Should patients with mild atypia in a cervical smear be referred for colposcopy?

Significant premalignant disease of the cervix was found in 37% of women referred to a colposcopy clinic because of a smear that showed no more than mildly atypical cells, and in 49% of women whose smears showed mild dyskaryosis. This did not seem to be related to the number of times the abnormal smear had been repeated and was not confined to patients whose smears had been reported by only one laboratory. In another group of 102 women whose first abnormal smear was graded as atypical: 10 had cervical intraepithelial neoplasia; 9 still had abnormal smears and 27 had been lost to follow-up, possibly because the potential importance of this finding was not recognised by the doctor to whom the smear report had been returned. Women with midly atypical or mildly dyskaryotic smears are at considerable risk of having cervical intraepithelial neoplasia. All patients with a smear report showing dyskaryosis of any degree of severity should be referred for colposcopy. Those with atypical cytology should be referred for colposcopy if a second smear, repeated after 3 months, is not normal.

Evaluation of colposcopy in the postmenopausal woman.

Cytology, colposcopy and histology findings in 121 postmenopausal and 120 premenopausal women referred to the Oxford colposcopy clinic were compared; 88% of postmenopausal and 69% of premenopausal women were referred by their general practitioners. Cervical smear reports, within the preceding 5 years, were available for 21% of the postmenopausal and 54% of the premenopausal women. Colposcopic assessment was technically unsatisfactory in 53% of the postmenopausal women because the transformation zone was not completely visible, this contributed to a cone biopsy rate of 71% in this group. Only 17% of postmenopausal women with cervical intraepithelial neoplasia (CIN) were managed with local ablative techniques compared with their use in 61% premenopausal patients overall and in over 70% of the women under 35 years. Local ablation was used in 10 of 14 women using hormone replacement therapy. The cytological false negative rate for postmenopausal Papanicolaou class III, IV and V smears was 9% but for persistent class II inflammatory smears it was 43%. Nine of 23 postmenopausal women with persistent inflammatory dyskariosis despite antibiotic or antifungal treatment were found to have colposcopic appearances of CIN and four had microinvasion or invasion. Colposcopy revealed probable microinvasive or invasive disease in 17 postmenopausal women, seven of whom had class II or III cytology.

The effect of directed biopsy on the atypical cervical transformation zone: assessed by digital imaging colposcopy.

OBJECTIVE: To determine the effect of directed punch biopsy trauma on the natural history of atypical cervical transformation zones. DESIGN: A prospective randomised clinical trial. SETTING: Academic Unit colposcopy clinics in Birmingham. PARTICIPANTS: One hundred and eighty women attending the colposcopy clinics were recruited over an 18 month period, of which 161 were eligible for analysis. METHODS: Three-way randomisation of patients into 1. no biopsy, 2. central biopsy and 3. peripheral biopsy groups. Quantitative assessment of the change in surface area and severity of cervical intra-epithelial neoplasia (CIN) lesions in each group measured six weeks apart using digital imaging colposcopy. RESULTS: No significant difference in change in lesion size (P = 0.40) was noted in the three treatment groups. Results suggest that the severity of the lesion was underestimated by the peripheral biopsy. CONCLUSIONS: The results of this study suggest that directed punch biopsy trauma does not have a significant effect on the immediate natural history of CIN. No statistically significant differences were found in lesion size whether biopsy was employed or not. In addition, the site of biopsy had no influence on the outcome. It appears, therefore, that tissue trauma from punch biopsy and the subsequent inflammatory and wound healing processes do not modify the course of CIN. The regressive changes observed after punch biopsy in previous natural history studies are probably not a result of the initial inflammatory response to biopsy trauma and subsequent re-epithelialisation with normal cells, but may result from processes that continue long after tissue repair is completed.

An audit of standards and quality in a teaching hospital colposcopy clinic.

The National Health Service Cervical Screening Programme has issued minimum standards for a colposcopy service that facilitates audit. We have looked at the performance of a teaching hospital colposcopy service by analysing the case notes of 639 women who underwent large loop excision of the transformation zone over a nine-month period in 1995. We found delays in patient assessment and communication of results. There was overtreatment, particularly at first visit, and an excessive number of treatments were performed under general anaesthesia. A worrying number of women failed to have a follow up smear performed, but in those that did we found a reassuring treatment success rate. Our findings led to changes in the structure and functioning of the colposcopy clinic that should improve the detection of significant disease and improve the timeliness of diagnosis and the speed with which we communicate results.

Anxiety levels in women attending colposcopy clinics for treatment for cervical intraepithelial neoplasia: a randomised trial of written and video information.

OBJECTIVE: To assess the effectiveness of video information in reducing the level of anxiety in women attending Colposcopy clinics. DESIGN: An observational study followed by a randomised trial. SETTING: Colposcopy Clinic, Royal Free Hospital, London. PARTICIPANTS: Between April and December 1999, all new referrals to the clinic with a cervical smear showing moderate or severe dyskaryosis. MAIN OUTCOME MEASURE: The level of anxiety measured by the Spielberger State Anxiety Inventory. CONCLUSION: Women attending colposcopy clinics for either diagnosis or treatment, experience a high level of anxiety. The highest levels occur in women attending a one-stop see and treat clinic. The introduction of visual information in the form of an explanatory video prior to attendance significantly reduced anxiety.

A randomised controlled trial to evaluate the effect of self-administered analgesia on women's experience of outpatient treatment at colposcopy.

OBJECTIVE: To evaluate the effect of self-administered isoflurane and desflurane on women's experience of outpatient treatment at colposcopy. DESIGN: A prospective double-blinded randomised controlled trial. SETTING: A colposcopy clinic serving a regional population. POPULATION: Three hundred and ninety-six women scheduled for treatment of cervical intraepithelial neoplasia (CIN) by large loop excision of the transformation zone (LLETZ). METHODS: Self-administration of trial gas during a LLETZ procedure. One hundred and ninety-eight women were randomised to use isoflurane and desflurane and 198 to use placebo. MAIN OUTCOME MEASURES: Patient satisfaction, pain and anxiety. RESULTS: The mean pain score for cervical surgery was significantly lower for women using isoflurane and desflurane (22.4) than the placebo arm (29.6) (P= 0.003). There was no significant difference between arms in anxiety levels before or after treatment. More women using isoflurane and desflurane (78%) reported 'total helpfulness' of the trial gas than those using placebo (67%) (P= 0.012). A subgroup analysis of trial participants classified as anxious by Hospital Anxiety and Depression Scale (HADS) score at recruitment showed that using isoflurane and desflurane significantly increased total treatment acceptability, helpfulness of the gas and willingness to undergo a similar procedure at six-month follow up. CONCLUSION: Satisfaction with outpatient treatment at colposcopy is generally high. The main effect of isoflurane and desflurane evaluated in this trial was to reduce pain. It appeared to be effective for women with clinically significant anxiety and could be offered as an alternative to general anaesthesia.

Is colposcopy needed following laser ablation for dysplasia?

AIMS: To evaluate the effectiveness of cytology and colposcopy in the follow up of women treated by laser CO(2) ablation for cervical intraepithelial neoplasia (CIN). METHODS: A retrospective analysis of 1784 patients with CIN treated with laser CO(2) ablation from 1998 to 2003 at the Royal Women's Hospital, Melbourne. Data were collected prospectively in a computerised colposcopy database utilised in the Dysplasia Unit. RESULTS: There was equal distribution in the study population treated for low-grade intraepithelial neoplasia (LSIL) and high-grade intraepithelial neoplasia (HSIL), with no significant age difference in both groups (mean 27.6 years). The success rate of treatment of LSIL (94%) was similar to that of HSIL (92%). Fifty-seven per cent of all failures occurred within the first year of treatment. Colposcopy was more sensitive in detecting intraepithelial neoplasia (SIL) than cytology, whereas cytology was more specific. No case of cancer was diagnosed on follow up. CONCLUSIONS: CO(2) laser ablation was equally effective in treating different grades of CIN. There is a continuing incidence of recurrent CIN, even up to five years after initial treatment, which suggests that it is necessary for patients to adhere to long-term follow up. The combination of cytology and colposcopic assessment is essential for surveillance of SIL in the initial two years after treatment.

Impact of introduction of colposcopy to a district general hospital.

During the first 18 months of operation of a new colposcopy clinic, established in a district general hospital, 608 women were seen. Most (568 (93.0%] were referred from within the local district, on the whole by their general practitioner. In 466 cases a repeat cervical smear was taken, and all women underwent colposcopic examination together with directed punch biopsy of any abnormal area. Positive cytology was seen in 356 women, but 85 (23.9%) of these were found to have no histological evidence of malignancy or premalignancy and were consequently discharged from the clinic. Cervical intraepithelial neoplasia was confirmed histologically in 379 women, of whom 259 were under 35 and 175 nulliparous. As a result of the use of colposcopy and local destructive methods of treatment only 42 patients (11.1%) were required to undergo cone biopsy. The initial overall incidence of success in the treatment of cervical intraepithelial neoplasia was 86.2% for cone biopsy, 88.5% for diathermy, and 81.1% for laser ablative treatment. Colposcopy has an important role in the management of cervical neoplasia in the district general hospital.

Colposcopy services in the West Midlands region.

A survey of all 72 consultant gynaecologists in the West Midlands region was carried out to determine their views on colposcopy services. All districts provided a colposcopy service and 47 consultants practised colposcopy. The consultants differed considerably in their views on criteria for referring women for investigation after smears. All but one thought that a positive smear result was an indication for immediate referral but whereas 55 thought that women with one or more inflammatory smear should be referred, 17 did not believe this to be necessary. Sixty seven consultants thought a preoperative colposcopic assessment desirable, but 10 had to ration referrals because of limited resources. Four forms of treatment were used: 17 districts had a carbon dioxide laser, eight used low voltage diathermy loop excision, two had only a cold coagulator, and one used only cold cautery. There was widespread dissatisfaction with resources and about the increasing amount of time spent on the service at the expense of other work. Consultants were also concerned about the relevance of much of what was done to the aim of the screening programme--reducing mortality from cervical cancer. Although additional resources are needed in some districts, referral policies, indications for colposcopic assessment, training, choice of treatment, and the value of follow up need to be reviewed if the service is to be improved.

Six years' audit of laboratory workload and rates of referral for colposcopy in a cervical screening programme in three districts.

OBJECTIVE: To determine laboratory workload and rates of referral for colposcopy in a three district cervical screening programme during 1983-9 to assess the feasibility of accommodating call up of all women at risk, recall at three year intervals (now five year intervals), and investigation of women with all degrees of abnormality. DESIGN: Analysis of computerised screening histories dating back to 1977 of women screened in the Avon cervical screening programme. SETTING: Three district health authorities covering the population of Bristol and Weston-super-Mare, comprising 800,000 people, of whom 250,000 were female residents aged 20 to 64. SUBJECTS: 196,977 Women aged 20 to 64 screened in cervical screening programme since 1983. RESULTS: Laboratory workload devoted to follow up of women with abnormalities increased sharply between 1987-8 and 1988-9, with increases of 54% (from 2075 to 3196) in the number of smears for follow up of severe dyskaryosis and invasive cancer, 40% (from 1925 to 2695) for mild and moderate dyskaryosis, and 49% (from 1793 to 2677) for borderline change. The increases were partly explained by the introduction in April 1988 of protocols for follow up and investigation based on guidance in an intercollegiate working party report. The proportion of women with mild and moderate dyskaryosis who were recommended for referral for colposcopy increased steadily from 9.9% in 1983-4 to 79.9% in 1988-9, and for borderline change the proportions were 3.5% and 13.6% respectively. Of all women tested in 1988-9, referral for colposcopy was recommended in 3%. CONCLUSIONS: The increase in laboratory follow up work identified, if it continued, could result in half of existing laboratory capacity in Avon being devoted to follow up work by 1993, with little prospect of maintaining call, recall, and quality control. Investigation of all women with minor cytological abnormalities is neither justifiable nor sustainable and will undermine the benefits of screening by increasing the rate of false positive results and the financial costs.

Effect of introduction of colposcopy into a district general hospital.

Management of cervical intra-epithelial neoplasia, in a district general hospital, was examined for two 22-month periods before and after the introduction of colposcopy. This technique enables the clinician to evaluate the extent and severity of pre-malignant change, and makes treatment, using less radical destructive techniques, possible. The method of conservative treatment in this hospital was diathermy, and the cure rate of cases so treated was 97%. The use of diathermy treatment resulted in a 75% reduction in the incidence of cone biopsy in women below the age of 40 years. A further advantage of colposcopy has been recognized, which is that some women with "mild or moderate changes" are discovered to have more severe lesions, and receive appropriate treatment without delay. It follows that all patients with an abnormal smear should be referred for colposcopy, unless there is an obvious local cause of the abnormality, such as easily treatable infection, and that the post-treatment smear reverts to normal. In this hospital the cost of establishing a colposcopic service was low, and the cost benefits, as well as the improved management of cervical intraepithelial neoplasia suggests that the service should be introduced in all district general hospitals.

Factors influencing default at a hospital colposcopy clinic.

OBJECTIVE: To identify factors reducing compliance at diagnosis, treatment, and review stages among women referred with abnormal cervical smears to a hospital colposcopy clinic. DESIGN: Retrospective analysis of sociodemographic data from hospital notes of the attenders and defaulters during one year (1989-90) and prospective collection of information by structured interviews of a sample of defaulters and attenders during five months (May-September 1990). SETTING: One hospital colposcopy clinic. PATIENTS: 238 women defaulting on two consecutive occasions and 188 attending regularly (retrospective analysis) and a subset of 40 defaulters and 24 attenders (interview sample). MAIN MEASURES: Sociodemographic data and interview responses about attitudes, behaviour, choice, accessibility cultural understanding, communications, and emotional response. RESULTS: 22 (12%) women defaulted at diagnosis, 24(13%) at treatment, 39(21%) at the first check up after treatment, and 84(45%) at the review stage; 19(10%) defaulted from the first check up after diagnostic examination revealed no need for treatment. Age and social class differed between the two groups. 181(76%) defaulters were under 30 compared with 91(48%) attenders; 14(6%) compared with 41(23%) were over 40(p < 0.001). The proportion of women in social classes 4 and 5 was 33%(20/60) for defaulters and 21%(25/120) for attenders (p < 0.05) and unemployed was 66%(158/238) and 36%(68/188) respectively. 63(28%) defaulters were pregnant compared with 11(6%) attenders (p < 0.001). More defaulters came from gynaecology or antenatal clinics. Most defaulters (93%) had child care responsibilities and they knew and understood less about colposcopy. Their explicit reasons for defaulting included child care commitments and fear and their implicit reasons lack of understanding, inaccessibility of information, and staff attitudes. CONCLUSIONS: Compliance may be improved by promoting women's understanding of treatment and encouraging health professionals to develop a service more sensitive to the various needs of women in different socioeconomic groups.

Quality control for colposcopy in the Florence screening program for cervical cancer.

The authors report on the quality control for colposcopy adopted in the Florence District screening program. The sensitivity of colposcopy was determined on all cases of CIN III recorded in the local cancer registry in a four-year period. However although this showed that a centralized colposcopic clinic employing a limited number of expert operators is superior to the performance of colposcopy in private practice, such a parameter was impractical for further routine quality control since differences among operators were too small and statistically insignificant. Other parameters for quality control were chosen, namely a) the rate of colposcopically directed biopsies performed, b) the detection rate of CIN II or more severe lesions, and c) the positive predictive value of a directed biopsy for CIN II or more severe lesions. Analysis of these indicators after stratification by cytologic report allows the identification of those operators who need additional training and provides useful information for colposcopists to optimize their diagnostic and operative criteria.

The role of early colposcopy in the management of females with first episode anogenital warts.

212 females attending a genitourinary medicine (GUM) clinic with first episode anogenital warts were screened by cervical cytology and colposcopy/histology for the presence of cervical epithelial abnormalities in keeping with infection by the human papillomavirus (HPV infection) and/or cervical intraepithelial neoplasia (CIN). The prevalence of cervical epithelial abnormalities detected by cervical cytology alone was 32%, rising to 56% after colposcopic examination. However, the majority of cervical lesions detected by colposcopy alone were of low grade (HPV infection and/or CIN I). Histologically-confirmed high grade cervical lesions (CIN II or CIN III) were detected more frequently in those females in whom cervical cytological examination indicated dyskaryosis in keeping with any grade of CIN, compared to females without dyskaryotic changes on cervical smear (P < 0.05, chi-squared test with Yates' correction). Early colposcopy is indicated for females with anogenital warts in the presence of a cervical smear showing dyskaryosis in keeping with any grade of CIN, because of the statistically significant increased risk of detecting a potentially progressive high grade cervical lesion. In females without dyskaryotic changes on cervical smear, the value of early colposcopy is uncertain and warrants larger more long-term trials.

Screening for cervical abnormalities in women with anogenital warts in an STD clinic: an inappropriate use of colposcopy.

An audit of the use of colposcopy in women with anogenital warts was performed. Fifty women attending a clinic for sexually transmitted diseases in a District General Hospital with anogenital warts were examined by cervical cytology and colposcopy for cervical infection by human papillomavirus (HPV) or epithelial abnormality indicating cervical intraepithelial neoplasia (CIN) or both. Collated results showed a high prevalence of both conditions in these 50 women; 20 (40%) had evidence of cervical infection by HPV and 11 (22%) epithelial abnormalities consistent with CIN 1 or 2. However, neither CIN 3 nor invasive disease was detected. Colposcopy in this setting was shown to be a specific but insensitive tool and its role in the routine management of women with anogenital warts at our institution is not warranted.

Anxiety and the colposcopy experience.

The purpose of this study was to explore the anxiety of an abnormal Papanicolaou (Pap) result, the need for colposcopy, and the colposcopic examination experienced by first-time colposcopy clients. Spielberger's State-Trait Anxiety Inventory (STAI) and a Woman's Profile were administered to 149 women who had abnormal Pap smears necessitating colposcopy. The results confirm that this experience evokes anxiety. Younger women who knew less and had concurrent stressors in their lives were most anxious. Women identified ways that health professionals could be more helpful in alleviating their anxiety. Their suggestions included the provision of more information and an opportunity for personal contact with a health professional.

Audit of cervical screening and colposcopy in HIV-positive women at a central London teaching hospital.

The purpose of this audit was to assess the prevalence of cervical pathology and clinical outcome in HIV-infected women as well as adherence to local screening guidelines. As there are no national screening guidelines for HIV-positive patients, recommendations vary widely. At St Stephen's Centre, these included annual cytology and a baseline colposcopy. We audited this recommendation by a clinical notes review using a computer database. Analysis was performed using Statistical Package for Social Sciences (SPSS). Two hundred and twenty-two patients were eligible for analysis, their mean age was 33.6 years, median CD4 count was 239 and median viral load was 7836 RNA copies. Cytology was undocumented in 72 women (32.4%), while overall 42 (28%) smears of the remaining 150 patients were abnormal: borderline 17.3%, mild dyskaryosis 4.6%, moderate dyskaryosis 4%, severe dyskaryosis 2%. The results were normal in 64% and unsatisfactory in 4.6%. Colposcopy was offered to 93 (42%) women who attended at least once in 71 cases (32%). Thirty-one women had biopsies taken (43.6% of all colposcopies). Twenty-four (77.4%) had a histology more severe than HPV and 15 (48.4%) more severe than cervical intraepithelial neoplasia (CIN)-1. Overall, 49.7% had management not complying with the guidelines. This audit led to a critical literature review and of local screening guidelines. A computer aided reminder program has now been installed and re-auditing of the management of HIV-positive women is planned.

Cervical cancer. 2: Colposcopy, treatment and patient education.

In the first article in this two-part series (Vol 8(11): 730-34) the issue of cervical screening and the cervical smear test was described and discussed. This article looks at colposcopy. When a woman receives an abnormal smear test result, she will often require further examination of the cervix in order to identify the degree and area of dyskaryosis. Colposcopy can often provoke feelings of fear and anxiety in women and the nurse must help to alleviate these fears and anxieties. Colposcopy and cervical intraepithelial neoplasia are discussed and the treatment (if any) is outlined.
