Neoadjuvant chemotherapy in breast-conserving surgery -Â Consequences on margin status and excision volumes

The primary goal of the surgeon performing BCS after NACT, to reach tumour-free margins, is not accomplished in one out of four patients. Patients especially at risk are patients with ILC and no pathological tumour response. Excessive resection volumes after NACT do not guarantee tumour-free margins. Further research is necessary to analyze whether we are counterproductive when NACT is given in order to lower resection volumes.
