Objective –To present results from the NHS breast screening programme (NHSBSP) for the three year period 1990 to 1993, and to examine the extent to which interim targets are being met. Methods –Data have been collated from all screening programmes in the United Kingdom on standard “Korner” returns, supplemented for the year 1991/92 by data from the radiology quality assurance programme. Most of the data refer to the prevalent screening round, but some data on rescreening are also available. Results –The total cancer detection rate at prevalent screens was 6·0/1000, 18% being in situ cancers; the detection rate of invasive cancers ⩽ 10 mm in diameter was 1·3/1000, but data on size were missing for 12% of cancers. Referral rates were significantly lower for programmes using' two view mammography at the prevalent screen than for those using single view, and cancer detection rates were significantly higher. For prevalent screens over the three year period, 70% of programmes had a referral rate of ≤ 7%, 87% had a benign biopsy rate of ≤ 5/1000, and 79% had a cancer detection rate of ≥ 5/1000. By contrast, only 30% of programmes appeared to meet the target detection rate of > ⩽5/1000 for invasive cancers ≤ 10 mm in diameter. Conclusions – While the majority of interim targets are being met by the NHSBSP, the rate of detection of small invasive cancers requires careful monitoring. Collection of more accurate data on size of cancers and interval cancer rates will give a better indication of progress towards the target mortality reduction.

Objective Monitoring breast screening programmes is essential to ensure quality. BreastCheck, the national breast screening programme in the Republic of Ireland, commenced screening in 2000, with full national expansion in 2007, and digital mammography introduced in 2008. We aimed to review the performance of BreastCheck from 1 January 2004 to 31 December 2013. Methods Using the customised clinical and administrative database, performance indicator data were collected from BreastCheck and compared with programme and European guideline standards. Results Over the decade, 972,236 screening examinations were performed. Uptake initially rose following national expansion, but fell in the subsequent years to <70% in 2012–2013. Following the introduction of digital mammography, initial recall rates increased from 5.2% in 2004–2005 to 8.1% in 2012–2013. Subsequent recall rates remained within the target of <3%. On average, invasive cancer detection rates were 6.6/1000 for initial and 4.5/1000 for subsequent women. Small cancer detection rates were for <15 mm 43.4% (initial women) and 51.7% (subsequent) and for ≤10 mm 24.0% (initial) and 29.5% (subsequent). Ductal carcinoma in situ detection as a percentage of all cancers averaged 21.2% for initial and 20.0% for subsequent women. The majority were intermediate or high-grade ductal carcinoma in situ. The positive predictive value was 11.9% for initial and 21.8% for subsequent women. Standardized detection ratios remained above the programme target. Conclusion Revised indicators to reflect the digital mammography era are anticipated in revised European Guidelines on breast cancer screening.

Objective— To examine the effect of using two view mammography in comparison with one view mammography in the detection of small (<15 mm) invasive cancers. Setting— Screening programme data from National Health Service breast screening programme (NHSBSP). Methods— Data were collated from all screening programmes in the United Kingdom on standard “Korner” returns (KC62 forms) for the screening year 1 April 1994 to 31 March 1995. The comparison of invasive cancer detection rates by programmes using one and two view mammography with indirectly age standardised invasive cancer detection rates. Results— Programmes using two views for women attending their prevalent screen (first screen) in the NHSBSP detected 3% more non-invasive/microinvasive cancers, 7% more large invasive cancers (⩽15 mm), and 42% more small invasive cancers (<15 mm) than programmes using one view mammography. Conclusions— The success of the screening programme depends largely on the ability of individual programmes to detect small invasive cancers. The results suggest that the benefit of using two view mammography is largely in the increased detection of these cancers.

Objective To use results on recall rates from a regional non-population-based breast screening programme to inform practice in a planned national population-based programme. Methods We analysed data on rates of recall for further assessment in 27,327 mammographic screening episodes in 2015–2016 in the breast screening programme in the city of Tbilisi, Georgia. Screening was done by two-view digital mammography with double reading in women aged 40–70, and further assessment took place at the same clinic and during the same visit as the initial screening mammogram. Results The recall rates were 46% (3573/7824) in 2015 and 27% (5276/19,503) in 2016. Cancer detection rates were 8 per 1000 in 2015 and 3 per 1000 in 2016. Rates of recall were higher in younger women than in older, whereas the rates of cancer detection were higher in older women. Conclusions The recall rates, while lower in 2016 than in 2015, are still too high to manage in a nationwide population programme. The use of same-visit assessment is likely to be contributing to this. The national programme should consider separate assessment clinics and carry out audit of recalls to date.
