Ultrasound Control of Cervical Regeneration after Large Loop Excision of the Transformation Zone: Results of an Innovative Measurement Technique. Diagnostics (Basel) 2023; 13:diagnostics13040791. [PMID: 36832279 PMCID: PMC9955376 DOI: 10.3390/diagnostics13040791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 02/05/2023] [Accepted: 02/17/2023] [Indexed: 02/22/2023] Open
Abstract
The objective of this research is to evaluate cervical regeneration after large loop excision of the transformation zone (LLETZ) through the identification of a new sonographic reference point at the level of the uterine margins. In the period March 2021-January 2022, a total of 42 patients affected by CIN 2-3 were treated with LLETZ at the University Hospital of Bari (Italy). Before performing LLETZ, cervical length and volume were measured with trans-vaginal 3D ultrasound. From the multiplanar images, the cervical volume was obtained using the Virtual Organ Computer-aided AnaLysis (VOCAL™) program with manual contour mode. The line that connects the points where the common trunk of the uterine arteries reaches the uterus splitting into the ascending major branch and the cervical branch was considered as the upper limit of the cervical canal. From the acquired 3D volume, the length and the volume of the cervix were measured between this line and the external uterine os. Immediately after LLETZ, the removed cone was measured using Vernier's caliper, and before fixation in formalin, the volume of the excised tissue was evaluated by the fluid displacement technique based on the Archimedes principle. The proportion of excised cervical volume was 25.50 ± 17.43%. The volume and the height of the excised cone were 1.61 ± 0.82 mL and 9.65 ± 2.49 mm corresponding to 14.74 ± 11.91% and 36.26 ± 15.49% of baseline values, respectively. The volume and length of the residual cervix were also assessed using 3D ultrasound up to the sixth month after excision. At 6 weeks, about 50% of cases reported an unchanged or lower cervical volume compared to the baseline pre-LLETZ values. The average percentage of volume regeneration in examined patients was equal to 9.77 ± 55.33%. In the same period, the cervical length regeneration rate was 69.41 ± 14.8%. Three months after LLETZ, a volume regeneration rate of 41.36 ± 28.31% was found. For the length, an average regeneration rate of 82.48 ± 15.25% was calculated. Finally, at 6 months, the percentage of regeneration of the excised volume was 90.99 ± 34.91%. The regrowth percentage of the cervical length was 91.07 ± 8.03%. The cervix measurement technique that we have proposed has the advantage of identifying an unequivocal reference point in 3D cervical measurement. Ultrasound 3D evaluation could be useful in the clinical practice to evaluate the cervical tissue deficit and express the "potential of cervical regeneration" as well as provide the surgeon useful information about the cervical length.

Abstract
Introduction. This study aimed to determine whether endocervical glandular involvement by squamous intraepithelial lesion would differ with respect to the depth of the excised specimen and analyze the related factors that may define endocervical glandular involvement among cases treated with cone biopsy. Methods. Between April 2016 and December 2018, women who underwent colposcopy and excisional procedures in the department of gynecologic oncology were retrospectively investigated. Patients with multiple specimens, or whose specimen depths were not measured, and a negative/unknown HPV status were excluded from the study. Also, patients with no dysplasia or microinvasive/invasive cancer in the final pathology report and those who had not undergone endocervical curettage during colposcopy were excluded. HPV genotypes, degree of dysplasia, surgical margin status, and specimen depth were documented from medical records. Further, the association of these factors with endocervical glandular involvement was evaluated. Results: A total of 321 patients who fulfilled the criteria were included in the study, with a mean age of 41.9 years. In total, 101 patients (31.5%) had endocervical glandular involvement. The mean excised specimen depth was 17.04 mm; 17.9 and 16.7 mm for the positive and negative glandular involvement groups, respectively (p = .13). The mean ages were 42.7 and 41.6 years for these groups, respectively (p = .32). There was no association between the HPV genotypes and glandular involvement. Conclusions: Endocervical glandular involvement is not associated with the depth of the excised specimen. A deeper cone biopsy may not necessarily enable a more effective treatment of the disease.

Abstract
ObjectiveThe purpose of this study was to explore the association of cervical disorders on obstetric outcomes of singleton pregnancies in China.MethodsThis hospital-based retrospective cohort study of women with live singleton births included 71,097 Chinese women. We compared the risk of adverse obstetric outcomes in different types of pregnancies with cervical disorders with those with normal cervix. Logistic regression model was used to estimate the association between cervical disorders and adverse obstetric outcomes.ResultsWomen with cervical disorders had a higher risk of premature delivery (10.98 vs. 4.41%), preterm premature rupture of membranes (PPROM) (3.48 vs. 1.62%), low birth weight (LBW) (7.62 vs. 2.92%) and very low birth weight (VLBW) (2.01 vs. 0.28%) than women with normal cervix. After adjusting for confounding factors, compared with women with normal cervix, women with high-grade abnormal cervical cytology are at greater risk of premature birth (adjusted OR 1.971, 95% CI: 1.302–2.983), premature rupture of membranes (PROM) (adjusted OR 1.379, 95% CI: 1.047–1.815), LBW (adjusted OR 1.790, 95% CI: 1.059–3.025), and VLBW (adjusted OR 4.519, 95% CI: 1.662–12.292) than women with low-grade abnormal cervical cytology, and women with abnormal cervical cytology after treatment had a higher risk of premature birth (adjusted OR 2.060, 95% CI: 1.348–3.147), PROM (adjusted OR 1.381, 95% CI: 1.038–1.839), PPROM (adjusted OR 1.995, 95% CI: 1.022–3.892), LBW (adjusted OR 1.801, 95% CI: 1.046–3.102), and VLBW (adjusted OR 4.868, 95% CI: 1.788–13.255) than untreated women.ConclusionsOur research showed that pregnant women with cervical disorders were more likely to have premature delivery, PPROM, LBW, and VLBW. Moreover, pregnant women with high-grade abnormal cervical cytology and abnormal cervical cytology after treatment had a higher risk of premature birth, PROM, LBW, and VLBW.

Associations between cervical intraepithelial neoplasia during pregnancy, previous excisional treatment, cone-length and preterm delivery: a register-based study from western Sweden. BMC Med 2022; 20:61. [PMID: 35189872 PMCID: PMC8862518 DOI: 10.1186/s12916-022-02276-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Accepted: 01/24/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Excisional treatment of cervical intraepithelial neoplasia (CIN) has been associated with increased risk of preterm delivery (PTD), although the underlying mechanism is as yet unclear. Studies on formalin-fixed excised tissue indicate that the risk increases with cone-length, but the magnitude of increase is uncertain, especially in case of minor excisions (≤10 mm), as well compared to women with untreated CIN during pregnancy. This study assesses the impact of cone-length at previous treatment for CIN as well as diagnosis of CIN during pregnancy on the risk of PTD. METHODS A register-based cohort study in western Sweden linking cervical cytology, histology, and treatment data from the Swedish National Cervical Screening Registry to data on obstetric outcomes in singleton pregnancies 2008-2016 from the Swedish Medical Birth Registry. These groups were compared for PTD and other obstetric outcomes: (1) women with one excisional treatment (n=3250, including a subgroup (n=2408) with cone-length measured before fixation; (2) women with untreated CIN diagnosed during pregnancy (n=1380); and (3) women with normal cytology (n=42,398). Logistic regression analyses were adjusted for socioeconomic and health-related confounders. RESULTS Treated women had increased risk of PTD (adjusted odds ratio (aOR) 1.60, 95% confidence interval (CI) 1.21-2.12), spontaneous PTD (aOR 1.95, 95% CI 1.40-2.72) and preterm prelabor rupture of membranes (pPROM) (aOR 2.74, 95% CI 1.66-4.51) compared to the CIN during pregnancy group. ORs were similar when compared to the normal cytology group. Risks of these outcomes increased with cone-length. Mean cone-length was 9.1 mm. Cone-length ≤10 mm was associated with increased risk of PTD (aOR 1.41, 95% CI 1.02-1.94), spontaneous PTD (aOR 1.73, 95% CI 1.18-2.54), and pPROM (aOR 2.44, 95% CI 1.40-4.28), compared to the CIN during pregnancy group. The PTD risk was similar for cone-lengths 3-10 mm, thereafter increasing by 15% with each additional millimeter. CONCLUSIONS This study suggests that all excisional treatment, including small cones, are associated with increased risk of PTD and pPROM. Risks increase further with cone-length. In women of reproductive age, clinicians should aim to remove all CIN but minimal healthy cervical tissue. Cone-length should be recorded at treatment, for future prenatal risk estimation.

Abstract
Cold coagulation of the cervix for cervical intraepithelial neoplasia (CIN), when compared with cervical excision, has previously demonstrated comparable cure rates and a reduction in the rate of spontaneous preterm birth. In the present report the healing pattern in the cervices of two women after cold coagulation is described. Both women underwent cold coagulation due to CIN3, which was found on pre-treatment cervical punch biopsies. They were followed up after cold coagulation and at 7 and 18 months, respectively, they underwent cervical excision. The histopathological slides from the excised specimen were reviewed, which represents the healed cervix after cold coagulation. A clear boundary of collagenisation was noted in the superficial stroma, which appeared to stop at the junction with the healthy muscular stroma. The collagenised superficial stroma depth, which represents the area that was thermally ablated and has now healed, measured 1.6 and 1.5 mm for the two women, respectively, which is less compared with that typically removed by cervical excision. Observations from these two cases indicate that cold coagulation does not appear to disrupt the deep tissue architecture of the cervix and could therefore explain the reduced levels of adverse obstetric morbidity in patients who underwent cold coagulation ablative treatment of the cervix, which has been previously reported.

Abstract
BACKGROUND Vaginal microbiota (VMB) composition is altered in women with cervical intra-epithelial neoplasia (CIN) compared to healthy controls and is associated with disease progression. However, the impact of CIN excision on the VMB and innate immunity is not known. This observational study aims to explore the impact of CIN excision on the VMB, antimicrobial peptides (AMP) and proinflammatory cytokines. METHODS We sampled 103 non-pregnant, premenopausal women at the time of excisional treatment for CIN and at their 6-month follow-up visit. A further 39 untreated controls with normal cytology were also sampled. We used metataxonomics to group vaginal swab samples into community state types (CSTs) and ELISA to quantify cytokine and AMP levels in matched vaginal secretions. Analyses were performed to compare the bacterial composition and immune analyte levels before and after CIN excision and in healthy controls. RESULTS Women with CIN had significantly higher rates of Lactobacillus species depletion pre-treatment compared to healthy controls (CST IV 21/103, 20% vs 1/39, 3%, p = 0.0081). Excision did not change the VMB composition, with CST IV remaining significantly more prevalent after excision compared to untreated, healthy controls (CST IV 19/103, 20% vs 1/39, 3%, p = 0.0142). Prevotella bivia and Sneathia amnii were significantly higher in samples before treatment compared to untreated controls, and Prevotella bivia remained significantly higher amongst the treated, with less Lactobacillus crispatus compared to untreated controls. IL-1β and IL-8 remained significantly elevated pre- (p < 0.0001 and p = 0.0014, respectively) and post-treatment (p < 0.0001 and p = 0.0035, respectively) compared to untreated controls. Levels of human beta-defensin-1 and secretory leukocyte protease inhibitor were both significantly reduced following CIN excision (p < 0.0001); however, their levels remained lower than controls post-treatment. CONCLUSIONS Women with CIN have an increased prevalence of Lactobacillus sp. depletion, high-diversity VMB composition, and higher levels of proinflammatory cytokines and AMPs compared to normal controls. Surgical excision of the disease reduces levels of vaginal AMPs but does not alter VMB composition or cytokine levels. These findings suggest that women with CIN have an inherent predisposition to a high-diversity proinflammatory environment that is not corrected by disease excision. The failure to re-establish a Lactobacillus-enriched CST may explain why women remain at high risk of pre-invasive and invasive disease recurrence.

Abstract
Purpose To compare the techniques for cone measurement with ultrasound to determine the size of the resected tissue and to evaluate parameters which may be relevant for stratifying women at risk who need surveillance when pregnant. Methods The present study included women with a pathological cervical biopsy. Cervical length and volume were determined by transvaginal ultrasound prior to conization. The pathologist measured the volume of the removed tissue by the fluid displacement technique and using a ruler. A repeat transvaginal ultrasound was performed during a follow-up visit. Factors affecting cone volume as well as the correlation between measurement techniques were analyzed. Results A total of 28 patients underwent cervical excision treatment. The mean cervical volumes measured sonographically before and after the operation were 17.72 ± 7.34 and 13.21 ± 5.43 cm3, respectively. The proportion of volume excised was 25.50 ± 17.43%. A significant correlation was found between the cone depth and the cone volume measured by the fluid displacement technique, and histopathologically and sonographically measured difference in cervical volume. The interobserver reliability coefficient was > 0.9. Analyzing influential parameters, only age affected the extent of cone volume and the correlation between the three measurement techniques. Conclusion Commonly applied techniques of cervical and cone measurement are equivalent and interchangeable. Our ultrasound data show variety in the volume and length of the cervix, and in the proportion of the volume excised at conization. Ultrasound measurements may help the surgeon to estimate not only the dimension of the remaining cervix but also its function.

Abstract
INTRODUCTION There are several local treatment methods for cervical intraepithelial neoplasia that remove or ablate a cone-shaped part of the uterine cervix. There is evidence to suggest that these increase the risk of preterm birth (PTB) and that this is higher for techniques that remove larger parts of the cervix, although the data are conflicting. We present a protocol for a systematic review and network meta-analysis (NMA) that will update the evidence and compare all treatments in terms of fertility and pregnancy complications. METHODS AND ANALYSIS We will search electronic databases (CENTRAL, MEDLINE, EMBASE) from inception till October 2019, in order to identify randomised controlled trials (RCTs) and cohort studies comparing the fertility and pregnancy outcomes among different excisional and ablative treatment techniques and/or to untreated controls. The primary outcome will be PTB (<37 weeks). Secondary outcomes will include severe or extreme PTB, prelabour rupture of membranes, low birth weight (<2500 g), neonatal intensive care unit admission, perinatal mortality, total pregnancy rates, first and second trimester miscarriage. We will search for published and unpublished studies in electronic databases, trial registries and we will hand-search references of published papers. We will assess the risk of bias in RCTs and cohort studies using tools developed by the Cochrane collaboration. Two investigators will independently assess the eligibility, abstract the data and assess the risk of bias of the identified studies. For each outcome, we will perform a meta-analysis for each treatment comparison and an NMA once the transitivity assumption holds, using the OR for dichotomous data. We will use CINeMA (Confidence in Network meta-analysis) to assess the quality of the evidence for the primary outcome. ETHICS AND DISSEMINATION Ethical approval is not required. Results will be disseminated to academic beneficiaries, medical practitioners, patients and the public. PROSPERO REGISTRATION NUMBER CRD42018115495.

Abstract
INTRODUCTION Local treatments for cervical intraepithelial neoplasia (CIN) and microinvasive disease remove or ablate a cone-shaped part of the uterine cervix containing the abnormal cells. A trend toward less radical techniques has raised concerns that this may adversely impact the rates of precancerous and cancerous recurrence. However, there has been no strong evidence to support such claims. We hereby describe a protocol of a systematic review and network meta-analysis that will update the evidence and compare all relevant treatments in terms of efficacy and complications. METHODS AND ANALYSIS Literature searches in electronic databases (CENTRAL, MEDLINE, EMBASE) or trial registries will identify published and unpublished randomised controlled trials (RCTs) and cohort studies comparing the efficacy and complications among different excisional and ablative techniques. The excisional techniques include cold knife, laser or Fischer cone, large loop or needle excision of the transformation zone and the ablative radical point diathermy, cryotherapy, cold coagulation or laser ablation. The primary outcome will be residual/recurrent disease defined as abnormal histology or cytology of any grade, while secondary outcomes will include treatment failure rates defined as high-grade histology or cytology, histologically confirmed CIN1+ or histologically confirmed CIN2+, human papillomavirus positivity rates, involved margins rates, bleeding and cervical stenosis rates. We will assess the risk of bias in RCTs and observational studies using tools developed by the Cochrane Collaboration. Two authors will independently assess study eligibility, abstract the data and assess the risk of bias. Random-effects meta-analyses and network meta-analyses will be conducted using the OR for dichotomous outcomes and the mean difference for continuous outcomes. The quality of the evidence for the primary outcome will be assessed using the CINeMA (Confidence In Network Meta-Analysis) tool. ETHICS AND DISSEMINATION Ethical approval is not required. We will disseminate findings to clinicians, policy-makers, patients and the public. PROSPERO REGISTRATION NUMBER CRD42018115508.

Obstetric outcomes in patients who have undergone excisional treatment for high-grade cervical squamous intra-epithelial neoplasia. Eur J Obstet Gynecol Reprod Biol 2019; 236:210-213. [PMID: 30922526 DOI: 10.1016/j.ejogrb.2019.02.025] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2019] [Accepted: 02/20/2019] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To evaluate the relationships between excisional treatment for high-grade cervical intra-epithelial neoplasia (CIN2+) and obstetric outcomes in terms of preterm delivery risk, premature rupture of membrane (PROM) and type of delivery, and between pre-term delivery and the type of excisional technique (radio frequency excision, laser conization). METHODS This was a retrospective study of the obstetric outcomes of 2316 women aged 25-45 years who underwent excisional treatment for CIN2+ at the Obstetric and Gynecological Clinic of Ospedale Maggiore della Carità in Novara and at the Obstetric and Gynecological Department of Ospedale Sant'Anna in Torino in the period 2005-2014 and were evaluated until April 2016, and 57,937 untreated women of the same age, from the same centers. RESULTS After treatment, 320 women had at least one pregnancy leading to delivery after a mean of 3.35 years. Treatment significantly increased the risk of preterm delivery. Compared with no treatment, the risk of preterm birth was higher in women who had undergone treatment (33.13% vs. 6.60%). Techniques removing or ablating more tissue, such as large loop excision of the transformation zone, were associated with worse outcomes (OR 2.96, 95% IC 1.72-5.10). Smoking habits significantly increase the risk of preterm delivery in the treated women (OR 2.82, 95% IC 1.61-4.9). The risk of premature rupture of the membranes (PROM) (40% vs. 23.22%), the risk of preterm PROM (pPROM) (13.13% vs. 2.71%) and dystocic births (18.75% vs 4.48%) were also significantly increased after treatment. Caesarean sections were less frequent among the treated women (15.94% vs. 32.41%). CONCLUSIONS Our findings reveal a relationship between cervical excisional treatment and pre-term delivery, PROM, and the method of delivery. In order to minimise risk and guarantee the best obstetric outcome, patient treatment and follow-up should be personalised.

Abstract
OBJECTIVES To evaluate cervical regeneration at 6 months following excisional treatment for high-grade cervical intraepithelial neoplasia (CIN), and to investigate the effect of cone dimensions, age of patients and technique of excision on the efficacy of the regeneration process. DESIGN Prospective observational multicentric study. SETTING Three tertiary care and research centres. PARTICIPANTS Among the 197 eligible women of childbearing age, older than 25 years of age, undergoing for the first time a loop electrosurgical excision procedure or carbon dioxide laser cervical excision for a high-grade CIN at the colposcopy-directed cervical punch biopsy, and with a final diagnosis of high-grade CIN, 165 completed the 6-month follow-up and were included in the analysis. PRIMARY OUTCOME MEASURES The cervical length and volume regeneration (%) after 6 months from procedure were determined by three-dimensional ultrasound, and the correlation of regeneration with cone dimensions, age and excision technique was evaluated. RESULTS The mean±SD cervical length regeneration at 6 months was 89.5%±6.3% and the mean±SD cervical volume regeneration was 86.3%±13.2%. At the multivariate analysis, a significant and independent inverse correlation between excised cone length and cervical regeneration emerged (r=-0.39, P<0.001). A significantly negative trend in length regeneration at 6 months from procedure with an increasing class of cone length was found (P<0.001). No significant association was found in relation with patient age at the time of procedure or with the technique of excision. CONCLUSIONS Cervical length regeneration at 6 months from excisional treatments is negatively affected by an increasing cone length but not from the age of the patient or the technique of excision. While still achieving equal clinical efficacy, it is crucial to contain cone dimensions, in order to favour a greater length regeneration, reducing the cervical harm and the potential future obstetric complications.

Abstract
PURPOSE To compare the pregnancy outcomes between women who were treated with cold-coagulation versus large loop excision of the transformation zone (LLETZ) for cervical intraepithelial neoplasia. METHODS This was a retrospective cohort study of women who had a single cervical treatment between 2010 and 2011. We identified those women who had a singleton pregnancy subsequent to their cervical treatment until September 2017. Women with previous cervical treatment, previous miscarriage or preterm delivery were excluded. RESULTS We identified 86 women with a pregnancy after LLETZ treatment and 75 women after cold coagulation. Those who had LLETZ when compared to cold coagulation miscarried more often in the first trimester (33.7 vs 17.3%; p = 0.01) than in the second trimester. In women with LLETZ this effect of increased early miscarriage was shown to be prolonged and to persist up to 17 months after excision. Women with LLETZ when compared to cold coagulation had higher spontaneous preterm birth rates (8.9 vs 6.7%) even though the difference was non significant, with the earliest spontaneous preterm birth occurring at 32 weeks and 34 weeks, respectively. CONCLUSION We found that women who received LLETZ treatment when compared to cold coagulation had higher spontaneous preterm birth rates in their subsequent pregnancy and miscarried more frequently in the first trimester, and demonstrated an increased early miscarriage risk that persisted for more than a year after excisional treatment.

Abstract
BACKGROUND The mean age of women undergoing local treatment for pre-invasive cervical disease (cervical intra-epithelial neoplasia; CIN) or early cervical cancer (stage IA1) is around their 30s and similar to the age of women having their first child. Local cervical treatment has been correlated to adverse reproductive morbidity in a subsequent pregnancy, however, published studies and meta-analyses have reached contradictory conclusions. OBJECTIVES To assess the effect of local cervical treatment for CIN and early cervical cancer on obstetric outcomes (after 24 weeks of gestation) and to correlate these to the cone depth and comparison group used. SEARCH METHODS We searched the following databases: Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library, 2017, Issue 5), MEDLINE (up to June week 4, 2017) and Embase (up to week 26, 2017). In an attempt to identify articles missed by the search or unpublished data, we contacted experts in the field and we handsearched the references of the retrieved articles and conference proceedings. SELECTION CRITERIA We included all studies reporting on obstetric outcomes (more than 24 weeks of gestation) in women with or without a previous local cervical treatment for any grade of CIN or early cervical cancer (stage IA1). Treatment included both excisional and ablative methods. We excluded studies that had no untreated reference population, reported outcomes in women who had undergone treatment during pregnancy or had a high-risk treated or comparison group, or both DATA COLLECTION AND ANALYSIS: We classified studies according to the type of treatment and the obstetric endpoint. Studies were classified according to method and obstetric endpoint. Pooled risk ratios (RR) and 95% confidence intervals (CIs) were calculated using a random-effects model and inverse variance. Inter-study heterogeneity was assessed with I2 statistics. We assessed maternal outcomes that included preterm birth (PTB) (spontaneous and threatened), preterm premature rupture of the membranes (pPROM), chorioamnionitis, mode of delivery, length of labour, induction of delivery, oxytocin use, haemorrhage, analgesia, cervical cerclage and cervical stenosis. The neonatal outcomes included low birth weight (LBW), neonatal intensive care unit (NICU) admission, stillbirth, perinatal mortality and Apgar scores. MAIN RESULTS We included 69 studies (6,357,823 pregnancies: 65,098 pregnancies of treated and 6,292,725 pregnancies of untreated women). Many of the studies included only small numbers of women, were of heterogenous design and in their majority retrospective and therefore at high risk of bias. Many outcomes were assessed to be of low or very low quality (GRADE assessment) and therefore results should be interpreted with caution. Women who had treatment were at increased overall risk of preterm birth (PTB) (less than 37 weeks) (10.7% versus 5.4%, RR 1.75, 95% CI 1.57 to 1.96, 59 studies, 5,242,917 participants, very low quality), severe (less than 32 to 34 weeks) (3.5% versus 1.4%, RR 2.25, 95% CI 1.79 to 2.82), 24 studies, 3,793,874 participants, very low quality), and extreme prematurity (less than 28 to 30 weeks) (1.0% versus 0.3%, (RR 2.23, 95% CI 1.55 to 3.22, 8 studies, 3,910,629 participants, very low quality), as compared to women who had no treatment.The risk of overall prematurity was higher for excisional (excision versus no treatment: 11.2% versus 5.5%, RR 1.87, 95% CI 1.64 to 2.12, 53 studies, 4,599,416 participants) than ablative (ablation versus no treatment: 7.7% versus 4.6%, RR 1.35, 95% CI 1.20 to 1.52, 14 studies, 602,370 participants) treatments and the effect was higher for more radical excisional techniques (less than 37 weeks: cold knife conisation (CKC) (RR 2.70, 95% CI 2.14 to 3.40, 12 studies, 39,102 participants), laser conisation (LC) (RR 2.11, 95% CI 1.26 to 3.54, 9 studies, 1509 participants), large loop excision of the transformation zone (LLETZ) (RR 1.58, 95% CI 1.37 to 1.81, 25 studies, 1,445,104 participants). Repeat treatment multiplied the risk of overall prematurity (repeat versus no treatment: 13.2% versus 4.1%, RR 3.78, 95% CI 2.65 to 5.39, 11 studies, 1,317,284 participants, very low quality). The risk of overall prematurity increased with increasing cone depth (less than 10 mm to 12 mm versus no treatment: 7.1% versus 3.4%, RR 1.54, 95% CI 1.09 to 2.18, 8 studies, 550,929 participants, very low quality; more than 10 mm to 12 mm versus no treatment: 9.8% versus 3.4%, RR 1.93, 95% CI 1.62 to 2.31, 8 studies, 552,711 participants, low quality; more than 15 mm to 17 mm versus no treatment: 10.1 versus 3.4%, RR 2.77, 95% CI 1.95 to 3.93, 4 studies, 544,986 participants, very low quality; 20 mm or more versus no treatment: 10.2% versus 3.4%, RR 4.91, 95% CI 2.06 to 11.68, 3 studies, 543,750 participants, very low quality). The comparison group affected the magnitude of effect that was higher for external, followed by internal comparators and ultimately women with disease, but no treatment. Untreated women with disease and the pre-treatment pregnancies of the women who were treated subsequently had higher risk of overall prematurity than the general population (5.9% versus 5.6%, RR 1.24, 95% CI 1.14 to 1.34, 15 studies, 4,357,998 participants, very low quality).pPROM (6.1% versus 3.4%, RR 2.36, 95% CI 1.76 to 3.17, 21 studies, 477,011 participants, very low quality), low birth weight (7.9% versus 3.7%, RR 1.81, 95% CI 1.58 to 2.07, 30 studies, 1,348,206 participants, very low quality), NICU admission rate (12.6% versus 8.9%, RR 1.45, 95% CI 1.16 to 1.81, 8 studies, 2557 participants, low quality) and perinatal mortality (0.9% versus 0.7%, RR 1.51, 95% CI 1.13 to 2.03, 23 studies, 1,659,433 participants, low quality) were also increased after treatment. AUTHORS' CONCLUSIONS Women with CIN have a higher baseline risk for prematurity. Excisional and ablative treatment appears to further increases that risk. The frequency and severity of adverse sequelae increases with increasing cone depth and is higher for excision than it is for ablation. However, the results should be interpreted with caution as they were based on low or very low quality (GRADE assessment) observational studies, most of which were retrospective.

Abstract
OBJECTIVE To evaluate whether the dimensions of the cones removed during large loop excision of the transformation zone have decreased over time. Secondly, whether these changes were associated with a lower risk of obstetrical harms on a subsequent pregnancy. STUDY DESIGN A retrospective matched cohort study was performed in a tertiary referral unit in Belgium. A total of 97 women were identified from a database of women who underwent excisional treatment for cervical precancer between January 1st, 2004 and December 31st, 2012, and delivered before December 31st, 2014. The control group consisted of 120 non-treated women who had no history of cervical intra-epithelial neoplasia. Data on smoking status; gestational age at delivery; number of conisations; time interval between treatment and pregnancy; dimensions of the cone; severity of the lesion; and the extra resection of endocervical tissue were collected. These data were compared with those from a previous similar study at the University Hospital of Leuven in 2009, which database we enriched with information on the cone dimensions. Main outcome variables were gestational age at delivery, birthweight and neonatal condition at birth. RESULTS Only a significant lower birthweight could be found in the treated group compared to the control group (3364g [95% CI 3094-3290] versus 3364g [95% CI 3253-3475], P=0.023). The current study showed no increase in preterm birth rate after conisation and no relationship between volume or depth of the cone and preterm birth could be found. Over the period 1999-2014, a significant decrease in all dimensions was observed: on average -0.3mm, -0.3mm, -0.4mm and -132mm3 per year, for the depth, anteroposterior and transverse diameter and the volume, respectively. CONCLUSIONS Our two successive studies showed a significant trend towards smaller cones which was accompanied by a decrease in preterm birth after excisional treatment. The clinician could limit the size of the cone to avoid obstetrical harms, but needs to be aware of the oncological safety as well.

Abstract
Background Methylation of the human papillomavirus (HPV) DNA has been proposed as a novel biomarker. Here, we correlated the mean methylation level of 12 CpG sites within the L1 gene, to the histological grade of cervical precancer and cancer. We assessed whether HPV L1 gene methylation can predict the presence of high-grade disease at histology in women testing positive for HPV16 genotype. Methods Pyrosequencing was used for DNA methylation quantification and 145 women were recruited. Results We found that the L1 HPV16 mean methylation (±SD) significantly increased with disease severity (cervical intraepithelial neoplasia [CIN] 3, 17.9% [±7.2] vs CIN2, 11.6% [±6.5], P < .001 or vs CIN1, 9.0% [±3.5], P < .001). Mean methylation was a good predictor of CIN3+ cases; the area under the curve was higher for sites 5611 in the prediction of CIN2+ and higher for position 7145 for CIN3+. The evaluation of different methylation thresholds for the prediction of CIN3+ showed that the optimal balance of sensitivity and specificity (75.7% and 77.5%, respectively) and positive and negative predictive values (74.7% and 78.5%, respectively) was achieved for a methylation of 14.0% with overall accuracy of 76.7%. Conclusions Elevated methylation level is associated with increased disease severity and has good ability to discriminate HPV16-positive women that have high-grade disease or worse.

Abstract
BACKGROUND A significant number of women are diagnosed with minor cytological abnormalities on cervical screening. Many authorities recommend surveillance as spontaneous regression might occur. However, attendance for cytological follow-up decreases with time and might put some women at risk of developing invasive disease. OBJECTIVES To assess the optimum management strategy for women with minor cervical cytological abnormalities (atypical squamous cells of undetermined significance - ASCUS or low-grade squamous intra-epithelial lesions - LSIL) at primary screening in the absence of HPV (human papillomavirus) DNA test. SEARCH METHODS We searched the following electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL Issue 4, 2016), MEDLINE (1946 to April week 2 2016) and Embase (1980 to 2016 week 16). SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing immediate colposcopy to cytological surveillance in women with atypical squamous cells of undetermined significance (ASCUS/borderline) or low-grade squamous intra-epithelial lesions (LSIL/mild dyskaryosis). DATA COLLECTION AND ANALYSIS The primary outcome measure studied was the occurrence of cervical intra-epithelial neoplasia (CIN). The secondary outcome measures studied included default rate, clinically significant anxiety and depression, and other self-reported adverse effects.We classified studies according to period of surveillance, at 6, 12, 24 or 36 months, as well as at 18 months, excluding a possible exit-examination. We calculated pooled risk ratios (RR) and 95% confidence intervals (CI) using a random-effects model with inverse variance weighting. Inter-study heterogeneity was assessed with I2 statistics. MAIN RESULTS We identified five RCTs with 11,466 participants that fulfilled the inclusion criteria. There were 18 cases of invasive cervical cancer, seven in the immediate colposcopy and 11 in the cytological surveillance groups, respectively. Although immediate colposcopy detects CIN2+ and CIN3+ earlier than cytology, the differences were no longer observed at 24 months (CIN2+: 3 studies, 4331 women; 17.9% versus 18.3%, RR 1.14, CI 0.66 to 1.97; CIN3+: 3 studies, 4331 women; 10.3% versus 11.9%, RR 1.02, CI 0.53 to 1.97). The inter-study heterogeneity was considerable (I2 greater than 90%). Furthermore, the inclusion of the results of the exit examinations at 24 months, which could inflate the CIN detection rate of cytological surveillance, may have led to study design-derived bias; we therefore considered the evidence to be of low quality.When we excluded the exit examination, the detection rate of high-grade lesions at the 18-month follow-up was higher after immediate colposcopy (CIN2+: 2 studies, 4028 women; 14.3% versus 10.1%, RR 1.50, CI 1.12 to 2.01; CIN3+: 2 studies, 4028 women, 7.8% versus 6.9%, RR 1.24, CI 0.77 to 1.98) both had substantial inter-study heterogeneity (I2 greater than 60%) and we considered the evidence to be of moderate quality).The meta-analysis revealed that immediate referral to colposcopy significantly increased the detection of clinically insignificant cervical abnormalities, as opposed to repeat cytology after 24 months of surveillance (occurrence of koilocytosis: 2 studies, 656 women; 32% versus 21%, RR 1.49, 95% CI 1.17 to 1.90; moderate-quality evidence) incidence of any CIN: 2 studies, 656 women; 64% versus 32%, RR 2.02, 95% CI 1.33 to 3.08, low-quality evidence; incidence of CIN1: 2 studies, 656 women; 21% versus 8%, RR 2.58, 95% CI 1.69 to 3.94, moderate-quality evidence).Due to differences in trial designs and settings, there was large variation in default rates between the included studies. The risk for default was higher for the repeat cytology group, with a four-fold increase at 6 months, a six-fold at 12 and a 19-fold at 24 months (6 months: 3 studies, 5117 women; 6.3% versus 13.3%, RR 3.85, 95% CI 1.27 to 11.63, moderate-quality evidence; 12 months: 3 studies, 5115 women; 6.3% versus 14.8%, RR 6.39, 95% CI 1.49 to 29.29, moderate-quality evidence; 24 months: 3 studies, 4331 women; 0.9% versus 16.1%, RR 19.1, 95% CI 9.02 to 40.43, moderate-quality evidence). AUTHORS' CONCLUSIONS Based on low- or moderate-quality evidence using the GRADE approach and generally low risk of bias, the detection rate of CIN2+ or CIN3+ after two years does not appear to differ between immediate colposcopy and cytological surveillance in the absence of HPV testing, although women may default from follow-up. Immediate colposcopy probably leads to earlier detection of high-grade lesions, but also detects more clinically insignificant low-grade lesions. Colposcopy may therefore be the first choice when good compliance is not assured. These results emphasize the need for an accurate reflex HPV triage test to distinguish women who need diagnostic follow-up from those who can return safely to routine recall.

Abstract
OBJECTIVE To assess the effect of treatment for cervical intraepithelial neoplasia (CIN) on obstetric outcomes and to correlate this with cone depth and comparison group used. DESIGN Systematic review and meta-analysis. DATA SOURCES CENTRAL, Medline, Embase from 1948 to April 2016 were searched for studies assessing obstetric outcomes in women with or without previous local cervical treatment. DATA EXTRACTION AND SYNTHESIS Independent reviewers extracted the data and performed quality assessment using the Newcastle-Ottawa criteria. Studies were classified according to method and obstetric endpoint. Pooled risk ratios were calculated with a random effect model and inverse variance. Heterogeneity between studies was assessed with I(2) statistics. MAIN OUTCOME MEASURES Obstetric outcomes comprised preterm birth (including spontaneous and threatened), premature rupture of the membranes, chorioamnionitis, mode of delivery, length of labour, induction of delivery, oxytocin use, haemorrhage, analgesia, cervical cerclage, and cervical stenosis. Neonatal outcomes comprised low birth weight, admission to neonatal intensive care, stillbirth, APGAR scores, and perinatal mortality. RESULTS 71 studies were included (6 338 982 participants: 65 082 treated/6 292 563 untreated). Treatment significantly increased the risk of overall (<37 weeks; 10.7% v 5.4%; relative risk 1.78, 95% confidence interval 1.60 to 1.98), severe (<32-34 weeks; 3.5% v 1.4%; 2.40, 1.92 to 2.99), and extreme (<28-30 weeks; 1.0% v 0.3%; 2.54, 1.77 to 3.63) preterm birth. Techniques removing or ablating more tissue were associated with worse outcomes. Relative risks for delivery at <37 weeks were 2.70 (2.14 to 3.40) for cold knife conisation, 2.11 (1.26 to 3.54) for laser conisation, 2.02 (1.60 to 2.55) for excision not otherwise specified, 1.56 (1.36 to 1.79) for large loop excision of the transformation zone, and 1.46 (1.27 to 1.66) for ablation not otherwise specified. Compared with no treatment, the risk of preterm birth was higher in women who had undergone more than one treatment (13.2% v 4.1%; 3.78, 2.65 to 5.39) and with increasing cone depth (≤10-12 mm; 7.1% v 3.4%; 1.54, 1.09 to 2.18; ≥10-12 mm: 9.8% v 3.4%, 1.93, 1.62 to 2.31; ≥15-17 mm: 10.1% v 3.4%; 2.77, 1.95 to 3.93; ≥20 mm: 10.2% v 3.4%; 4.91, 2.06 to 11.68). The choice of comparison group affected the magnitude of effect. This was higher for external comparators, followed by internal comparators, and ultimately women with disease who did not undergo treatment. In women with untreated CIN and in pregnancies before treatment, the risk of preterm birth was higher than the risk in the general population (5.9% v 5.6%; 1.24, 1.14 to 1.35). Spontaneous preterm birth, premature rupture of the membranes, chorioamnionitis, low birth weight, admission to neonatal intensive care, and perinatal mortality were also significantly increased after treatment. : CONCLUSIONS Women with CIN have a higher baseline risk for prematurity. Excisional and ablative treatment further increases that risk. The frequency and severity of adverse sequelae increases with increasing cone depth and is higher for excision than for ablation.

Abstract
The objective of our study was to determine whether removing multiple pieces of cervical tissue during large loop excision of the transformation zone (LLETZ) reduced the margin positivity of excision and cytology recurrence rates at follow-up. We conducted an observational cohort study and identified 462 women having had a single LLETZ treatment for cervical intraepithelial neoplasia (CIN) over a two-year period. Women with previous cervical treatment, cervical cancer on the excised tissue or missing follow-up data were excluded. Multiple regression analysis showed that removal of cervical tissue in multiple pieces did not offer any benefit in removing more disease and less recurrence rates. When multiple pieces were taken there was a four-fold increased risk for inconclusive excision margins as reported by the histopathologist. Removal of multiple pieces led to significantly more tissue being removed which may expose the patient to an increased risk of preterm delivery in a future pregnancy.

Abstract
INTRODUCTION High-risk HPV (HR-HPV) related invasive cervical cancer (ICC) causes >270,000 deaths per annum world-wide with over 85% of these occurring in low-resource countries. Ablative and excisional treatment modalities are restricted for use with high-grade pre-cancerous cervical disease with HPV infection and low-grade dysplasia mostly managed by a watch-and-wait policy. AREAS COVERED Various pharmacological approaches have been investigated as non-destructive alternatives for the treatment of HR-HPV infection and associated dysplasia. These are discussed dealing with efficacy, ease-of-use (physician or self-applied), systemic or locally applied, side-effects, cost and risks. The main focus is the perceived impact on current clinical practice of a self-applied, effective and safe pharmacological anti-HPV treatment. EXPERT OPINION Current prophylactic HPV vaccines are expensive, HPV type restricted and have little effect in already infected women. Therapeutic vaccines are under development but are also HPV type-restricted. At present, the developed nations use national cytology screening and surgical procedures to treat only women identified with HPV-related high-grade dysplastic disease. However, since HPV testing is rapidly replacing cytology as the test-of-choice, a suitable topically-applied and low-cost antiviral treatment could be an ideal solution for treatment of HPV infection per se with test-of-cure carried out by repeat HPV testing. Cytology would only then be necessary for women who remained HPV positive. Although of significant benefit in the developed countries, combining such a treatment with self-sampled HPV testing could revolutionise the management of this disease in the developing world which lack both the infrastructure and resources to establish national cytology screening programs.

Abstract
BACKGROUND Cervical intra-epithelial neoplasia (CIN) typically occurs in young women of reproductive age. Although several studies have reported the impact that cervical conservative treatment may have on obstetric outcomes, there is much less evidence for fertility and early pregnancy outcomes. OBJECTIVES To assess the effect of cervical treatment for CIN (excisional or ablative) on fertility and early pregnancy outcomes. SEARCH METHODS We searched in January 2015 the following databases: the Cochrane Gynaecological Cancer Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library, Issue 12, 2014), MEDLINE (up to November week 3, 2014) and EMBASE (up to week 52, 2014). SELECTION CRITERIA We included all studies reporting on fertility and early pregnancy outcomes (less than 24 weeks of gestation) in women with a history of CIN treatment (excisional or ablative) as compared to women that had not received treatment. DATA COLLECTION AND ANALYSIS Studies were classified according to the treatment method used and the fertility or early pregnancy endpoint. Pooled risk ratios (RR) and 95% confidence intervals (CI) were calculated using a random-effects model and inter-study heterogeneity was assessed with I(2). Two review authors (MK, AM) independently assessed the eligibility of retrieved papers and risk of bias. The two review authors then compared their results and any disagreements were resolved by discussion. If still unresolved, a third review author (MA) was involved until consensus was reached. MAIN RESULTS Fifteen studies (2,223,592 participants - 25,008 treated and 2,198,584 untreated) that fulfilled the inclusion criteria for this review were identified from the literature search. The meta-analysis demonstrated that treatment for CIN did not adversely affect the chances of conception. The overall pregnancy rate was higher for treated (43%) versus untreated women (38%; RR 1.29, 95% CI 1.02 to 1.64; 4 studies, 38,050 participants, very low quality), although the inter-study heterogeneity was considerable (P < 0.01). The pregnancy rates in treated and untreated women with an intention to conceive (88% versus 95%, RR 0.93, 95% CI 0.80 to 1.08; 2 studies, 70 participants, very low quality) and the number of women requiring more than 12 months to conceive (14% versus 9%, RR 1.45, 95% CI 0.89 to 2.37; 3 studies, 1348 participants, very low quality) were no different. Although the total miscarriage rate (4.6% versus 2.8%, RR 1.04, 95% CI 0.90 to 1.21; 10 studies, 39,504 participants, low quality) and first trimester miscarriage rate (9.8% versus 8.4%, RR 1.16, 95% CI 0.80 to 1.69, 4 studies, 1103 participants, low quality) was similar for treated and untreated women, CIN treatment was associated with an increased risk of second trimester miscarriage, (1.6% versus 0.4%, RR 2.60, 95% CI 1.45 to 4.67; 8 studies, 2,182,268 participants, low quality). The number of ectopic pregnancies (1.6% versus 0.8%, RR 1.89, 95% CI 1.50 to 2.39; 6 studies, 38,193 participants, low quality) and terminations (12.2% versus 7.4%, RR 1.71, 95% CI 1.31 to 2.22; 7 studies, 38,208 participants, low quality) were also higher in treated women.The results should be interpreted with caution. The included studies were often small with heterogenous design. Most of these studies were retrospective and of low or very low quality (GRADE assessment) and were therefore prone to bias. Subgroup analyses for the individual treatment methods and comparison groups and analysis to stratify for the cone length was not possible. AUTHORS' CONCLUSIONS This meta-analysis suggests that treatment for CIN does not adversely affect fertility, although treatment was associated with an increased risk of miscarriage in the second trimester. These results should be interpreted with caution as the included studies were non-randomised and many were of low or very low quality and therefore at high risk of bias. Research should explore mechanisms that may explain the increase in mid-trimester miscarriage risk and stratify this impact of treatment by the length of the cone and the treatment method used.

Abstract
OBJECTIVE To determine the impact of cervical excision for cervical intraepithelial neoplasia on fertility and early pregnancy outcomes. DESIGN Systematic review and meta-analysis of cohort studies. DATA SOURCES Medline and Embase. ELIGIBILITY CRITERIA Studies assessing fertility and early pregnancy outcomes in women with a history of treatment for cervical intraepithelial neoplasia versus untreated women. We classified the included studies according to treatment type and fertility or early pregnancy endpoint. ANALYSIS Pooled relative risks and 95% confidence intervals using a random effect model, and interstudy heterogeneity with I(2) statistics. RESULTS 15 studies fulfilled the inclusion criteria and were included. The meta-analysis did not provide any evidence that treatment for cervical intraepithelial neoplasia adversely affected the chances of conception. The overall pregnancy rate was higher for treated women than for untreated women (four studies; 43% v 38%, pooled relative risk 1.29, 95% confidence interval 1.02 to 1.64), although the heterogeneity between studies was high (P<0.0001). Pregnancy rates did not differ between women with an intention to conceive (two studies; 88% v 95%, 0.93, 0.80 to 1.08) and the number requiring more than 12 months to conceive (three studies, 15% v 9%, 1.45, 0.89 to 2.37). Although the rates for total miscarriages (10 studies; 4.6% v 2.8%, 1.04, 0.90 to 1.21) and miscarriage in the first trimester (four studies; 9.8% v 8.4%, 1.16, 0.80 to 1.69) was similar for treated and untreated women, cervical treatment was associated with a significantly increased risk of miscarriage in the second trimester. The rate was higher for treated women than for untreated women (eight studies; 1.6% v 0.4%, 16,558 women; 2.60, 1.45 to 4.67). The number of ectopic pregnancies (1.6% v 0.8%; 1.89, 1.50 to 2.39) and terminations (12.2% v 7.4%; 1.71, 1.31 to 2.22) was also higher for treated women. CONCLUSION There is no evidence suggesting that treatment for cervical intraepithelial neoplasia adversely affects fertility, although treatment was associated with a significantly increased risk of miscarriages in the second trimester. Research should explore mechanisms that may explain this increase in risk and stratify the impact that treatment may have on fertility and early pregnancy outcomes by the size of excision and treatment method used.

Proportion of cervical excision for cervical intraepithelial neoplasia as a predictor of pregnancy outcomes. Int J Gynaecol Obstet 2014; 128:141-7. [PMID: 25444615 DOI: 10.1016/j.ijgo.2014.07.038] [Citation(s) in RCA: 47] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2014] [Revised: 07/25/2014] [Accepted: 09/24/2014] [Indexed: 11/21/2022]
Abstract
OBJECTIVE To assess how the proportion of the cervical volume/length removed during treatment for cervical intraepithelial neoplasia (CIN) varies and whether this correlates to the pregnancy duration at delivery. METHODS The present prospective observational study included 142 women undergoing CIN treatment at a university hospital during 2009-2013. The pretreatment and post-treatment cervical dimensions and cone size were measured with magnetic resonance imaging, three-dimensional transvaginal ultrasonography, or two-dimensional transvaginal ultrasonography, and the correlation between pregnancy outcomes and the relative proportion of the cervix excised was assessed. RESULTS Pretreatment cervical volumes and cone volumes varied substantially (range 11-40 cm(3) and 0.6-8 cm(3), respectively). The proportion of the volume excised ranged from 2.2% to 39.4%. Sixteen (11%) women conceived following treatment; 12 had a live birth (seven at term, three preterm). The pregnancy duration at delivery was significantly correlated with the proportion of the cervical volume (r=-0.9; P<0.001) and length (r=-0.7; P=0.01) excised and the cone volume (r=-0.6; P=0.04). CONCLUSION The pretreatment cervical dimensions and the proportions of the volume/length excised vary substantially, and the latter correlates with the pregnancy duration. Assessment of the proportion excised might help to stratify women at risk who need intensive surveillance when pregnant.

Abstract
OBJECTIVES New human papillomavirus (HPV)-related biomarkers may allow better identification of clinically significant lesions that warrant excision and, conversely, identification of the false positive cases that have been overreported by traditional techniques. The aim of this study was to investigate how the expression of several HPV-related biomarkers correlates to the severity of the lesion at treatment. DESIGN Prospective observational study. SETTING University Hospital (2009-2011). POPULATION All women submitted for excisional treatment. METHODS A liquid-based cytology sample was obtained before treatment and was tested for HPV typing, mRNA E6 & E7 with NASBA or flow cytometry and p16. All women had histological diagnosis in the form of excisional cone (gold standard). MAIN OUTCOME MEASURES Correlation of HPV biomarker positivity rates to the grade of the lesion at treatment histology. RESULTS Two hundred women were recruited: 23 were found to have negative histology (11.5%), 79 (39.5%) CIN1, 50 (25.0%) CIN2 and 48 (24.0%) CIN3. All biomarkers (HPV DNA typing, HR HPV, single HPV 16/18, mRNA E6 & E7 expression and p16) revealed an increased linear positivity rate with increasing severity and grade of the lesion (chi-squared test for trend p < 0.05). This was stronger for HPV (all and high-risk) followed by mRNA with NASBA, flow cytometry, HPV 16/18 and ultimately p16 immunostaining. CONCLUSIONS The linear correlation between various HPV-related biomarkers and the grade of the lesion suggests that these biomarkers may prove to be useful in the prediction of CIN grade and, as a result, the need for treatment.

Abstract
OBJECTIVE Previous studies have shown mixed results for pregnancy outcomes after loop electrosurgical excision procedure (LEEP); however, evidence is lacking regarding the pregnancy outcome of spontaneous abortion with respect to time elapsed from LEEP to pregnancy. We investigated risks of spontaneous abortion and preterm birth as they relate to time elapsed from LEEP to pregnancy. METHODS A 10-year, multicenter cohort study of women who underwent LEEP was performed between 1996 and 2006. Trained research nurses conducted telephone interviews with all patients to complete data extraction unavailable in charts. Median time from LEEP to pregnancy for spontaneous abortion compared with no spontaneous abortion and preterm birth before 34 and before 37 weeks of gestation compared with term birth were estimated. Patients with time intervals less than 12 months compared with 12 months or more from LEEP to pregnancy were then compared with identify adjusted odds ratios for spontaneous abortion and preterm birth. RESULTS Five hundred ninety-six patients met inclusion criteria. Median time from LEEP to pregnancy was significantly shorter for women with a spontaneous abortion (20 months [interquartile range 11.2-40.9] compared with 31 months [interquartile range 18.7-51.2]; P=.01) but did not differ for women with a term birth compared with preterm birth. Women with a time interval less than 12 months compared with 12 months or more were at significantly increased risk for spontaneous abortion (17.9% compared with 4.6%; adjusted odds ratio 5.6; 95% confidence interval 2.5-12.7). No increased risk was identified for preterm birth before 34 weeks of gestation or before 37 weeks of gestation. CONCLUSION Women with a shorter time interval from LEEP to pregnancy are at increased risk for spontaneous abortion but not preterm birth. LEVEL OF EVIDENCE : II.

Abstract
The obstetrical consequences of conisation for cervical intraepithelial neoplasia (CIN) should be considered since patients affected by these lesions are actually younger and most often desire further pregnancies. The loop electrosurgical excision procedure (LEEP), which is currently mostly used, achieves cure rate varying according to the authors between 80 and 95%. However, the most recent data show an increase of obstetrical morbidity, especially prematurity, after LEEP excision. As the frequency and severity of prematurity is correlated to the size and depth of the LEEP, we should minimize as much as possible the resection for these young patients.

Abstract
OBJECTIVES To assess whether there is a correlation between the length of a conization specimen and the length of the cervix measured by vaginal ultrasonography after the operation PATIENTS AND METHODS Prospective observational study including patients less than 45 years with measurement of cervical length before and the day of the conization, and measuring the histological length of the specimen. RESULTS Among the 40 patients enrolled, the average ultrasound measurements before conization was 26.9 mm (± 4.9 mm) against 18.1mm (± 4.4mm) after conization with a mean difference of 8.8mm (± 2.4mm) (difference statistically significant P<.0001). The extent of histological specimen was 9 mm (± 2.2mm) on average. A correlation between ultrasound and histological measurements with a correlation coefficient R=0.85 was found statistically significant (P<0.0001). Moreover, the rate of cervix length remove by loop-excision in our series is 33% (± 8.5%). DISCUSSION A good correlation between the measurements of the specimen and the cervical ultrasound length before and after conization was found, as a significant reduction in cervical length after conization. The precise length of the specimen should be known in case of pregnancy and the prevention of prematurity due to conization rests on selected indications and efficient surgical technique.

Abstract
AIMS To determine appropriate cone dimensions for predicting margin status after large loop excision of transformation zone (LLETZ) treatment. METHODS An observational study performed at the Colposcopy Unit of a university hospital setting involving patients who underwent LLETZ conisation within a 1-year period. Data concerning the characteristics, cone dimensions, lesion grade and excision margins of the patients were recorded. RESULTS The median age of the women (n = 61) was 38 years (18-53). LLETZ cone specimens had 36.1% of cervical intraepithelial neoplasia (CIN)2/3 lesion and 13.1% positive margins. Mean cone depth and volume were 10.9 mm and 2.3 cm(3), respectively. Multiple logistic regression for main predictors and after adjustment for age, parity and CIN severity showed that cone volume and length, cone base surface and proportion of excised volume had a significant effect on margin positivity. ROC analysis showed that optimal cut-off for cone volume was 2.1 cm(3) (87.5% sensitivity - 54.7% specificity) or 8.6% of initial cervical volume (75% sensitivity - 75.5% specificity), and for cone length it was 10 mm (100% sensitivity - 52.8% specificity). Optimal cut-off for cone base surface as percentage of ectocervical surface was 32.7% (75% sensitivity - 69.8% specificity). CONCLUSIONS These findings should be taken into consideration when planning the outer boundaries of excision and cervical tissue to be removed so as to achieve oncologically safe limits.

Abstract
OBJECTIVE To study the distribution of collagen in the regenerated cervical tissue after excisional treatment for cervical intraepithelial neoplasia (CIN). DESIGN Cohort study. SETTING A large tertiary teaching hospital in London. POPULATION Women who underwent repeat excisional treatment for treatment failure or persistent CIN. METHODS Eligible women who underwent a repeat excisional treatment for treatment failure, including hysterectomy, between January 2002 and December 2007 in our colposcopy unit were identified by the Infoflex(®) database and SNOMED encoded histopathology database. Collagen expression was assessed using picro-Sirius red stain and the intensity of staining was compared in paired specimens from the first and second treatments. MAIN OUTCOME MEASURE Differences in collagen expression were examined in the paired excisional treatment specimens. RESULTS A total of 17 women were included. Increased collagen expression in the regenerated cervical tissue of the second cone compared with the first cone was noted in six women, decreased expression was noted in five women, and the pattern of collagen distribution was equivocal in six women. CONCLUSION There is no overall change in collagen distribution during regeneration following excisional treatment for CIN.
