To present the first results of intraoperative irradiation (IORT) in breast cancer with a low-energy photon system used as partial (PBI) or an anticipated boost before whole hypo-fractionated (IORT + WBI), concerning tolerance, side effects, quality life, and patient-reported outcomes. Eighty patients treated Intrabeam® 50 kV X-rays received 20 Gy dose intraoperatively were included. Moderate daily hypofractionation 2.7 15 fractions up to 40.5 was administered if high-risk factors present....
