Groups/Cohorts Assigned Interventions
IORT with 50 kV x-rays, 20 Gy
Boost with 20 Gy during BCS, EBRT with 46-50 Gy
Radiation: IORT with 50 kV x-rays, 20 Gy
Intraoperative radiotherapy with the INTRABEAM System with 20 Gy

Detailed Description:
Due to quality control of a standard treatment with intraoperative radiotherapy during breast conserving surgery with 20 Gy as an advanced boost followed by a shortened external beam radiotherapy. For all patients there is an informed consent for the irradiation and the data sampling in Germany. All data are collected anonymously at several centers in Germany and sent for analyses to the study center in Mannheim. Due to the nature of the study (registry) there is no need for randomization. Inclusion of n = 1000 patients is planned.

Ages Eligible for Study:   18 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
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 during surgery. Its feasibility was already shown. The IORT as a boost is included in several recommendations for breast cancer treatment (St. Gallen Conference 2011).

Inclusion Criteria:

  • Tumor diameter < 3,5 cm
  • Informed consent

Exclusion Criteria:

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