Actual (reported)Number of Patients With Local Recurrence
The follow-up was carried out every six months for the first two years, and then once a year. The follow-up always included a mammography in addition to a clinical examination. Kaplan-Meier-estimates were done to calculate the local recurrence rate

Percentage of Patients With Chronic Higher Grade Fibrosis After IORT Boost
84 months
Boost with 20 Gy during BCS, EBRT with 46-50 Gy
Intraoperative radiotherapy with the INTRABEAM System with 20 Gy
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
All patients with breast cancer and a tumor diameter \< 3,5 cm plannend for breast conserving surgery. Intraoperative radiotherapy (IORT) is applied as an advanced boost with 20 Gy at the applicator surface during surgery. Its feasibility was already shown. IORT as a boost is considered as one of several boost techniques in the S3-Leitlinie (national guideline) for breast cancer.
