Impact analysis: Extending BreastScreen Aotearoa to include women aged 70-74 years

May, 2019
This analysis provides a summary of the potential impacts of extending the age range for the national breast screening programme, BreastScreen Aotearoa, to include women up to age 74. The analysis uses modelling and what we know about breast cancer and breast screening to provide a high-level summary of the impacts of a potential age extension on women, screening and treatment providers and the wider health sector. One of its aims is to help shape changes to the existing programme to provide the most benefit for New Zealanders.

Interval Cancers in the Bowel Screening Pilot – Preliminary Report FIT negative

March, 2019
The report provides a preliminary analysis of interval cancers from the Bowel Screening Pilot (BSP) and early estimates of sensitivity. Interval cancers are cancers that are diagnosed between a negative (normal) screen and the time the next screen would have occurred. Sensitivity is the proportion of cancers in the screened population that are identified through screening. This report is preliminary as it is restricted to the first four years of the BSP and solely refers to interval cancers and sensitivity relating to the faecal immunochemical test (FIT) part of the screening pathway. It is also preliminary as it does not include interval cancers diagnosed following a negative diagnostic test (colonoscopy or computed tomographic (CT)-colonoscopy) undertaken in response to a positive FIT. Neither does the report include the stage or sight of the interval cancers. The report has been produced to share the information gathered to date in the spirit of transparency and open communication. However, caution is advised in drawing any strong conclusions from analysis due in part to the restrictions noted above but more importantly because the number of cancers identified to date is small.

Interval cancers in BreastScreen Aotearoa 2008-2009

February, 2018
This report presents analysis of interval cancers from the BreastScreen Aotearoa (BSA) programme. Interval cancers are those diagnosed between a normal screening result and the next scheduled screen (in BSA this interval is two years). The report covers 2008–2009 screens and makes comparisons to previously published BSA data and international results.

Cohort and Case Control Analyses of Breast Cancer Mortality: BreastScreen Aotearoa 1999-2011

December, 2015
This major new study confirms that New Zealand’s organised breast screening programme, BreastScreen Aotearoa (BSA) is reducing deaths from breast cancer. The study concludes that for women who have ever been screened by BSA, the rate of death from breast cancer is reduced by a third, compared to women never screened by the programme. The findings of this study are in line with mortality studies of breast screening programmes internationally.
