Objective –To investigate changes in attendance over the course of a population based breast screening programme. Design – Longitudinal; analysis of registered data over nine screening rounds. Setting –Subjects belong to the screening population of the Nijmegen experimental breast screening programme (1975–1990). Subjects –A cohort of 6898 women who were enrolled in 1975 at the age of 50–69 years and who were invited to nine subsequent screening rounds, irrespective of their attendance at previous rounds. Results –Attendance of women aged 50–53 years at entry was high at the initial screening (88%), decreased in the course of the programme, but remained well over 60% until round 8; 39% completed nine rounds and 24% completed seven to eight rounds. Attendance of women who were older at entry was somewhat lower at the initial screening (87%–82%) and declined more strongly. Regular compliance was also lower. Specific compliance patterns are found that can be relevant for further research. Conclusions –A substantial proportion of eligible women can be committed to mammography every two years, possibly even after reaching the age of 70, if the age at entry is around 50 and the screening programme is well established in the community. Starting a screening programme in older women seems ineffective.

Objective The Norwegian Breast Cancer Screening Programme invites women aged 50–69 to biennial mammographic screening. Although 84% of invited women have attended at least once, attendance rates vary across the country. We investigated attendance rates among various immigrant groups compared with non-immigrants in the programme. Methods There were 4,053,691 invitations sent to 885,979 women between 1996 and 2015. Using individual level population-based data from the Cancer Registry and Statistics Norway, we examined percent attendance and calculated incidence rate ratios, comparing immigrants with non-immigrants, using Poisson regression, following women's first invitation to the programme and for ever having attended. Results Immigrant women had lower attendance rates than the rest of the population, both following the first invitation (53.1% versus 76.1%) and for ever having attended (66.9% versus 86.4%). Differences in attendance rates between non-immigrant and immigrant women were less pronounced, but still present, when adjusted for sociodemographic factors. We also identified differences in attendance between immigrant groups. Attendance increased with duration of residency in Norway. A subgroup analysis of migrants' daughters showed that 70.0% attended following the first invitation, while 82.3% had ever attended. Conclusions Immigrant women had lower breast cancer screening attendance rates. The rationale for immigrant women's non-attendance needs to be explored through further studies targeting women from various birth countries and regions.

Objectives: To illustrate the ability of the West Midlands breast screening status algorithm to assign a screening status to women with malignant breast cancer, and its uses as a quality assurance and audit tool. Methods: Breast cancers diagnosed between the introduction of the National Health Service [NHS] Breast Screening Programme and 31 March 2001 were obtained from the West Midlands Cancer Intelligence Unit (WMCIU). Screen-detected tumours were identified via breast screening units, and the remaining cancers were assigned to one of eight screening status categories. Multiple primaries and recurrences were excluded. Results: A screening status was assigned to 14,680 women (96% of the cohort examined), 110 cancers were not registered at the WMCIU and the cohort included 120 screen-detected recurrences. Conclusions: The West Midlands breast screening status algorithm is a robust simple tool which can be used to derive data to evaluate the efficacy and impact of the NHS Breast Screening Programme.

AbstractObjectiveTo evaluate the long term risks of invasive breast cancer and death from breast cancer after ductal carcinoma in situ (DCIS) diagnosed through breast screening.DesignPopulation based observational cohort study.SettingData from the NHS Breast Screening Programme and the National Cancer Registration and Analysis Service.ParticipantsAll 35 024 women in England diagnosed as having DCIS by the NHS Breast Screening Programme from its start in 1988 until March 2014.Main outcome measuresIncident invasive breast cancer and death from breast cancer.ResultsBy December 2014, 13 606 women had been followed for up to five years, 10 998 for five to nine years, 6861 for 10-14 years, 2620 for 15-19 years, and 939 for at least 20 years. Among these women, 2076 developed invasive breast cancer, corresponding to an incidence rate of 8.82 (95% confidence interval 8.45 to 9.21) per 1000 women per year and more than double that expected from national cancer incidence rates (ratio of observed rate to expected rate 2.52, 95% confidence interval 2.41 to 2.63). The increase started in the second year after diagnosis of DCIS and continued until the end of follow-up. In the same group of women, 310 died from breast cancer, corresponding to a death rate of 1.26 (1.13 to 1.41) per 1000 women per year and 70% higher than that expected from national breast cancer mortality rates (observed:expected ratio 1.70, 1.52 to 1.90). During the first five years after diagnosis of DCIS, the breast cancer death rate was similar to that expected from national mortality rates (observed:expected ratio 0.87, 0.69 to 1.10), but it then increased, with values of 1.98 (1.65 to 2.37), 2.99 (2.41 to 3.70), and 2.77 (2.01 to 3.80) in years five to nine, 10-14, and 15 or more after DCIS diagnosis. Among 29 044 women with unilateral DCIS undergoing surgery, those who had more intensive treatment (mastectomy, radiotherapy for women who had breast conserving surgery, and endocrine treatment in oestrogen receptor positive disease) and those with larger final surgical margins had lower rates of invasive breast cancer.ConclusionsTo date, women with DCIS detected by screening have, on average, experienced higher long term risks of invasive breast cancer and death from breast cancer than women in the general population during a period of at least two decades after their diagnosis. More intensive treatment and larger final surgical margins were associated with lower risks of invasive breast cancer.

Strong Increase

As populations of developed countries are aging, the number of older women with breast cancer will strongly increase. Randomized controlled trials in breast cancer screening rarely included patients over the age of 68. As a consequence, there is no solid evidence for beneficial effects of breast cancer screening in older women. In a recent observational study, we showed that the implementation of screening in women aged 70–75 in the Netherlands resulted in a strong increase of the incidence of early-stage breast cancer, while the incidence of advanced stage breast cancer barely decreased. Hence, current data do not support population-based screening in women over the age of 70.
