5 years results:•734 patients, 7 centres in Germany •Absolute number of events in TARGIT vs. EBRT :

• Primary outcome: IBR 4 vs. 1 • Exploratory outcome: All recurrences (breast

+axilla+contralateral+distant recurrence) 11 vs. 7• Secondary outcome:

• All deaths 6 vs. 12• Breast Cancer deaths 3 vs. 5• Non-Breast Cancer deaths 3 vs. 7

Message: •The 734 German patients have excellent 5 year outcomes

in both arms of the trial•Survival was better in TARGIT than in EBRT

Matched pair analysis impact on overall survival of IORT boost vs. EBRT boost :

•370 patients with 53 pairs•Medium Follow up: 56 month in IORT vs. 6 month in EBRT•Strong trend towards better overall survival after IORT boost (90.2% vs. 62.3%, p = 0.375)•IBR 1 vs. 1

Message:

•IORT given as a boost seems to have a positive impact on overall survival in breast cancer patients after breast conserving surgery

Single center experience since 2006 IORT only vs. WBRT in low risk early breast cancer patients (in patients with high risk tumor characteristics at final pathology, additional local breast therapy)•400 patients •Medium Follow up: 30 month (43 months in the first 200 patients)•Seven ipsilateral breast failures (1.7%) and one axillary recurrence were observed

Message:

•Center concludes that intraoperative radiotherapy using the Intrabeam system is feasible and may offer an alternative to whole breast RT in low risk breast cancer patients •Clinically significant local morbidity rate is low
