TY - JOUR T1 - Phyllodes tumour of the breast and margins: How much is enough? JF - Canadian Journal of Surgery JO - CAN J SURG SP - E19 LP - E21 DO - 10.1503/cjs.005718 VL - 62 IS - 1 AU - Samuel Ogunbiyi AU - Andrew Perry AU - Kiran Jakate AU - Jory Simpson AU - Ralph George Y1 - 2019/02/01 UR - http://canjsurg.ca/content/62/1/E19.abstract N2 - Phyllodes breast tumours are fairly uncommon, and they can be benign, borderline or malignant. General surgeons usually encounter them following the surgical excision of a breast lump that had the appearance of a fibroepithelial lesion. The surgeon is then faced with the question of what to do to establish an acceptable treatment margin. In this discussion, we recommend a plan for the management of Phyllodes tumours based on a review of the recent literature, confirmed by a retrospective review of the results from our centre. A negative margin is acceptable treatment following a lumpectomy for Phyllodes tumours. Only patients with a positive margin should undergo a revision. ER -
