title: [The future of breast cancer radiotherapy: From one size fits all to taylor-made treatment].
abstract: Various subgroups of breast tumours have been identified during the last 10 years according to the risk of local relapse. Prognostic factors for local relapse are age, surgical margins, tumour size, Her2 expression and hormonal receptors status. For tumours with a high risk of local relapse, an increased in boost dose or the addition of new drugs (trastuzumab, antiangiogenics, PARP inhibitors) could be considered. For low risk tumours, hypofractionated, accelerated partial breast and intraoperative radiotherapy are being evaluated. The classical schedule (45-50 Gy to the whole gland followed by a boost dose of 16 Gy) is no longer the universal rule. Treatment individualization, according to clinical and biological characteristics of the tumour and - possibly - to the radiobiological profile of the patient, is likely to be the future of breast cancer radiotherapy.
