Absolute 10-year risks (%) of any (locoregional or distant) first recurrence with and without radiotherapy (RT) following breast-conserving surgery (BCS) in pathologically node-negative women by patient and trial characteristics, as estimated by regression modelling of data for 7287 women
Further details are in webappendix pp 27–30. Results for 5-year risks are in webappendix pp 31–34. Bars show 10-year risks in women allocated to BCS only, dark sections show 10-year risks in women allocated to BCS plus RT, light sections show absolute reduction with RT. ER=oestrogen receptor.
