Preliminary Results of Electron Intraoperative Therapy Boost and Hypofractionated External Beam Radiotherapy After Breast-Conserving Surgery in Premenopausal Women

The results of this study have shown that electron intraoperative therapy followed by HEBRT allows for the delivery of a high dose to the tumor bed and an adequate dose to the whole breast. This treatment is feasible, compliance is high, and the rate of acute toxicity and the preliminary data on chronic toxicity seem acceptable.
