Brief Summary:
Quality Control Registry for IORT used as an anticipiated boost with 20 Gy at the applicator surface followed by EBRT

Condition or disease Intervention/treatment
Breast Cancer Radiation: IORT with 50 kV x-rays, 20 Gy

Detailed Description:
Quality Control Registry of a standard treatment with intraoperative radiotherapy during breast conserving surgery with 20 Gy at the applicator surface as an advanced boost followed by a shortened external beam radiotherapy. This is a prospective phase IV study to evaluate real life data of IORT Boost. Study runs in Germany with 13 active centers recruiting. Due to the nature of the study (registry) there is no need for randomization. Inclusion of n = >1000 patients is planned.

Study Population
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.

  • Tumor diameter < 3,5 cm
  • Informed consent

Exclusion Criteria:

  • No informed consent
  • Tumor size > 3,5 cm
  • No indication for a boost
