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

    5 years

Secondary Outcomes (3)

  • Cosmetic Evaluation

    5 years

  • Disease Free Survival

    5 years

  • Overall Survival

    5 Years

Study Arms (1)

Intraoperative Electron Radiation Therapy

EXPERIMENTAL

A 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.

Radiation: Hypofractionated Whole Breast Radiation TherapyRadiation: Intraoperative Electron Radiation Therapy

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

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
