Implications of gynaecological abnormalities in pre-selection criteria for cervical screening: preliminary evaluation of 3602 subjects in South India

Early detection and eradication of cervical cancer and its precursor lesions through organized mass cytological screening programmes have recently gained considerable attention in developing countries. Strategies for both cost saving and effective implementation are however required for mass cervical screening in developing countries. In an early cancer detection programme conducted in South India, we analysed cytological abnormalities in 3602 women and correlated the results with other factors, including age, gynaecological complaints, number of years of married life and parity to see if pre-selection for cytologic screening was possible. Only lower grades of dysplasia were found in asymptomatic women below the age of 40 years. In asymptomatic women, malignancy and higher grades of dysplasia were confined to women with a clinically abnormal cervix only. Univariate analysis also revealed that subjects with a parity of more than 3 and a married life of more than 20 years had a significantly higher number of cytological abnormalities. However, on a multivariate analysis the increased number of marital years was not found to be an independent variable. These results suggest that asymptomatic women below the age of 40 years with a married life of less than 20 years and parity below 3, may be excluded from screening campaigns, and that pre-selection for cytologic screening is possible by introducing a programme of clinical and speculum examination of the cervix.     

Cervical screening in the UK and laboratory quality control in the context of the 2007 European guidelines

The first part of this article will provide an overview of cervical cancer screening in the UK during the years before, during and after the introduction of a highly successful centrally organised cervical screening programme in 1988: since then the incidence of invasive cervical cancer has fallen by more than 40%. Screening was introduced in a background of opportunistic screening with poor quality control during a period of time when risk of disease was increasing, which will be demonstrated by national registrations of carcinoma in situ as well as invasive cancer. The programme is still facing new challenges and has recently recorded falling screening coverage in younger women, the causes of which have yet to be established. Liquid-based cytology is in the process of being rolled out nationally but high-risk human papillomavirus testing has yet to be introduced into the National Health Service (NHS) programme. Lessons from our experience may be relevant to countries introducing and maintaining organised programmes elsewhere under similar circumstances. The second part of the article will consider laboratory quality control as practiced in the UK and as recommended in the second edition of the European Guidelines for Quality Assurance in Cervical Cancer Screening. These evidence-based guidelines provide recommendations for organising and monitoring quality control as well as for introducing new technology and standardising terminology, which are equally relevant for new and existing programmes. Invasive cancer audit may highlight areas where procedures could be improved in any programme but also can also demonstrate the effectiveness of screening.

Review of negative and low‐grade cervical smears in women with invasive cervical cancer after the first 3 years of the national cervical screening programme in Slovenia Objective: The purpose of the study was to perform a national review of negative, low‐grade and inadequate smears reported during the latest screening period before cervical cancer diagnosis in 2006, after the first 3 years of the screening programme. Methods: Among 162 new cervical cancer cases there were 47 (29%) without previous cytology, 47 (29%) with one high‐grade smear prior to diagnosis and 68 (42.0%) with at least one previous negative, low‐grade, atypical or inadequate smear 1–40 months before diagnosis. Of the latter 68 cases, 37 patients with 59 smears (together with 118 control slides) were included in the review as 31 had smears reported at laboratories no longer operating. Findings were related to the last cytology report before diagnosis as well as to histological type and stage of the cancer. Results: In our study group, 19 (51%) of 37 patients had squamous cell carcinoma, 15 (41%) adenocarcinoma and 3 (8%) adenosquamous carcinoma, compared with 121 (75%), 26 (16%), 12 (7%), respectively, and 3 (2%) other types, for all carcinomas. Twenty‐one of 37 women also had high‐grade cytology prior to diagnosis of cancer. Women with previous cytology (with or without recent high‐grade smears) were more likely to have stage I cancers than those without cytology (P < 0.0001). The expert group upgraded 17/33 smears in the patients with squamous carcinomas, which was more than in those with adeno‐ and adenosquamous carcinomas (5/24, P < 0.05). Conclusion: As expected, a higher proportion of smears preceding adenocarcinomas were true negative. Under‐diagnosed smears were not related to cancer stage or last cytology report before diagnosis.     

Rapid rescreening of cervical smears as a quality control method in a high-risk population

OBJECTIVE: Cancer of the cervix is one of the commonest cancers in South Africa. Accurate cytological diagnosis is one of the prerequisites for an effective cervical screening programme and requires the implementation of appropriate quality assurance modalities. This study was undertaken to determine if rapid review of reportedly negative cervical smears is a useful internal quality assurance modality in an unscreened population with very high rates of cervical carcinoma. METHOD: Approximately 26% of all cervical smears received at the study institution between 1 January 1998 and 31 December 2003, and initially reported as negative or inadequate, underwent rapid review. RESULTS: A total of 62,866 (26%) cervical smears out of 241,796 reportedly negative or inadequate cervical smears underwent rapid review. An amended report was sent out in 373 (0.59%) of these 62,866 cervical smears. This included 101 cases of high-grade squamous intraepithelial lesion (HSIL) and high-grade atypical squamous cells (ASC-H), 143 low-grade squamous intraepithelial lesions, 54 atypical squamous cells of undetermined significance (ASC-US) and 33 atypical glandular cells that were not reported initially. The false-negative proportion for HSIL and ASC-H (combined) in this study was 5.76%. No squamous cell carcinomas were diagnosed on rapid review but one patient with HSIL/ASC-H on review had squamous cell carcinoma on biopsy. Three cytotechnologists had a lower sensitivity of primary screening and required retraining. CONCLUSIONS: Rapid review is beneficial as an internal quality assurance modality in an unscreened high-risk population and increases the detection of women with significant cervical lesions requiring treatment. The relatively low cost of rapid review compared with other rescreening modalities makes this an attractive option in low resource settings.     

How complete can cervical screening be? The outcome of a call screening programme for women aged 20–60 years in Perth and Kinross

In this paper a computer system for cervical screening call and recall based on the Community Health Index (CHI) population data-base is described. It allows the unscreened population to be identified and located on an individual general practice basis. The results of the call programme on 9517 women aged 20-60 years listed on the CHI and with no record of a cervical smear is described. There was a 24% smear uptake in the call programme which meant that after the call programme the total population cover had risen from 71% to 78%. In addition, if women with a valid reason are excluded, and the data-base corrected for women no longer in the area, the true cover rises to 88%. An analysis of the percentage cover in each GP practice is described with the implications for implementation of screening targets for primary care.     

The influence of the cervix on smear quality. I: Atrophy. An audit of cervical smears taken post‐colposcopic management of intraepithelial neoplasia

Out of 951 smears taken from women attending a hospital cytology clinic, 122 were found to be of poor quality. Twenty‐eight percent of these were associated with clinical and/or cytological atrophy, and in 91% of these the main adverse factor affecting smear quality was scantiness. The relative risk of obtaining a scanty smear was found to be 4.8 times greater in women in whom clinical atrophy was identified when compared with those with no atrophy. It is suggested that a reduction in the number of scanty, and hence potentially inadequate, smears in the screening programme may be achieved by the use of more appropriate sampling implements in all women in whom there is clinical evidence of atrophy. Further review of alternative sampling methods is indicated.     

Mammography screening in the county of Fyn. November 1993-December 1999

This report covers the outcome of the first three invitation rounds of the organised mammography screening programme in the county of Fyn. The programme started in November 1993, and the third invitation round ended on 31 December 1999. The screening takes place either at a special clinic located at University Hospital Odense or in a mobile unit. Women living in and around the city of Odense are examined at the clinic (about 55%), while the rest are examined in the mobile unit. Two-view mammography is used at the first screening. Women with dense breast tissue will continue to have two-view mammography (about 60%), whereas the rest will have singleview mammography at the subsequent screens. All screening images are exposed at the mammography-screening clinic and evaluated with double reading in the clinic. The programme targets women aged 50-69, except those undergoing treatment for breast cancer or going for regular check-ups following breast cancer. Based on the updated population register, the IT-Centre of the county of Fyn issues the invitations. Invited are all women aged 50-69 and living in the county of Fyn when their general practitioners' patients are invited. During the first 3 invitation rounds, 136,079 screening tests were made. Of these, 129,375 tests were made in the women aged 50-69 targeted by the programme. In addition, 6682 screening tests were made in women aged 70 and above, and 22 screening tests were made in women below the age of 50. As a consequence of the mammography screening 2657 assessments were made, 1145 women had surgery, 782 women were diagnosed with invasive breast cancer, and 109 women were diagnosed with ductal carcinoma in situ. A participation rate for the first invitation round was calculated immediately after the end of the round based on the number of participants divided by the number of women invited. This percentage was 88%. Invitation data are, however, not stored. It is therefore not possible now to calculate the participation rates in previous invitation rounds based on the same method. We have therefore chosen to calculate the participation rate as the coverage, i.e. the number of participants divided by the average number of women in the county of Fyn during a given invitation round. Calculated in this way, 84% participated in the first round, 84% in the second round, and 82% in the third round. It should be remembered that these figures do not take into account that some women are not invited because they 1) were undergoing current treatment for breast cancer or going for regular check-ups following breast cancer, or 2) did not participate in the previous round (and never actively informed the programme that they wanted an invitation to the next invitation round), relevant only for the second and third invitation round. For the second and third invitation rounds, the programme only invited women who participated in the previous invitation round, asked the clinic for an invitation, or entered the target population since the last invitation round. Therefore the participation rate in the second invitation round among actually invited women will be close to 94%, as 94% of those participating in the first round came for the second round. For the third invitation round, the participation rate among actually invited women will be close to 96%, as 96% of those participating in the first and second rounds came for the third round. One per cent of the participants in the first invitation round were diagnosed with invasive breast cancer or ductal carcinoma in situ. The detection rate was 0.5% in both the second and third invitation rounds. Ductal carcinoma in situ cases constituted 14% of the detected cases in the first and second rounds, and 10% in the third round. The percentage of invasive breast cancer 10 mm of less was 38%, 31%, and 32%, respectively, and 68%, 74%, and 73%, respectively, were node-negative. The screening programme of the county of Fyn fulfilled all the quality assessment parameters specified by the European guidelines on breast cancer screening, except two. The proportionate interval cancer rate was higher than specified in the guidelines, probably mainly due to the fact that the Fyn programme operates without early recalls. The proportion of stage II+ cancers was higher than specified in the guidelines, which seems, however, to be due to inconsistency between some of the performance indicators in the European guidelines. This analysis of the outcome from the first three invitation rounds of the mammography screening programme in the county of Fyn thus showed that it is a programme of high quality with a favourable profile of the prognostic indicators. The screening programme is hopefully well on its way to reducing breast cancer mortality in the county of Fyn.     

Cervical cancer screening in the Czech Republic

Cytological diagnosis of atypical cells of cervix uteri by the Papanicolaou method was introduced in the Czech Republic (CR) very early - in 1947. The first data on the incidence of cervical cancer in CR are available from 1960 when the rate was 32.3 cases/10(5) women. In 1966 the Czech National Health Law was passed that guaranteed women a yearly preventive examination by a gynaecologist including screening for cervical carcinoma that would be covered by the compulsory health insurance. Notwithstanding high frequency of screening visits and the fact that all women are eligible, the incidence of CC has not changed in the last 34 years. The reasons for this include the coverage of Czech women, which is estimated to be low (50% at the most), and that none of the cytology laboratories are accredited for screening, there are no national registries for any aspect of screening and there are no mechanisms for evaluation of the screening process. As a result, it is likely that the majority of cervical screening activity that is undertaken is ineffective and the implementation of an organised and quality controlled screening programme, in compliance with the recommendations of many European Institutions, is urgently required to ensure that Czech women are properly protected against this disease and that scarce healthcare resources are used in the most cost-effective manner.     

Cervical cancer screening in Mediterranean countries: implications for the future

K. Syrjänen, L. Di Bonito, L. Gonçalves, L. Murjal, M. Santamaria, V. Mahovlic, P. Karakitsos, B. Önal and F. C. Schmitt Cervical cancer screening in Mediterranean countries: implications for the future Prompted by feedback from the 34th European Congress of Cytology (ECC), the practice of including a special symposium in the programme was continued in the 35th ECC in Lisbon (2009) by arranging a satellite symposium entitled ‘Cervical Cancer Screening in the Mediterranean Countries’. Because of the importance to the future of this discipline, it was felt appropriate to summarize the highlights of this symposium here. Cervical cancer prevention strategies in the countries participating in the symposium (Portugal, Spain, Italy, Croatia, Greece and Turkey) appear to be highly variable. As yet, none of these countries can demonstrate a fully implemented national screening programme, but all are in different phases of designing and/or setting up such a programme, which is important. At present, the time‐honoured concept of cervical cancer prevention by Pap smear screening is under review, because prophylactic human papillomavirus (HPV) vaccines demonstrate a potential to prevent the vast majority (albeit not all) of cases of cervical cancer in the foreseeable future. Cervical cancer screening is still needed in this emerging era of HPV vaccination, but clearly the existing screening strategies must be modified to provide a cost‐effective combination of vaccination and screening. If the currently evaluated new screening strategies, such as HPV testing followed by cytology triage, become a reality, there is the likelihood that the Pap test will have only a secondary role, subordinate to HPV testing. Supporters of this scenario claim that Pap test performance will deteriorate in vaccinated populations. Reduced positive predictive value (PPV), due to lower disease prevalence, is inevitable, however, and this would also affect HPV tests. Any decline in sensitivity and specificity depends on human performance, and as such is avoidable by taking appropriate preventive measures. As clinical cytologists, we should focus attention on minimizing the risk to the Pap test of falling sensitivity because of unfamiliarity with abnormal cells, and also of reduced specificity if the fear of missing significant disease leads to overcalling of benign abnormalities.     

Effective serological and molecular screening of deceased tissue donors

A comprehensive and effective screening programme is essential to support the banking of tissues from deceased donors. However, the overall quality of the samples obtained from deceased donors, quantity and condition, is often not ideal, and this may lead to problems in achieving accurate and reliable results. Additionally a significant percentage of referrals are still rejected upon receipt as unsuitable for screening. We are actively involved in improving the overall quality of deceased donor screening outcomes, and have specifically evaluated and validated both serological and molecular assays for this purpose, as well as developing a specific screening strategy to minimise the specificity issues associated with serological screening. Here we review the nature and effectiveness of the deceased donor screening programme implemented by National Health Service Blood and Transplant (NHSBT), the organisation with overall responsibility for the supply of tissue products within England. Deceased donor screening data, serological and molecular, from August 2007 until May 2012 have been collated and analysed. Of 10,225 samples referred for serology screening, 5.5 % were reported as reactive; of 2,862 samples referred for molecular screening, 0.1 % were reported as reactive/inhibitory. Overall 20 % of the serological and 100 % of the molecular screen reactivity was confirmed as reflecting true infection. The use of a sequential serology screening algorithm has resulted in a marked reduction of tissues lost unnecessarily due to non-specific screen reactivity. The approach taken by NHSBT has resulted in the development of an effective and specific approach to the screening of deceased tissue donors.     

Effectiveness of the public health policy for breast cancer screening in Finland: population based cohort study.

OBJECTIVE: To evaluate the effectiveness of screening for breast cancer as a public health policy. DESIGN: Follow up in 1987-92 of Finnish women invited to join the screening programme in 1987-9 and of the control women (balanced by age and matched by municipality of residence), who were not invited to the service screening. SETTING: Finland. SUBJECTS: Of the Finnish women born in 1927-39, 89893 women invited for screening and 68862 controls were followed; 1584 breast cancers were diagnosed. MAIN OUTCOME MEASURES: Rate ratio of deaths from breast cancer among the women invited for screening to deaths among those not invited. RESULTS: There were 385 deaths from breast cancer, of which 127 were among the 1584 incident cases in 1987-92. The rate ratio of death was 0.76 (95% confidence interval 0.53 to 1.09). The effect was larger and significant (0.56; 0.33 to 0.95) among women aged under 56 years at entry. 20 cancers were prevented (one death prevented per 10000 screens). CONCLUSIONS: A breast screening programme can achieve a similar effect on mortality as achieved by the trials for breast cancer screening. However, it may be difficult to justify a screening programme as a public health policy on the basis of the mortality reduction only. Whether to run a screening programme as a public health policy also depends on its effects on the quality of life of the target population and what the resources would be used for if screening was not done. Given all the different dimensions in the effect, mammography based breast screening is probably justifiable as a public health policy.     

ABC3 Part II: a review of the new criteria for evaluating cervical cytology in England

R.G. Blanks
ABC3 Part II: a review of the new criteria for evaluating cervical cytology in England The new Achievable Standards, Benchmarks for Reporting, and Criteria for Evaluating Cervical Cytopathology, 3rd edn (ABC3) includes radical changes in the criteria for evaluating cervical cytology. First, they include a new mission statement ‘the objective of cervical screening is to reduce cervical cancer incidence and mortality by screening with a high sensitivity for the detection of CIN2 or worse, whilst maintaining a high specificity’. Second, the original four performance measurement criteria where laboratories were examined further if they were below the 10th or above the 90th percentile has been changed to three and laboratories are only mandatorily examined if they fall below the 5th or above the 95th percentile. The old criteria related to the percentage of samples that were inadequate, the percentage of all adequate samples reported as moderate dyskaryosis or worse (equivalent to high‐grade squamous intraepithelial lesion or cancer), the percentage of adequate samples reported as mild dyskaryosis or borderline (equivalent to low‐grade squamous intraepithelial lesion or atypical squamous/glandular cells) and the positive predictive value. The new criteria are percentage of inadequate samples, positive predictive value and a new measure termed referral value. These changes mean that far fewer laboratories will require mandatory examination. Third, a raft of optional performance measures have been introduced to help laboratories examine their annual statistical return to the Department of Health in comparison with other laboratories. These measures have been designed to produce a more uniform national programme, and to help laboratories decide whether they are maximizing the benefit of screening while minimizing the harm, which is the goal of all screening programmes. This review examines in detail the new criteria and explains in more detail some of the thinking behind them.     

Costs and benefits of cervical screening. III. Cost/benefit analysis of a call of previously unscreened women

A population‐based cervical screening programme issued invitations to women with no record of a previous smear. This call was very good value, at £5780 per life saved or £159 per life‐year saved at 1991 prices. The first priority for the cervical screening service should be comprehensive coverage.     

The long-term impact of the Leprosy Post-Exposure Prophylaxis (LPEP) program on leprosy incidence: A modelling study

BackgroundThe Leprosy Post-Exposure Prophylaxis (LPEP) program explored the feasibility and impact of contact tracing and the provision of single dose rifampicin (SDR) to eligible contacts of newly diagnosed leprosy patients in Brazil, India, Indonesia, Myanmar, Nepal, Sri Lanka and Tanzania. As the impact of the programme is difficult to establish in the short term, we apply mathematical modelling to predict its long-term impact on the leprosy incidence.MethodologyThe individual-based model SIMCOLEP was calibrated and validated to the historic leprosy incidence data in the study areas. For each area, we assessed two scenarios: 1) continuation of existing routine activities as in 2014; and 2) routine activities combined with LPEP starting in 2015. The number of contacts per index patient screened varied from 1 to 36 between areas. Projections were made until 2040.Principal findingsIn all areas, the LPEP program increased the number of detected cases in the first year(s) of the programme as compared to the routine programme, followed by a faster reduction afterwards with increasing benefit over time. LPEP could accelerate the reduction of the leprosy incidence by up to six years as compared to the routine programme. The impact of LPEP varied by area due to differences in the number of contacts per index patient included and differences in leprosy epidemiology and routine control programme.ConclusionsThe LPEP program contributes significantly to the reduction of the leprosy incidence and could potentially accelerate the interruption of transmission. It would be advisable to include contact tracing/screening and SDR in routine leprosy programmes.     

European trends in cervical cancer mortality in relation to national screening programs, 1985–2014

BackgroundCervical cancer is the fourth leading oncological cause of death in women. Variable trends in cervical cancer mortality have been observed across Europe, despite the widespread adoption of screening programs. This variability has previously been attributed to heterogeneity in the quality of screening programs.MethodsAge-standardized cervical cancer death rates for European countries between 1985 and 2014 were analyzed using Joinpoint regression. Countries were dichotomized based on year of implementation and population invitational coverage of national population-based cervical cancer screening programs. National cervical cancer mortality trends during the study period were compared based on this classification.ResultsDecreasing trends in mortality were observed in all European countries with the specific exceptions of Bulgaria, Greece and Latvia. The highest rates of cervical cancer mortality throughout the study period were in Romania (16.0-14.9/100,000) and the lowest rates in Italy (1.4-1.2/100,000). The greatest percentage decline in mortality was observed in the United Kingdom and the greatest absolute reduction in mortality was seen in Hungary. European countries which implemented a national population-based cervical cancer screening program prior to 2009 demonstrated greater improvements in cervical cancer mortality outcomes compared to those that did not (p = 0.016).ConclusionCervical cancer mortality is improving in most European countries; however, substantial variation remains. Trends in mortality were associated with the time of implementation of national population-based cervical screening programs.     

ABC3 Part I: a review of the guidelines for terminology,classification and management of cervical cytology in England

J. H. F. Smith ABC3 Part I: a review of the guidelines for terminology, classification and management of cervical cytology in England The provision of guidance on cytology reporting and evaluation, first outlined in 1995 with the publication of Achievable Standards, Benchmarks for Reporting, and Criteria for Evaluating Cervical Cytopathology (ABC), and subsequently revised and expanded in a second edition in 2000, has been pivotal to the success of the National Health Service Cervical Screening Programme (NHSCSP), ensuring that standards are upheld, and that rigorous evaluation and quality assurance take place. In the last decade, major changes to the NHSCSP, notably the adoption of revised age ranges and screening intervals for all women in England, implementation of liquid‐based cytology and, most recently, the decision to introduce high‐risk human papillomavirus (HR‐HPV) testing for triage of low‐grade and borderline (equivalent to 'atypical') cytological abnormalities and test of cure after treatment of cervical intraepithelial neoplasia (CIN) determined that an updated version of ABC was required. The third edition of ABC recommends adoption, with minor modification, of the revised British Society for Clinical Cytology terminology and provides guidance on the management of abnormal cytology results linked to this terminology taking account of HR‐HPV testing. To accommodate these changes, expanded result codes, which are electronic codes used to transfer management information to central computers for follow‐up, call and recall of individual women, have been developed. Further guidance on specimen adequacy is also provided. Revised performance indicators are described and explained in a separate article by R. Blanks in this issue of Cytopathology. All the changes in ABC3 are designed to support the mission statement of the NHSCSP that ‘the objective of cervical screening is to reduce cervical cancer incidence and mortality by screening with a high sensitivity for the detection of CIN2 or worse, whilst maintaining a high specificity’.     

Clinical relevance of human papillomavirus testing in cytopathology

Cancer of the uterine cervix is the second most common cancer in women worldwide. Currently, cervical screening is based on cytology alone. Because infection with high-risk human papillomavirus types (hrHPVs) is a necessary cause of cervical cancer, it has been postulated that screening might become more efficient when it is based on combined cytology and hrHPV testing. In this review we will discuss the advantages of added HPV tests in cervical cancer screening, as a quality control for false-negative smears, in triage of women with equivocal smears, in follow-up of women treated for CIN3 or cervical cancer and for the detection of cervical adenocarcinoma.     

Primary HPV testing: a proposal for co‐testing in initial rounds of screening to optimise sensitivity of cervical cancer screening

As explained by Kitchener in a previous issue of Cytopathology (2015; 26 :4‐6), primary human papillomavirus (HPV) testing is likely to be introduced in the UK for all women aged 25–64 years following pilot site studies already in place. This will be necessary when the prevalence of cervical cancer and its precursors declines when vaccination takes effect but there is a risk in abandoning cytology as a primary test: a risk that would be most apparent in the present unvaccinated population in which the prevalence of cervical cancer and its precursors is exceptionally high. HPV testing is more sensitive than cytology but has a significant false‐negative rate that could be detrimental to a successful screening programme if introduced without cytology backup. Accurate cytology would be needed for triage and could be compromised if HPV‐negative tests were excluded from examination. This article proposes a compromise: cytology and HPV co‐testing for the first two screening tests to optimise the sensitivity of the test as a whole. Registrations of invasive and in situ carcinoma of the uterine cervix in England indicate that the prevalence of the disease is highest in young women in the early rounds of screening. Calculations of the likely impact on the workload of this proposal have been based on a service evaluation of 295 cytology tests received at St Thomas’ Hospital, which suggests that the volume of cytology tests would be reduced by approximately 60% compared with 80% for primary HPV testing alone. This proposal should be debated openly before irrevocable changes are made to a skilled workforce.     

Implementing an organised cervical screening programme in the Republic of Moldova—Stakeholder identification and engagement

IntroductionSuccessfully implementing cervical screening programmes requires them to be adapted to the local context and have broad stakeholder support. This can be achieved by actively engaging local stakeholders in planning as well as implementing the programmes. The Moldovan government started implementing an organised cervical screening programme in 2010 with the first step being stakeholder identification and engagement.Materials and methodsThis process started by contacting easily identified stakeholders with each asked to recommend others and the process continued until no new ones were identified. Stakeholders were then involved in a series of individual and group meetings over a 2-year period to build confidence and encourage progressively greater engagement.ResultsIn total, 87 individuals from 46 organisations were identified. Over the 2-year process, the individual and group meetings facilitated a change in stakeholder attitudes from disinterest, to acceptance and finally to active cooperation in designing the screening programme and preparing an implementation plan that were both well adapted to the Moldovan context.DiscussionDeveloping the broad support needed to implement cervical screening programmes required ongoing interaction with stakeholders over an extended period. This interaction allowed stakeholder concerns to be identified and addressed, progress to be demonstrated, and stakeholders to be educated about organised screening programmes so they had the knowledge to progressively take greater responsibility and ownership.     

Organisation and results of the cervical cytology screening programme in British Columbia, 1955-85

A screening programme to detect preinvasive carcinoma of the cervix was started in British Columbia in 1949. Since 1970 the number of women who have been screened at least once has been maintained at about 85% of the population at risk. More than 500 000 cervical smears are being examined each year in the central laboratory. There has been an appreciable increase in the number of cases and rates of carcinoma in situ seen since 1970, particularly in women between 20 and 30 years of age. Since the programme started over 26 000 cases of squamous carcinoma in situ have been detected and treated. The incidence of clinically invasive squamous carcinoma of the cervix has fallen by 78% during the period under review, and mortality from squamous carcinoma of the cervix has fallen by 72%. A colposcopy programme, introduced throughout British Columbia over the past 12 years, has been important in reducing the problems of managing preinvasive lesions, particularly in younger women.It is concluded that the reduction in morbidity and mortality from invasive squamous cancer of the cervix in British Columbia over the past 30 years is directly attributable to the province wide screening programme and that a large potential increase in invasive cervical cancer rates among younger women is being prevented.
