Health-related quality of life in women after colposcopy: results from a longitudinal patient survey.

BACKGROUND: Information concerning the health-related quality-of-life (HRQoL) consequences of colposcopy is limited, particularly over time. In a longitudinal study, we investigated women's HRQoL at 4, 8 and 12 months post colposcopy and the factors associated with this. METHODS: Women attending colposcopy at two large hospitals affiliated with the national screening programme in Ireland were invited to complete questionnaires at 4, 8 and 12 months post colposcopy. HRQoL was measured using the EQ-5D-3L and compared across a range of socio-demographic, clinical and attitudinal variables. A mixed-effects logistic multivariable model was employed to investigate associations between these variables and low HRQoL. RESULTS: Of 584 women initially recruited, 429, 343 and 303 completed questionnaires at 4, 8 and 12 months, respectively. The mean overall HRQoL score for the sample across all time points was 0.90 (SD 0.16). Approximately 18% of women experienced low HRQoL at each of the three time points. In multivariable testing, over the entire 12-month follow-up period, non-Irish nationals (OR 8.99, 95% CI 2.35-34.43) and women with high-grade referral cytology (OR 2.78, 95% CI 1.08-7.13) were at higher odds of low HRQoL. Women who were past (OR 0.20, 95% CI 0.07-0.58) or never (OR 0.42, 95% CI 0.16-1.12) smokers were at lower odds of low HRQoL than current smokers. As women's satisfaction with their healthcare increased their odds of experiencing low HRQoL fell (OR per unit increase 0.51, 95% CI 0.34-0.75). CONCLUSIONS: Women's HRQoL did not change over the 12 months post colposcopy, but some subgroups of women were at higher risk of experiencing low HRQoL. These subgroups may benefit from additional support.

Physical after-effects of colposcopy and related procedures, and their inter-relationship with psychological distress: a longitudinal survey.

OBJECTIVE: To estimate prevalence of post-colposcopy physical after-effects and investigate associations between these and subsequent psychological distress. DESIGN: Longitudinal survey. SETTING: Two hospital-based colposcopy clinics. POPULATION: Women with abnormal cytology who underwent colposcopy (±related procedures). METHODS: Questionnaires were mailed to women 4, 8 and 12 months post-colposcopy. Details of physical after-effects (pain, bleeding and discharge) experienced post-colposcopy were collected at 4 months. Colposcopy-specific distress was measured using the Process Outcome-Specific Measure at all time-points. Linear mixed-effects regression was used to identify associations between physical after-effects and distress over 12 months, adjusting for socio-demographic and clinical variables. MAIN OUTCOME MEASURES: Prevalence of post-colposcopy physical after-effects. Associations between the presence of any physical after-effects, awareness of after-effects, and number of after-effects and distress. RESULTS: Five-hundred and eighty-four women were recruited (response rate = 73, 59 and 52% at 4, 8 and 12 months, respectively). Eighty-two percent of women reported one or more physical after-effect(s). Multiple physical after-effects were common (two after-effects = 25%; three after-effects = 25%). Psychological distress scores declined significantly over time. In adjusted analyses, women who experienced all three physical after-effects had on average a 4.58 (95% CI: 1.10-8.05) higher distress scored than those who experienced no after-effects. Women who were unaware of the possibility of experiencing after-effects scored significantly higher for distress during follow-up. CONCLUSIONS: The prevalence of physical after-effects of colposcopy and related procedures is high. The novel findings of inter-relationships between awareness of the possibility of after-effects and experiencing multiple after-effects, and post-colposcopy distress may be relevant to the development of interventions to alleviate post-colposcopy distress. TWEETABLE ABSTRACT: Experiencing multiple physical after-effects of colposcopy is associated with psychological distress.

Large loop versus straight-wire excision of the transformation zone for treatment of cervical intraepithelial neoplasia: a randomised controlled trial of electrosurgical techniques.

OBJECTIVE: To compare two electrosurgical techniques, straight-wire excision of transformation zone (SWETZ) with large loop excision of transformation zone, as a cone procedure (LLETZ-cone), for the treatment of cervical intraepithelial neoplasia (CIN), when disease is present at the cervical canal. DESIGN: Randomised controlled trial. SETTING: Two public hospitals, one in Rio de Janeiro, Brazil and one in Dublin, Ireland. POPULATION: One hundred and three women with indication to treat CIN located at cervical canal. METHODS: Women were randomised to receive LLETZ-cone or SWETZ. OUTCOMES: Main outcome was the incidence of complete excision of disease at endocervical margin of the surgical specimen. Secondary outcomes were complete excision at ectocervical and stromal margins, time to complete the procedure, specimen fragmentation, blood loss and death after 1 year. RESULTS: Fifty-two women were allocated to LLETZ-cone and 51 to SWETZ. Ten women were lost for main outcome because of damaged specimens. Forty-two women in the LLETZ-cone group had free endocervical margin versus 43 women in the SWETZ group (relative risk 1.04, 95% confidence interval [95% CI] 0.87-1.25; P = 0.64). For secondary outcomes related to margins, we observed a relative risk of 1.15 (95% CI 0.95-1.39; P = 0.15) for ectocervical free margin. For free stromal margin, the relative risk was 1.07 (95% CI 0.89-1.29; P = 0.47). No death was observed. CONCLUSIONS: This study was inconclusive; SWETZ and LLETZ-cone were equally effective to treat endocervical disease, with no difference in protecting against margin involvement. Higher, but not severe, blood loss and longer surgical time were observed in the SWETZ group.

'I don't care whether it's HPV or ABC, I just want to know if I have cancer.' Factors influencing women's emotional responses to undergoing human papillomavirus testing in routine management in cervical screening: a qualitative study.

OBJECTIVE: To explore emotional responses, and predictors of negative reactions, among women undergoing human papillomavirus (HPV) tests in routine clinical practice. DESIGN: Exploratory qualitative interview study. SETTING: A large busy colposcopy clinic in a Dublin hospital. SAMPLE: Twenty-seven women who had had an HPV DNA test in the previous 6 months following one or more low-grade cytology tests or treatment for cervical intraepithelial neoplasia (CIN). METHODS: In-depth semi-structured interviews were conducted. Interview transcripts were analysed using a thematic approach (Framework Analysis). MAIN OUTCOME MEASURES: Women's emotional responses and predictors of negative emotional reactions. RESULTS: For most women, having a test for high-risk HPV types generated little negative or positive emotional impact. Adverse emotional responses related to HPV infection rather than testing. Factors that influenced whether women experienced negative emotional responses were: concerns over abnormal cytology or diagnosis of CIN; HPV knowledge; awareness of HPV being sexually transmitted; awareness of HPV prevalence; and HPV information needs. Women's concerns about abnormal cytology/CIN dominated all other issues. CONCLUSIONS: These qualitative data suggest that in the context of follow up of abnormal cytology or treatment for CIN, the emotional impact of HPV testing may be modest: women's primary concerns at this time relate to abnormal cytology/CIN.

Accuracy of detection of high-grade cervical intraepithelial neoplasia using electrical impedance spectroscopy with colposcopy.

OBJECTIVE: To determine if electrical impedance spectroscopy (EIS) improves the diagnostic accuracy of colposcopy when used as an adjunct. DESIGN: Prospective, comparative, multi-centre clinical study. SETTING: Three colposcopy clinics: two in England and one in Ireland. POPULATION: Women referred with abnormal cytology. METHODS: In phase 1, EIS was assessed against colposcopic impression and histopathology of the biopsies taken. In phase 2, a probability index and cut-off value for the detection of high-grade cervical intraepithelial neoplasia (HG-CIN, i.e. grade CIN2+) was derived to indicate sites for biopsy. EIS data collection and analyses were performed in real time and blinded to the clinician. The phase-2 data were analysed using different cut-off values to assess performance of EIS as an adjunct. MAIN OUTCOME MEASURE: Histologically confirmed HG-CIN (CIN2+). RESULTS: A total of 474 women were recruited: 214 were eligible for analysis in phase 1, and 215 were eligible in phase 2. The average age was 33.2 years (median age 30.3 years, range 20-64 years) and 48.5% (208/429) had high-grade cytology. Using the cut-off from phase 1 the accuracy of colposcopic impression to detect HG-CIN when using EIS as an adjunct at the time of examination improved the positive predictive value (PPV) from 78.1% (95% CI 67.5-86.4) to 91.5%. Specificity was also increased from 83.5% (95% CI 75.2-89.9) to 95.4%, but sensitivity was significantly reduced from 73.6% (95% CI 63.0-82.5) to 62.1%, and the negative predictive value (NPV) was unchanged. The positive likelihood ratio for colposcopic impression alone was 4.46. This increased to 13.5 when EIS was used as an adjunct. The overall accuracy of colposcopy when used with EIS as an adjunct was assessed by varying the cut-off applied to a combined test index. Using a cut-off set to give the same sensitivity as colposcopy in phase 2, EIS increased the PPV to detect HG-CIN from 53.5% (95% CI 45.0-61.8) to 67%, and specificity increased from 38.5% (95% CI 29.4-48.3) to 65.1%. NPV was not significantly increased. Alternatively, applying a cut-off to give the same specificity as colposcopy alone increased EIS sensitivity from 88.5% (95% CI 79.9-94.4) to 96.6%, and NPV from 80.8% (95% CI 67.5-90.4) to 93.3%. PPV was not significantly increased. The receiver operator characteristic (ROC) to detect HG-CIN had an area under the curve (AUC) of 0.887 (95% CI 0.840-0.934). CONCLUSIONS: EIS used as an adjunct to colposcopy improves colposcopic performance. The addition of EIS could lead to more appropriate patient management with lower intervention rates.

Image assessment of cervical dimensions after LLETZ: a prospective observational study.

OBJECTIVE: To assess the impact of large loop excision of the transformation zone (LLETZ) for cervical intraepithelial neoplasia (CIN) on cervical morphology as assessed by three-dimensional ultrasound. DESIGN: Prospective observational study. SETTING: University Hospital in Dublin. POPULATION: Women with CIN who underwent an LLETZ procedure. METHODS: All 106 participants had a three-dimensional transvaginal ultrasound scan (3DTVS) performed immediately before and 6 months after LLETZ. The excised LLETZ specimen dimensions were also recorded. Blind analysis of the images was performed. The volume of the uterus and cervix was documented. MAIN OUTCOME MEASURES: The relationship between the extirpated LLETZ dimensions and subsequent cervical and uterine biometry, as assessed by 3DTVS. RESULTS: LLETZ induced a statistically significant reduction in both the length (mean, -0.46 cm; P < 0.001) and the volume (-6.12 cm(3) ; P < 0.001) of the uterus, and in the volume of the cervix (-1.60 cm(3) ; P < 0.001). The volume of the excised specimen had a significant impact on the reduction of the length of the uterus (ß, -0.038; P = 0.012), the volume of the uterus (ß, -0.791; P = 0.036) and the volume of the cervix (ß, -0.121; P = 0.046). The circumference of the excised specimen appeared to have a significant impact on the length (ß, -0.016; 95% CI, -0.028 to -0.003; P = 0.013) and volume (ß, -0.413; 95% CI, -0.719 to -0.107; P = 0.009) of the uterus 6 months after LLETZ. CONCLUSIONS: The volume of tissue removed at LLETZ is related to the subsequent cervical volume, as well as the uterine length and volume, 6 months after the procedure.

The thickness and volume of LLETZ specimens can predict the relative risk of pregnancy-related morbidity.

OBJECTIVE: The aim of this study was to determine if the individual physical characteristics of the extirpated transformation zone after large loop excision of the transformation zone (LLETZ) might predict the relative risk of adverse obstetric outcome, specifically preterm labour (PTL). DESIGN: A retrospective observational study. SETTING: University teaching hospital in Dublin (Coombe Women & Infants University Hospital, CWIUH). POPULATION: Women who had LLETZ treatment for cervical intraepithelial neoplasia (CIN) in the colposcopy service between 1999 and 2002, and who subsequently had a pregnancy at the CWIUH. METHODS: Case records and histology reports for eligible women were examined. Age, parity, smoking history, pregnancy complications and CIN grade were recorded. Exclusion criteria were age >42 years, previous treatment for CIN, previous premature labour or twin pregnancies. The Student's t-test, Mann-Whitney U-test, analysis of variants (ANOVA) and logistic regression were employed to analyse the data. MAIN OUTCOME MEASURES: Gestational age at birth, PTL (i.e. <37 weeks of gestation) and miscarriage rate (<24 weeks of gestation). RESULTS: Out of 1808 women who underwent LLETZ treatment, a total of 353 women were identified who subsequently had a pregnancy at the CWIUH, with 321 being eligible for inclusion in the study. Of these, 76.3% delivered at term, 9.1% delivered at <37 weeks of gestation and 14.6% miscarried at <24 weeks of gestation. There was a three-fold increase in the risk of PTL if the excision volume exceeded 6 cm(3) (RR = 3.00; 95% CI 1.45-5.92), or when the thickness of the excised tissue was greater than 12 mm (RR = 2.98; 95% CI 1.27-7.01). The time interval between LLETZ and pregnancy did not appear to have an effect on PTL rates. We found no association between the grade of CIN and the risk of PTL. CONCLUSIONS: This study reveals that the thickness and the total volume of the excised transformation zone are associated with an increased risk of PTL. Excisions thicker than 1.2 cm and larger than 6 cm(3) carry a three times greater risk for PTL.

Compliance with follow up cytology after discharge from the colposcopy clinic.

Cervical cancer represents the second common cancer in women and is a major public health issue in Ireland and worldwide. Despite appropriate treatment of precancerous lesions, women with dysplasia are at relatively increased risk, and require follow up. We aimed to evaluate the compliance rate with follow up cytology advice given to patients discharged from the colposcopy clinic and to identify predictive factors for poor compliance. This is a retrospective cohort study of patients initially managed in our institution in 2001. Patients were evaluated for adherence with the recommendations received at the time of discharge from the clinic. Of the 116 women that were initially contacted, 100 agreed to participate in the study (86% response rate). Sixty women (60%) were entirely compliant. While older patients (> 40 years) were significantly less likely to show complete compliance (OR: 0.12; 950/ Cl: 0.02-0.58; p = 0.009).

Proportion of excision and cervical healing after large loop excision of the transformation zone for cervical intraepithelial neoplasia.

OBJECTIVE: To determine how the proportion of the cervical volume excised affects cervical regeneration. DESIGN: Prospective observational study. SETTING: University Hospital. POPULATION: Women planning to undergo excisional treatment for cervical intraepithelial neoplasia who wish to have future pregnancies. METHODS: The cervical volume (and dimensions) is calculated with magnetic resonance imaging (MRI) before treatment. The volume (and dimensions) of the cone is assessed before fixation by a volumetric tube and a ruler; the percentage (%) of excision is computed. Cervical regeneration is estimated by repeat MRI at 6 months. MAIN OUTCOME MEASURES: Cervical regeneration in relation to proportion of excision. Statistical analysis was performed by box plots and analysis of variance. RESULTS: A total of 48 women have been recruited; 29 have completed 6 months follow up. Both the total cervical volume (from MRI) before treatment and the volume of the excised/ablated cone varied substantially. The estimated proportion of excision varied significantly between 4% and 39% (median 11%). Multivariate linear regression revealed that the proportional deficit at 6 months post-treatment was determined mainly by the proportion of the excised volume. CONCLUSIONS: Careful assessment of risks and benefits of treatment is essential when deciding to treat women who wish to have future pregnancies. Assessment of the proportion of the cervical volume and length excised might identify those that need further surveillance during future pregnancy.

The treatment of CIN: what are the risks?

The treatment of CIN: what are the risks?The treatment of squamous cervical intraepithelial neoplasia is to remove or destroy the transformation zone (TZ). It is likely that no method of treatment is superior to another if it is performed properly and the limited available evidence supports this view. The significant advantages of excision (simplicity, cost, outpatient procedure, histological examination of the entire TZ) mean that treatment thresholds may have lowered over the last decade. Long-term pregnancy-related morbidity associated with excision has been reported recently. The evidence would suggest that this increase equates to a genuine increase in serious adverse outcome for cone biopsy but not large loop excision of the transformation zone (LLETZ). The available data also point to an increase in both incomplete excision and premature labour associated with the excision of large endocervical TZs. The clinical implications arising from this are firstly that women with large type 2 and 3 TZs need appropriate counselling before treatment and that the threshold for treating young women with mild abnormalities needs review.

European guidelines for clinical management of abnormal cervical cytology, part 2.

The current paper presents the second part of chapter 6 of the second edition of the European Guidelines for Quality Assurance in Cervical Cancer Screening. The first part of the same chapter was published in a previous issue (Cytopathology 2008;19:342-54). This part provides guidance on how to manage and treat women with histologically confirmed cervical intraepithelial neoplasia. The paper describes the characteristics, indications and possible complications of excisional and ablative treatment methods. The three options to monitor the outcome after treatment (repeat cytology, HPV testing and colposcopy) are discussed. Specific recommendations for particular clinical situations are provided: pregnancy, immuno-suppression, HIV infection, post-menopause, adolescence and cyto-colpo-histological disparity. The paper ends with recommendations for quality assurance in patient management and some general advice on how to communicate screening, diagnosis and treatment results to the woman concerned. Finally, a data collection form is attached.

European guidelines for quality assurance in cervical cancer screening: recommendations for clinical management of abnormal cervical cytology, part 1.

The current paper presents the first part of Chapter 6 of the second edition of the European Guidelines for Quality Assurance in Cervical Cancer Screening. It provides guidance on how to manage women with abnormal cervical cytology. Throughout this article the Bethesda system is used for cervical cytology terminology, as the European guidelines have recommended that all systems should at least be translated into that terminology while cervical intraepithelial neoplasia (CIN) is used for histological biopsies (Cytopathology 2007; 18:213-9). A woman with a high-grade cytological lesion, a repeated low-grade lesion or with an equivocal cytology result and a positive human papillomavirus (HPV) test should be referred for colposcopy. The role of the colposcopist is to identify the source of the abnormal cells and to make an informed decision as to whether or not any treatment is required. If a patient requires treatment the colposcopist will decide which is the most appropriate method of treatment for each individual woman. The colposcopist should also organize appropriate follow-up for each woman seen. Reflex testing for high-risk HPV types of women with atypical squamous cells (ASC) of undetermined significance with referral for colposcopy of women who test positive is a first option. Repeat cytology is a second possibility. Direct referral to a gynaecologist should be restricted to special circumstances. Follow-up of low-grade squamous intraepithelial lesion is more difficult because currently there is no evidence to support any method of management as being optimal; repeat cytology and colposcopy are options, but HPV testing is not sufficiently selective, unless for older women. Women with high-grade squamous intraepithelial lesion (HSIL) or atypical squamous cells, cannot exclude HSIL (ASC-H) should be referred without triage. Women with glandular lesions require particular attention. In a subsequent issue of Cytopathology, the second part of Chapter 6 will be presented, with recommendations for management and treatment of histologically confirmed intraepithelial neoplasia and guidance for follow-up of special cases such as women who are pregnant, postmenopausal or immunocompromised.

Perinatal mortality and other severe adverse pregnancy outcomes associated with treatment of cervical intraepithelial neoplasia: meta-analysis.

OBJECTIVE: To assess the relative risk of perinatal mortality, severe preterm delivery, and low birth weight associated with previous treatment for precursors of cervical cancer. DATA SOURCES: Medline and Embase citation tracking from January 1960 to December 2007. Selection criteria Eligible studies had data on severe pregnancy outcomes for women with and without previous treatment for cervical intraepithelial neoplasia. Considered outcomes were perinatal mortality, severe preterm delivery (<32/34 weeks), extreme preterm delivery (<28/30 weeks), and low birth weight (<2000 g, <1500 g, and <1000 g). Excisional and ablative treatment procedures were distinguished. RESULTS: One prospective cohort and 19 retrospective studies were retrieved. Cold knife conisation was associated with a significantly increased risk of perinatal mortality (relative risk 2.87, 95% confidence interval 1.42 to 5.81) and a significantly higher risk of severe preterm delivery (2.78, 1.72 to 4.51), extreme preterm delivery (5.33, 1.63 to 17.40), and low birth weight of <2000 g (2.86, 1.37 to 5.97). Laser conisation, described in only one study, was also followed by a significantly increased chance of low birth weight of <2000 g and <1500 g. Large loop excision of the transformation zone and ablative treatment with cryotherapy or laser were not associated with a significantly increased risk of serious adverse pregnancy outcomes. Ablation by radical diathermy was associated with a significantly higher frequency of perinatal mortality, severe and extreme preterm delivery, and low birth weight below 2000 g or 1500 g. CONCLUSIONS: In the treatment of cervical intraepithelial neoplasia, cold knife conisation and probably both laser conisation and radical diathermy are associated with an increased risk of subsequent perinatal mortality and other serious pregnancy outcomes, unlike laser ablation and cryotherapy. Large loop excision of the transformation zone cannot be considered as completely free of adverse outcomes.

Management of minor cervical cytological abnormalities: a systematic review and a meta-analysis of the literature.

BACKGROUND: A significant number of women are diagnosed with a low grade cytological abnormality on cervical screening. Many authorities recommend surveillance as spontaneous regression might occur. However, protracted attendance for cytological follow-up decreases with time and might put some women at risk of developing invasive disease. The aim of this review was to assess management options for women with minor cervical disease. METHODS: An electronic literature search was conducted. All randomised controlled studies comparing immediate colposcopy to cytological surveillance in women with cervical atypia/borderline nuclear changes or low-grade lesions were included. The main outcomes studied were the default rates from the colposcopy clinic and the histological status of biopsies within immediate management protocols compared to biopsies taken on completion of surveillance. Pooled relative risks and 95% confidence intervals were calculated using a random-effect model and inter-study heterogeneity was assessed with Cochrane's Q-test. RESULTS: Three randomised controlled trials identified from the literature search with different surveillance periods were combined. The analysis revealed that compliance with follow-up declines over time and reaches significance at the end of 24 months of surveillance (RR: 74.10 [10.36, 529.79]). There was a significantly higher incidence of HPV and CIN 1 in those women referred to immediate colposcopy/treatment compared to those at the end of 24 months surveillance period (32% vs 21%) (RR 1.49, 95% CI 1.17-1.90) and (21% vs 8%) (RR 2.58, 95% CI 1.69-3.94), respectively, possibly explained by spontaneous regression of clinically non-important lesions. Finally, there was no significant difference in the incidence of CIN2 or worse at initial colposcopy compared with the observation group (24 months) (RR 1.72, 95% CI 0.85-3.48). CONCLUSION: Cytological surveillance puts women at risk as many show poor compliance and such women might have occult high grade abnormalities. A general policy should be immediate colposcopy for all women after a single low grade cervical smear.

Variations in policies for management of the third stage of labour and the immediate management of postpartum haemorrhage in Europe.

BACKGROUND: The EUropean Project on obstetric Haemorrhage Reduction: Attitudes, Trial, and Early warning System (EUPHRATES) is a set of five linked projects, the first component of which was a survey of policies for management of the third stage of labour and immediate management of postpartum haemorrhage following vaginal birth in Europe. OBJECTIVES: The objectives were to ascertain and compare policies for management of the third stage of labour and immediate management of postpartum haemorrhage in maternity units in Europe following vaginal birth. DESIGN: Survey of policies. SETTING: The project was a European collaboration, with participants in 14 European countries. SAMPLE: All maternity units in 12 countries and in selected regions of two countries in Europe. METHODS: A postal questionnaire was sent to all or a defined sample of maternity units in each participating country. MAIN OUTCOME MEASURES: Stated policies for management of the third stage of labour and the immediate management of postpartum haemorrhage. RESULTS: Policies of using uterotonics for the management of the third stage were widespread, but policies about agents, timing, clamping and cutting the umbilical cord and the use of controlled cord traction differed widely. For immediate management of postpartum haemorrhage, policies of massaging the uterus were widespread. Policies of catheterising the bladder, bimanual compression and in the choice of drugs administered were much more variable. CONCLUSIONS: Considerable variations were observed between and within countries in policies for management of the third stage of labour. Variations were observed, but to a lesser extent, in policies for the immediate management of postpartum haemorrhage after vaginal birth. In both cases, policies about the pharmacological agents to be used varied widely.
