Does RT influence BCSS/ OS ?

• 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% !
