Hypofractionated radiotherapy of the breast 15 × 2.70 Gy with simultaneous integrated boost to the tumor bed (total dose within the boost volume 15 × 3.20 Gy)
Simultaneous integrated boost radiotherapy has been investigated in some malignant tumors and appears to be safe and feasible. However, Hypofractionation with simultaneous integrated boost has been investigating in breast cancer.~Investigators initiated this phase II prospective trial to analyse acute toxicity of hypofractionation with simultaneous integrated boost in patients with early breast cancer.
