Does RT influence BCSS/ OS ?
Donker et al, JCO 2013
•
All meta-analyses (EBCTCG, Stuart et al, Garg et al):
No influence of RT on Breast Cancer Specific Survival (i.e. 97-98%) ,
nor on overall survival
•
However, several studies show:
IF invasive recurrence occurs: BCSS is worse !
15 yr BCSS for invasive LR after biopsy only: 44.8% !
