. € 782,772). CONCLUSIONS This study resulted in that repeated self-sampling for HPV testing increased participation and detection of CIN2+ at a lower cost than midwife-collected Pap smears in primary cervical screening. Offering women a home-based self-sampling may therefore be a more cost-effective alternative than clinic-based screening. TRIAL REGISTRATION Not registered since this trial is a secondary analysis of an earlier published study (Gustavsson et al., British journal of cancer. 118:896-904, 2018).

Role of Colposcopy after Treatment for Cervical Intraepithelial Neoplasia. Cancers (Basel) 2020; 12:cancers12061683.

Abstract
Colposcopy is often used in follow-up after treatment for cervical intraepithelial neoplasia (CIN) despite its marked inter-observer variability and low sensitivity. Our objective was to assess the role of colposcopy in post-treatment follow-up in comparison to hrHPV (high-risk human papillomavirus) testing, cytology, and cone margin status. Altogether, 419 women treated for histological high-grade lesion (HSIL) with large loop excision of the transformation zone (LLETZ) attended colposcopy with cytology and hrHPV test at six months. Follow-up for recurrence of HSIL continued for 24 months. Colposcopy was considered positive if colposcopic impression was recorded as high grade and cytology if HSIL, ASC-H (atypical squamous cells, cannot exclude HSIL), or AGC-FN (atypical glandular cells, favor neoplasia) were present. Overall, 10 (10/419, 2.4%) recurrent HSIL cases were detected, 5 at 6 months and 5 at 12 months. Colposcopic impression was recorded at 407/419 6-month visits and was positive for 11/407 (2.7%). None of them had recurrent lesions, resulting in 0% sensitivity and 97% specificity for colposcopy. Sensitivity for the hrHPV test at 6 months was 100% and specificity 85%, for cytology 40% and 99%, and for margin status at treatment 60% and 82%, respectively. While the hrHPV test is highly sensitive in predicting recurrence after local treatment for CIN, colposcopy in an unselected population is not useful in follow-up after treatment of CIN.

Abstract
OBJECTIVE To establish the clearance of cervical human papillomavirus (HPV) infection following postoperative immunotherapy with inosine pranobex in women receiving surgical treatment of established high-grade squamous intraepithelial lesion (HSIL) of the uterine cervix. MATERIALS AND METHODS Over the six-year study period, 32 women with cervical HPV infection following electroconization (loop electrosurgical excision procedure) of the uterine cervix for established HSIL were randomly divided into two groups: I (n = 10) without and II (n = 22) with postoperative inosine pranobex immunotherapy. Follow-up after 24 and 48 months included cervical testing for HPV persistence and after 12, 24, and 48 months with cytology and colposcopy for dysplasia relapse (confirmed histologically). RESULTS Relapse monitoring in 32 women after 12 months revealed 1 and 0 HSIL positive in groups I and II, respectively; after 24 months an additional 3 patients in each group were positive; and after 48 months an additional 3 and 1 patients were positive in groups I and II, respectively (p < .05). The groups significantly differed (p < .05) with regard to clearing the most common high-risk HPV genotypes (HPV 16 and HPV 56). CONCLUSIONS Inosine pranobex immunotherapy in HPV-positive patients following cervical conization significantly increased the clearance of viral infection with high-risk genotypes and reduced relapse of HSIL.

Abstract
OBJECTIVE To evaluate adherence to national guidelines for follow-up, and assess residual and recurrent disease after treatment for cervical intraepithelial neoplasia grade 2 or worse (CIN2+). STUDY DESIGN In a case-series design women aged 25-69 years treated for primary CIN2+ in 2006-2011 (n = 752) were followed through August 9, 2019 for residual or recurrent disease, i.e., CIN2+ diagnosed before or after, respectively, two consecutive, normal post-treatment cytology results. We used the Chi-Square test to assess predictive factors of adherence to post-treatment follow-up and residual disease, and survival analyses to assess the cumulative incidence of residual and recurrent disease. RESULTS Strict adherence to post-treatment follow-up was low . However, 702 (95 %) women attended at least one post-treatment follow-up visit within the suggested time window. Forty-two women (5.6%) were diagnosed with residual disease, 38 (91 %) of whom were diagnosed within 2 years of treatment. Among the 637 (85 %) women with two consecutive, normal post-treatment cytology results, cumulative incidence of recurrent disease was 1.0 (95 % confidence interval [CI]: 0.2-1.8) and 2.5 (95 % CI: 1.2-3.8) per 100 women-years within 42 and 78 months of treatment, respectively. Three women with residual and two with recurrent disease were diagnosed with cervical cancer within 78 months of treatment. Women with not-free resection margins at treatment had a significantly increased risk of residual and recurrent disease. Using a 2-year definition for residual disease would misclassify 3 of 5 cancer cases as recurrent disease when they were true cases of residual disease. CONCLUSIONS This study emphasizes the importance of properly distinguishing between residual and recurrent disease after treatment for CIN2 + . Many women with residual disease could benefit from an earlier colposcopy, cervical biopsy, or diagnostic conization during post-treatment follow-up in order to detect occult cervical cancer. The cumulative incidence of recurrent disease within 78 months of treatment was low.

A randomized trial comparing limited-excision conisation to Large Loop Excision of the Transformation Zone (LLETZ) in cervical dysplasia patients. J Gynecol Oncol 2019; 30:e42. [PMID: 30887760 PMCID: PMC6424847 DOI: 10.3802/jgo.2019.30.e42] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2018] [Revised: 11/21/2018] [Accepted: 11/28/2018] [Indexed: 11/30/2022] Open
Abstract
Objective To show noninferiority of a limited-excision (resection of the dysplastic lesion only) vs. classical Large Loop Excision of the Transformation Zone (LLETZ). Methods In this prospective, randomized, multicenter trial, women with human papillomavirus (HPV) positive cervical intraepithelial neoplasia grade 3 were randomized into two groups (1:1). Primary outcome was the rate of negative HPV tests after 6 months, secondary outcomes included cone size, complete resection rates as well as cytological and histological results after 6 and 12 months. A sample size of 1,000 was calculated to show noninferiority of the limited-excision compared to the LLETZ group using a noninferiority margin of 5%. Enrollment was stopped after 100 patients due to slow accrual. Results Patients in the limited-excision group did not show a lower number of negative HPV tests (78% [LLETZ]−80% [limited-excision]=−2%; 90% confidence interval=−15%, 12%). The limited-excision resulted in a substantially lower cone size (LLETZ: 1.97 mL vs. limited-excision: 1.02 mL; p<0.001) but higher numbers of involved margins (LLETZ: 8% vs. limited-excision: 20%). Although postoperative cytological results slightly differed, histological results were similar in both groups. One limited-excision patient received immediate re-conisation, whereas one patient in each group was scheduled for re-conisation after 6 months. Conclusion The limited-excision could represent a promising option to reduce the surgical extent of conisations while maintaining oncological safety. The trial was not sufficiently powered to reach statistical significance due to early termination. Nevertheless, the study provides important insights in the feasibility of a limited-excision and could serve as a pilot study for future trials.

Role of HPV DNA, HPV mRNA and cytology in the follow-up of women treated for cervical dysplasia. APMIS 2019; 127:196-201. [PMID: 30815926 DOI: 10.1111/apm.12931] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Accepted: 01/08/2019] [Indexed: 01/03/2023]
Abstract
The aim of this study was to assess the role of cytology, human papilloma virus (HPV) DNA and human papilloma virus messenger RNA (HPV mRNA) assays in detecting cervical intraepithelial neoplasia grade 2+ (CNi 2+) (recurrences/persistence) during the follow-up of women after treatment of cervical intraepithelial lesion. This cross-sectional study was performed among 43 women treated for cervical intraepithelial neoplasia (CIN) between January 2014 and January 2017 at the Department of Obstetrics and Gynecology of Spedali Civili's Hospital, Brescia, Italy. Pap smear and cervical samples for HPV tests were collected during the follow-up visit. Furthermore, colposcopy was always performed in order to find out the persistence/recurrence of the disease. A cervical biopsy was collected when necessary. Cervical samples obtained were tested for HPV DNA using the INNO-LiPa HPV assay and for HPV mRNA using the APTIMA assay. The mean age of enrolled women was 42.5 years. Among the treated patients, more than 50% of women revealed the absence of high risk HPV DNA and HPV mRNA. We found the persistence of the disease cervical intraepithelial neoplasia grade 2 (CIN 2) only in one woman. The sensitivity of cytology, HPV DNA and HPV mRNA in detecting disease was satisfactory (100%), while the specificity was quite different for the three tests: 64.2, 52.4 and 78.9%, respectively. The HPV mRNA test has higher specificity with respect to cytology and HPV DNA, avoiding the referral to unnecessary colposcopy with an improvement of costs/benefits for healthcare system. However, given the small size sample, this study should be considered as a pilot for future larger studies.

Abstract
Cervical cancer is the fourth most frequently occurring cancer in women around the world and can affect them during their reproductive years. Since the development of the Papanicolaou (Pap) test, screening has been essential in identifying cervical cancer at a treatable stage. With the identification of the human papillomavirus (HPV) as the causative agent of essentially all cervical cancer cases, HPV molecular screening tests and HPV vaccines for primary prevention against the virus have been developed. Accordingly, comparative studies were designed to assess the performance of cervical cancer screening methods in order to devise the best screening strategy possible. This review critically assesses the current cervical cancer screening methods as well as the implementation of HPV vaccination in Europe. The most recent European Guidelines and recommendations for organized population-based programs with HPV testing as the primary screening method are also presented. Lastly, the current landscape of cervical cancer screening programs is assessed for both European Union member states and some associated countries, in regard to the transition towards population-based screening programs with primary HPV testing.

Abstract
Objective Self-sampling to test for high risk human papilloma virus (HPV) is becoming an increasingly important component of cervical cancer screening. The aim of this observational study is to examine how women treated for high-grade cervical intraepithelial neoplasia (CIN) view HPV self-sampling. Methods Invited to participate in the present study were patients who had undergone treatment of high-grade CIN (grade 2 or higher) and were followed-up at 6-months at the Karolinska University Hospital, Stockholm. The participants were instructed as to how to perform HPV self-sampling. Thereafter, the participants completed a questionnaire about HPV self-sampling and other cervical cancer screening methods, as well as about self-perceived risk of cervical cancer without regular gynecologic follow-up and about specific knowledge regarding HPV, CIN and cervical cancer. Results Altogether 479 women enrolled in this study. The participation rate was 96.6%. Nearly 75% of the participants stated they would consider performing the HPV self-sampling prior to their next gynecologic follow-up. Confidence in HPV self-sampling was a significant independent predictor of willingness to perform HPV self-sampling. However, confidence in HPV self-sampling was significantly lower than confidence in Papanicolaou smears and in HPV testing with samples collected by health professionals. Higher specific knowledge about HPV, CIN and cervical cancer was also a significant independent predictor of willingness to perform HPV self-sampling, as was having travelled longer distance to attend gynecologic follow-up. Participants with lower income and without completed university education expressed significantly higher confidence in HPV self-sampling and lower confidence in Papanicolaou smears than the other women. Conclusions To the best of our knowledge, this is the first study to examine the views of women treated for high-grade CIN vis-à-vis HPV self-sampling. The latter is an acceptable option for the vast majority of this cohort of women.

Abstract
INTRODUCTION The purpose of this study was to determine the feasibility of human Papillomavirus (HPV) testing alone as a prognostic tool to predict recurrent disease within a three-year follow-up period after treatment for cervical intraepithelial neoplasia (CIN)2+ . MATERIAL AND METHODS Retrospectively, 128 women with histologically verified CIN2+ who had a conization performed at Southern Jutland Hospital in Denmark between 1 January 2013 and 31 December 2013 were included. Histology, cytology and HPV test results were obtained for a three-year follow-up period. RESULTS 4.7% (6/128) of the cases developed recurrent disease during follow-up. Of the cases without free margins, recurrent dysplasia was detected normal in 10.4% (5/48), whereas in the group with free margins it was 1.3% (1/80). The post-conization HPV test was negative in 67.2% (86/128) and Pap smear normal in 93.7% (120/128). Combining resection margins, cytology and HPV had sensitivity for prediction of recurrent dysplasia of 100%. Specificity was 45.8%, positive predictive value (PPV) 8.5% and negative predictive value (NPV) 100%. Using HPV test alone as a predictor of recurrent dysplasia gave a sensitivity of 83.3%, specificity 69.7%, PPV 11.9% and NPV 98.8%. Combining resection margin and HPV test had a sensitivity of 100%, specificity 45.9%, PPV 8.3% and NPV 100%. CONCLUSION HPV test at six months control post-conization gave an NPV of 98.8% and can be used as a solitary test to identify women at risk for recurrent disease three years after treatment for precursor lesions. Using both resection margin and HPV test had a sensitivity of 100% and NPV 100%. Adding cytology did not increase the predictive value.

Abstract
OBJECTIVE The aim of this study was to evaluate the prognosis and recurrence of microinvasive squamous cervical (MIC) cancer stage IA1 in women treated conservatively or by hysterectomy, and followed-up to 20 years. METHODS It was studied in a cohort of 139 women with MIC, 41 definitively managed by conization and 98 by hysterectomy from January 1994 to December 2003 and followed-up until 2013. The definitive treatment, age, conization technique (loop electrosurgical excision procedure or cold knife conization), cone margin, residual disease in hysterectomy specimen, and the association with recurrence (intraepithelial cervical neoplasia grade 3/intraepithelial vaginal neoplasia grade 3 or worse, and microinvasive or worse) were analyzed. RESULTS There were 2.5 times more conservative treatment in younger women than older (>40 years), and high proportion of residual disease in hysterectomy specimens (67% of intraepithelial cervical neoplasia grade 3 or worse), more common if positive cone margin (74% vs 35%, P < 0.002). There were 2.3% (3/133) recurrences detected as microinvasive or worse, and 6% (8/133) recurrences detected as intraepithelial cervical neoplasia grade 3/intraepithelial vaginal neoplasia grade 3 or worse: 7.3% (3/41) in the conization group and 5.4% (5/92) in the hysterectomy group (P = 0.701). Almost all recurrences (88%, 7/8) were diagnosed until 36 months after treatment, and they were not associated with conization technique. There were no differences in risk of recurrence and overall disease-free survival time related to type of treatment. CONCLUSIONS This study demonstrates the good prognosis of MIC, regardless the treatment. When fertility is not a concern, hysterectomy should be considered as definitive treatment to avoid the risk of residual disease. Regular follow-up for a long period should be maintained.

Abstract
Objective Women with high-grade cervical intraepithelial neoplasia (CIN) are at increased risk for developing cervical cancer. We examine how women with high-grade CIN perceive their own risk, and about pertinent knowledge concerning human high-risk papillomavirus (HPV), CIN and cervical cancer. Methods All patients who underwent first-time treatment of high-grade CIN (grade 2+) were followed-up at 6-months at the Karolinska University Hospital, Stockholm, Sweden and were invited to participate in the present study. This included completion of a questionnaire examining sociodemographic characteristics, self-perceived risk of cervical cancer without regular gynecologic follow-up, and 14 queries about HPV, CIN and cervical cancer knowledge, inter alia. Results The participation rate was 96.6%, with 479 women enrolled in this study. Over 75% were age 40 or younger, over half had completed university education. Most were married or co-living with their partner and were gainfully employed. On a scale scored from 10 (highest self-perceived risk of cervical cancer without regular gynecologic follow-up) to 1 (lowest self-perceived risk), 64% rated their risk ≥ 7; almost 30% viewed their risk ≤ 6 and 7.5% did not rate their risk. A Specific Knowledge Scale with six of the queries explained 58.3% of the total variance. Nearly 30% of the women answered four or fewer of the six queries correctly. The Specific Knowledge Scale predicted self-perceived cervical cancer risk (Odds ratio = 11.3, 95% Confidence Interval 5.6 − 22.6) after adjusting for age, income and education. Most of the women with low self-perceived cervical cancer risk did not rate their HPV-related knowledge as good. However, 32 predominantly university-educated women, with low self-perceived cervical cancer risk, considered their HPV-related knowledge good. Conclusion It is vital to effectively convey accurate information about these patients’ cervical cancer risk, needed preventive and follow-up measures, together with the relevant specific knowledge, for these women at increased risk for developing cervical cancer. Tailored programming to address these knowledge gaps is needed.

Abstract
BACKGROUND To monitor residual disease after treatment of high grade cervical intraepithelial neoplasia (CIN), cytology together with human papillomavirus (HPV) testing are commonly performed. OBJECTIVES To analyse the spectrum of HPV types before and after treatment. STUDY DESIGN This register-based study included 446 women treated for CIN2 or 3, where cytology samples had been HPV-tested before and after treatment by the use of the MGP-PCR Luminex HPV L1-DNA-assay identifying 39 HPV types, including 12 high risk (HR) HPV types. RESULTS Before and after treatment, 706 and 248 HPV isolates were detected of 36 and 34 different HPV types, respectively. Among all the HR HPV isolates, type-specific persistency was observed among 14% (76/542) after treatment, compared to 34% (31/92) of low-risk (LR) HPV isolates (p<0.001). Among the potential high risk (PHR) HPV isolates, 8.3% (6/72) persisted. Totally, 99% (440/446) and 40% (179/446) of the women were HPV-positive before and after treatment, respectively. At least one of the 12 HR HPV types was present in 91% (404/446) and 24% (109/446) of the women before and after treatment, respectively (p<0.0001). HR HPV types were present both before and after treatment among 23% (102/446) of the women, and 16% (71/446) manifested at least one persistent HR HPV type. The sensitivity, specificity and negative predictive value of HR HPV testing for detection of residual high grade squamous intraepithelial lesion (HSIL) was based on the first cytology after treatment, and was 91.7% (95% CI: 61.5%-99.8%), 84.1% (95% CI: 80.0%-87.7%) and 99.7% (95% CI: 98.2%-100.0%), respectively. CONCLUSIONS About one out six treated women (16%) manifested at least one persistent HR HPV type, that was associated with recurrent or residual HSIL disease (odds ratio 58.1, 95% CI 7.4-457) (p=0.0001). Testing for HR HPV demonstrated high sensitivity (92%) for residual HSIL. The higher persistency rate of LR HPV types suggests that they are more likely to be outside the treated area.
