2 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 Source: J Clin Oncol 31, 2013 (suppl; abstr 1121) TARGIT-A trial: Updated results for local recurrence and survival for the German centers Presenter: Frederik K. Wenz January 2013

3 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 Source: J Clin Oncol 31, 2013 (suppl; abstr 1120) Intraoperative versus external beam boost for breast cancer: A matched-pair analysis Presenter: Elena Sperk January 2013

4 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 Source: J Clin Oncol 31, 2013 (suppl; abstr 1108) Intraoperative radiotherapy in early breast cancer: 400 consecutive patients in one institution Presenter: Mariana Steiner January 2013
