Lugano-CH, Brussels-BE, 2 May 2013 -- A new analysis has provided a comprehensive comparison of scores designed to predict which women with oestrogen-receptor positive breast cancer are at high risk of recurrence beyond five years after diagnosis, and may benefit from prolonged endocrine treatment.
The promising new findings will likely benefit the many women with oestrogen-receptor positive breast cancer whose cancer recurs more than five years after diagnosis, researchers told the 5th IMPAKT Breast Cancer Conference in Brussels, Belgium.
The IMPAKT meeting presents cutting edge, 'translational' breast cancer research that is beginning to have an impact for patients.
In oestrogen-receptor positive women, half of all recurrences of breast cancer will occur after the women finish the standard 5 years of hormonal treatment, explains lead author Dr Ivana Sestak from the Wolfson Institute of Preventive Medicine in London, UK.
"There is great interest in establishing which women are at adequate high risk of late recurrence after the initial hormonal treatment period, which is currently 5 years," Dr Sestak says.
At the meeting, researchers reported the findings of a comparison of five different scores designed to predict which women may be at increased risk of developing a late recurrence of their cancer. This is the first time that all five scores have been compared within one dataset.
Knowing which women may be at increased risk of developing a late recurrence would enable doctors to identify those women who may be good candidates for extended hormonal therapy, she says.
The ATAC trial included nearly 10,000 women who were treated with surgery followed by five years of treatment with the drugs anastrozole, tamoxifen or a combination of both. Of these 1,125 from the monotherapy arms (tamoxifen, anastrozole) were included in the transATAC study.
