[Hypofractionated radiotherapy for breast cancer in elderly patients: current evidence and future perspectives].

Adjuvant radiotherapy is the pillar of breast conserving surgery. Its omission is related with a higher risk of local recurrence and of breast cancer related or non-related mortality. It is of paramount importance to guarantee this treatment is fully administered to all patients after breast conserving surgery, including the elderly. In the last three decades several hypofractionated treatment schemes have shown their non-inferiority, allowing for treatment time reduction facilitating adhesion to treatment and reducing radiotherapy burden. This review focuses on the schemes and indications which have been validated by large phase 3 trials and those which are still under evaluation.
