“…This is in line with findings from other countries where, for instance, the participation rate was lower in Stockholm [15] than in rural Sweden [16][17][18][19][20], lower in Torino than in Brescia [21], lower in Valencia than in Navarra [22,23], and similar patterns were seen in the Netherlands and the UK [24]. It is noteworthy that in fact the highest coverage in Europe of 89% was found in Norrbotten, Sweden [25], which is the area in Europe with the lowest population density.…”

Women’s Patterns of Participation in Mammography Screening in Denmark

The objective of the study is to analyse individual women's participation patterns in mammography screening in Denmark. The study is set in the capital of Copenhagen and the county of Fyn representing around 95,000 women aged 50-69. The Central Population Register (CPR) was used to define the total target group, and supply information on migrations and deaths. Invitation and participation data came from the mammography screening programmes in Copenhagen (1991-1999) and Fyn (1993-2001), containing personal identification number, data on invitation date, participation and examination date for each screening round. In Copenhagen the coverage went from 70.5% in the first round to 63.1% in the fourth round, and the equivalent data for Fyn is 84.6% in the first round and 82.8% in the fourth round. Of the women eligible for at least three invitation rounds, 52.6% in Copenhagen and 76.4% in Fyn were faithful users, i.e. had participated in all screenings they were invited to. The conclusion is that the programme participation rates tend to overestimate the protection of the individual women covered by the programme. Behind the urban-rural gradient in programme participation is an even greater gradient in programme protection.

“…Rates of false-positive mammographic screening vary widely, but tend to be lower in organised breast screening programmes. To our knowledge, the only data on false-positive results for mammographic screening in women under age 50 in Europe are from Navarra, Spain, reporting prevalent screen false-positive rates of 23%, however, initial screening was by single view mammography and recall was frequently limited to the requirement for a second view (12). …”

Background False-positive recall is a recognised disadvantage of mammographic breast screening and the rate of such recalls may be higher in younger women, potentially limiting the value of screening below age 50. Methods Attendance and screening outcome data for 53 884 women in the intervention arm of the UK Age trial were analysed to report observed false-positive recall rates during 13 years of trial fieldwork. The Age trial was a randomised controlled trial of the effect of mammographic screening from age 40 on breast cancer mortality, conducted in 23 NHS Screening centres between 1991 and 2004. Women randomised to the intervention arm were offered annual invitation to mammography from age 40/41 to age 48. Results Overall, 7893 women (14.6% of women the intervention arm and 18.1% of women attending at least one routine screen) experienced one or more false-positive screen during the trial. The rates of false-positive mammography at first and subsequent routine screens were 4.9% and 3.2%, respectively. The cumulative false-positive rate over seven screens was 20.5%. Eighty-nine percent of women who had a false-positive recall at their previous screen attended their next invitation to routine screening. Conclusions Rates of false-positive recall in the Age trial were comparable with the national screening programme, however, the positive predictive value of referral was lower. Experiencing a false-positive screen did not appear to lessen the likelihood of re-attendance in the trial. Impact The question of greatly increased false-positive rates in this age group and of their compromising re-attendance is refuted by the findings of this study.

“…source in all registers is the regional morphology registers (Renaud et al, 1994;McCann et al, 1997;Bray et al, 2002). Estimation of completeness for BC has in several of the registers been reported up to 98% (Mattsson and Wallgren, 1984;Ascunce et al, 1994;Barlow et al, 2009). All three Nordic regions included in this study have access to very accurate data on population (allowing individual invitation), screening, cancer and causes of death.…”

The objective of this study was to assess detection rates and interval breast cancer (IC) rates from eight programmes in the European Breast Cancer Screening Network. A common data collection protocol was used to explore differences in IC rates among programmes and discuss their potential determinants. Pooled analysis was used to describe IC rates by age, compliance in screening, recall rate, screening detection (SD) rate and expected breast cancer incidence. Participation in screening averaged 77.9% (range 42.6-88.7%), recall rate 5.4% (range 3.3-17.7%) in the initial and 3.4% (range 1.8-8.9%) in the subsequent screening rounds, and SD rate was 60.4 (range 41.6-91) per 10 000 women in initial and 38.5 (range 31.3-62.6) in subsequent screens. IC rate during first 12 months after screening was 5.9 (range 2.1-7.3) per 10 000 women screened negative and 12.6 (range 6.3-15) in the second year of the interval. IC comprised 28% of the IC and SD cancers. The ratio between IC rate and expected incidence was 0.29 for the first 12 months and 0.63 for the 13-24 months period. Sensitivity was higher for the ages 60-69 years and for initial tests than subsequent tests. There were distinct differences in the IC rates between programmes. The results of this study reveal large variations in screening sensitivity and performance. Pooled evaluation of some process indicators within the European breast cancer screening programmes proved to be feasible and is likely to be useful for the future, particularly if it is performed regularly and extensively.
