Brief Summary
Hypofractionated intraoperative boost (HIOB) is defined as hypofractionated WBRT (40.5 Gy in 2.7 Gy per fraction) preceded by an intraoperative boost to the tumor bed (10 Gy IOERT). The HIOB study concept will test whether such a combined schedule is superior or iso-effective standard RT in terms of local control and cosmetic outcome.

Outcome Measures
Primary Outcomes (1)
Assessment of acute and late toxicity
Assessment of acute toxicity of breast irradiation according to CTC-toxicity Scoring - systems: * At the end of Radiation Therapy * At time of first follow-up investigation (week 8 - 10) Assessment of late toxicity according to NSABP scoring - systems at 6, 12, 24, 36, 48, and 60 months

Study Arms (1)
Intraoperative Electron Radiation Therapy
EXPERIMENTALA single dose of electron irradiation given at the surgical site during the operation to remove the cancerous tumor will replace the usual 5-8 days of localized radiation. Hypofractionated Whole Breast Radiation Therapy must start within 14-56 days post operatively.
Interventions
Hypofractionated Whole Breast Radiation Therapy must start within 14-56 days postoperatively (week 2-8 post-op) * Single reference dose per fraction: 2.7 Gy (ICRU) * Number of fractions: 15 * Number of fractions per week: 5 * Regular Radiation Therapy breaks: Weekend/ Holidays (not exceeding 7 days break) * Total dose: 50.5 Gy (40.5 WBRT + 10 Gy boost) Radiation: Intraoperative Electron Radiation Therapy
Intraoperative Electron Radiation Therapy (IOERT) is delivered after completion of the lumpectomy and sentinel node procedure. IOERT is performed on mobile or fixed linac with variable electron energies in the range of 4-12 MeV
Eligibility Criteria
You may qualify if:
- Histological proven invasive breast carcinoma (ductal and lobular)

- Nodal Status: NO-1
- Clear surgical margins: R0; min 2mm. Re-excision after IOERT is permitted but not required to achieve (-) margin.
- All grades G1 - G3
- Any hormonal receptor and Her-2 status
- Informed consent
You may not qualify if:
- In-situ Carcinoma without invasive component or multifocal disease \> 4 cm

- Nodal Status \> N1 pathologically
- Surgical margins \< 2mm
- Multicentricity
- Previous radiotherapy to the involved breast
- Karnofsky Index \< 70%
- Mixed connective tissue diseases e.g. rheumatoid polyarthritis, thromboangitis obliterans, systemic lupus.
- Distant metastases
- Unable to provide written consent
