Impact of contemporary therapy- concepts on surgical morbidity in breast cancer patients: A retrospective single center analysis of 829 patients.

Introduction: Morbidity after breast cancer surgery remains low with revision surgery below 5%. This retrospective monocentric study investigates whether new methods like neoadjuvant chemotherapy (nCT), oncoplastic surgery (OPS) or intraoperative radiotherapy (IORT) affect overall morbidity. In addition, we sought to determine a possible effect of morbidity on oncologic outcome.
