High quality breast imaging and accurate image assessment are critical to the early diagnoses, treatment and management of women with cancer. Mammography is the primary diagnostic tool for detecting breast cancer with 800,000 women X-rayed annually in Australia however, it fails to detect 30% of breast cancers, with many missed cancers being visible on the image. The Breast Screen Reader Assessment Strategy (BREAST) monitors mistakes, identify reasons for mammographic errors and create innovative solutions to reduce errors.

BREAST is based on digital screen reading test sets designed to assess the performance of radiologists and radiology registrars. Developed by a team of researchers at the University of Sydney in collaboration with Cancer Institute NSW in 2011, BREAST has made it possible for thousands of clinicians to assess their performance on high-quality test sets in mammography and digital breast tomosynthesis, at workshops and in their own clinics. This immediate feedback is made possible through the online app, BreastScore. To view how BreastScore works, check out our video.

The data generated by BREAST are de-identified and used for further research in the fields of radiology performance, perception science, medical imaging technologies, breast imaging optimisation, and other domains.

These features make BREAST a powerful radiology training and research tool that is being used in Australia, New Zealand, Asia, Middle East, and Europe.

BREAST in Hanoi

In collaboration with Bach Mai hospital and GE Healthcare and with the funding from the Sydney SouthEast Asia Centre under the Research Cluster scheme, Prof. Patrick C Brennan, Dr. Phuong Dung (Yun) Trieu and St-Matt students from the Outreach program run the BREAST study in Hanoi in November 2019 to explore the improvement of Vietnamese radiologists in reading mammograms via BREAST test sets. There were 35 radiologists participating in the event with each radiologist reading two BREAST test sets (60 cases in each set) and explored their enhancement in cancer detection on mammograms. This study is conducted following the success of two BREAST workshops organized in Hanoi (2016) and Ho Chi Minh city (2018) funded by SSEAC Workshop Grant.

First BREAST workshop in China

In collaboration with Hologic China, and with funding from the China Studies Centre, the BREAST team offered test sets to Chinese radiologists for the first time during the National Breast Imaging Annual Conference of the Committee of Breast Imaging under the Society of Radiology. The workshops were held in the city of Nanchang, Jiangxi Province. It was attended by 57 radiologists from all over China, who completed either a mammography test set, or a digital breast tomosynthesis (DBT) test set. The conference itself was attended by hundreds of delegates, and Professor Patrick Brennan and Dr Gayathi Jiang from BreastScreen NSW gave key note talks.

High School STEM program

Since 2016, the BREAST team has helped students from a rural NSW high school explore research questions around how radiologists detect breast cancers on mammograms. Using data from the BREAST databank and involving radiologists from all over the world, Year 9 to 11 students from St. Matthew’s High School in Mudgee are working to help our understanding of performance variations in different countries where screening programs may or may not be in place. The students will be travelling with the BREAST team to Vietnam this year to help collect new data. Read more about it here.

Grant success

October 2019: Out of 115 applications for outstanding initiatives and potential positive economic and social impacts, our application entitled “VIETRAD: Transforming breast cancer diagnoses across Vietnam” had been selected for the Aus4Innovation Partnership Grant Award. This grant is funded by the Australian Department for Foreign Affairs and Trade (DFAT) and the InnovationXchange (IXC) to help strengthen the Vietnamese innovation system. Our project will partner with the Vietnamese Health Strategy and Policy Institute to develop VIETRAD, an innovation BREAST-type program, tailored for Vietnamese radiologists to improve the skills of local readers in detecting breast cancer. Our team, Prof. Patrick Brennan and Dr. Phuong Trieu (Yun) along with Dr. Tran Thi Mai Oanh (Director of Health Strategy and Policy Institute – Vietnamese Ministry of Health) will kick-off this project in Hanoi, Ho Chi Minh City and Hue-Da Nang in 2020.

Dr. Khuong A Tuan (Deputy Director of Vietnam Health Strategy and Policy Institute) received the award at the Aus4Innovation ceremony in Hanoi on 9 October 2019 on behalf of the team.

October 2019: Our application entitled “Understanding the diagnostic efficacy of radiologists in Shanghai, China using mammographic and tomographic test set images” has been selected for funding in the University of Sydney – Fudan University Partnership collaboration Award (PCA) 2019 round. Our collaboration will introduce the innovative and interactive online platform BREAST to the radiologists in Shanghai, to assess their performance and explore the BREAST platform’s potential to transform cancer detection rates and thereby paving the future for optimised breast cancer interpretation. Our team, Dr. Tong Li, Ms Kriscia Tapia and Prof. Patrick Brennan, along with Dr. Qin Xiao (Radiologist from the Department of Radiology, Fudan University Shanghai Cancer Center) and Prof. Yajia Gu will begin this project in November 2019.
