Main results of the multidisciplinary panel

Surgery of the breast	acceptable resection margin: 'not touching the ink' for invasive cancer recommendation for oncoplastic surgical techniques in case of resection of >25% of breast tissue acceptance of resection within new tumor extent after nCT
Axilla surgery and pathology	axillary dissection not recommended in case of isolated tumor cells or micrometastasis in the sentinel node no clear recommendation supporting omission of ALND in the presence of macrometastases in the sentinel node acceptance of SNB after nCT in the event of partial or complete clinical remission of the main cancer
Reconstructive surgery	nipple-sparing mastectomy accepted as safe and valid option no recommendation for immediate breast reconstruction with implants for patients with postmastectomy radiotherapy
Radiotherapy	recommendation of postmastectomy radiotherapy in patients with 1–3 positive lymph node and an additional risk factor option of avoiding radiotherapy for low risk patients above the age of 70 in certain cases intraoperative radiotherapy is an option for replacement of external boost no recommendation for hypofractionated or partial breast radiotherapy as clinical routine standard
Imaging	breast MRI as staging tool not recommended for all cases of breast cancer

nCT = neoadjuvant chemotherapy; ALND = axillary lymph node dissection; SNB = sentinel node biopsy; MRI = magnetic resonance imaging.
