Background: This short report aims to investigate changes in lifespan of Australian women with breast cancer using the novel average lifespan shortened (ALSS) measure METHODS: We obtained the mortality data of Australian women with breast cancer from the World Health Organization mortality database for the 1990-2015 period. We calculated the age-standardized rate (ASR) according to the World Standard Population. We estimated the ALSS as a ratio of years of life lost in relation to the expected lifespan to examine changes in lifespan of Australian women with breast cancer over the study period.
Results: Over a 25-year period, the ASR of breast cancer deaths decreased from 20.5 to 12.6 deaths per 100,000 women. We observed a decline in ALSS values from 24.0% of their lifespan in 1990 to 22.0% in 2015.
Conclusion: The novel ALSS measure indicates an improvement of two percentage points in the lifespan of Australian women with breast cancer over the study.
