Conclusion:

OART in postoperative breast RT is feasible. All adapted TP met the clinical dose requirements. Treatment time was acceptable and reduced upon omitting the influencer as no correction of targets was needed. Manual corrections of the most cranial and caudal target contours had no relevant impact on the dosimetry and could be omitted. This study enables us to develop an RTT-only workflow and explore oART in other breast targets such as locoregional RT.
