Strut-based accelerated partial breast irradiation: Report of treatment results for 250 consecutive patients at 5Â years from a multicenter retrospective study

The strut-based applicator was designed to simplify APBI compared to interstitial brachytherapy. This report confirms excellent tumor control and survival with low toxicity and supports the evidence that brachytherapy has less normal tissue toxicity than APBI with external beam irradiation.
